DENSITY CORRECTION TABLE COMPRESSOR, DENSITY CORRECTION TABLE COMPRESSING METHOD, PROGRAM, AND STORAGE MEDIUM

摘要

PPROBLEM TO BE SOLVED: To provide the technology enabling high-quality image correction to be performed with a small memory capacity. PSOLUTION: This density correction table compressor comprises: a comparison means for comparing a difference between an output pixel value of a self-nozzle to be processed, and a reference nozzle in a predetermined relationship to the self-nozzle, with a threshold set depending on an input pixel value of the self-pixel, when the input pixel value of the self-pixel is imparted from a density correction table in which the input pixel value of the self-pixel to be corrected corresponds to the output pixel value of the self-pixel; a data integration means for integrating the output pixel value of the nozzle with a difference equivalent to/below the threshold; and a table compression means for compressing the amount of the data of the density correction table by generating an index smaller in the amount of data than the output pixel value in a part, having the common output pixel value, of the density correction table.
