Abstract
(EN)
Disclosed in the embodiments of the present application are a video processing method and apparatus, an electronic device and a storage medium, relating to the technical field of electronic devices. Said method is applied to the electronic device, and comprises: when the electronic device plays back a video resource file, measuring a current distance between the display screen and a user; determining, on the basis of the current distance, target optimization parameters corresponding to the current distance; and performing display enhancement processing on the video resource file on the basis of the target optimization parameters. The display enhancement processing processes an image in the video resource file by means of the target optimization parameters, so as to improve the video image quality of the video resource file. The video processing method and apparatus, the electronic device and the storage medium provided in the embodiments of the present application determine different optimization parameters according to different distances between the display screen and the user, so as to perform display enhancement processing on the video resource file by means of the optimization parameters corresponding to the distances between the display screen and the user, improving the display effect of a video image.
