Problems solved by technology

At this time, there is an overlapping area of ​​field of view between the large FOV camera and the small FOV camera. This overlapping area is the optically variable area after zooming. Therefore, the light-changing area is not located in the center of the large FOV image. The farther the shooting target is, the more the light-changing area tends to the center of the large FOV image. The closer the shooting target is, the farther the overlapping area is from the center of the large FOV image. After finding and locking the shooting target through the large FOV image in the preview mode, it is easy to lose the shooting target or the composition shifts when zooming in. It is extremely inconvenient to find the shooting target or recompose the picture after zooming in and zooming in

Embodiment 1

[0035] Such as figure 1 As shown, a multi-camera shooting method includes:

[0036] Start the large FOV camera and the small FOV camera in preview mode to obtain large FOV images and small FOV images respectively;

[0037] Calculate the light change area between the large FOV image and the small FOV image;

[0038] Display the large FOV image on the display as a preview image, and mark the optically variable area on the large FOV image;

[0039] Obtain the touch operation of the touch screen;

[0040] If the acquired touch operation is the preset first light-changing operation, switch to the first light-changing mode, and if the acquired touch operation is the preset second light-changing operation, then switch to the second light-changing mode, wherein, In the first optical change mode, the preview image is a large FOV image marked with an optical change area, and the output image is an optical change image. In the second optical change mode, the preview image is a large F...

Embodiment 2

[0062] Such as figure 2 As shown, a multi-camera shooting terminal includes a processor, a memory electrically connected to the processor, and a plurality of cameras coplanarly arranged, and a computer program for the processor to execute is stored in the memory When the processor executes the computer program, the multi-camera shooting method described in the first embodiment is performed.

[0063] Of course, the multi-camera shooting terminal also includes a display screen and a touch screen electrically connected to the processor, and the touch screen is arranged on the display surface of the display.

[0064] Preferably, the field of view of the large FOV camera is 100°-55°, and / or the field of view of the small FOV camera is 55°-30°; the distance between the optical centers of the large FOV camera and the small FOV camera is 5° -10mm; the optical center distance between the large FOV camera and the mono camera is 5-10mm; the field of view of the large FOV camera is the ...

Embodiment 3

[0067] A readable storage medium stores a computer program for execution by a processor. When the processor executes the computer program, the multi-camera shooting method described in Embodiment 1 is performed.

Abstract

The invention discloses a multi-camera shooting method and shooting terminal, and a readable storage medium. The shooting method comprises: a large FOV camera and a small FOV camera are started in a preview mode and a large FOV image and a small FOV image are obtained respectively; a light-changing region between the large FOV image and the small FOV image is calculated; the large FOV image is displayed as a preview image on a display screen and a light-changing area is marked on the large FOV image; a touch operation of a touch screen is acquired; if the obtained touch operation is a preset first light-changing operation, switching to a first light-changing mode is carried out; if the obtained touch operation is a preset second light-changing operation, switching to a second light-changing mode is carried out; and a shooting instruction is obtained and a light-changing image or the large FOV image is outputted. Therefore, a problem of losing of a shot target or composition shift occurrence after optical zooming is solved; and the user is able to carry out optical zooming shooting conveniently.

Description

technical field [0001] The present invention relates to the field of multi-cameras, and in particular to a multi-camera shooting method, a shooting terminal and a readable storage medium. Background technique [0002] The rapid development of mobile terminals such as smart phones and tablet computers has made the functions of these mobile terminals more and more powerful, which has far exceeded the single function of communication. The shooting function is the most important function on the mobile terminal besides the communication. [0003] With the development of mobile terminal photographing technology, the optical zoom function can already be realized on the mobile terminal. The solution to achieve optical zoom on mobile terminals is to use a large FOV camera and a small FOV camera. The large FOV camera can obtain a large FOV image (wide-angle image), and the small FOV image can obtain a small FOV image (telephoto image). When the user selects the magnification of shoo...
