Title:
IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/056351
Kind Code:
A1
Abstract:
An image processing method, comprising: constructing an image data analysis model, wherein the image data analysis model is used for representing the relationships between the actual light transmittance of a display panel and first light transmittance of a dimming subpanel (1), and between the actual light transmittance of the display panel and second light transmittance of a display subpanel (2) (S100); acquiring a first gray scale of at least one first subpixel (101) in a plurality of first subpixels (101) and second gray scales of at least two second subpixels (201) corresponding to each of the at least one first subpixel (101) (S200); acquiring the first light transmittance corresponding to the first gray scale of the at least one first subpixel (101) and the second light transmittance corresponding to the second gray scales of the at least two second subpixels (201) corresponding to each of the at least one first subpixel (101), and respectively determining, according to the image data analysis model, the actual light transmittance corresponding to the second gray scales of the at least two second subpixels (201) (S300); and respectively acquiring a target light transmittance corresponding to the second gray scales of the at least two second subpixels (201), and determining, according to the actual light transmittance and the target light transmittance corresponding to the second gray scales of the at least two second subpixels (201), a compensation gray scale corresponding to the at least two second subpixels (201) (S400).
