METHOD AND APPARATUS FOR THE COLOR FIDELITY DISPLAY OF A COLORMETRICALLY MEASURED LIGHT DISTRIBUTION

摘要

PURPOSE: A method for color-displaying is provided to display color distribution by a colorimetric system, while taking adaptive color deviation of human eyes into account. CONSTITUTION: A reproduction medium displays one color under the control of the reproduction medium by using an output value, a monochrome locus of the color in the reproduction medium is measured and the measured value is stored, the processing step above is repeated by each output up to all the areas of the reproduction medium to store measured value pairs of the monochrome loci, the measured value pairs are converted into a color system, a white point of the reproduction medium is decided under a conversion origin, the converted value pair is stored in a calibration data-set, one converted value pair is assigned uniquely to each output value, the measured value of the luminous intensity distribution to be reproduced is converted into the color system used for the calibration of the reproduction medium, the proper conversion origin is selected by taking the adaptive color deviation of human eyes into account in a way such that the chromatic color visually perceived in the luminous intensity distribution to be reproduced is displayed as an achromatic color even by the reproduction medium, an output value (k) corresponding to each converted measured value pair in the luminous intensity distribution to be reproduced is selected from the calibration data-set for the reproduction medium and the luminous intensity distribution is displayed, by controlling the reproduction medium by using all output values obtained in the steps above.
