<p>A game machine of an electronic device provided with an image processing device having, a parameter registers (60, 70) and matrix computing circuits (66, 76) which output conversion processing signals necessary for conversion processing of image information stored in VRAMs (24a, 24b), switching circuits (77a, 77b) which switch the conversion processing signals selectively according to a coefficient k preset for every picture element and output one of them, a circuit (65) for performing product-sum operation for generating the read addresses corresponding to the picture information which are converted according to the conversion processing signals, and a VRAM access circuit (78). By virtue of such an image processing device, image data of various split screens including window display can be generated, while the increase of the load of a CPU and the increase of the capacity of an image memory are suppressed. <IMAGE></p> |
