Document Type and Number:
WIPO Patent Application WO/2023/245364
Kind Code:
A1
Abstract:
An image processing method and apparatus, an electronic device, and a storage medium. The image processing method comprises: obtaining a light spot layer and a background layer of an image to be processed (S210); obtaining a first coefficient layer and a second coefficient layer according to the light spot layer and the background layer (S220); processing an original vignetting mask layer on the basis of the first coefficient layer and the second coefficient layer (S230); and on the basis of a target vignetting mask layer obtained after processing, fusing a blurred image of the image to be processed so as to obtain a target image (S240). When a vignetting effect is added to the blurred image, good brightness and contrast of highlighted pixels can be retained, the transition of the boundary between a light spot region and a background region is smoother and more natural, and the imaging quality is improved.
