背景技术Background technique

使用相机等成像装置拍摄时，需要经常调节镜头的对焦位置，以使拍摄目标成像效果达到最好。当使用对焦环调节镜头的对焦位置时，用户需要一边旋转对焦环，一边观察相机显示的对焦效果，从而小心地对准拍摄目标。通过这种方式调节对焦位置，花费的时间往往比较长，对于不熟练的用户可以长达数秒钟，并且用户要时刻盯住相机显示器来检查对焦效果，用户的负担很繁重，其对焦效果依赖于用户使用对焦环的经验和对锐度变化的熟悉度，精度通常不稳定。When shooting with an imaging device such as a camera, it is necessary to frequently adjust the focus position of the lens to achieve the best imaging effect of the shooting target. When using the focus ring to adjust the focus position of the lens, the user needs to rotate the focus ring while observing the focus effect displayed by the camera, so as to carefully aim at the shooting target. Adjusting the focus position in this way often takes a long time. For unskilled users, it can take as long as several seconds, and the user has to stare at the camera monitor to check the focus effect. The user’s burden is heavy and the focus effect depends on The user's experience in using the focus ring and familiarity with sharpness changes usually lead to unstable accuracy.

具体实施方式Detailed ways

本公开提出了一种镜头的控制方法及系统，该控制方法可根据用户对操作部件的操作手势，自动将镜头对焦至相对应的对焦位置，以适应特定的应用场景。The present disclosure proposes a lens control method and system. The control method can automatically focus the lens to a corresponding focus position according to a user's operation gesture on an operating component, so as to adapt to a specific application scenario.

下面将结合实施例和实施例中的附图，对本公开技术方案进行清楚、完整的描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。The technical solutions of the present disclosure will be clearly and completely described below in conjunction with the embodiments and the drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

本公开一实施例的镜头的控制方法，如图1所示，该控制方法包括以下步骤：The lens control method according to an embodiment of the present disclosure, as shown in FIG. 1, the control method includes the following steps:

S101：获取操作部件的基于手势的操作信息。S101: Obtain gesture-based operation information of the operation component.

镜头通常具有至少一个操作部件，例如对焦环(手环、操作环)，用来连续地改变镜头的对焦位置。当用户操作对焦环时，会形成连续地多个动作，连续地的多个动作形成一手势。该手势使对焦环顺序经过多个操作状态，每个操作状态对应一用户动作。与对焦环的这些操作状态对应的操作信息，作为基于手势的操作信息。The lens usually has at least one operating component, such as a focus ring (hand ring, operating ring), which is used to continuously change the focus position of the lens. When the user operates the focus ring, multiple consecutive actions are formed, and multiple consecutive actions form a gesture. This gesture causes the focus ring to sequentially pass through multiple operating states, and each operating state corresponds to a user action. The operation information corresponding to these operation states of the focus ring serves as the operation information based on the gesture.

本实施例针对对焦无穷远(INF)处的场景，提出了一种无穷远(INF)悬停手势，具体包括：This embodiment proposes a hovering gesture at infinity (INF) for a scene focusing at infinity (INF), which specifically includes:

旋转动作：用户将对焦环旋转至朝向无穷远对焦位置方向的极限位置， 该极限位置一般称为无穷远对焦位置墙(INF墙)；Rotation action: the user rotates the focus ring to the extreme position facing the infinity focus position, the extreme position is generally called the infinity focus position wall (INF wall);

停留动作：当对焦环到达该INF墙时，用户停止旋转或松开对焦环，使对焦环停留在INF墙位置。Stay action: When the focus ring reaches the INF wall, the user stops rotating or loosens the focus ring, so that the focus ring stays at the INF wall position.

本实施例中，对焦环到达某个位置是指对焦环的指示线与该位置对准。例如，对焦环到达INF墙是指，对焦环的指示线与INF墙对准。In this embodiment, that the focus ring reaches a certain position means that the indicator line of the focus ring is aligned with the position. For example, when the focus ring reaches the INF wall, it means that the indicator line of the focus ring is aligned with the INF wall.

对应于上述INF悬停手势，对焦环顺序经过下列两个操作状态：Corresponding to the above INF hovering gesture, the focus ring goes through the following two operating states in sequence:

如图2a所示，对焦环向无穷远对焦位置方向旋转至INF墙；As shown in Figure 2a, the focus ring rotates to the INF wall toward the infinity focus position;

如图2b所示，对焦环停留在INF墙位置。As shown in Figure 2b, the focus ring stays at the INF wall position.

对于INF悬停手势，其操作信息包括：移动后的位置和在该位置的停留时间，即INF墙和在INF墙的停留时间。For the INF hovering gesture, its operation information includes: the moved position and the stay time at that position, that is, the INF wall and the stay time on the INF wall.

S102：响应于操作信息，当操作信息与镜头的对焦位置相对应时，将镜头对焦至与操作信息相对应的对焦位置。S102: In response to the operation information, when the operation information corresponds to the focus position of the lens, focus the lens to the focus position corresponding to the operation information.

当获取到基于手势的操作信息后，对操作信息进行判断，以确定操作信息是否与镜头的对焦位置相对应。本实施例中，可根据操作信息与对焦位置对应关系的对应关系表进行上述判断。对应关系表可如下所示：After the operation information based on the gesture is obtained, the operation information is judged to determine whether the operation information corresponds to the focus position of the lens. In this embodiment, the above judgment can be made according to the correspondence table of the correspondence between the operation information and the focus position. The corresponding relationship table can be as follows:

表1Table 1

如图3所示，上述过程具体包括：As shown in Figure 3, the above process specifically includes:

首先判断对焦环的移动方向是否朝向INF对焦位置以及移动后的位置是否是INF墙；First determine whether the moving direction of the focus ring is toward the INF focus position and whether the moved position is an INF wall;

再判断在INF墙的停留时间是否超过了预定停留时间。Then judge whether the stay time on the INF wall exceeds the predetermined stay time.

如果上述条件均成立，则判定操作信息与无穷远处的对焦位置相对应，将镜头对焦至无穷远处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at infinity, and the lens is focused to infinity. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

图3只是一种示例，本实施例的判断顺序不以此为限，任何对上述判断顺序进行调整而形成的方案也包括在内。FIG. 3 is just an example, and the judgment sequence of this embodiment is not limited to this, and any solution formed by adjusting the foregoing judgment sequence is also included.

如图4a和4b所示，当用户对对焦环进行步骤S101中的INF悬停手势操作时，操作信息的移动后的位置为INF墙，停留时间超过了预定停留时间。所以上述操作信息与无穷远处的对焦位置对应，如图4c所示，对 焦环到达至INF对焦位置，镜头自动对焦至无穷远处。As shown in FIGS. 4a and 4b, when the user performs the INF hovering gesture in step S101 on the focus ring, the moved position of the operation information is the INF wall, and the stay time exceeds the predetermined stay time. Therefore, the above operation information corresponds to the focus position at infinity. As shown in Figure 4c, the focus ring reaches the INF focus position, and the lens automatically focuses to infinity.

本实施例的镜头控制方法，根据基于INF悬停手势的操作信息，可将镜头自动对焦至无穷远处。用户只要对对焦环执行INF悬停手势，即可触发自动对焦，镜头即自动对焦至无穷远处。相对于传统的手动对焦、人工判断对焦效果的方式，减少了对焦所需的时间，减轻了用户的负担，并且保证了对焦精度。The lens control method of this embodiment can automatically focus the lens to infinity according to the operation information based on the INF hovering gesture. The user only needs to perform an INF hovering gesture on the focus ring to trigger auto focus, and the lens will automatically focus to infinity. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

图5a和图5b分别是传统手动对焦方式、以及本实施例对焦无穷远处的时序图，横轴是时间，纵轴是镜头的对焦位置。Figures 5a and 5b are timing charts of the traditional manual focusing method and focusing at infinity in this embodiment, respectively. The horizontal axis is time, and the vertical axis is the focus position of the lens.

如图5a所示，其显示了对焦无穷远处的过程中，镜头对焦位置的变化过程：As shown in Figure 5a, it shows the changing process of the lens focus position during the process of focusing at infinity:

时段1：用户向INF对焦位置方向快速旋转对焦环，同时检查成像装置机身屏幕上的画面锐度变化，直至锐度经过最高点；Time period 1: The user quickly rotates the focus ring toward the INF focus position, and at the same time checks the sharpness changes on the screen of the imaging device, until the sharpness passes the highest point;

时段2：用户意识到经过INF对焦位置后，用户减速反向旋转对焦环，再次检查画面锐度变化并寻找锐度最高点；Time period 2: After the user realizes that after passing the INF focus position, the user decelerates and rotates the focus ring in the opposite direction, checks the image sharpness change again and finds the highest point of sharpness;

时段3：若非特别熟练的用户，则会减速反复经过锐度最高点(例如图5a中共4次经过锐度最高点)，从而精确的停止到INF对焦位置。Time period 3: If the user is not particularly skilled, he will slow down and repeatedly pass the highest sharpness point (for example, Figure 5a passes through the highest sharpness point four times), so as to accurately stop to the INF focus position.

上述整个过程的耗时依赖于用户使用对焦环的经验和对锐度变化的熟悉度，一般耗时较长，且精度依赖人眼对锐度变化的判断，精度不稳定。The time-consuming process of the above-mentioned whole process depends on the user's experience in using the focus ring and familiarity with the sharpness change, which generally takes a long time, and the accuracy depends on the human eye's judgment of the sharpness change, and the accuracy is unstable.

图5b显示INF悬停手势下的对焦过程：Figure 5b shows the focusing process under the INF hovering gesture:

时段1：用户快速向INF对焦位置方向旋转对焦环，直至INF墙；Time period 1: The user quickly rotates the focus ring toward the INF focus position until it reaches the INF wall;

时段2：用户停止旋转对焦环，对焦环停留在INF墙一段时间；Time period 2: The user stops rotating the focus ring and the focus ring stays on the INF wall for a period of time;

时段3：自动对焦被触发，镜头自动对焦至无穷远处。Period 3: Autofocus is triggered, and the lens automatically focuses to infinity.

上述整个过程仅仅依赖于INF悬停手势的触发灵敏度，耗时短，而且不需要用户检查锐度变化，对焦精度不依赖人为因素，对焦精度高。The above whole process only relies on the trigger sensitivity of the INF hovering gesture, which takes a short time and does not require the user to check the sharpness changes. The focus accuracy does not depend on human factors and the focus accuracy is high.

以上只是示例性说明，本实施例的镜头控制方法，INF悬停手势不限于旋转动作，也可以是其他动作。例如，当对焦环是通过沿镜头轴向的运动来改变对焦位置时，平移动作代替INF悬停手势的旋转动作。平移动作包括：用户向INF对焦位置平移对焦环，并将对焦环平移至INF墙。这种情况下，INF墙是指镜头轴向上的位置，并非旋转动作那样的镜头周向上的位置。The above is only an exemplary description. In the lens control method of this embodiment, the INF hovering gesture is not limited to a rotating motion, and may also be other motions. For example, when the focus ring changes the focus position by moving along the axis of the lens, the pan movement is used as a rotation action instead of the INF hovering gesture. The translation operation includes: the user translates the focus ring to the INF focus position, and translates the focus ring to the INF wall. In this case, the INF wall refers to the upward position of the lens axis, not the position in the circumferential direction of the lens such as a rotating motion.

本实施例的对应关系表、以及对应关系表中的操作信息、对焦位置等内容均为预先设定，即在镜头使用前已经设定好。预定停留时间可根据INF悬停手势的灵敏度来确定，预定停留时间可以为毫米量级，例如100ms、200ms。但预定停留时间不宜设的过长，以免整个对焦过程的耗时过长，影响用户体验。The correspondence table in this embodiment, and the operation information, focus position and other contents in the correspondence table are all preset, that is, they have been set before the lens is used. The predetermined stay time can be determined according to the sensitivity of the INF hovering gesture, and the predetermined stay time can be on the order of millimeters, such as 100 ms or 200 ms. However, the predetermined stay time should not be set too long, otherwise the entire focusing process will take too long and affect the user experience.

本公开另一实施例的镜头的控制方法，为简要描述，与上一实施例相同或相似的内容不再赘述，以下仅描述其不同于上一实施例的内容。The lens control method of another embodiment of the present disclosure is briefly described, and the content that is the same or similar to the previous embodiment will not be repeated, and only the content that is different from the previous embodiment will be described below.

在获取操作部件的基于手势的操作信息的步骤中，本实施例针对最近对焦距离(MOD)处的场景，提出了一种最近对焦距离(MOD)悬停手势，具体包括：In the step of acquiring the gesture-based operation information of the operating component, this embodiment proposes a hovering gesture at the closest focus distance (MOD) for a scene at the closest focus distance (MOD), which specifically includes:

旋转动作：用户将对焦环旋转至朝向最近对焦距离位置方向的极限位置，该极限位置一般称为最近对焦距离墙(MOD墙)；Rotation action: the user rotates the focus ring to the extreme position in the direction of the closest focusing distance position, which is generally called the closest focusing distance wall (MOD wall);

停留动作：当对焦环到达该MOD墙时，用户停止旋转或松开对焦环，使对焦环停留在MOD墙位置。Hold action: When the focus ring reaches the MOD wall, the user stops rotating or loosens the focus ring, so that the focus ring stays on the MOD wall.

对应于上述MOD悬停手势，对焦环顺序经过下列两个操作状态：Corresponding to the above MOD hovering gesture, the focus ring goes through the following two operating states in sequence:

如图6a所示，对焦环向最近对焦距离位置方向旋转至MOD墙；As shown in Figure 6a, the focus ring rotates to the MOD wall in the direction of the closest focusing distance;

如图6b所示，对焦环停留在MOD墙位置。As shown in Figure 6b, the focus ring stays at the MOD wall position.

对于MOD悬停手势，其操作信息包括：MOD墙和在MOD墙的停留时间。For the MOD hovering gesture, its operation information includes: MOD wall and stay time on the MOD wall.

在响应于操作信息，当操作信息与镜头的对焦位置相对应时，将镜头对焦至与操作信息相对应的对焦位置步骤，本实施例根据操作信息与对焦位置对应关系的对应关系表进行判断，对应关系表可如下所示：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, this embodiment makes a judgment based on the correspondence table of the correspondence between the operation information and the focus position, The corresponding relationship table can be as follows:

表2Table 2

如图7所示，上述过程具体包括：As shown in Figure 7, the above process specifically includes:

首先判断对焦环的移动方向是否朝向MOD位置，以及移动后的位置是否是MOD墙；First determine whether the moving direction of the focus ring is toward the MOD position, and whether the moved position is a MOD wall;

再判断在MOD墙的停留时间是否超过了预定停留时间。Then judge whether the stay time on the MOD wall exceeds the predetermined stay time.

如果上述条件均成立，则判定操作信息与最近对焦距离的对焦位置相 对应，将镜头对焦至最近对焦距离。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If all the above conditions are met, it is determined that the operation information corresponds to the focus position of the closest focusing distance, and the lens is focused to the closest focusing distance. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

与上一实施例类似，图7只是一种示例，本实施例的判断顺序不以此为限，任何对上述判断顺序进行调整而形成的方案也包括在内。Similar to the previous embodiment, FIG. 7 is only an example, and the judgment sequence of this embodiment is not limited to this, and any solution formed by adjusting the foregoing judgment sequence is also included.

如图8a和8b所示，当用户对对焦环执行的MOD悬停手势操作时，操作信息的移动后的位置为MOD墙，停留时间超过了预定停留时间。所以上述操作信息与最近对焦距离的对焦位置对应，如图8c所示，对焦环到达至MOD位置，镜头自动对焦至最近对焦距离处。As shown in Figures 8a and 8b, when the user performs a MOD hovering gesture operation on the focus ring, the moved position of the operation information is the MOD wall, and the stay time exceeds the predetermined stay time. Therefore, the above operation information corresponds to the focus position of the closest focusing distance. As shown in FIG. 8c, the focus ring reaches the MOD position, and the lens automatically focuses to the closest focusing distance.

本实施例的镜头控制方法，根据基于MOD悬停手势的操作信息，可将镜头自动对焦至与最近对焦距离处。用户只要对对焦环执行MOD悬停手势，即可触发自动对焦，镜头即自动对焦至最近对焦距离处。相对于传统的手动对焦、人工判断对焦效果的方式，减少了对焦所需的时间，减轻了用户的负担，并且保证了对焦精度。The lens control method of this embodiment can automatically focus the lens to the closest focusing distance according to the operation information based on the MOD hovering gesture. The user only needs to execute the MOD hovering gesture on the focus ring to trigger auto focus, and the lens will automatically focus to the closest focusing distance. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

本公开又一实施例的镜头的控制方法，为简要描述，与上述实施例相同或相似的内容不再赘述，以下仅描述其不同于上述实施例的内容。The lens control method according to another embodiment of the present disclosure is briefly described, and the content that is the same as or similar to the foregoing embodiment will not be repeated, and only the content that is different from the foregoing embodiment will be described below.

在获取操作部件的基于手势的操作信息的步骤中，本实施例针对对焦无穷远处的场景，提出了一种无穷远(INF)抖动手势，具体包括：In the step of acquiring gesture-based operation information of the operating component, this embodiment proposes an infinity (INF) shaking gesture for a scene focusing at infinity, which specifically includes:

第一旋转动作：用户向MOD位置旋转对焦环第一角度；The first rotation action: the user rotates the focus ring to the MOD position by a first angle;

第二旋转动作：用户向INF位置旋转对焦环第二角度，随后停止旋转对焦环。Second rotation action: the user rotates the focus ring by a second angle to the INF position, and then stops rotating the focus ring.

对应于上述INF抖动手势，对焦环顺序经过下列三个操作状态：Corresponding to the aforementioned INF shaking gesture, the focus ring goes through the following three operating states in sequence:

如图9a所示，对焦环向MOD位置旋转第一角度；As shown in Figure 9a, the focus ring rotates to the MOD position by a first angle;

如图9b所示，对焦环向INF位置旋转第二角度；As shown in Figure 9b, the focus ring rotates a second angle to the INF position;

如图9c所示，对焦环停止旋转。As shown in Figure 9c, the focus ring stops rotating.

对于INF抖动手势，其操作信息包括：对焦环移动的第一方向(朝向MOD位置方向)、第一角度、第二方向(朝向INF位置方向)、第二角度、以及图9a和图9b两个操作状态之间的停顿时间。For the INF shaking gesture, its operation information includes: the first direction (toward the MOD position), the first angle, the second direction (toward the INF position), the second angle of the focus ring movement, and the two of Figure 9a and Figure 9b The pause time between operating states.

在响应于操作信息，当操作信息与镜头的对焦位置相对应时，将镜头对焦至与操作信息相对应的对焦位置的步骤中，当获取到基于手势的操作信息后，对操作信息进行判断，以确定操作信息是否与镜头的对焦位置相 对应。本实施例中，可根据操作信息与对焦位置对应关系的对应关系表进行上述判断。对应关系表可如下所示：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, when the operation information based on the gesture is obtained, the operation information is determined, To determine whether the operation information corresponds to the focus position of the lens. In this embodiment, the above judgment can be made according to the correspondence table of the correspondence between the operation information and the focus position. The corresponding relationship table can be as follows:

表3table 3

如图10所示，上述过程具体包括：As shown in Figure 10, the above process specifically includes:

判断对焦环的移动方向是否朝向MOD位置方向；Determine whether the moving direction of the focus ring faces the MOD position;

判断朝向MOD位置方向移动的第一角度是否位于第一范围；Judging whether the first angle moving toward the MOD position is in the first range;

判断对焦环的移动方向是否朝向INF位置方向；Determine whether the moving direction of the focus ring is toward the INF position;

判断朝向INF位置方向移动的第二角度是否位于第二范围；Judging whether the second angle moved toward the INF position is in the second range;

判断对焦环在第一角度的停顿时间是否位于预定停顿时间范围。It is determined whether the pause time of the focus ring at the first angle is within a predetermined pause time range.

如果上述条件均成立，则判定操作信息与无穷远处的对焦位置相对应，将镜头对焦至无穷远处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at infinity, and the lens is focused to infinity. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

图10只是一种示例，本实施例的判断顺序不以此为限，任何对上述判断顺序进行调整而形成的方案也包括在内。FIG. 10 is just an example, and the judgment sequence of this embodiment is not limited to this, and any solution formed by adjusting the foregoing judgment sequence is also included.

如图11a、11b和11c所示，当用户对对焦环执行INF抖动手势操作时，操作信息的第一方向为朝向MOD位置方向，第一角度位于第一范围，第二方向为朝向INF位置方向，第二角度位于第二范围，停顿时间位于预定停顿时间范围。所以上述操作信息与无穷远处的对焦位置对应，如图11d所示，对焦环到达至INF对焦位置，镜头自动对焦至无穷远处。As shown in Figures 11a, 11b, and 11c, when the user performs an INF shaking gesture operation on the focus ring, the first direction of the operation information is toward the MOD position, the first angle is in the first range, and the second direction is toward the INF position. , The second angle is located in the second range, and the pause time is located in the predetermined pause time range. Therefore, the above operation information corresponds to the focus position at infinity. As shown in FIG. 11d, the focus ring reaches the INF focus position, and the lens automatically focuses to infinity.

本实施例的镜头控制方法，根据基于INF抖动手势的操作信息，可将镜头自动对焦至无穷远处。用户只要对对焦环执行INF抖动手势，即可触发自动对焦，镜头即自动对焦至无穷远处。相对于传统的手动对焦、人工判断对焦效果的方式，减少了对焦所需的时间，减轻了用户的负担，并且保证了对焦精度。The lens control method of this embodiment can automatically focus the lens to infinity according to the operation information based on the INF shaking gesture. The user only needs to perform an INF shaking gesture on the focus ring to trigger auto focus, and the lens will automatically focus to infinity. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

图12显示了INF抖动手势下的对焦过程：Figure 12 shows the focus process under the INF shaking gesture:

时段1：用户快速向MOD位置方向旋转对焦环一个小的角度，立刻快速向INF位置方向旋转对焦环一个小的角度，然后停止旋转；Time period 1: The user quickly rotates the focus ring to the MOD position by a small angle, then quickly rotates the focus ring to the INF position by a small angle, and then stops rotating;

时段2：INF抖动手势被触发，镜头自动移动对焦位置到无穷远处。Time period 2: The INF shaking gesture is triggered, and the lens automatically moves the focus position to infinity.

与INF悬停手势类似，相对于传统的手动对焦、人工判断对焦效果的方式，本实施例减少了对焦所需的时间，减轻了用户的负担，无需用户检查画面锐度变化，并且保证了对焦精度。Similar to the INF hovering gesture, compared to the traditional manual focusing and manual judgment of the focusing effect, this embodiment reduces the time required for focusing, reduces the burden on the user, does not require the user to check the sharpness changes of the picture, and ensures the focus Accuracy.

以上只是示例性说明，与INF悬停手势类似，本实施例的镜头控制方法，INF抖动手势不限于旋转动作，也可以是其他动作。实际上，在本实施例，INF抖动手势只要包括如下动作即可：The above is only an exemplary description. Similar to the INF hovering gesture, in the lens control method of this embodiment, the INF shaking gesture is not limited to a rotating motion, and may also be other motions. In fact, in this embodiment, the INF shaking gesture only needs to include the following actions:

用户将对焦环向第一方向移动第一移动量；The user moves the focus ring in the first direction by a first movement amount;

用户将对焦环向第二方向移动第二移动量；第二方向与第一方向相反，随后停止旋转对焦环。The user moves the focus ring in the second direction by a second amount of movement; the second direction is opposite to the first direction, and then stops rotating the focus ring.

对应地，对焦环包括以下操作状态：Correspondingly, the focus ring includes the following operating states:

对焦环沿第一方向移动第一移动量；The focus ring moves along the first direction by a first movement amount;

对焦环沿第二方向移动第二移动量，所述第二方向与所述第一方向相反。The focus ring moves in a second direction by a second amount of movement, and the second direction is opposite to the first direction.

与此对应的操作信息包括：第一方向、第一移动量、第二方向、第二移动量以及两个操作状态之间的停顿时间。The operation information corresponding to this includes: the first direction, the first movement amount, the second direction, the second movement amount, and the pause time between the two operation states.

例如，当对焦环是通过沿镜头轴向的运动来改变对焦位置时，上述移动指的是平移，第一移动量和第二移动量是指距离。For example, when the focus ring changes the focus position by moving along the lens axis, the above movement refers to translation, and the first movement amount and the second movement amount refer to distance.

当对焦环旋转移动时，第一范围和第二范围是一角度范围；当对焦环平移移动时，第一范围和第二范围是一距离范围。第一范围、第二范围和预定停顿时间范围可以根据INF抖动手势的灵敏度来确定。例如，当对焦环旋转移动时，第一范围、第二范围可以是5°至30°；当对焦环平移移动时，第一范围、第二范围可以是10mm至20mm。第一范围和第二范围可以相同也可以不同。预定停顿时间范围不宜过长，可以是0.5s至1s。When the focus ring rotates and moves, the first range and the second range are angle ranges; when the focus ring moves in translation, the first range and the second range are distance ranges. The first range, the second range, and the predetermined pause time range may be determined according to the sensitivity of the INF shaking gesture. For example, when the focus ring rotates and moves, the first range and the second range may be 5° to 30°; when the focus ring moves in translation, the first range and the second range may be 10 mm to 20 mm. The first range and the second range may be the same or different. The predetermined pause time range should not be too long, it can be 0.5s to 1s.

在本实施例中，INF抖动手势也不限于包括两个移动动作，其可以包括三个以上的多个移动动作。对应地，对焦环包括多个操作状态。例如，当用户旋转对焦环时，INF抖动手势可以包括：In this embodiment, the INF shaking gesture is not limited to including two movement actions, and it may include more than three movement actions. Correspondingly, the focus ring includes multiple operating states. For example, when the user rotates the focus ring, the INF shaking gesture can include:

第一旋转动作：用户向MOD位置旋转对焦环第一角度；The first rotation action: the user rotates the focus ring to the MOD position by a first angle;

第二旋转动作：用户向INF位置旋转对焦环第二角度；Second rotation action: the user rotates the focus ring to the INF position by a second angle;

第三旋转动作：用户再向MOD位置旋转对焦环第三角度，随后停止旋转对焦环。Third rotation action: the user rotates the focus ring to the MOD position by a third angle, and then stops rotating the focus ring.

对应于上述INF抖动手势，对焦环顺序经过下列四个操作状态：Corresponding to the aforementioned INF shaking gesture, the focus ring goes through the following four operating states in sequence:

对焦环向MOD位置旋转第一角度；The focus ring rotates a first angle to the MOD position;

对焦环向INF位置旋转第二角度；The focus ring rotates to the INF position by a second angle;

对焦环再向MOD位置旋转第三角度；The focus ring rotates a third angle to the MOD position;

对焦环停止旋转。The focus ring stops rotating.

相应地，对应关系表如下所示：Correspondingly, the correspondence table is as follows:

表4Table 4

相应地，判断操作信息是否与镜头的对焦位置相对应包括：Correspondingly, determining whether the operation information corresponds to the focus position of the lens includes:

判断对焦环的移动方向是否朝向MOD位置方向；Determine whether the moving direction of the focus ring faces the MOD position;

判断朝向MOD位置方向移动的第一角度是否位于第一范围；Judging whether the first angle moving toward the MOD position is in the first range;

判断对焦环的移动方向是否朝向INF位置方向；Determine whether the moving direction of the focus ring is toward the INF position;

判断朝向INF位置方向移动的第二角度是否位于第二范围；Judging whether the second angle moved toward the INF position is in the second range;

判断对焦环的移动方向是否朝向MOD位置方向；Determine whether the moving direction of the focus ring faces the MOD position;

判断朝向MOD位置方向移动的第一角度是否位于第三范围；Determine whether the first angle moving toward the MOD position is in the third range;

判断对焦环在第一角度的停顿时间是否位于第一预定停顿时间范围，在第二角度的停顿时间是否位于第二预定停顿时间范围。Determine whether the pause time of the focus ring at the first angle is within the first predetermined pause time range, and whether the pause time at the second angle is within the second predetermined pause time range.

如果上述条件均成立，则判定操作信息与无穷远处的对焦位置相对应，将镜头对焦至无穷远处。如果有一个条件不成立，则镜头的对焦位置不发 生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at infinity, and the lens is focused to infinity. If one of the conditions is not established, the focus position of the lens will not change, and it will wait to respond to the next operation information.

由此可见，在本实施例中，当INF抖动手势包括三个以上的多个移动动作时，只要对焦环任意相邻的两个操作状态各向相反方向移动，即可实现自动对焦。对于对焦环平移等移动方式，与上述情况类似，在此不再赘述。It can be seen that, in this embodiment, when the INF shaking gesture includes more than three multiple movement actions, as long as any two adjacent operating states of the focus ring move in opposite directions, auto focus can be achieved. For the movement modes such as the translation of the focus ring, it is similar to the above-mentioned situation, and will not be repeated here.

本公开再一实施例的镜头的控制方法，为简要描述，与上述实施例相同或相似的内容不再赘述，以下仅描述其不同于上述实施例的内容。The lens control method according to still another embodiment of the present disclosure is briefly described, and the content that is the same as or similar to the foregoing embodiment will not be repeated, and only the content that is different from the foregoing embodiment will be described below.

在获取操作部件的基于手势的操作信息的步骤中，本实施例针对最近对焦距离的场景，提出了一种最近对焦距离(MOD)抖动手势，具体包括：In the step of acquiring the gesture-based operation information of the operating component, this embodiment proposes a closest focus distance (MOD) shaking gesture for the scene of the closest focus distance, which specifically includes:

第一旋转动作：用户向INF位置旋转对焦环第一角度；The first rotation action: the user rotates the focus ring to the INF position by a first angle;

第二旋转动作：用户向MOD位置旋转对焦环第二角度，随后停止旋转对焦环。Second rotation action: the user rotates the focus ring by a second angle to the MOD position, and then stops rotating the focus ring.

对应于上述MOD抖动手势，对焦环顺序经过下列三个操作状态：Corresponding to the aforementioned MOD shaking gesture, the focus ring goes through the following three operating states in sequence:

如图13a所示，对焦环向INF位置旋转第一角度；As shown in Figure 13a, the focus ring rotates to the INF position by a first angle;

如图13b所示，对焦环向MOD位置旋转第二角度；As shown in Figure 13b, the focus ring rotates a second angle to the MOD position;

如图13c所示，对焦环停止旋转。As shown in Figure 13c, the focus ring stops rotating.

对于MOD抖动手势，其操作信息包括：对焦环移动的第一方向(朝向INF位置方向)、第一角度、第二方向(朝向MOD位置方向)、第二角度、以及图13a和图13b两个操作状态之间的停顿时间。For the MOD shaking gesture, its operation information includes: the first direction (toward the INF position), the first angle, the second direction (toward the MOD position), the second angle of the focus ring movement, and the two of Figure 13a and Figure 13b The pause time between operating states.

本实施例可根据操作信息与对焦位置对应关系的对应关系表判断操作信息是否与镜头的对焦位置是否相对应。对应关系表可如下所示：In this embodiment, it can be determined whether the operation information corresponds to the focus position of the lens according to the correspondence table of the correspondence between the operation information and the focus position. The corresponding relationship table can be as follows:

表5table 5

如图14所示，上述过程具体包括：As shown in Figure 14, the above process specifically includes:

判断对焦环的移动方向是否朝向INF位置方向；Determine whether the moving direction of the focus ring is toward the INF position;

判断朝向INF位置方向移动的第一角度是否位于第一范围；Judging whether the first angle moving toward the INF position is in the first range;

判断对焦环的移动方向是否朝向MOD位置方向；Determine whether the moving direction of the focus ring faces the MOD position;

判断朝向MOD位置方向移动的第二角度是否位于第二范围；Judging whether the second angle moving toward the MOD position is in the second range;

判断对焦环在第一角度的停顿时间是否位于预定停顿时间范围。It is determined whether the pause time of the focus ring at the first angle is within a predetermined pause time range.

如果上述条件均成立，则判定操作信息与最近对焦距离位置相对应，如图13d所示，将镜头自动对焦至最近对焦距离处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If the above conditions are all met, it is determined that the operation information corresponds to the closest focusing distance position, as shown in FIG. 13d, and the lens is automatically focused to the closest focusing distance. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

本实施例的镜头控制方法，根据基于MOD抖动手势的操作信息，可将镜头自动对焦至最近对焦距离处。用户只要对对焦环执行MOD抖动手势，即可触发自动对焦，镜头即自动对焦至最近对焦距离处。相对于传统的手动对焦、人工判断对焦效果的方式，减少了对焦所需的时间，减轻了用户的负担，并且保证了对焦精度。The lens control method of this embodiment can automatically focus the lens to the closest focusing distance according to the operation information based on the MOD shaking gesture. The user only needs to perform a MOD shaking gesture on the focus ring to trigger auto focus, and the lens will automatically focus to the closest focusing distance. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

与上一实施例类似，在本实施例中，当MOD抖动手势包括三个以上的多个移动动作时，只要对焦环任意相邻的两个操作状态各向相反方向移动，即可实现自动对焦。对于对焦环平移等移动方式，与上述情况类似，在此不再赘述。Similar to the previous embodiment, in this embodiment, when the MOD shaking gesture includes more than three multiple movement actions, as long as any two adjacent operating states of the focus ring move in opposite directions, auto focus can be achieved. . For the movement modes such as the translation of the focus ring, it is similar to the above-mentioned situation, and will not be repeated here.

本公开再一实施例的镜头的控制方法，为简要描述，与上述实施例相同或相似的内容不再赘述，以下仅描述其不同于上述实施例的内容。The lens control method according to still another embodiment of the present disclosure is briefly described, and the content that is the same as or similar to the foregoing embodiment will not be repeated, and only the content that is different from the foregoing embodiment will be described below.

在获取操作部件的基于手势的操作信息的步骤中，本实施例提出了一种镜头重置手势，具体包括：In the step of obtaining gesture-based operation information of the operating component, this embodiment proposes a lens reset gesture, which specifically includes:

第一旋转动作：用户向MOD位置旋转对焦环至MOD墙；The first rotation action: the user rotates the focus ring to the MOD wall to the MOD position;

第二旋转动作：用户向INF位置旋转对焦环至INF墙，随后停止旋转对焦环。Second rotation action: the user rotates the focus ring to the INF wall to the INF position, and then stops rotating the focus ring.

当用户在使用镜头的过程中，遇到想要重置镜头的情况，可以采用上述手势来重置镜头。重置镜头后，镜头将对焦至重置对焦状态。该重置对焦状态预先设定，是镜头启动或重启后的对焦位置。When the user encounters a situation where he wants to reset the lens while using the lens, he can use the above gesture to reset the lens. After resetting the lens, the lens will focus to the reset focus state. The reset focus state is preset, which is the focus position after the lens is started or restarted.

对应于上述镜头重置手势，对焦环顺序经过下列操作状态：Corresponding to the above lens reset gesture, the focus ring sequentially goes through the following operating states:

如图15a所示，对焦环向MOD位置旋转至MOD墙；As shown in Figure 15a, the focus ring rotates to the MOD position to the MOD wall;

如图15b所示，对焦环向INF位置旋转至INF墙，之后停止旋转。As shown in Figure 15b, the focus ring rotates to the INF position to the INF wall, and then stops rotating.

对于镜头重置手势，其操作信息包括：对焦环移动的第一方向(朝向 MOD位置方向)、第一位置、第二方向(朝向INF位置方向)、第二位置、以及图15a和图15b两个操作状态之间的停顿时间。For the lens reset gesture, the operation information includes: the first direction of the focus ring movement (toward the MOD position), the first position, the second direction (toward the INF position), the second position, and the two of Figures 15a and 15b The pause time between operating states.

在响应于操作信息，当操作信息与镜头的对焦位置相对应时，将镜头对焦至与操作信息相对应的对焦位置的步骤中，当获取到基于手势的操作信息后，对操作信息进行判断，以确定操作信息是否与镜头的对焦位置相对应。本实施例中，可根据操作信息与对焦位置对应关系的对应关系表进行上述判断。对应关系表可如下所示：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, when the operation information based on the gesture is obtained, the operation information is determined, To determine whether the operation information corresponds to the focus position of the lens. In this embodiment, the above judgment can be made according to the correspondence table of the correspondence between the operation information and the focus position. The corresponding relationship table can be as follows:

表6Table 6

如图16所示，上述过程具体包括：As shown in Figure 16, the above process specifically includes:

判断对焦环的移动方向是否朝向MOD位置方向；Determine whether the moving direction of the focus ring faces the MOD position;

判断对焦环是否到达MOD墙；Determine whether the focus ring reaches the MOD wall;

判断对焦环是否到达INF墙；Determine whether the focus ring reaches the INF wall;

判断对焦环在MOD墙的停顿时间是否位于预定停顿时间范围。Determine whether the pause time of the focus ring on the MOD wall is within the predetermined pause time range.

如果上述条件均成立，则判定操作信息与重置对焦状态相对应，如图15所示，将镜头自动对焦至无穷远处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If the above conditions are all met, it is determined that the operation information corresponds to the reset focus state, as shown in FIG. 15, the lens is automatically focused to infinity. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

图16只是一种示例，本实施例的判断顺序不以此为限，任何对上述判断顺序进行调整而形成的方案也包括在内。FIG. 16 is just an example, and the judgment sequence of this embodiment is not limited to this, and any solution formed by adjusting the foregoing judgment sequence is also included.

本实施例的镜头控制方法，根据基于镜头重置手势的操作信息，可将镜头自动重置。用户只要对对焦环执行镜头重置手势，即可触发自动对焦，镜头即自动对焦至重置对焦状态处。相对于传统的手动对焦、人工判断对焦效果的方式，减少了对焦所需的时间，减轻了用户的负担，并且保证了对焦精度。According to the lens control method of this embodiment, the lens can be automatically reset according to the operation information based on the lens reset gesture. The user only needs to perform a lens reset gesture on the focus ring to trigger auto focus, and the lens will automatically focus to the reset focus state. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

上述只是示例性说明，在本实施例中，INF和MOD可以互换。即对焦环先向INF位置旋转至INF墙，再向MOD位置旋转至MOD墙。具体控制过程与上述描述类似，在此不再赘述。The foregoing is only an exemplary description. In this embodiment, INF and MOD can be interchanged. That is, the focus ring first rotates to the INF position to the INF wall, and then rotates to the MOD position to the MOD wall. The specific control process is similar to the above description, and will not be repeated here.

本公开再一实施例的镜头的控制方法，为简要描述，与上述实施例相同或相似的内容不再赘述，以下仅描述其不同于上述实施例的内容。The lens control method according to still another embodiment of the present disclosure is briefly described, and the content that is the same as or similar to the foregoing embodiment will not be repeated, and only the content that is different from the foregoing embodiment will be described below.

本实施例的控制方法还包括：The control method of this embodiment further includes:

步骤S001：获取自定义操作信息以及自定义对焦位置的至少其中之一；Step S001: Acquire at least one of the custom operation information and the custom focus position;

步骤S002：根据所述自定义操作信息以及所述自定义对焦位置的至少其中之一，更新所述对应关系表。Step S002: Update the correspondence table according to at least one of the customized operation information and the customized focus position.

本实施例中，除了无穷远处、最近对焦距离处、以及重置对焦状态处，用户可以自己设定对焦位置，这一般可以通过在机身上操作实现。当镜头使用时，其与机身耦合形成一成像装置。机身上具有供用户操作的部件，例如按键、旋钮、触摸面板等。In this embodiment, in addition to the infinity, the closest focusing distance, and the reset focus state, the user can set the focus position by himself, which can generally be achieved by operating on the body. When the lens is used, it is coupled with the body to form an imaging device. The body has parts for users to operate, such as buttons, knobs, touch panels, etc.

用户可以通过上述部件设定自定义对焦位置、以及需要更新的手势。该自定义对焦位置、以及该手势会发送给镜头，然用将该自定义对焦位置更新基于该手势的操作信息所对应的对应关系表。The user can set a custom focus position and gestures that need to be updated through the above components. The custom focus position and the gesture are sent to the lens, and the custom focus position is used to update the correspondence table corresponding to the operation information based on the gesture.

自定义对焦位置介于无穷远与最近对焦位置之间。例如，如果用户设定的自定义对焦位置为3m，其想要更新INF悬停手势。本实施例获取将该3m的自定义对焦位置、以及INF悬停手势，并用该3m的自定义对焦位置更新INF悬停手势对应的对应关系表，即表1。将表1中的对焦位置由无穷远处修改为3m处。更新后的表1如下所示：The custom focus position is between infinity and the closest focus position. For example, if the custom focus position set by the user is 3m, he wants to update the INF hovering gesture. In this embodiment, the 3m custom focus position and the INF hovering gesture are acquired, and the 3m custom focus position is used to update the correspondence table corresponding to the INF hovering gesture, that is, Table 1. Modify the focus position in Table 1 from infinity to 3m. The updated Table 1 is as follows:

表7Table 7

在响应于所述操作信息，当所述操作信息与所述镜头的对焦位置相对应时，将所述镜头对焦至与所述操作信息相对应的对焦位置的步骤中，根据更新后的对应关系表确定操作信息是否与镜头的对焦位置相对应。具体包括：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, according to the updated correspondence relationship The table determines whether the operation information corresponds to the focus position of the lens. Specifically:

判断对焦环的移动方向是否朝向INF对焦位置，以及移动后的位置是否是INF墙；Determine whether the moving direction of the focus ring is toward the INF focus position, and whether the moved position is an INF wall;

判断在INF墙的停留时间是否超过了预定停留时间。Determine whether the stay time on the INF wall exceeds the predetermined stay time.

如果上述条件均成立，则判定操作信息与3m处的对焦位置相对应，将镜头对焦至3m处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at 3m, and the lens is focused to 3m. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

用户还可以通过机身的上述部件设定自定义手势、以及需要更新的手势。该自定义手势、以及该需要更新的手势会发送给镜头，然用将该自定义手势更新基于该需要更新的手势的操作信息所对应的对应关系表。Users can also set custom gestures and gestures that need to be updated through the above components of the body. The custom gesture and the gesture that needs to be updated are sent to the lens, and then the custom gesture is used to update the correspondence table based on the operation information of the gesture that needs to be updated.

例如，如果用户想要用自定义手势更新INF悬停手势，例如，该自定义手势可以是：先向INF对焦位置旋转对焦环第一角度，继续向INF对焦位置旋转对焦环第二角度，最后移动至INF墙，等等。本实施例获取该自定义手势、以及INF悬停手势，并用该自定义手势的操作信息更新INF悬停手势对应的对应关系表，即表1。将表1中的操作信息修改为自定义手势的操作信息。更新后的表1如下所示：For example, if the user wants to update the INF hovering gesture with a custom gesture, for example, the custom gesture can be: first rotate the focus ring to the INF focus position by the first angle, continue to rotate the focus ring to the INF focus position by the second angle, and finally Move to the INF wall, etc. This embodiment acquires the custom gesture and the INF hovering gesture, and uses the operation information of the custom gesture to update the corresponding relationship table of the INF hovering gesture, that is, Table 1. Modify the operation information in Table 1 to the operation information of the custom gesture. The updated Table 1 is as follows:

表8Table 8

在响应于所述操作信息，当所述操作信息与所述镜头的对焦位置相对应时，将所述镜头对焦至与所述操作信息相对应的对焦位置的步骤中，根据更新后的对应关系表确定操作信息是否与镜头的对焦位置相对应。具体包括：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, according to the updated correspondence relationship The table determines whether the operation information corresponds to the focus position of the lens. Specifically:

判断移动后的位置是否是INF墙；Determine whether the moved position is an INF wall;

判断在INF墙的停留时间是否超过了预定停留时间。Determine whether the stay time on the INF wall exceeds the predetermined stay time.

如果上述条件均成立，则判定操作信息与无穷远处的对焦位置相对应，将镜头对焦至无穷远处。如果有一个条件不成立，则镜头的对焦位置不发 生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at infinity, and the lens is focused to infinity. If one of the conditions is not established, the focus position of the lens will not change, and it will wait to respond to the next operation information.

以上只是示例性说明，本实施例还可以对表2至表6中任何一个进行更新，具体方式与上述过程类似，在此不再赘述。The foregoing is only an exemplary description. In this embodiment, any one of Table 2 to Table 6 may also be updated. The specific method is similar to the foregoing process, and will not be repeated here.

用户还可以通过机身的上述部件设定自定义手势和自定义对焦位置。该自定义手势和自定义对焦位置会发送给镜头，然用更新对应关系表。Users can also set custom gestures and custom focus positions through the aforementioned parts of the body. The custom gesture and custom focus position will be sent to the lens, and then the correspondence table will be updated.

例如，如果用户想要用自定义手势来自动对焦至3m的自定义对焦位置。该自定义手势可以是：先向INF对焦位置旋转对焦环第一角度，继续向INF对焦位置旋转对焦环第二角度，最后移动至INF墙，等等。本实施例获取该自定义手势、以及3m自定义对焦位置，并将该自定义手势与3m自定义对焦位置的对应关系添加至对应关系表。对应关系表的如下所示：For example, if the user wants to use a custom gesture to automatically focus to a custom focus position of 3m. The custom gesture may be: first rotate the focus ring to the INF focus position by the first angle, continue to rotate the focus ring to the INF focus position by the second angle, and finally move to the INF wall, and so on. In this embodiment, the custom gesture and the 3m custom focus position are acquired, and the correspondence between the custom gesture and the 3m custom focus position is added to the correspondence table. The corresponding relationship table is as follows:

表9Table 9

在响应于所述操作信息，当所述操作信息与所述镜头的对焦位置相对应时，将所述镜头对焦至与所述操作信息相对应的对焦位置的步骤中，根据更新后的对应关系表确定操作信息是否与镜头的对焦位置相对应。具体包括：In response to the operation information, when the operation information corresponds to the focus position of the lens, in the step of focusing the lens to the focus position corresponding to the operation information, according to the updated correspondence relationship The table determines whether the operation information corresponds to the focus position of the lens. Specifically:

判断对焦环移动的角度是否处于预定角度范围；Determine whether the moving angle of the focus ring is within a predetermined angle range;

判断移动后的位置是否是INF墙；Determine whether the moved position is an INF wall;

判断在INF墙的停留时间是否超过了预定停留时间。Determine whether the stay time on the INF wall exceeds the predetermined stay time.

如果上述条件均成立，则判定操作信息与3m处的对焦位置相对应，将镜头对焦至3m处。如果有一个条件不成立，则镜头的对焦位置不发生变化，等待响应下一次的操作信息。If all the above conditions are satisfied, it is determined that the operation information corresponds to the focus position at 3m, and the lens is focused to 3m. If one of the conditions is not established, the focus position of the lens does not change, and it waits to respond to the next operation information.

The user only needs to perform a gesture on the focus ring to trigger auto focus. Compared with the traditional manual focusing and manual judgment of the focusing effect, the time required for focusing is reduced, the burden on the user is reduced, and the focusing accuracy is ensured.

本公开再一实施例的镜头的控制系统，为简要描述，与上一实施例相同或相似的内容不再赘述，以下仅描述其不同于上一实施例的内容。The lens control system of another embodiment of the present disclosure is briefly described, and the same or similar content as the previous embodiment will not be repeated here, and only the content that is different from the previous embodiment will be described below.

如图18所示，本实施例的控制系统还包括：输入部件，用于获取自定义操作信息以及自定义对焦位置的至少其中之一；As shown in FIG. 18, the control system of this embodiment further includes: an input component for acquiring at least one of custom operation information and custom focus position;

控制部件根据所述自定义操作信息以及所述自定义对焦位置的至少其中之一，更新所述对应关系表。The control component updates the correspondence table according to at least one of the customized operation information and the customized focus position.

当镜头使用时，其与机身耦合形成一成像装置。此时输入部件为一数据接口。机身上具有供用户操作的部件，例如按键、旋钮、触摸面板等。用户通过上述部件设定的自定义操作信息和自定义对焦位置通过数据接口发送给控制部件。When the lens is used, it is coupled with the body to form an imaging device. At this time, the input component is a data interface. The body has parts for users to operate, such as buttons, knobs, touch panels, etc. The custom operation information and the custom focus position set by the user through the above components are sent to the control component through the data interface.

当输入部件收到自定义对焦位置、以及需要更新的手势时，其将该自定义对焦位置、以及该手势会发送给控制部件。控制部件将该自定义对焦位置更新基于该手势的操作信息所对应的对应关系表，并将更新后的对应关系表存储于存储部件。When the input component receives the custom focus position and the gesture that needs to be updated, it sends the custom focus position and the gesture to the control component. The control component updates the correspondence table corresponding to the operation information based on the gesture with the custom focus position, and stores the updated correspondence table in the storage component.

例如，如果用户设定的自定义对焦位置为3m，其想要更新INF悬停手势。控制部件用该3m的自定义对焦位置更新INF悬停手势对应的对应关系表。控制部件对基于手势的操作信息进行判断，包括对焦环的移动方向是否朝向INF对焦位置、移动后的位置是否是INF墙、在INF墙的停留时间是否超过了预定停留时间。如果上述条件均成立，则控制部件判定操作信息与3m处的对焦位置相对应，向驱动部件发送指令。驱动部件将镜头对焦至3m处。For example, if the custom focus position set by the user is 3m, he wants to update the INF hovering gesture. The control component updates the correspondence table corresponding to the INF hovering gesture with the 3m custom focus position. The control component judges the operation information based on the gesture, including whether the moving direction of the focus ring is toward the INF focus position, whether the moved position is an INF wall, and whether the stay time on the INF wall exceeds the predetermined stay time. If the above conditions are all met, the control unit determines that the operation information corresponds to the focus position at 3 m, and sends an instruction to the drive unit. The drive unit focuses the lens to 3m.

当输入部件收到自定义手势、以及需要更新的手势时，其将该自定义手势、以及该手势会发送给控制部件。控制部件将该自定义手势更新需要更新的手势的操作信息所对应的对应关系表，并将更新后的对应关系表存储于存储部件。When the input component receives the custom gesture and the gesture that needs to be updated, it sends the custom gesture and the gesture to the control component. The control component updates the corresponding relationship table corresponding to the operation information of the gesture that needs to be updated with the custom gesture, and stores the updated corresponding relationship table in the storage component.

例如，如果用户想要更新INF悬停手势，控制部件用自定义手势更新INF悬停手势对应的对应关系表。控制部件对基于手势的操作信息进行判断，如果上述操作信息与无穷远处的对焦位置对应，则控制部件向驱动部件发送指令。驱动部件将镜头对焦至无穷远处。For example, if the user wants to update the INF hovering gesture, the control component uses a custom gesture to update the correspondence table corresponding to the INF hovering gesture. The control component judges the operation information based on the gesture, and if the above-mentioned operation information corresponds to the focus position at infinity, the control component sends an instruction to the driving component. The drive unit focuses the lens to infinity.

当输入部件收到自定义手势和自定义对焦位置时，其将该自定义手势和自定义对焦位置会发送给控制部件。When the input component receives the custom gesture and the custom focus position, it sends the custom gesture and the custom focus position to the control component.

控制部件将该自定义手势与自定义对焦位置的对应关系添加至对应 关系表并存储于存储部件。The control component adds the correspondence between the custom gesture and the custom focus position to the correspondence table and stores it in the storage component.

例如，如果用户想要用自定义手势来自动对焦至3m的自定义对焦位置。该自定义手势可以是：先向INF对焦位置旋转对焦环第一角度，继续向INF对焦位置旋转对焦环第二角度，最后移动至INF墙，等等。本实施例获取该自定义手势、以及3m自定义对焦位置，并将该自定义手势与3m自定义对焦位置的对应关系添加至对应关系表。For example, if the user wants to use a custom gesture to automatically focus to a custom focus position of 3m. The custom gesture may be: first rotate the focus ring to the INF focus position by the first angle, continue to rotate the focus ring to the INF focus position by the second angle, and finally move to the INF wall, and so on. In this embodiment, the custom gesture and the 3m custom focus position are acquired, and the correspondence between the custom gesture and the 3m custom focus position is added to the correspondence table.

控制部件根据更新后的对应关系表确定操作信息是否与镜头的对焦位置相对应，包括：对焦环的移动方向是否朝向INF对焦位置、对焦环移动的角度是否处于预定角度范围、对焦环的移动方向是否朝向INF对焦位置、移动后的位置是否是INF墙、在INF墙的停留时间是否超过了预定停留时间。如果上述条件均成立，则控制部件判定操作信息与3m处的对焦位置相对应，向驱动部件发送指令。驱动部件根据该指令将镜头对焦至3m处。The control component determines whether the operation information corresponds to the focus position of the lens according to the updated correspondence table, including: whether the movement direction of the focus ring is toward the INF focus position, whether the movement angle of the focus ring is within a predetermined angle range, and the movement direction of the focus ring Whether it faces the INF focus position, whether the moved position is an INF wall, whether the stay time on the INF wall exceeds the predetermined stay time. If the above conditions are all met, the control unit determines that the operation information corresponds to the focus position at 3 m, and sends an instruction to the drive unit. The drive unit focuses the lens to 3m according to the instruction.

本实施例的控制系统，除了对焦时间短、用户操作简单、对焦精度高的效果外，可以通过自定义的方式，使用任何手势对焦至任何位置，提高了对焦的便利性和灵活性，对各种应用场景的适应性大大增强。In addition to the effects of short focusing time, simple user operation, and high focusing accuracy, the control system of this embodiment can use any gesture to focus to any position in a customized manner, which improves the convenience and flexibility of focusing. The adaptability of this application scenario is greatly enhanced.

需要说明的是，所述输入部件不仅可以是数据接口，也可以是设置于镜筒上的按键、旋钮、触摸屏等。这种情况下，本实施例的控制系统无需机身的配合，自身即可实现用户自定义对焦位置和操作信息。It should be noted that the input component can be not only a data interface, but also a button, a knob, a touch screen, etc. provided on the lens barrel.
