Original Abstract Submitted

there is a possibility that the accuracy of color adjustment decreases due to high-frequency density unevenness on a test chart that is used in a case where sensor reading characteristics are obtained. the present disclosure solves this by correction processing (generating a correction table for sensor shading correction processing) of a reading sensor configuring a scan unit after removing high-frequency density unevenness in advance by performing color adjustment processing (head shading correction processing).
