Two cameras, such as a first camera and a second camera, can be arranged on the electronic device 100, and then detection of a backlight scene is realized through the two cameras so as to perform automatic switching of a backlight mode. In addition, the electronic device 100 may further include a plurality of cameras, such as a first camera and a plurality of second cameras, and set the overexposure parameters with different sizes for the plurality of second cameras to switch to the optimal backlight mode. Two cases are described below:
first, a total of two cameras, namely a first camera and a second camera, are disposed on the electronic device 100.
Fig. 2 is a schematic flow chart of a backlight mode automatic switching method according to an embodiment of the present invention, where the method includes:
and step S110, controlling the first camera to acquire a first image, controlling the second camera to overexpose to acquire a second image, and displaying the first image on an application interface of the electronic equipment.
That is to say, after the user opens the cameras of the electronic device 100, the first camera and the second camera enter the preview mode, that is, the first camera starts to capture the first image, and the second camera captures the second image, it should be noted that, since the two cameras are arranged side by side on the side of the electronic device 100 opposite to the screen, the distance between the two cameras is small, so the picture contents captured by the two cameras are substantially the same, and only the edge part of the image is different due to the distance between the two cameras.
In addition, the first image acquired by the first camera is displayed on an application interface of the electronic device for a user to check, and the second image acquired by the second camera is used for detection of a backlight scene, so that the whole detection operation is performed at the background of the electronic device 100, the display effect of the first image is not influenced, and the user experience is not influenced.
It should be noted that the first camera is to capture an image in a normal state, that is, parameters of the first camera are not specifically set, and the first camera captures an image in an automatic exposure mode or a normal exposure mode, for example. The parameter of the second camera is preset to be overexposure, so that the parameter of the second camera is set to be overexposure, because if the current scene is a backlight scene, the image quality of the image collected by the first camera is not clear due to backlight, the second camera is equivalent to overexposure processing on the image collected under the backlight scene due to the fact that the parameter is set to be overexposure, and the finally obtained image is clearer than the image collected by the first camera. Therefore, whether the current scene is a backlight scene or not and whether the acquired image is a backlight image or not can be automatically detected by comparing the definition of the images acquired by the first camera and the second camera.
Step S120, receiving and responding to the selected operation of the user on the first image displayed on the application interface to determine the target area on the first image and the second image.
Specifically, when a user takes a picture, a first image displayed on an application interface is clicked to select a region in which the user is interested, the region in which the user is interested is a target region on the first image, and since the second image is consistent with the first image in content, a region in which the second image is consistent with the target region on the first image is a target region of the second image. Fig. 3 is a schematic flow chart illustrating the sub-steps of step S120 of the backlight mode automatic switching method according to the embodiment of the present invention, where the step S120 includes:
step S121, performing matching alignment on the first image and the second image.
Specifically, the first image and the second image are simply matched and aligned, that is, the same pixel points on the first image and the second image are matched and aligned one by one.
Step S122, responding to the selected operation of the user on the first image displayed on the application interface to determine the target area on the first image.
Specifically, when a user clicks a certain point on the first image on the application interface, a region having the same attribute as the point selected by the user on the first image displayed on the application interface is determined as a target region of the first image according to a preset algorithm. The attribute is, for example, the color of the pixel point. For example, when the user wants to capture a "table" in the first image, the user clicks any point on the "table", and the electronic device 100 determines an area having an approximate color and an approximate texture to the point, such as the entire "table", as a target area in the first image. It should be noted that, in the embodiment of the present invention, the preset algorithm is a flood filling algorithm, or another algorithm capable of implementing the extraction area.
Step S123, determining a region on the second image aligned with the target region on the first image as a target region of the second image.
That is, since the first image and the second image have been matched and aligned before, when the target region on the first image is determined, the region on the second image aligned with the target region on the first image is the target region of the second image.
Step S130, respectively determining a first sharpness value of the target region on the first image and a second sharpness value of the target region on the second image.
Specifically, a mature definition evaluation algorithm is adopted to respectively calculate a first definition value of a target area on a first image and a second definition value of the target area on a second image.
Step S140, if the second sharpness value is greater than the first sharpness value, the mode of the electronic device is switched to the backlight mode.
Specifically, if the second definition value is greater than the first definition value, it is indicated that the definition of the image acquired by the second camera is superior to that of the image acquired by the first camera, and since the parameter preset for the second camera is overexposure, it is proved that the current scene should be shot clearly by using the overexposure parameter, and then it is proved that the current scene is a backlight scene. That is to say, the first image collected by the first camera is too dark in the whole target area due to the existence of highlight, and the image quality is not clear, and the second camera performs overexposure processing on the collected second image, so as to obtain a clearer second image. Therefore, when the second definition value is larger than the first definition value and indicates that the current scene is a backlight scene, the mode of the electronic device 100 is automatically switched to the backlight mode to take a picture, so that the user experience is improved.
Secondly, a plurality of cameras, namely a first camera and a plurality of second cameras, are arranged on the electronic device 100, the second cameras set overexposure parameters of different sizes, and each second camera can acquire a second image. That is, the electronic device 100 acquires a first image and a plurality of second images, and the electronic device 100 analyzes the plurality of second images to detect whether the current scene is a backlight scene and determine a preferred backlight mode.
Specifically, because the plurality of second cameras have the overexposure parameters with different sizes, after the acquired second images are subjected to overexposure processing with different degrees by the different second cameras, the plurality of second images will show different definitions. Meanwhile, multiple backlight modes are stored in the electronic device 100, and each backlight mode also has different backlight shooting parameters, so that pictures shot in a backlight scene are clearer. The step of associating the backlight mode with the second camera having substantially the same image resolution, that is, if one of the second resolution values is larger than the first resolution value, switching the mode of the electronic device to the backlight mode, may include:
firstly, selecting a second camera target second camera with the largest second definition value of a target area of a second image acquired by all second cameras.
Furthermore, if the current scene is a backlight scene, the mode of the electronic device 100 is switched to the backlight mode corresponding to the target second camera.
Since the second definition values of the target areas on the second images are calculated, it is clear which second camera's overexposure parameter the second image is subjected to is processed, and then the mode of the electronic device 100 is switched to the backlight mode substantially consistent with the overexposure parameter of the second camera, so that the finally acquired image is clearer.
Therefore, the embodiment of the invention provides an automatic backlight mode switching method, which detects whether a current scene is a backlight scene through two or more cameras, and automatically switches the mode of the electronic device 100 to the backlight mode when the current scene is determined to be the backlight scene, so that the user experience is improved.

The embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by the processor 140, the method for automatically switching the backlight mode disclosed in the embodiment of the present invention is implemented.
