Image processing apparatus and method for discriminating an original having a predetermined pattern
An apparatus and method for processing images, which can discriminate a specific original image from other images with high accuracy. The apparatus includes a first judgment unit for judging whether image data includes data corresponding to image information that is difficult for human eyes to perceive, a second judgment unit for judging whether the image data includes data corresponding to line information arranged such that the line information overlaps image information that is difficult for human eyes to perceive, and a discrimination unit for discriminating whether or not the image data corresponds to a specific image, based on a judgment result of the first judgment unit and a judgment result of the second judgment unit. The method includes corresponding steps to perform these functions.
