Step 101, if a shooting function activation instruction is received, start the front camera and the rear camera to collect images.

In this embodiment, the mobile terminal has two oppositely arranged display screens: a first display screen and a second display screen, wherein the first display screen is a front display screen, and the second display screen is a rear display screen, and, in A front camera is set on the same side as the first display screen, and a rear camera is set on the same side as the second display screen. Therefore, in this step, the front camera and the rear camera will be turned on to collect images after it is determined that the start command of the shooting function is received.

Step 102, displaying the preview image captured by the front camera on the second display screen, and displaying the preview image captured by the rear camera on the first display screen.

In this step, the preview image collected after the camera is turned on in step 101 is displayed on a display screen that is not on the same side as the camera, the preview image collected by the front camera is displayed on the second display screen, and the preview image collected by the rear camera is displayed on the second display screen. The preview image is displayed on the first display screen, so that both the shooting user and the photographed user can view each other's picture from the display screens facing themselves.

Step 103, if a shooting instruction is received, control the rear camera to perform a shooting operation.

In this step, after the shooting party and the photographed party complete shooting preparations by viewing each other's screens and trigger a shooting instruction, the mobile terminal will receive the shooting instruction, control the rear camera to perform shooting operations, and complete the shooting.

Through the above steps 101-103, the mobile terminal will display the preview images collected by each camera on the display screen on the other side after receiving the shooting function start instruction through the cameras arranged on different sides, so that the shooting side The party and the subject can avoid the occlusion of the mobile terminal, and view the preview screen of the other party from the display screen facing themselves, so as to guide the party to shoot, grasp the timing of the capture in time, and capture high-quality images.

For example, user A (shooter) of the mobile terminal is the mother of party B (child) to be photographed. After user A turns on the camera and starts the camera, he triggers the command to start the shooting function, turns on the front camera and the rear camera to collect images, and the rear camera Toward the subject B, the preview image of the subject B captured by the rear camera will be displayed on the front display screen 201 (first display screen) facing the user A, as shown in FIG. 2 . At this time, the preview image captured by the front camera facing user A will be displayed on the rear display screen 301 (second display screen) facing the subject B, as shown in FIG. 3 . For children who are inattentive or nervous, user A can use some facial expressions or gestures to collect and display on the rear display screen through the front camera to guide the subject B to take pictures. View in real time on the front display, trigger the shooting command at the wonderful moment of the subject B, and capture high-quality images. Of course, if the camera facing the subject B is the front camera, and the camera facing the user A is the rear camera, the front camera can also be controlled to perform the shooting operation according to the shooting instruction. However, generally speaking, it is preferred that the mobile terminal The image of the subject is displayed on the main screen (front screen) of the .

Wherein, after the camera is turned on, when the user wants to shoot the current image by using the mobile terminal, a shooting instruction can be input through a preset trigger mode. The shooting instruction described here may be triggered by a physical button or a virtual button, or by biometric technology, such as voice, touch, infrared, gesture, etc. Taking physical button triggering as an example, a single physical button can be used for triggering, or a combination of multiple physical buttons can be used for triggering. For example: when using the gesture trigger mode, when a preset gesture shooting (such as "three or four fingers slide a certain distance on the display screen") is detected, the shooting command triggered by the user operation or the shooting button is pressed, Determine the triggering shooting order. Or input voices such as "photograph" and "eggplant", and the mobile terminal receives and recognizes the voice shooting instruction. Therefore, in the embodiment of the present invention, before step 103 and after step 102, it also includes:

If the voice information including the preset keyword is detected, it is determined that the shooting instruction is received;

Alternatively, if an air gesture matching a pre-stored shooting trigger gesture is detected, it is determined that a shooting instruction is received;

Alternatively, if an expression matching the pre-stored shooting triggering expression is detected, it is determined that the shooting instruction is received.

Here, by detecting the corresponding object corresponding to the preset trigger mode: voice information including preset keywords, an air gesture matching a pre-stored shooting trigger gesture or an expression matching a pre-stored shooting trigger expression, to Reception of the photographing instruction is confirmed. Specifically, the voice pickup of the mobile terminal can be used to collect the user's voice, and it is judged whether there is voice information of preset keywords in the voice, and if there is, it is determined that a shooting instruction has been received; or, through the front camera and/or rear camera The image collection of the camera detects whether the user's gesture in the air matches the pre-stored shooting trigger gesture, and if it matches, it is determined that the shooting instruction is received; or, through the image collection of the front camera and/or rear camera, detect the user's Whether the facial expression matches the pre-stored shooting trigger facial expression, and if it matches, it is determined that the shooting instruction is received.

Wherein, step 102 includes:

displaying the preview image collected by the front camera on the second display screen in full screen;

displaying the preview image captured by the rear camera on the first display screen in full screen.

Here, by displaying the preview image collected by the front camera on the second display screen in full screen, and displaying the preview image collected by the rear camera on the first display screen in full screen, it is possible to ensure that the shooting party and the photographed party located on both sides of the mobile terminal Both can view the other party's preview image more clearly, so as to obtain a better captured image.

Or, as shown in Figure 4, step 102 includes:

Step 1021a, displaying the preview image captured by the front camera on the second display screen in full screen.

In this step, considering that the subject does not need to know his own preview image, in order to ensure the shooting guidance effect of the shooter, the preview image of the front camera that captures the shooter's image will be displayed in full screen on the second display screen.

Step 1022a, dividing the display area of the first display screen into a first display area and a second display area.

In this step, in order to enable the photographer to grasp his own preview image in time while observing the preview image of the photographed party, the mobile terminal will divide the display area of the first display screen facing the photographer into the first display area and the second display area. display area to realize the same screen display of two preview images.

Step 1023a, displaying the preview image captured by the front camera and the preview image captured by the rear camera in the first display area and the second display area respectively.

In this step, after the display area of the first display screen is divided into a first display area and a second display area in step 1022a, the preview image collected by the front camera and the preview image collected by the rear camera can be displayed on the In the first display area and the second display area, it is convenient for the photographer to observe the preview images on both sides at the same time.

In this way, according to the above steps 1021a-1023a, the photographed party will clearly see the preview image of the photographed party, and the first display screen obtains the first display area and the second display area by splitting the screen, so that the photographed party will be able to move towards his own In the first display screen, the preview images on both sides can be viewed on the same screen, and the expressions and actions can be adjusted in real time, so as to realize more effective shooting guidance for the subject and obtain the desired image. Wherein, if the preview image collected by the front camera is displayed in the first display area, the preview image collected by the rear camera will be displayed in the second display area; if the preview image collected by the front camera is displayed in the second display area, then The preview image captured by the rear camera will be displayed in the first display area.

Continuing the above-mentioned example of user A shooting subject B, since the preview image of subject B will be displayed on the front display screen (first display screen) facing user A, as shown in FIG. 5a, the Two display areas will be divided on the front display screen: the first display area 501 and the second display area 502, so that when the preview image of the subject B captured by the rear camera is displayed on the front display screen, the The preview image of user A captured by the front camera is displayed on the front display screen, and user A checks and adjusts his facial expressions in real time, so as to realize more effective shooting guidance for the subject being photographed. Of course, as shown in FIG. 5 b , the positions of the first display area 501 and the second display area 502 can also be exchanged.

Often the mobile terminal will pre-set the positions of the first display area and the second display area on the first display screen. However, for the fixed first display area and the second display area, when the objective lens is far away, the rear camera Due to the limitation of the area size in the corresponding display area, the collected image may not be clearly displayed, which will affect the final acquisition of the image. Therefore, on the basis of the above embodiment, after step 1022a, it also includes:

detecting an adjustment operation to any one of the first display area and the second display area;

If an adjustment operation is detected, adjusting display parameters of the first display area and/or the second display area according to the adjustment operation;
