Therefore, only using the existing CIE1931 and CIE1964 sets to represent the observer's average color vision characteristics and considering the different viewing fields of color matching functions is not enough to characterize the cone cell responses of different observers

Embodiment Construction

[0034] In the present invention, the printed reflective color and the self-luminous color presented by the display are used as color matching sample pairs, and 8 hue colors and neutral gray in the CIELAB color space, a total of 9 colors to be matched are used as test color samples for illustration. It should be noted that the present invention is not limited to the color matching between the printing color and the display color, and is applicable to the color matching between color sample pairs in various color rendering methods. The colors to be matched are not limited to the 9 color centers recommended by CIE.

[0035] The method for classifying observer's color matching function of the present invention comprises the following steps:

[0036](1) build as figure 1 The shown color matching experimental device-including target color, matching color and standard observation box providing illumination source, choose a color, and the target color and matching color are composed...

Abstract

The invention relates to a method for classifying observer color matching functions. The method includes the steps that a color matching experimental device is set up and comprises a target color, a matching color and a standard observation box providing an illuminating light source, multiple colors are selected, the target color and the matching color are respectively composed of different primary color spectrums, and the illuminating light source is a sunlight source; observers are organized to perform a color matching experiment through adjusting the number of three channel primary colors of a displayer RGB; a PR650 spectral radiosity meter is used for measuring color stimulation spectrum data of the target color and the matching color on the displayer; CIE1931, CIE1964, CIE2006 and Sarkar1-8 are selected as the color matching functions of the experiment to calculate color difference of color matching of the observers, cone cell spectrum responses of the observers organized for the experiment are classified, and the observers are divided to the corresponding categories of color matching functions. The method is used for evaluating and dividing the cone cell spectrum responses of the different observers.

Description

technical field [0001] The invention relates to a method for classifying observers' color matching functions. By building a color matching experiment device, different observers are organized to conduct color matching experiments on printing colors and display colors, and the metamerism in the color matching process of the observers is checked to determine Class of different observer color matching functions. Background technique [0002] The existing color matching functions for calculating chromaticity values ​​are only CIE1931 and CIE1964 recommended by the CIE International Commission on Illumination, which represent the average cone cell response of observers with different viewing fields of view (2° and 10°). However, due to the individual differences of observers, some observers often think that the colors match, but some observers think that they do not match. This phenomenon is especially obvious for the color stimulus produced by the superposition of narrow-band pr...
