Abstract
A graphics processing device has an image data storing unit for storing image data, a graphic data storing unit for storing graphic data, a coordinate inputting unit for inputting coordinates, a display unit for displaying the image data and the graphic data, and a graphic operation processing unit for processing the image data and the graphic data. The graphic data are processed with reference to the image data displayed on the display unit by designating a control point. The designation of the control point is made to allow its image characteristic point recognizing section to set a predetermined region in the neighborhood of an input point inputted for the graphic operation, to recognize a shape of an image in the predetermined region, decide a characteristic point of the image corresponding to the shape of the image recognized, and to deliver the characteristic point of the image as the control point to a control point inputting unit.
