Image color enhancement method and device, equipment and storage medium

The invention relates to the technical field of image processing, and discloses an image color enhancement method and device, equipment and a storage medium, and the method comprises the steps: converting an obtained RGB source image into a Lab color space image; and determining an enhancement threshold value of the Lab color space image based on the a * component corresponding to each pixel point in the Lab color space image. And adjusting the a * component of the Lab color space image according to the enhancement threshold and a set adjustment parameter. In order to solve the problem of color layering, interpolation operation can be performed on the adjusted a * component to obtain an enhanced a * component. And after the enhanced a * component is combined with the L * component and the b * component included in the Lab color space image, color space conversion is carried out, so that the RGB image after color enhancement is obtained, and the enhancement effect of the image is improved under the condition t
