Abstract
Official abstract text for this publication.
There is provided a color processing apparatus comprising: a calculation unit configured to calculate, for each of a plurality of light sources, a first colorimetric value that is obtained by measuring a color having a spectral reflectance indicated by spectral reflectance information under the light source; a mapping unit configured to obtain, for each of the plurality of light sources, a second colorimetric value by mapping the first colorimetric value of the light source within a gamut under the light source; a color separation unit configured to obtain the output information from a plurality of the second colorimetric values, by adjusting the output information such that an error between a colorimetric value obtained by measuring a color output by the image output apparatus according to the output information under each of the light sources and the second colorimetric value for the light source is minimized.
First claim
Opening claim text (preview).
What is claimed is: 1. A color processing apparatus that calculates, from a spectral image having spectral reflectance information that indicates spectral characteristics of a color of each pixel of the spectral image, output information that indicates an intensity of each of a plurality of color components that an image output apparatus uses for outputting the spectral image, the color processing apparatus comprising: an acquisition unit configured to acquire the spectral image;…
