Title:
METHOD FOR GENERATING COUPLED LOOKUP TABLE, IMAGE PROCESSOR AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2008160306
Kind Code:
A
Abstract:
To reduce the degradation of the image quality of images to be formed while suppressing the increase of the data amount of a coupled LUT when generating one coupled LUT by coupling an LUT for color matching and an LUT for color separation.
An information processor generates the coupled LUT for performing color matching and color separation altogether on the basis of the LUT for color matching and the LUT for color separation. The input point of the coupled LUT is set such that output corresponding to the input point of the coupled LUT corresponds to the input point of the LUT for color separation.
