20 Claims

1. A video encoding method, performed by a server, the video encoding method comprising:

obtaining a current image frame;

performing video image enhancement on a target region in the current image frame, to generate an image-enhanced image frame, the target region comprising a region in which hopping occurs in a pixel value of a pixel in the current image frame,

wherein the performing the video image enhancement comprises enhancement of the target region on a pixel-by-pixel basis, and wherein enhancement of each respective pixel in the target region is based on a same pixel sampling pattern, the same pixel sampling pattern comprising pixels located in odd-numbered rows and odd-numbered columns in a pre-determined square and pixels adjacent to the respective pixel, and

wherein an enhanced pixel value of each respective pixel in the target region is based on a pixel value of the respective pixel and a preset pixel enhancement parameter, the preset pixel enhancement parameter being same for each respective pixel in the target region; and

encoding the image-enhanced image frame.
