Title:
GRAYSCALE MEASUREMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/082370
Kind Code:
A1
Abstract:
A measurement method and apparatus. The method comprises: collecting first partial grayscale data of an LED screen when an image is displayed (S102); determining the type of a chip which drives the LED screen (S104); and predicting second partial grayscale data of the LED screen according to the type of the chip and the first partial grayscale data (S106). Therefore, the technical problem in the related art of low grayscale measurement efficiency due to step-by-step measurement required for grayscale measurement is solved.
