Abstract
An image processing apparatus includes an input section, and a screen processing section. The input section inputs image information. The screen processing section performs screen processing on the input image information with a threshold matrix. A plurality of threshold values are arranged in the threshold matrix so that if the threshold values are colored in an ascending order or descending order. The threshold matrix represents at least one selected from the group consisting of capital alphabets ‘A’ to ‘Z’, lower case alphabets ‘a’ to ‘z’ and numeric characters ‘0’ to ‘9.’
