COMPUTER PROGRAM, IMAGE PROCESSING APPARATUS, AND METHOD

摘要

A CPU (21) of a PC (2) identifies a first attribute pixel, which is a pixel having a color value included in a color range of a background color (step S63). The CPU identifies a second attribute pixel, which is a pixel having a color value included in a dark color range (step S57). The CPU registers, in a three-dimensional table, a per block average that represents color values of a plurality of pixels included in a divided block, as a posterization candidate color (step S93). The CPU replaces a color value of a third attribute pixel with a target color, which is the posterization candidate color closest to the color value of the third attribute pixel (step S111).
