Color image processing apparatus which reduces the amount of color materials consumed that are used to form a color image with reference to an index with high utility

摘要

The present invention provides a color image processing apparatus which reduces the amount of color materials consumed that are used to form a color image with reference to an index with high utility. To accomplish this, a color image forming apparatus of the present invention is a color image processing apparatus which applies image processing to image data of an input color image, and outputs the processed image data, and which changes tone values of respective colors of the color image, so that a conversion result obtained when image data of the color image are converted into amounts of color materials becomes an amount based on a reference conversion result, the reference conversion result being obtained when the image data are color-converted by a predetermined color conversion method and the converted data is further converted into an amount of a color material.

主权项

1. A color image processing apparatus, which applies image processing to image data of an input color image, and outputs the processed image data, comprising:
a conversion unit configured to convert image data of the color image into a first color material amount, and to convert the image data into a second color material amount which is less than the first color material amount by a predetermined color conversion method; a change unit configured to change the first color material amount based on the second color material amount obtained by the conversion unit; and a reconversion unit configured to reconvert the first color material amount changed by the change unit into image data of the color image.
