COLOR CORRECTION METHOD AND DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM THEREOF
摘要:
A color correction method and device, and computer-readable storage medium thereof, the color correction method including: obtaining an image to be corrected and a color temperature of the image, the image being in a YUV color space; determining first and second adjacent quadrants in a UV plane associated with each pixel point in the image according to a position of the pixel point on the UV plane; and performing color correction on each pixel point using correction matrices respectively corresponding to the first and second adjacent quadrants and the image color temperature, each correction matrix being calculated in advance of the color corrections according to the chrominance value of a color patch in each of the first and second quadrants, the color temperature, and a standard value corresponding to the color patch.
