ABSTRACT:
An image processing method of converting multiple-value image data into including the steps of: preparing dot pattern tables respectively for the graduated tone numbers, each of the dot pattern tables being demarcated into blocks of the dot patterns correlated with positions of pixels so that a block row constituted of two of the blocks of the dot patterns mutually adjacent is defined by a boundary in a recording-head-recording-medium relative movement direction that does not coincide with a straight line parallel to the direction, the dot patterns in each of the dot pattern tables being determined so that banding caused by characteristics of the recording elements is corrected in accordance with a correlation between each of the recording elements and surrounding elements thereof; and then selecting the dot patterns respectively for the pixels from the tables in accordance with the positions and the graduated tone values of the pixels.
