Secondary camera is respectively used to export the image of photographed scene in shooting operation, and the secondary camera is additionally operable in shooting operation
Obtain the depth of view information of photographed scene.
In one embodiment, the secondary camera can be used for coordinating the main camera to be precisely calculated current bat
Take the photograph the depth of view information of scene.For example, the main camera and secondary camera difference output image, the secondary camera can be based on two
The depth of view information of the definition COMPREHENSIVE CALCULATING photographed scene of object in the image that person exports respectively.
In another embodiment, the secondary camera can be used for output image, and according to the thing in the image of its output
The depth of view information of the sharpness computation photographed scene of body.
It is appreciated that the terminal can also calculate the depth of view information of photographed scene using other modes, due to calculating
Depth of view information is not the emphasis of technical solution of the present invention, repeats no more it here and realizes details.
As shown in figure 1, the control method of the camera may comprise steps of：
Step 101, when the main camera and the secondary camera are in focusing state, current photographed scene is monitored
Whether changed relative to the scene in the output image of the last shooting operation.
Wherein, output image of the present invention refers to that the main camera and/or the secondary camera directly collect
Image, be not image after treatment.The terminal can be based on the depth of view information associated with the output image to described
Output image carries out background blurring processing, to obtain background blurring image.Because background blurring processing is not the technology of the present invention side
The emphasis of case, it is repeated no more here and realizes details.
Step 102, if monitoring, current photographed scene does not change, closes the secondary camera.
If it is appreciated that monitor that photographed scene does not change substantially in a short time, with the last bat
The depth of view information for taking the photograph the output image association of operation is exactly the depth of view information of current photographed scene, therefore is not necessarily to count again
The depth of view information of current photographed scene, the image output of the secondary camera temporarily can be first closed, to save background void
The power consumption of change.
It is understood that in one embodiment, in above-mentioned steps 102, monitoring that current photographed scene do not send out
After changing and close before the secondary camera, can also comprise the following steps：Then obtain and associated with the output image
Depth of view information.If that is, monitoring that current photographed scene does not change, acquisition associates with the output image
Depth of view information, then perform again close the secondary camera the step of.In order to perform the background blurring function of the terminal.
The control method of camera provided by the invention, the change of current photographed scene, and root can be monitored in real time in shooting process
The image that secondary camera is dynamically closed according to the change of photographed scene exports, to reduce in the process using background blurring function
In power consumption, and lift user experience.
Fig. 2 is the flow chart of the control method for the camera that second embodiment of the invention provides.Second embodiment
The main distinction of the control method of camera and the control method of the camera of first embodiment is, second embodiment
The step of also including obtaining the depth of view information associated with output image in the control method of camera and taken the photograph in the closing pair
The step of as after head.It should be noted that in the range of the spirit or essential attributes of the embodiment of the present invention, suitable for first
Each concrete scheme in embodiment can also repeat accordingly suitable for second embodiment to save space and avoiding
See, just repeat no more herein.

Fig. 3 is the step 101 shown in Fig. 1 and the step 201 shown in Fig. 2, " the current shooting of monitoring described in 204
Whether scene changes relative to the scene in the output image of the last shooting operation " refined flow chart.Such as Fig. 3 institutes
Show, whether the current photographed scene of the monitoring changes relative to the scene in the output image of the last shooting operation
Specifically include：
Step 301, the preview image of current photographed scene and the output image of the last shooting operation are obtained.
Step 302, the similarity of the preview image and the output image is calculated.
In one embodiment, calculating the preview image and the similarity of the output image includes：Described in calculating
Preview image and the overall similarity of the output image, i.e. judge whether scene integrally changes.
In another embodiment, calculating the preview image and the similarity of the output image includes：Calculate institute
State the similarity of the background parts of preview image and the background parts of the output image, i.e. judging the background parts of scene is
It is no to change.Due to calculating depth of view information primarily to doing background blurring, if background is constant, scape need not be calculated again
Deeply convince breath, therefore only can judge whether background parts change.
Step 303, judge whether the preview image and the similarity of the output image reach predetermined threshold value.Described
When preview image and the similarity of the output image reach predetermined threshold value, step 304 is performed；The preview image with it is described
The similarity of output image be less than or not up to predetermined threshold value when, perform step 305.
Step 304, judge current photographed scene relative to the scene in the output image of the last shooting operation not
Change.
Step 305, judge that current photographed scene is sent out relative to the scene in the output image of the last shooting operation
Changing.
