    摘要: An image processing method according to one mode of the present invention stores a threshold matrix (12) for quantization processing of input image data (20), applies mask processing to an abnormal recording element based on abnormal recording element information (10), corrects 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 performs quantization processing using a corrected threshold matrix (18).
