Here, the preset split-screen multitasking instruction specifically refers to split-screen display of images captured by the first camera and the second camera. That is to say, the split-screen object for split-screen display is carried in the preset split-screen multitasking instruction. In this step, the split-screen objects are images captured by the first camera and the second camera.

In addition, the input method of the preset split-screen multitasking command can be provided by setting a virtual button or a preset gesture on the camera preview interface for the user to input.

Here, the image preview interface is a photo preview interface, including: a first split-screen display area and a second split-screen display area.

Specifically, the first image and the second image may be correspondingly displayed in the split-screen display area of the image preview interface according to the preset corresponding relationship between the split-screen display area and the image captured by the camera.

In this step, by displaying the first image captured by the first camera and the second image captured by the second camera in split screens on the image preview interface, it is convenient for the user to observe the images captured by the first camera and the second camera synchronously, and can be used as a follow-up adjustment for the second image. An important basis for the first image and the second image.

Step 102, when both the first image and the second image contain images of people, adjust the first image and/or the second image so that the people in the first image in the image preview interface The difference between the size of the image and the size of the character image in the second image is within a preset range; wherein, the first camera is one of a front camera and a rear camera, and the second camera is Another one of the front camera and rear camera.

Here, it may be identified whether the first image and the second image contain images of people through face recognition technology.

Here, the preset range specifically refers to a numerical range in which the sizes of the person images in the first image and the second image in the image preview interface are approximately equal.

It should be noted that the purpose of adjusting the first image and/or the second image so that the size difference between the first image and the character image in the second image in the image preview interface is within a preset range is to make the image The images in the preview interface are more harmonious to further improve the imaging effect of the photographed images.

In the embodiment of the present invention, when it is detected that the first camera and the second camera of the mobile terminal start capturing images at the same time, the first image captured by the first camera and the second image captured by the second camera are separated on the image preview interface. screen display, and when both the first image and the second image contain person images, adjust the first image and/or the second image so that the size difference of the person images in the two images in the image preview interface is within a preset value. In this way, not only can the images captured by the first camera and the second camera of the mobile terminal be observed synchronously, but also the size of the person images in the images captured by the first camera and the second camera can be adjusted, so that the image preview interface The image screen is more harmonious, which improves the imaging effect of the photographed image and improves the user's photographing experience.

Based on the embodiment described in FIG. 1, as a preferred implementation, step 102 includes:

adjusting the focal length of the first camera and/or the second camera so that the size of the person image in the first image in the image preview interface is equal to the size of the person image in the second image of the person image .

Specifically, this step may include:

Acquiring the size of the person image in the first image and the size of the person image in the second image; judging whether the difference between the size of the person image in the first image and the size of the person image in the second image is greater than a preset threshold; If so, adjust the focal length of the first camera and/or the second camera so that the size of the character image in the first image in the image preview interface is the same as the size of the character image in the second image of the character image The size difference is within a preset range.

It should be noted that if the size of the person image in the first image is larger than the size of the person image in the second image and exceeds a preset threshold, the focal length of the second camera is adjusted so that the image preview interface The difference between the size of the character image in the first image and the size of the character image in the second image of the character image is within a preset range;

If the size of the character image in the second image is greater than the size of the character image in the first image, and exceeds the preset threshold, the focal length of the first camera is adjusted so that the first image in the image preview interface The difference between the size of the person image and the size of the person image in the second image of the person image is within a preset range;

That is to say, the adjustment of the focal length of the camera is specifically the adjustment of the focal length of the camera corresponding to the image with a larger size of the person image among the first image and the second image satisfying the above determination condition.

In the above implementation steps, the process of human-computer interaction is omitted, and the purpose of quickly adjusting the first image and the second image in the image preview interface can be achieved by automatically adjusting the focal length of the first camera and the second camera, so that the image preview interface The difference between the size of the person image in the first image and the size of the person image in the second image is within a preset range.

Adjust the zoom factor of the first image and/or the second image so that the size of the character image in the first image in the image preview interface is the same as the size of the character image in the second image of the character image The difference in size is within a preset range.

Specifically, this step may include the following preferred implementation methods:

Way 1: When the first camera and the second camera are both fixed in focus and have the same focal length, according to the received user's first selection operation on the first image or the second image on the image preview interface, Determine the size of the image corresponding to the first selection operation as a reference size; enlarge or reduce the size of the image not corresponding to the first selection operation to the reference size, so that the character image in the first image The size of is equal to the size of the character image in the second image of the character image.

Here, the first selection operation includes a preset gesture operation on the first image or the second image. Specifically, it is a preset gesture operation on the split-screen display area where the first image is located or the split-screen display area where the second image is located.

Specifically, the preset gesture operations include: click, long press, drag, double click, slide, zoom, and the like.

Preferably, the preset gesture operation is a zoom operation on the image preview interface.

Here, the zooming operation includes: shrinking operation (two or more fingers touch the touch screen, then bring the fingers together) and stretching operation ((two or more fingers touch the touch screen, then separate the fingers); Among them, the shrinking operation is used to reduce the size of the image, and the stretching operation is used to enlarge the size of the image.

Specifically, when the preset gesture operation is a zoom operation on the image preview interface, if it is recognized that the zoom operation is a stretch operation, and the operation position of the image preview interface corresponding to the stretch operation is identified, the corresponding image is determined; if is the first image, then determine that the size of the first image is the reference size; then, enlarge the size of the second image to the reference size, so that the size of the character image in the first image in the image preview interface is the same as The size of the person images in the second image is equal.

Of course, according to the received user's first selection operation on the first image or the second image on the image preview interface, the size of the image corresponding to the first selection operation can be enlarged or reduced to a size that does not match the selected image. The size of the image corresponding to the first selection operation is adjusted so that the size of the character image in the first image in the image preview interface is equal to the size of the character image in the second image.

Method 2: When the first camera and the second camera are both fixed in focus and have the same focal length, enlarge or reduce the size of the first image and the second image to the same preset size, so that all The size of the character image in the first image in the image preview interface is equal to the size of the character image in the second image of the character image.

In this step, the process of human-computer interaction is omitted, and the purpose of quickly adjusting the first image and the second image in the image preview interface can be achieved by automatically adjusting the image size of the first camera and the second camera, so that the image preview interface The size of the person image in the first image is equal to the size of the person image in the second image.

Specifically, this step may include:

According to the received user's second selection operation on the first image or the second image on the image preview interface, determine the image corresponding to the second selection operation as the background image in image synthesis;

It should be noted that the second selection operation includes a preset gesture operation on the first image or the second image. Specifically, it is a preset gesture operation on the split-screen display area where the first image is located or the split-screen display area where the second image is located.

Specifically, the preset gesture operations include: click, long press, drag, double click, slide, zoom, and the like.

Specifically, when the preset gesture operation is a double-click operation on the image preview interface, the corresponding image is determined by identifying the double-click position on the screen of the image preview interface corresponding to the double-click operation; if it is the first image, then determine the first image as The background image in the image synthesis, correspondingly, the second image is used as the non-background image in the image synthesis; if it is the second image, then determine the second image as the background image in the image synthesis, and correspondingly, the first image is used as the image synthesis Non-background images in .

Here, the first image or the second image as the background image means that the entire image is used as the background image in image synthesis.

A person image in the non-background image is extracted and synthesized with the background image to obtain a target image, and the non-background image is an image not corresponding to the second selection operation.

Here, the person image in the non-background image can be extracted by the image contour extraction algorithm, and the non-background image can be extracted by comparing the non-background image with these standard templates through pre-stored standard templates with representative person contours images of people in .

Also, when the extracted character image in the non-background image is synthesized with the background image, the character image in the non-background image is synthesized according to the preset position information of the image to be added (that is, the character image in the non-background image) to the preset position of the background image.

Of course, the human-computer interaction can also be used to realize the synthesis of the person image in the extracted non-background image and the background image. That is, by dragging the person image in the non-background image, drag it to the target position, and synthesize it with the background image.

As another preferred implementation, step 103 may include:

Specifically, this step includes:

Determine the target image composition template according to the received user's third selection operation on different preset image composition templates;

Here, the preset image composition module includes preset image composition parameters. For example, the type of image synthesis (used to characterize the effect of image synthesis), the size of image synthesis, and the like.

In addition, the preset image synthesis template can be selected by the user through setting menu options, or can be selected by the user in the form of graphic display. There are many ways, which are not specifically limited here.

According to the target image synthesis template, image synthesis is performed on the adjusted first image and the second image to obtain a target image.

It should be noted that, by selecting a preset image composition template, different needs of different users for image composition effects can be met.

To sum up, the photographing method provided by the embodiment of the present invention combines the first image captured by the first camera and the second image captured by the second camera when the first camera and the second camera of the mobile terminal are detected to start capturing images at the same time. The two images are displayed in split screens on the image preview interface, and when both the first image and the second image contain person images, adjust the first image and/or the second image so that the size of the person images in the two images in the image preview interface The difference in size is within a preset range, so that not only can the images captured by the first camera and the second camera of the mobile terminal be observed synchronously, but also the size of the person image in the images captured by the first camera and the second camera can be adjusted, In order to make the image picture in the image preview interface more harmonious, improve the imaging effect of the photographed image, and enhance the user's photographing experience.
