Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a method for adjusting image color saturation, which aims to solve the problem that all pixels in a frame of image use the same saturation coefficient in the prior art, and it is difficult to ensure that the color noise in the dark area of ​​the image is more accurate. Minor issue while making other areas more vibrant

Embodiment Construction

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] In the embodiment of the present invention, by dividing the chromaticity interval, setting the saturation adjustment parameter corresponding to the chromaticity interval, judging the chromaticity interval in which the pixel is located according to the obtained chromaticity value of the pixel point, and obtaining the saturation coefficient of the pixel point , calculates the new chromaticity value of the pixel point, and realizes the saturation adjustment of the color of the pixel point of the image in different chromaticity intervals.

Abstract

The invention is applied in the field of image processing, and provides a method for adjusting the color saturation of an image. The method comprises the following steps: judging a chromaticity section in which a current pixel point is positioned according to a chromaticity value of the current pixel point; acquiring a saturation coefficient of the current pixel point according to the chromaticitysection in which the current pixel point is positioned and a saturation adjustment parameter corresponding to the chromaticity section; and adjusting the chromaticity value of the current pixel pointaccording to the chromaticity coefficient of the current pixel point. The method for adjusting the color saturation of the image ensures that color noises in a dark region of the image are lower, andsimultaneously the colors of other regions are brighter.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method and system for adjusting the color saturation of an image. Background technique [0002] Digital images are widely used in daily life and in all walks of life, and image saturation processing is a way to adjust the color performance of digital images. Saturation refers to the vividness of color, also known as color purity. White, gray and black are called achromatic, and the saturation depends on the ratio of chromatic components and achromatic components in the color. The larger the color component, the greater the saturation, and the brighter the color; the larger the achromatic component, the smaller the saturation, and the grayer the color. [0003] Color saturation processing is generally a digital gain process used to enhance the vividness of color images. The traditional image saturation processing method is to let all pixels in a frame of image use ...
