Abstract
An image processing method includes: storing a threshold matrix for quantization processing of input image data, applying mask processing to an abnormal recording element based on abnormal recording element information, correcting a correspondence relationship between a recording element and a threshold such that processing of a pixel to be formed by the abnormal recording element subjected to mask processing is excluded and the continuity of a pattern of the threshold matrix is maintained, and performing quantization processing using a corrected threshold matrix.
