COLOR CONVERSION PROCESSING APPARATUS AND COLOR CONVERSION PROCESSING METHOD

摘要

A color conversion apparatus to output image data to a printer obtains roughness data to indicate the roughness of each pixel in an image expressed by the image data, derives a reduction ratio of a color gamut in each pixel according to a roughness of each pixel in the roughness data, changes color gamut data indicating for the printer on a substantially flat surface according to the derived reduction ratio to derive color gamut data in each pixel, and then performs color conversion on each pixel in the image data using the derived color gamut data.

1. A color conversion apparatus outputting image data on an object to be reproduced to a printing unit, comprising:
a roughness data obtaining unit configured to obtain roughness data indicating a roughness of the object; a reduction ratio deriving unit configured to derive a reduction ratio of a color gamut in each pixel according to a roughness of the pixel in the obtained roughness data; a color gamut deriving unit configured to derive color gamut data to be applied to each pixel by changing color gamut data for the printing unit according to the derived reduction ratio; and a color conversion unit configured to perform color conversion on each pixel in the image data by using the derived color gamut data.
