Document Type and Number:
WIPO Patent Application WO/2024/046105
Kind Code:
A1
Abstract:
The present application belongs to the field of image rendering. Disclosed are an anti-aliasing method and apparatus for an image, and a device, a medium and a program product. The method comprises: acquiring a first edge pixel of an image in an HDR space (310); generating a first scaling factor according to a local brightness environment where the first edge pixel is located (320); according to brightness values of a plurality of pixels in an image block where the first edge pixel is located, generating a color ratio to be processed which corresponds to the first edge pixel (330); scaling said color ratio on the basis of the first scaling factor, so as to obtain a first color ratio (340); according to a color value of the first edge pixel and a color value of a target pixel, performing mixing in combination with the first color ratio to obtain a first color value (350); and updating the first color value to the color value of the first edge pixel (360). The solution solves the contradiction, under a detail anti-aliasing branch, between an image detail definition and an anti-aliasing effect of a highlight area.
