<p>In a scanning line converting operation, an image signal is processed through a system including memories (109, 110), switches (123, 124), arithmetic circuits (111, 112), an adder (113), a subtracter (114) and a switch (125). In a graphic process, coordinate data processed by a parameter generator (105) and a drawing unit (119) is subjected to a coordinate converting calculation by the arithmetic circuits (111, 112) and supplied to an address generator (108). Based on an address generated by the address generator, a texture model, which has been stored in a memory (131) under control of a CPU (104), is read out and supplied to a synthesizing circuit (118). In the synthesizing circuit, the texture model is attached to a polygon output from a drawing unit (119). <IMAGE></p> |
