Abstract

The invention discloses an image tone mapping method and device, electronic equipment and a storage medium, and belongs to the technical field of image processing. The image tone mapping method comprises the following steps: performing color gamut compression processing on a target image to obtain a first image; and performing brightness compression processing on the first image to obtain a second image.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image tone mapping method, device, electronic equipment and storage medium. Background technique [0002] Professional photography functions, such as high dynamic range imaging (High-Dynamic Range, HDR), super night scene, etc., are widely used in mobile phone photography. Since ordinary display screens can only display low-bit-width images (LowBit Image, LBI) with a bit-width of 8bit, etc., in order to adapt to the display, based on the above-mentioned professional functions, the collected multi-frame photos are synthesized to generate a high-bit-width image (HighBitImage, After HBI), the high-bit-width image needs to be compressed into a low-bit-width image. [0003] The process of compressing a high-bit-width image into a low-bit-width image and maintaining the overall brightness and contrast in line with human observation is called Tone-Mapp...
