Whether a job-lock function is enabled is determined. Whether a current mode is a mode for outputting an image of an area on an original document onto a recording paper is determined. When the job-lock function is determined to be enabled, and when the current mode is the mode for outputting the image of the part of the area of the original document on the recording paper, the image of an area larger than the part of the area is read. It is possible to improve accuracy of recognizing a copying protection pattern, and to improve security, even when density unevenness is present on a copying prevented original document.
