Picture color conversion method, device, equipment and readable storage medium

Abstract

The invention discloses a picture color conversion method. The method comprises the following steps: collecting an original picture to be subjected to color conversion and a color conversion type; obtaining an original RGB channel component corresponding to each original pixel point in the original picture; when the color conversion type is black and white effect processing, performing weighted calculation on each original RGB channel component for each original pixel point; determining each black and white pixel point according to each first weighting calculation result to obtain a black and white effect picture; and when the color conversion type is coloring effect processing, performing concentration and saturation adjustment on each target color pixel point in the target coloring effect picture to obtain adjusted RGB channel components, and generating the target coloring effect picture in combination with each original RGB channel component and each adjusted RGB channel component. According to the invention, the color conversion efficiency is greatly improved, and the space consistency of the color in the transfer process is ensured. The invention further discloses a device, equipment and a storage medium, which have corresponding technical effects.

Description

Technical field [0001] Technical Field The present invention relates to image processing, more particularly to a color image conversion method, apparatus, equipment and computer-readable storage medium. Background technique [0002] In the transmission and exchange of information, the media image is important. In the human visual system, color is an important factor reflected in visual cognition. Sometimes the original picture proofs can not display the user's needs, this time on the need for picture processing, such as switching pictures of scenes in different styles. [0003] Existing large color picture color conversion method for converting color transfer methods are based. Currently, in the study based on the color transfer coloring process, since the target grayscale image, the rendering process at each pixel is independent, so this conventional method of color conversion usually occurs during the transfer inconsistent color space the problem, and the image color conversion...

AI Technical Summary

Problems solved by technology

At present, in the research of coloring methods based on color transfer, since the coloring process at each pixel in the target grayscale image is independent, this traditional color conversion method usually has inconsistencies in the color space during the transfer process. problem, and the image color conversion process is complicated and the conversion efficiency is low
