In order to illustrate technical solution described herein, the following is a description of specific embodiments.

Fig. 1 is a kind of implementation process schematic diagram of the control method of multi-camera system provided by the embodiments of the present application, such as This method shown in scheming may comprise steps of:

Step S101 is obtained in the multi-camera system when receiving preset instructions according to current photo environment The acquisition parameters of first camera.

It in the embodiment of the present application, include at least two cameras in the multi-camera system, it can be by multi-cam One or more of system is known as the first camera.The preset instructions can be the pre-set instruction taken pictures, The instruction that can also be preset time interval triggering, can also be other instructions certainly, herein with no restrictions, the default finger Order can trigger the acquisition parameters that the first camera in the multi-camera system is obtained according to current photo environment.

As an example, user can be used as default finger by the instruction that the physical button taken pictures corresponding on mobile terminal issues It enables, the acquisition parameters for obtaining the first camera in the multi-camera system according to current photo environment can be triggered；May be used also To be, the shooting of the first camera in the multi-camera system is obtained according to current photo environment at interval of triggering in 3 seconds Parameter is provided with timer on the mobile terminal where the multi-camera system, and the timing time of timer was 3 seconds, 6 Second ... it triggers at 3n seconds and is joined according to the shooting that current photo environment obtains the first camera in the multi-camera system Number, the integer that wherein n is >=1.

The acquisition parameters include: time for exposure and/or f-number；

Correspondingly, the current photo environment of the basis obtains the shooting ginseng of the first camera in the multi-camera system Number includes:

The light exposure of the first camera under automatic mode is determined according to the light intensity of current photo environment；

Based on current exposure mode, when obtaining the exposure of the first camera according to the light exposure of the first determining camera Between and/or f-number.

In the embodiment of the present application, the free schema indicates that some acquisition parameters are adjusted by equipment itself in exposure process Section, it is manually adjusted without user, which can preset, such as the parameters such as aperture, aperture time.Camera is clapped The quality for the photo taken the photograph is related with light exposure, popular understanding, is exactly the clarity of image and sensor experience how many Light is related, and light exposure is exactly to measure an index of the light that sensor receives, and the light that sensor receives is very big It is related with the light intensity of photo environment in degree.Automatic photometric system, automatic photometric system can be set on mobile terminals The numerical value of measurement can be used as the light intensity of photo environment.So the application can be measured currently by automatic photometric system Then the light intensity of photo environment determines the light exposure of the first camera according to the light intensity of current photo environment, for example, When light intensity is A, being correspondingly arranged light exposure is a, and when light intensity is B, being correspondingly arranged light exposure is b etc..

After the light exposure that the first camera has been determined, it is necessary to time for exposure and/or light by the first camera Circle value adjusts the light exposure of the first camera.In practical applications, light exposure can be adjusted by the time for exposure, can also passed through Aperture adjusts light exposure, and adjusting light exposure by the time for exposure is adjusted by the speed of shutter, is adjusted and is exposed by aperture Amount is adjusted by the size of aperture.If light exposure be it is certain, when the speed of shutter is fast, aperture will be larger, fastly When the speed of door is slow, aperture is with regard to smaller.The combination of aperture and shutter is formed light exposure, in the certain situation of light exposure Under, this combination is not unique.However, different combinations will be obtained based on different exposure modes.Exposure mode can be with It include: that shutter speed centainly changes aperture, aperture centainly changes shutter speed, it is also possible to which the two changes；As an example, true Determine to obtain corresponding light exposure by changing f-number in the case where the speed of shutter；It is most at present there are also a kind of situation The aperture of camera in mobile phone can not change, and indicate that f-number can not change, it is necessary to change the speed of shutter, Namely the change time for exposure obtains corresponding light exposure.In practical application, aperture size is indicated by f value, institute Aperture size is indicated with f-number with us.

As the another embodiment of the application, the acquisition parameters further include: brightness gain values；

Correspondingly, the current photo environment of the basis obtains the shooting ginseng of the first camera in the multi-camera system Number further include:

The first camera shooting is obtained according to the time for exposure of the light intensity of current photo environment and the first camera of determination The brightness gain values of head.

In the embodiment of the present application, luminance gain indicates charge-coupled device (charge coupled in camera Device, CCD) or complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) the photosensitive speed of photosensitive element.The namely speed of the sensor photosensitive of camera.For the mobile end that aperture is fixed For end, time for exposure and luminance gain are also that needs are mutually coordinated.In practical application, the time for exposure can be preferentially adjusted, Under the premise of not overexposure, the increase time for exposure can increase signal-to-noise ratio, make image clearly.Certainly, it takes pictures light is very weak Under environment, the time for exposure can not infinitely increase, because as the increase noise of time for exposure can also accumulate, or shooting movement Object when wish that the speed of shutter is quicker.Luminance gain is typically just weak in light, but is not desired to increase the feelings of time for exposure It is used under condition, general luminance gain all generates very big noise.In different brightness gain values, the image quality of image is different, Brightness gain values are smaller, and noise is smaller；Brightness gain values are bigger, and noise is more.The ISO of digital camera is also the embodiment of the present application The luminance gain of middle meaning increases ISO value, is the sensitivity for increasing sensor devices to light.High sensitivity is sensitive to low illumination, together When it is also sensitive to noise signal, signal-to-noise ratio is small, thus high sensitivity generate image noise it is also more.

Popular understanding, adjusting brightness gain values is exactly to change ISO value, changes the photosensitive property of sensor devices, but meeting Influence image quality.Adjusting the time for exposure is then to change shutter speed, and not changing ISO value will not influence image quality.According to above Analysis, it can be deduced that if desired adjust the brightness gain values of the first camera, then the brightness gain values of the first camera can be with It is obtained by the time for exposure of the first camera of the light intensity and determination of current photo environment.

The time for exposure of first camera of the light intensity and determination of the current photo environment of basis obtains first The brightness gain values of camera include:

The light intensity corresponding theoretical time for exposure for calculating current photo environment, according to the theoretical time for exposure and institute The difference for stating the time for exposure of the first camera determines the brightness gain values of first camera.

In the embodiment of the present application, as previously mentioned, the time for exposure cannot be unlimited increase, so, can not in the time for exposure In the case where continuing growing, adjustable brightness gain values are managed for example, can be calculated by the light intensity of current photo environment By the time for exposure, then the difference of the time for exposure of theoretical time for exposure and the first camera obtained is calculated, the first camera The reason of difference of time for exposure and theoretical time for exposure is exactly that unconfined cannot increase the time for exposure, finally according to the difference Value can determine the brightness gain values of first camera.

In practical application, the acquisition parameters of the first camera can also include other acquisition parameters, for example, focal length, backlight Compensation, white balance, signal-to-noise ratio etc., herein a different citing.
