Abstract
Official abstract text for this publication.
An image processing apparatus converts first color values in a first color space to second color values in a second color space for an objective color. If the objective color is not within a color reproduction space of an outputting device, the searching unit searches for a set of color values as base color values in the color reproduction space so that the set of color values minimizes a value of the color difference formula for the first color values. As the second color values, the searching unit determines a set of color values in a predetermine neighbor space of the base color values so that the determined set of color values minimizes a difference between property values on a color property of which the allowed color difference is smallest among the allowed color differences at the first color values.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing apparatus converting first color values in a first color space to second color values in a second color space for an objective color, comprising: a color converting unit configured to calculate the second color values on the basis of the first color values using a color difference formula that evaluates a color difference between two sets of color values in a coordinate system of plural color properties that at least include brightness;…
