Optimized color chart realization method based on color generation adaptation representation of digital equipment

Abstract

The invention relates to an optimized color chart realization method based on color generation adaptation representation of digital equipment. The method includes three sections of color chart matching adaptation, color chart optimization and color chart application effect evaluation. According to the method, a basic color chart used for representing color generation characteristics of the equipment is selected, the basic color chart is output in the optimal state of equipment calibration, data values of chroma data L*a*b* of a series of color points of the color chart are acquired by means of a color measuring instrument, and corresponding ICC characteristic files are generated; depending on a ProfileEditor evaluation system, color generation difference in a two-dimensional plane color reappearing range at various lightness levels is analyzed; according to the color generation difference analysis result, quantitative extraction and optimized combination are performed on the key color points affecting the color generation adaptation representation of the equipment, and after loop optimization, an optimized color chart capable of being used for accurately representing the color generation adaptation of the digital equipment is acquired finally; at last, the application effect of the optimized color chart is evaluated systematically. The method solves the problems that when a current basic color chart is used for representing some fixed digital equipment, color generation adaptation difference is large and colors are distorted.

Description

technical field [0001] The invention relates to a computer image processing technology, in particular to a method for realizing an optimized color table based on the characterization of the color suitability of a digital device. Background technique [0002] With the development of computer technology, multimedia and network technology, the use of various image input devices, display devices and output devices (such as scanners, monitors, color printers, etc.) is becoming more and more popular. Due to the differences in color rendering mechanism and color gamut range between different devices, it is becoming more and more difficult to accurately transfer, reproduce and process color images between these devices. Therefore, the problem of color distortion in the process of accurate transmission and reproduction of color images between different devices has attracted people's attention, not only because it is hoped that the color images reproduced between different devices can...
