Abstract
Official abstract text for this publication.
Data which represents a color space is input, a dataset which represents visual uniformity in each of a plurality of color areas is acquired, and control points which indicate a control region including the plurality of color areas corresponding to the dataset are set on the color space. Then, using the control points and dataset, the color space is corrected to be shrunk.
First claim
Opening claim text (preview).
What is claimed is: 1. A color processing apparatus comprising: an input unit configured to input data which represents a color space; an acquisition unit configured to acquire a dataset which represents visual uniformity in each of a plurality of color areas, wherein the dataset comprises an elliptical curve; a setting unit configured to set, on the color space, a plurality of control points which indicate a control region; a generation unit configured to generate conversio…
