Abstract

This application discloses a white balance processing method and device based on RGB space. In this method, after obtaining the original values ​​of each pixel in the image to be processed in the three color channels of R, G, and B, the pixel is calculated The difference between red and blue, and the middle gray pixel is determined through the red and blue difference and the judgment condition of the middle gray pixel. The ratio of the total number of pixels in the image to be processed is calculated to obtain the gain values ​​of the pixels in the three color channels of R, G, and B respectively, and according to the gain value, the correction value of the pixel is obtained, and then the pixel in the image to be processed The original value of each pixel in the three color channels of R, G, and B is adjusted to the corrected value to realize the white balance processing of the image to be processed. Through the solution disclosed in the present application, it is possible to implement white balance processing on the image, thereby reducing the color difference in the image and improving the image quality.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a white balance processing method and device based on RGB space. Background technique [0002] Different light sources have different spectral components and distributions, and this phenomenon is called color temperature in colorimetry. The same white object will have color difference when illuminated by light sources with different color temperatures. For example, under the light source with low color temperature, the white object will appear reddish, while under the light source with high color temperature, the white object will appear blue. [0003] Among them, correcting the color difference caused by different color temperatures, so that white objects appear truly white, is called white balance. For example, the human visual system can automatically adjust the light sensitivity according to the color temperature of the current light sourc...
