ABSTRACT:
In order to enhance the quality of image after removing a noise from image data obtained by scanning an original document, an MFP is provided with a scanning portion to obtain the image data by scanning the original document, a noise detection processing portion to detect a noise from the obtained image data, a dot region detecting portion to detect a region of dots from the obtained image data, and a copy correction processing portion to substitute a noise region with a substitution region that is located in the vicinity of the noise region and that is of the same size as the noise region if a region in the vicinity of the noise region including the noise detected by the noise detection processing portion is included in the region of dots detected by the dot region detecting portion.
