White balance information synchronization methods and devices and computer readable medium

Abstract

The embodiments of the invention disclose white balance information synchronization methods and devices and a computer readable medium. A method comprises the steps of obtaining a first image and a second image, wherein the first image is an image collected by a first camera, and the second image is the image collected by a second camera; determining corresponding first coordinate points and firstreference coordinate points of white balance gain of the first image in a target coordinate system, wherein the first reference coordinate points are N corresponding coordinate points of the first camera in the target coordinate system; and determining second coordinate points according to the first coordinate points, the first reference coordinate points and second reference coordinate points, and determining the white balance gain of the second image according to the second coordinate points, wherein the second coordinate points are the corresponding coordinate points of the white balance gain of the second image in the target coordinate system. According to the embodiments of the invention, synchronization of white balance information can be rapidly realized, computing is simple, and precision is relatively high.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a white balance information synchronization method, device and computer readable medium. Background technique [0002] In order to obtain a better photographing experience, more and more cameras are used on photographing devices. Since multiple cameras on the same photographing device often use sensors and lens modules of different models, or even different manufacturers, this may result in obvious differences in the light-sensing characteristics of different cameras. According to the application requirements of multi-cameras, the camera effects need to be synchronized among the multiple cameras. Whether the effect of automatic white balance (AWB) is consistent largely determines whether the colors of images captured by multiple cameras are consistent. Therefore, it is necessary to deal with the synchronization problem of multi-camera automatic white balance. ...

AI Technical Summary

Problems solved by technology

In practical applications, due to differences in the lenses, photosensitive chips and other devices of different cameras, after the images captured by multiple cameras are processed by white balance, the colors of the multiple images obtained will be different, which directly affects the image effect after splicing
