ABSTRACT:
Translation handles are set on vertices of a conversion source image frame by a mouse. Frame move processing, enlargement/reduction processing, rotation processing, and deforming processing are performed in accordance with the number and positions of the set translation handles. The image within the frame is operated in accordance with the shape of the conversion source image frame, and the operated image is displayed within the conversion destination image frame. In geometric conversion which requires enlargement/reduction and rotation and preserves parallelism of lines, image conversion is performed by one processing including addition instructions and not including multiplication and division calculations.
