The present application provides a histogram equalization method that can reduce color difference while enhancing color image details. The method processes only the brightness data of the color image to ensure the originality of the color data, thereby enhancing the brightness details of the image and reducing color difference. Then, by analyzing the type of the non-zero histogram of the Y component data of the color image, whether it is a unimodal histogram or a multimodal histogram, the correction parameter is used to obtain a suitable platform value and a corrected histogram. If it is a unimodal histogram, it is judged that the current image color is relatively single, and it is necessary to perform contrast enhancement while ensuring that the color difference is small enough, so a larger correction parameter is selected; if it is a multimodal histogram, it is judged that the current image is relatively complex, and the contrast enhancement effect is improved by reducing the correction parameter. Finally, a platform histogram is obtained using a suitable platform value and a corrected histogram, and the platform histogram is equalized to obtain the final color image data.
