Abstract
In an image processor, a storage device stores matrix patterns for changing dot area ratio according to gradation level. When a gradation image is reproduced, a pattern is read by pointing X and Y addresses to generate a pattern image in correspondence to gradation data of color components in a color image. As to a pattern stored in the storage device, X address and/or Y address can be converted for changing reading order of the pattern. For example, when the gradation image is reproduced, the same pattern is used for gradation data of two color components.
