Camera.
It referring to figure 2., is a kind of flow diagram of backlight automatic mode switching method provided in an embodiment of the present invention, it should
Method includes：
Step S110 controls first camera and acquires the first image, controls the second camera overexposure acquisition the
Two images, and the first image is shown in the application interface of the electronic equipment.
I other words first camera and second camera will enter in advance after the camera of user's opening electronic equipment 100
Look at mode, i.e., first camera starts to acquire the first image, and second camera acquires the second image, it should be noted that by
It is the side being arranged side by side in electronic equipment 100 relative to screen in two cameras, therefore the spacing of two cameras is smaller, because
And the image content of two cameras acquisition is roughly the same, only image border partially due to two cameras itself are arranged between
Exist away from reason different.
In addition, the application interface that the first image that the first camera acquires is shown in electronic equipment is checked for user, the
Second image of two cameras acquisition will act as the detection of backlight scene, so that entire detection operation is after electronic equipment 100
Platform carries out, and has no effect on the bandwagon effect of the first image, will not influence user experience.
It should be noted that the first camera shooting is the image under acquisition normal condition, also i other words not to the first camera
Parameter be especially arranged, first camera according to auto exposure mode or normal exposure mode etc. according to for example adopting
Collection.The parameter of the second camera is preset as overexposure, why by the parameter of second camera overexposure is set, if being because working as
Preceding scene is backlight scene, then the image that the first camera acquires is since backlight meeting image quality is unintelligible, and second camera is due to setting
Setting parameter is overexposure, then it, which is equivalent to, has carried out overexposure processing to the image acquired under backlight scene, the figure finally obtained
As the image that will be acquired than the first camera is more clear.It can be seen that passing through the first camera of comparison and second camera
The clarity of the image of acquisition can detect whether current scene is backlight scene automatically, and whether the image of acquisition is backlight image.
Step S120, receives and responds user and determine institute to the selected operation of the first image shown on application interface
State the target area on the first image and the second image.
Specifically, will click the first image shown on application interface to choose use when user takes pictures
The interested region in family, the interested region of the user is the target area on the first image, due to the second image and first
Picture material is consistent, then is the target area of the second image with the consistent region in target area on the first image on the second image
Domain.Referring to figure 3., be a kind of backlight automatic mode switching method provided in an embodiment of the present invention step S120 sub-step
Flow diagram, step S120 include：

I other words since the first image and the second image have been done matching alignment before, then when the first figure has been determined
Behind upper target area, the region being aligned on the second image with the target area on the first image is the target of the second image
Region.
Step S130, respectively determine the first image on target area the first definition values and second figure
As the second definition values of upper target area.
Specifically, calculating separately the first clear of the target area on the first image using mature clarity evaluation algorithms
Second definition values of angle value and the target area on the second image.
Step S140 cuts the mode of the electronic equipment if second definition values are greater than the first definition values
It is changed to backlight mode.
Specifically, showing the clear of the image of second camera acquisition if the second definition values are greater than the first definition values
For clear degree better than the clarity of the image of the first camera acquisition, the parameter due to having preset second camera is overexposure, then proves
Current scene should be relatively clear using the parameter shooting of overexposure, and then proves that current scene is backlight scene.I other words first
First image of camera acquisition is due to the presence of bloom, so that target area is integrally excessively dark, image quality is unclear, and the second camera shooting
Head has carried out overexposure processing to the second image of acquisition, and then has obtained the second relatively clear image.As a result, when second is clear
Angle value is greater than the first definition values, shows current scene the mode of electronic equipment 100 to be automatically switched to inverse after backlight scene
Optical mode is taken pictures, to improve user experience.
Second, multiple cameras, i.e. first camera and multiple second camera shootings are provided on the electronic equipment 100
Head, multiple second camera are provided with different size of overexposure parameter, and each second camera can acquire second figure
Picture.Also i other words, which acquires altogether first image and several second images, the electronic equipment 100
It will carry out whether analysis detection current scene is backlight scene to several second images, and determine more preferably backlight mode.
Specifically, since multiple second cameras have different size of overexposure parameter, then different second camera pair
After second image of acquisition carries out different degrees of overexposure processing, different clarity will be presented in several second images.Meanwhile
It is also stored a variety of backlight modes in the electronic equipment 100, also there is every kind of backlight mode different backlight to take pictures parameter, so that
The picture shot under backlight scene is more clear.Thus by obtained image definition second camera unanimous on the whole and
Backlight mode is associated, i other words, " second definition values are greater than the first definition values if it exists, then by institute for this
State electronic equipment pattern switching be backlight mode " the step of may include：
Firstly, the second definition values for choosing the target area of the second image of all second cameras acquisition maximum the
Two camera target second cameras.
It in turn, is target second camera pair by the pattern switching of electronic equipment 100 if current scene is backlight scene
The backlight mode answered.
Due to calculating the second definition values of target area on each second image, so that specifying that the second image passes through
Be more clear after the overexposure parameter processing of which second camera, so by the pattern switching of electronic equipment 100 to this second
The overexposure parameter of camera backlight mode unanimous on the whole, so that the image finally acquired is more clear.
