Abstract: An image capture method, an image display method, and an apparatus are provided to reduce a difference between an image displayed on a display end and an image displayed on a capture end. During encoding, the capture end transmits data for describing a luminance mapping relationship between a before-compression image and an after-compression image to the display end, so that consistency between the image on the capture end and the image on the display end is ensured as much as possible. In addition, screen related information for describing luminance of the capture end is transmitted to the display end, so that the display end adjusts backlight and a pixel value based on the screen related information, to improve consistency between the image on the capture end and the image on the display end.

Abstract: This application provides a picture processing method. The method includes: The encoder side obtains a to-be-processed picture, obtains a plurality of groups of visual sensory experience parameters, and encodes the to-be-processed picture and the plurality of groups of visual sensory experience parameters. At a decoder side, the method includes: The decoder side obtains a to-be-processed picture, obtains a zoom-in operation instruction, obtains one or more groups of visual sensory experience parameters corresponding to one or more local pictures, and separately processes the corresponding local picture based on the one or more groups of visual sensory experience parameters to obtain a processed local picture.
