Abstract

The invention relates to the technical field of image processing and provides a white balance processing method and device, a terminal device and a memory medium. The white balance processing method comprises the steps of obtaining a to-be-processed image; collecting RGB values of pixels of the to-be-processed image; determining white balance statistics points of the to-be-processed image according to the RGB values of the pixels; calculating a mean value of the statistics points within a quasi white area as a first gain value when a proportion of the statistics points within the quasi white area in the white balance statistics points is greater than a first threshold, wherein the quasi white area is formed by stretching a white area of white balance around for certain distance; moving thefirst gain value towards the white area for preset distance to obtain a second gain value if the first gain value is in the quasi white area and out of the white area; and carrying out white balanceprocessing on the to-be-processed image through adoption of the second gain value.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a white balance processing method, device, terminal equipment and computer storage medium. Background technique [0002] White balance is aimed at different color temperature conditions, by adjusting the color circuit inside the camera to make the captured image offset the color cast, closer to the visual habits of the human eye. White balance can be simply understood as under any color temperature condition, the standard white captured by the camera lens is still white after being imaged after being adjusted by the circuit. [0003] At present, a common white balance processing method is the gray world method within the white area based on prior knowledge. Based on the prior knowledge of a specific digital image sensor, this method sets a white area, and the statistical points that fall into the white area are considered white points, while the statistical poin...
