Being described below in detail embodiments of the present invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element from start to finish or has the element of same or like function.

The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining embodiments of the present invention, and it is not intended that restriction to embodiments of the present invention.

Refer to Fig. 1, the control method of embodiment of the present invention, it is used for controlling imaging device.Control method comprises the following steps:

S10: judge whether imaging device is in microshot pattern；

S20: when imaging device is in microshot pattern, controls imaging device and focuses to obtain focusing object distance；

S30: control imaging device to defocused repeatedly imaging measurement object distance when measuring each imaging under shutter trigger signal；And

S40: using described measurement object distance closest to the image of described focusing object distance as picture rich in detail.

Referring to Fig. 2, the control device 100 of embodiment of the present invention includes judge module 10, first and controls module the 20, second control module 30 and the first processing module 40.As an example, the control method of embodiment of the present invention can be realized by the control device 100 of embodiment of the present invention, and can be applicable to electronic installation 1000, and electronic installation 1000 can include controlling device 100 and imaging device 200.

Wherein, the step S10 of the control method of embodiment of the present invention can be realized by judge module 10, and step S20 can be controlled module 20 by first and realize, and step S30 can be controlled module 30 by second and realize, and step S40 can be realized by the first processing module 40.In other words, it is judged that module 10 is used for judging whether imaging device 200 is in microshot pattern.First controls module 20 for when imaging device 200 is in microshot pattern, controlling imaging device 200 and focus to obtain focusing object distance.Second controls module 30 for controlling imaging device 200 to defocused repeatedly imaging measurement object distance when measuring each imaging under shutter trigger signal.First processing module 40 is for measure object distance closest to the image of focusing object distance as picture rich in detail.

When using electronic installation 1000 to carry out shooting photo, running into the photographed scene in the less situation of object distance, that is to say microshot, microshot generally can shoot in closer distance and obtain the object image of bigger multiplying power.In such image, user is easier to observe the detail content of objects, for instance form and texture, increases the enjoyment of taking pictures of user.

Should be noted that, although be microshot, but the distance of imaging device 200 and object can not be excessively near, excessively near object distance will cause that imaging device 200 cannot be focused.

It is appreciated that; when user's hand-hold electronic device 1000 shoots; in choosing the process that object carrying out is focused; inevitably there is slight shake in hand, shooting distance farther out time, shake in flakes impact less; and the development along with the imaging device 200 being applied to electronic installation 1000; imaging device 200 would generally adopt certain stabilization measure, for instance optical anti-vibration or electronic flutter-proof so that imaging device 200 remains to shoot image clearly when shake.But under macro mode, shake is exaggerated too, therefore stabilization poor effect.

It is that imaging device 200 is focused after successfully owing to shake causes the unsharp main cause of imaging, rocking of object fore-and-aft direction, it is thus desirable to focusing motor is focused again, guarantee image is clear, and under macro mode, the less shake in front and back is accomplished by the adjustment that focusing motor is bigger, in this case, imaging device 200 is difficult to complete repeatedly to focus in once shooting.

The control method of embodiment of the present invention, when judging that imaging device 200 is in macro mode, controls imaging device 200 and focuses and obtain focusing object distance.Press shutter user and trigger repeatedly imaging after shutter signal, and measurement object distance when measuring each imaging respectively.Measurement object distance and imaging object distance are compared, and chooses and measure in object distance closest to the image of focusing object distance as the picture rich in detail under macro mode.

In sum, the control method of embodiment of the present invention, control device 100 and electronic installation 1000, when imaging device 200 is in microshot pattern, obtain multiple image when triggering shutter signal and carry out object distance and compare thus obtaining image clearly, being effectively improved the stabilization effect under microshot pattern.

In some embodiments, electronic installation 1000 can be the electric terminal that mobile phone or panel computer etc. have camera function.And imaging device 200 includes preposition and/or rearmounted camera.

It is appreciated that electronic installation 1000 includes but not limited to the example of present embodiment.

In some embodiments, focusing object distance is obtained by contrast focal modes, phase place focal modes and/or laser focal modes.

In some embodiments, imaging device 200 includes laser ranging system 210.

Measuring object distance to be obtained by laser ranging system 210, in other words, under triggering shutter signal during repeatedly imaging, each imaging all has laser ranging system 210 to obtain measurement object distance.

It should be noted that focus after successfully according to acquired focusing object distance, will no longer again promote focusing motor focus again, in other words, although owing to shake makes object distance change, but still adopting image distance when focusing successfully to carry out imaging, measure respectively when secondary measurement object distance when imaging.

Referring to Fig. 3, in some embodiments, imaging device 200 includes laser ranging system 210.

Control method includes step:

S00: control laser ranging system and launch laser to object；And

S01: process the laser of the return that laser ranging system receives to obtain the object distance of object.

Step S10 is by judging less than preset distance, whether object distance judges whether imaging device is in microshot pattern.

Refer to Fig. 4, in some embodiments, control device 100 and include the 3rd control module 50 and the second processing module 60.Step S00 can be controlled module 50 by the 3rd and realize, and step S01 can be realized by the second processing module 60.In other words, the 3rd controls module 50 and is used for controlling laser ranging system 210 and launches laser to object.And the second processing module 60 is used for the laser processing the return that laser ranging system 210 receives to obtain the object distance of object.Judge module 10 is for by judging less than preset distance, whether object distance judges whether imaging device 200 is in microshot pattern.

Such as the explanation of above-mentioned embodiment, the usual object distance of microshot pattern is less, for instance preset distance could be arranged to 30 centimetres, and in other words, when the object distance of object is less than 30 centimetres, imaging device 200 is in microshot pattern.

It is to be appreciated that the concrete numerical value of preset distance is only and schematically illustrates, the design parameter according to imaging device 200, for different imaging devices, the unlatching distance of its macro mode also differs.

Laser focal modes mainly utilizes the characteristic that infrared light centrality not easily spreads by force, emit from laser ranging system by recording infrared light, reflect through target surface, the time difference finally received, image-signal processor calculate the target distance to imaging device.This distance is the object distance in focus process, and the focometer further according to eyeglass module calculates the concrete numerical value of the required image distance adjusted and then adjusts focusing position, it is achieved focusing.Thus, laser focal modes can the object distance of quick obtaining object.

It is understandable that, explanation such as above-mentioned embodiment, focusing object distance can also pass through contrast focal modes except laser focal modes or phase place focal modes obtains, thus likely, it is judged that whether imaging device 200 is in microshot pattern can be undertaken by contrast focal modes or phase place focal modes.Comparatively speaking, laser focal modes obtains the process of focusing object distance the most directly, quickly and accurately by laser ranging system 210.

So, available laser ranging system 210 quick and precisely obtains the object distance of object, thus judging whether imaging device 200 is in microshot pattern, in order to the stabilization carrying out image under microshot pattern processes, and obtains the picture rich in detail under microshot pattern.

Referring to Fig. 5, in some embodiments, imaging device 200 still includes laser ranging system 210.

Part different from the embodiment described above is in that, control method includes step after step S00:

S02: recording laser range unit is by launching laser to receiving the time that laser returns.

Step S10 is by judging less than the scheduled time, whether the time judges whether imaging device is in microshot pattern.

Refer to Fig. 6, in some embodiments, control device 100 and include the 4th control module 70 and the 3rd processing module 80.Step S00 can be controlled module 70 by the 4th and realize, and step S02 can be realized by the 3rd processing module 80.In other words, the 4th controls module 70 and is used for controlling laser ranging system 210 and launches laser to object.And the 3rd processing module 80 is extremely received, by launching laser, the time that laser returns for recording laser range unit 210.Judge module 10 is for by judging less than the scheduled time, whether the time judges whether imaging device 200 is in microshot pattern.

Essentially identical with above-mentioned embodiment principle, it is different in that, present embodiment is by comparing the time but not object distance judges whether imaging device is in microshot pattern.

So, can be judged whether imaging device 200 is in microshot pattern according to laser ranging system 210 by the time launched to receiving range laser, in order to the stabilization carrying out image under microshot pattern processes, and obtains the picture rich in detail under microshot pattern.

In some embodiments, step S30 includes:

Step S31: compare measurement object distance and focusing object distance and to measure the image differing minimum in object distance with focusing object distance for described picture rich in detail.

In some embodiments, step S31 can be realized by processing module 30.

It is appreciated that, after focusing completes, such as complete defocused by laser focal modes, the focusing object distance U of object can be obtained, user presses shutter key, owing to hand is shaken, it is possible to the object distance that can cause multiple images obtained within the unit interval is different, recording measurement object distance respectively is U1, U2, U3 ... Un, wherein n is positive integer.Un can more than or less than focusing object distance.Un and U is compared, chooses | Un-U | minimum, namely measurement object distance immediate with focusing object distance U.And using image corresponding to this measurement object distance thus as the picture rich in detail under microshot pattern.

So, the focusing object distance when measurement object distance measured when triggering a shutter signal repeatedly imaging by comparing and focusing compares, and wherein differs the minimum image corresponding to measurement object distance with focusing object distance and is picture rich in detail.

It is appreciated that, focusing after successfully, imaging device is by according to object distance when focusing successfully, and controlling the image that imaging lens obtains in relevant position is image clearly, and owing to hand shake causes the actual object distance of image during imaging more than or less than focusing object distance, what therefore shoot is not fogging clear.And get over hour when the object distance of image differ with focusing object distance, image is also more clear, and thus, measurement object distance during by comparison each imaging and focusing object distance, namely the image wherein differing minimum is picture rich in detail.
