摘要

PROBLEM TO BE SOLVED: To appropriately detect an image portion where image quality change in a specific direction has occurred even if the image portion is short in directions other than the specific direction.SOLUTION: An image quality change detection device comprises image quality change detection means for detecting an image change in a specific direction in an image created by an image forming device on the basis of a distribution information in the specific direction indicating a distribution of image data of the image created by the image forming device in the specific direction. The image quality change detection means detects the image quality change in the specified direction on the basis of the distribution information in the specific direction for every more than two image areas that can be obtained by dividing the image in a direction crossing or orthogonal to the specific direction.SELECTED DRAWING: Figure 3
