Abstract:
1. An image processing apparatus, which uses input tone data for a first color space image to generate reproduction data that express a halftone for an image, comprising: a color converter, for performing an interpolation process, for referring to a color conversion table to convert said input tone data for said first color space into tone data for a second color space; and a halftone processor for converting said tone data for said second color space into image reproduction data, by referring to a halftone table that shows the correlation of said tone data for said second color space and said image reproduction data, wherein a gamma characteristic A, for said input tone data for said first color space and an output density relative to a tone value for each brightness level of an image, corresponds to a gamma characteristic B for said halftone table and an output density relative to a tone value for each brightness level of an image.
