IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide an imaging technique that can perform image correction and is high in document reproducibility without being affected by a way to place a document and a camera position and also without being affected by color of a document sheet and fragmentation in corners.SOLUTION: A positioning symbol is printed in a document sheet when imaging of a document is performed by a digital camera or a portable phone with a camera such as a smart phone. By performing image processing using this positioning symbol as reference, image correction (trapezoid correction) can be performed, and the image processing that is high in document reproducibility can be performed without being affected by color of the document sheet and fragmentation in corners.
