Abstract

The invention discloses a method for regulating the image saturation degree. The method comprises the following steps that RGB (red green blue) images are received, parameters are regulated, and the RGB value before the image saturation degree regulation is extracted on the basis of the received RGB image; the RGB value before the image saturation degree regulation and the regulation parameters are substituted into the relational expression of the RGB value after the image saturation degree regulation and the RGB value before the image saturation degree regulation, and the RGB value after the image saturation degree regulation is obtained through calculation, wherein the relational expression is obtained through calculation by an RGB to HIS (hue saturation intensity) formula, a saturation regulation formula and an HIS to RGB formula; the RGB image is subjected to saturation degree regulation on the basis of the RGB value after the image saturation degree regulation, and an RGB image after the regulation is obtained; the RGB image after the regulation is output. The invention also discloses a device for regulating the image saturation degree.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for adjusting image saturation. Background technique [0002] With the development and popularization of computer technology and image processing technology, the application of digital image processing is becoming more and more extensive. During the acquisition process, the image is affected by factors such as sensors, noise interference or quantization, compression, etc., resulting in the image not being able to achieve a satisfactory visual effect. In order to improve the visual effect, it is very necessary to enhance the original image. [0003] Color digital images can be represented by a variety of color space models, such as RGB, YUV, HSV, and HSI. in: [0004] RGB space model: a color model produced by the color mixing principle of three primary colors. The three primary colors are red, green, and blue, respectively represented by R, G, and ...
