摘要

PROBLEM TO BE SOLVED: To confirm the presence or absence of a defect of a read image of a color patch of color measurement object, without preparing other color patch.SOLUTION: A color patch defect determination device includes a color patch read image storage unit for storing a color patch read image, i.e., a read image of a color patch, a pixel value acquisition unit for acquiring the pixel value of the color patch read image, a pixel value distribution information calculation unit for calculating the pixel value distribution information indicating the distribution state of pixel values, based on the pixel value thus acquired, and a defect determination unit for determining the defect of the color patch read image, based on the pixel value distribution information.SELECTED DRAWING: Figure 14
