摘要： A clipping processor has a first polygonal end point memory for storing two end point information of X and Y constituting a polygon and respective end point information of mapping information. The clipping processor also has a screen side generating circuit for judging whether a polygonal side crosses each of screen end points and is located inside or outside a screen based on the two end point information from the first polygonal end point memory. The clipping processor further has an intersecting point arithmetic circuit for calculating an intersecting point on the polygonal side at each of the screen end points and respective end point addresses of the mapping information at the intersecting point on the basis of data from the screen side generating circuit. The two end point information and the mapping information at the intersecting point on the polygonal side at each of the screen end points are clipped by the intersecting point arithmetic circuit and are written to the second polygonal end point memory.

摘要： An image processor has an end point memory for storing two end point information of X and Y constituting a polygon and respective end point information of internal pattern information; an outline processor for performing outline processings of address information of an outline of the polygon and the internal pattern information corresponding to the polygon on the basis of the two end point information and the respective end point information of the internal pattern information from the end point memory; an internal figure-drawing processor for calculating an address between two opposite polygonal sides calculated by the outline processor on the basis of the outline address information, the internal figure-drawing processor calculating an address of the internal pattern information corresponding to the polygonal outline; and a display for displaying image information of a figure. An image is displayed by deforming an internal pattern shown by the internal pattern information based on contour point information of a supplied figure.
