Abstract: This application provides an image display method for an electronic device, an encoding method, and a related apparatus. The image display method for an electronic device includes: obtaining a to-be-processed image; obtaining high-luminance enhancement data, where the high-luminance enhancement data includes a high dynamic range layer (hdrLayer); obtaining initial backlight luminance of the electronic device; obtaining target backlight luminance of the electronic device based on the initial backlight luminance; performing luminance adjustment on the to-be-processed image based on the hdrLayer to obtain a target image for the target backlight luminance; and displaying the target image at the target backlight luminance. In this application, a luminance range of a screen can be fully utilized for image display, and optimal end-to-end experience is achieved.

Abstract: This application discloses an image processing method and a related apparatus, to support display of an HDR image, display more dynamic ranges and image details, provide richer colors, and improve user experience. The image processing method includes: obtaining a first RGB image, where the first RGB image is an RGB image sensed by a photographing apparatus; converting the first RGB image into a second RGB image, where the second RGB image is an image meeting a BT2020 color gamut range; determining a first luminance value corresponding to the second RGB image, where the first luminance value indicates maximum luminance of each frame of image in the second RGB image; determining a target image based on the first luminance value and the second RGB image; and sending the target image to a display apparatus, so that the display apparatus displays the target image.
