AI Technical Summary
Technical Problem
In existing technologies, the use of elliptical models for skin color detection and enhancement has high hardware overhead and lacks universality, making it difficult to effectively enhance other memory colors, such as the colors of the sky and green plants.
Method used
By obtaining the color index value of the image pixels, traversing the preset color lookup table (LUT), determining the memory color type, calculating the color adjustment amount, and performing color adjustment, a color-enhanced image is obtained.
Benefits of technology
It improves computational and storage efficiency, enabling the determination of a suitable color enhancement scheme for an image in a short time, thereby improving the efficiency and accuracy of color enhancement.

Abstract
The present disclosure provides a color enhancement method, device, equipment and storage medium, and relates to the technical field of image processing. The method comprises: acquiring a color index value corresponding to each pixel point in each dimension in a to-be-processed image; based on the color index value of each pixel point in each dimension, traversing a first preset color lookup table (LUT) associated with the dimension to obtain a target type of a memory color corresponding to the pixel point; according to the target type of the memory color and the corresponding color index value of each pixel point, traversing a second preset LUT to obtain a color adjustment amount corresponding to the pixel point; and based on the color adjustment amount corresponding to each pixel point, performing color adjustment on each pixel point to obtain a target image after color enhancement. Thus, when performing color enhancement on the to-be-processed image, through memory color enhancement, the target image can better meet the user's expectation of color, and the user experience is improved.
