Abstract

The invention provides an image processing method, and the method comprises the steps: firstly carrying out the contrast-enhanced image processing on an original image in the same color space, so as to solve problems of tone shift and detail loss, furthermore, carrying out self-adaptive saturation compensation image processing on contrast output pixels according to an original image brightness value and a contrast output brightness value, so that the attenuated saturation due to the contrast enhanced image processing is compensated, and the problem of saturation reduction is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular to an image processing method for improving the problems of hue shift, detail loss, and saturation reduction. Background technique [0002] With the advancement of technology, people have higher and higher requirements for the quality of color images. In order to improve the quality of color images, image processing is usually performed to increase contrast and enhance saturation, so that the color images seen by human eyes can be closer to the real scene. , so color adjustment techniques are becoming more and more important. [0003] Improving the contrast of color images helps to improve visual perception. Therefore, in existing image processing methods, the color images in the RGB color space are usually input and converted to Hue-Saturation-Intensity (HSI). ) color space to perform image processing to improve contrast, and then perform histogram statistics,...
