An Evaluation Method for the Color Quality of Digital Hardcopy Output SRGB Image

摘要

Aim at evaluating effectively the color quality of digital hardcopy output sRGB images, the assessment method for color quality of digital hardcopy output sRGB images is established. It focuses on the memory color, which designs the assessment color targets to reflect the chroma characteristics of typical memory color (skin color, sky blue color, grass green and cole flower yellow color), it combines the subjective evaluation experiment to ensure the compared scale for chromatic value of color targets of each typical memory color. It carries out the compared analysis for the assessment color lump and chromatic value of actual output and the compared scale, gives out the evaluation of the color quality of hardcopy output sRGB images from three aspects of lightness, chroma and hue. The established method not only can evaluate effectively the color quality of digital hardcopy output sRGB images, but also can provide the technical support for improving and optimizing the color quality of hardcopy output.
