Abstract
In an image forming device recognizing a specified area as a rectangular shape in an original image in which the area is specified by a frame indicated by use of a marker pen or the like, erroneous detection of a rectangular shape due to noise is prevented. Pixels having the halftone value in the image data are recognized as a frame and an area surrounded by the frame is defined by a rectangle and rectangle information thereof is provided. The size of the rectangle indicated by the rectangle information is determined, and if the size of the rectangle is smaller than a preset value, the rectangle information is eliminated as invalid information.
