MOTION BLUR IMAGE GENERATION DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To solve the problem that since a conventional motion blur method is provided to plot a plurality of frames for the purpose of obtaining one display frame, and to carry out their composition processing, calculation quantity is extremely large, and expensive hardware is required for performing plotting in a real time.;SOLUTION: Not only polygon data included in a current plotting object but also polygon data included in the past plotting object to be used as an after-image are inputted to a graphic engine, and the polygon data of the current plotting object are compared with the polygon data of the after-image, and as for the polygon of the after-image, whether or not the light source calculation result of the polygon of the plotting object or the polygon of another after-image is reusable is decided, and when it is decided that the light source calculation result is reusable, the light source calculation is omitted.;COPYRIGHT: (C)2007,JPO&INPIT
