Image shooting method and device based on double cameras

Abstract

The invention discloses an image shooting method based on double cameras. The method comprises that the main camera carries out shooting according to a first object-part focus to obtain a first image; the auxiliary camera carries out shooting according to a second object-part focus to obtain a second image; the depth information value of each pixel point in the main or auxiliary camera is obtained according to the obtained first and second images; pixel alignment is carried out on data overlapped areas of the images obtained by the main and auxiliary cameras; and a full-depth-of-field image is generated according to the depth information values, the first object-part focus, the second object-part focus and the overlapped images of the main and auxiliary cameras. The invention also discloses an image shooting device based on the double cameras.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a method and device for capturing images based on dual cameras. Background technique [0002] With the vigorous development of the Internet industry, there are more and more users of mobile terminals, and the functions of the mobile terminals are becoming more and more powerful, such as taking pictures, taking pictures, surfing the Internet, playing games and so on. Among them, with the continuous improvement of people's living standards, the requirements for taking pictures are also getting higher and higher, such as using mobile terminals to realize the effect of panoramic depth images. [0003] Depth of field refers to the range of clear imaging before and after the focus point, that is, when the lens focuses on a certain point, it will focus this point into a clear image on the imaging medium. In this way, not only this point is clear, but also the front and rear of the ...

Problems solved by technology

Therefore, when shooting close-ups, the focal length is close and the depth of field is relatively shallow, resulting in blurred backgrounds in the distance; Subjects are often partly clear and partly blurred, unless they are very small objects

[0005] The above-mentioned method of obtaining a panoramic depth image requires the user to manually select the clear parts of the near view and distant view for synthesis in the post-stage synthesis of the image. Therefore, the operation process is relatively cumbersome; and it is only suitable for professional users, not for ordinary users.

In addition, due to the need to use a single camera for multiple shots, the angle and position of the shots cannot be changed at the same time, otherwise the images cannot be accurately synthesized, which leads to a very limited shooting scene
