Document Type and Number:
WIPO Patent Application WO/2023/284528
Kind Code:
A1
Abstract:
An image enhancement method, comprising: acquiring image adjustment parameters (S202), the image adjustment parameters comprising a brightness adjustment parameter and a chromaticity adjustment parameter; converting first image data to be processed into second image data (S204), the second image data comprising brightness data and chromaticity data; adjusting the brightness data on the basis of the brightness adjustment parameter to obtain adjusted brightness data, updating the brightness adjustment parameter when the adjusted brightness data does not meet a preset brightness enhancement condition, and continuing to adjust the adjusted brightness data on the basis of the updated brightness adjustment parameter until the final adjusted brightness data meets the brightness enhancement condition (S206); adjusting the chromaticity data on the basis of the chromaticity adjustment parameter to obtain adjusted chromaticity data, updating the chromaticity adjustment parameter when the adjusted chromaticity data does not meet a preset chromaticity enhancement condition, and continuing to adjust the adjusted chromaticity data on the basis of the updated chromaticity adjustment parameter until the final adjusted chromaticity data meets the chromaticity enhancement condition (S208); performing image color dimension conversion on the brightness data which meets the brightness enhancement condition and the chromaticity data which meets the chromaticity enhancement condition to obtain third image data belonging to the same color dimension as the first image data, and using the third image data as the result of the first image data undergoing image enhancement processing (S210).
