Problems solved by technology

[0004] However, after saturation processing is performed on the image using the saturation processing scheme in the related art, it is easy to make the saturation adjustment of some areas of the image too large, while the saturation adjustment of some areas of the image is too small, so that the image after saturation adjustment is displayed not effectively

Abstract

The embodiment of the application discloses an image saturation adjustment method, device, storage medium and terminal. The method includes: acquiring the RGB image to be processed; traversing each pixel in the RGB image to determine the original RGB component corresponding to each pixel in the RGB image; for each pixel, according to the current pixel corresponding The original RGB component and the obtained color gamut mapping lookup table determine the target RGB component corresponding to the original RGB component; the original RGB component corresponding to each pixel in the RGB image is adjusted to the original RGB component corresponding to The target RGB component, generating a saturation-adjusted target image. By adopting the above-mentioned technical solution, the saturation of the RGB image is directly adjusted, avoiding the mutual conversion between the RGB color space and the HSV color space, effectively saving the time for image color space conversion, and effectively improving the image display effect.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an image saturation adjustment method, device, storage medium, and terminal. Background technique [0002] With the rapid development of terminal technology, electronic devices such as mobile phones and tablet computers have image acquisition functions, and users have higher and higher requirements for the quality of images collected by terminals. [0003] At present, after an image is collected, saturation processing is generally performed on the image, so as to adjust the saturation of the collected image. In the related art, the saturation adjustment of the image can be realized by obtaining an image in the HSV color space, and multiplying the saturation component (S component) of each pixel in the HSV color space image by a fixed saturation gain coefficient . [0004] However, after saturation processing is performed on the image us...
