Problems solved by technology

Since the camera parameters of multiple cameras are difficult to be consistent, the spliced ​​video will have obvious defects of inconsistent light and dark areas
[0003] In the existing technology, exposure compensation is used to perform global exposure compensation on each image to be stitched, so that the stitched image has a poor exposure effect, and some areas are often overexposed and some areas are underexposed.

Abstract

The embodiment of the invention discloses an information processing method and an electronic device. The electronic device is used for determining an image brightness difference value of a first image and a second image at an image stitching part; if the image brightness difference value meets a first preset condition, determining a first image region of the first image at the image stitching part, and determining a second image region of the second image at the image stitching part; and based on the brightness of the first image region and the brightness of the second image region, respectively performing exposure compensation for the first image and the second image.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an information processing method and electronic equipment Background technique [0002] Camera equipment capable of wide-angle photography or panoramic photography is currently a hot direction in the industry. It can not only help users get a panoramic view at one time picture You can even get panoramic video (panoramic video). Because the distortion of a single wide-angle camera is relatively large, it is difficult to obtain a correct image even with the method of distortion correction. Therefore, most of the solutions for panoramic cameras are formed by splicing images from multiple cameras with small viewing angles (FOV). Since the shooting parameters of multiple cameras are difficult to be consistent, the spliced ​​video will have obvious defects of inconsistent light and dark areas. [0003] In the prior art, exposure compensation is used to perform ...
