Image processing method, electronic device, storage medium and computer program product

Abstract

This application discloses an image processing method, an electronic device, a computer-readable storage medium, and a computer program product. In this method, the electronic device displays an HDR image or displays a first SDR image based on a first SDR image and a first gain map; in response to an image editing operation, the first SDR image is edited to obtain a second SDR image, and a second gain map is obtained based on dynamic range transformation information and the second SDR image; the second gain map and the second SDR image are stored; and the edited HDR image is displayed based on the second gain map and the second SDR image. The dynamic range transformation information is obtained based on the first SDR image and the first gain map, and is used to describe the transformation relationship from a standard dynamic range image to a high dynamic range image; the second gain map is a gain map that includes the edited content corresponding to the image editing operation. This application embodiment can still present an HDR effect after image editing.
