AI Technical Summary

Technical Problem

In the prior art, the method of manually modifying the image saturation is cumbersome and has low efficiency; the method of image processing equipment performing enhancement algorithms is difficult to judge the degree of image color enhancement, and the image color enhancement effect is poor.

Method used

By obtaining the RGB data of the color image, the color characteristic value is calculated, and based on the inverse relationship between the color characteristic value and the color enhancement coefficient, the corresponding color enhancement coefficient is determined, and it is used as the weight of the color component of the adjustment image to perform color enhancement processing on the image.

Benefits of technology

The effect of image color enhancement processing is improved, ensuring that appropriate color enhancement processing is carried out under different image color richness, avoiding the problems of oversaturation or undersaturation, and improving the image visual effect.

Abstract

The disclosed embodiments relate to an image color enhancement method, device, equipment and storage medium, which obtains a first color image, calculates the color feature value of the first color image based on the RGB data of the first color image, determines the color enhancement coefficient corresponding to the first color image based on the inverse relationship between the preset color feature value and the color enhancement coefficient, and uses the color enhancement coefficient as a weight to adjust the color component of the first color image, performs color enhancement processing on the first color image, and obtains an enhanced second color image. The solution provided by the disclosed embodiments can ensure that a large degree of color enhancement processing is performed on the image when the image color richness is low, and a large degree of color enhancement processing is performed on the image when the image color richness is low, thereby improving the effect of image color enhancement processing.
