White balance processing method, device and device for panoramic shooting

Abstract

The present application proposes a white balance processing method, device and equipment for panoramic shooting, wherein the method includes: determining M frames from the captured N frames of original images according to the scene information of the panoramic shooting as a reference image, wherein M and N are both greater than 1, and M is less than or equal to N; apply the preset white balance algorithm to obtain the white balance gain parameters of M frames of reference images, perform white balance processing on N frames of original images according to the white balance gain parameters of M frames of reference images, and obtain the corresponding The N frames of color-corrected images; the N frames of color-corrected images are synthesized to generate a panoramic photo. Therefore, this method solves the problem of the global color cast of the panorama photo when the color of the first frame of reference image deviates when the white balance gain parameter of the first frame of reference image is fixedly used to perform white balance processing on N frames of original images in the prior art. Technical problems that seriously affect the look and feel of panoramic photos have improved the white balance processing effect of panoramic photos to meet user needs.

Description

technical field [0001] The present application relates to the technical field of photography, and in particular to a white balance processing method, device and equipment for panoramic photography. Background technique [0002] Currently, most shooting devices support automatic white balance adjustment. In the related art, for the panoramic shooting mode, the global white balance gain parameter is fixed, that is, the R channel gain value and the B channel gain value generated in the first frame are used to perform white balance processing on the original images of all frames. However, if the white balance gain parameter of the first frame is wrongly judged and the color deviates, the wrong white balance gain parameter will be used in the original images of all subsequent frames, resulting in a global color cast in the final panoramic photo, which is serious. Affects the look and feel of panoramic photos. Contents of the invention [0003] The present application provides...
