Title:
GRAYSCALE DATA DETERMINATION METHOD AND APPARATUS, AND DEVICE AND SCREEN DRIVE BOARD
Document Type and Number:
WIPO Patent Application WO/2022/057495
Kind Code:
A1
Abstract:
A grayscale data determination method and apparatus, and a device and a screen drive board. The method comprises: acquiring a source image, wherein the source image comprises a plurality of pixel points; respectively calculating a weighted value of each channel value of a first pixel point and a channel value of a corresponding color of a second pixel point, so as to obtain a pixel value of a third pixel point, wherein the first pixel point is a pixel point, which corresponds to a first edge (12), in the source image, and the second pixel point is a pixel point, which is adjacent to the first pixel point, in the source image; replacing a pixel value of the second pixel point in the source image with the pixel value of the third pixel point, so as to obtain a first image; and determining grayscale data of a first panel (10) and grayscale data of a second panel (20) on the basis of the first image, wherein the grayscale data of the first panel (10) comprises a grayscale value of a main pixel (11), and the grayscale data of the second panel (20) comprises a grayscale value of an auxiliary pixel (21).
