Abstract

Embodiments of the present application provide an image color correction method, device, electronic equipment, and machine-readable medium. It belongs to the technical field of image processing. The method includes: obtaining an image to be color-corrected and corresponding color-calibration requirement information; reading a binary file satisfying the color-correction requirement information from a disk according to the color-correction requirement information, and the binary file includes binary data ; Wherein, the binary data is obtained by converting the LUT data in the LUT file; the binary file is converted into a target color lookup table and stored in memory, the target color lookup table includes decimal data, wherein the decimal The data is obtained by converting the binary data; in the internal memory, the target color look-up table is used to perform color correction processing on the image to be corrected to obtain the corrected image. Using the image color correction method provided by this application can make the running speed of the color correction file faster.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an image color correction method, device, electronic equipment, and machine-readable medium. Background technique [0002] Color calibration is an important part of video shooting and editing. By adjusting brightness, contrast, color and other aspects, it can make up for the image quality defects caused by insufficient environment, equipment, experience, etc., and improve the overall picture quality of the video and screen perception. [0003] In the current color correction process, users usually use the LUT tool to correct the color of the picture, and the LUT tool can convert one color effect into another color effect on the image. [0004] However, due to the huge space occupied by the LUT tool, when the user uses the LUT tool for color correction, the process of opening the LUT tool and running the LUT tool is relatively slow. Con...
