Document Type and Number:
WIPO Patent Application WO/2018/035899
Kind Code:
A1
Abstract:
An image processing method, comprising the following steps: calculating an average value of each pixel gray value of a global original image (a); calculating an average value and a median of all pixel gray values of each local image (b1); calculating a Mura threshold of each window (b2); calculating a Mura compensation value for each pixel in a local original image (c); adding the gray value of each pixel of the local original image to the Mura compensation value to obtain a gray value of each pixel of the updated local image (d); displaying the updated image (e); calculating a standard deviation according to gray values of an image obtained after multiple updates and an average value of all the pixels (f); comparing the standard deviation with a preset value (g); if the standard deviation is greater than the preset value, executing (b1); and if the standard deviation is lower than or equal to the preset value, generating a Mura compensation table according to the calculated standard deviation, and compressing and storing the Mura compensation table (h).
