IMAGE READER AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To perform at least partial image adjustment processing even if a parameter cannot appropriately be read from an adjustment original.SOLUTION: A parameter image showing a parameter used when image adjustment processing is performed on a plurality of places in a margin area is attached to an adjustment original. A sub-parameter image showing a sub-parameter for performing at least a partial processing of the image adjustment processing using the parameter is attached in an area to which the parameter image of the margin area is below attachment. When the parameter is not stored in a parameter storage section if both data from which the parameter image is read are not totally matched, at least the partial image adjustment processing is performed by using the sub-parameter. When the parameter is stored, the sub-parameter is determined whether it is matched with at least a part of an element that the stored parameter shows. When they are determined to be not matched, a warning is displayed and the image adjustment processing is terminated.
