<p><P>PROBLEM TO BE SOLVED: To provide an image generation system, a program and an information storage medium in which jaggy is removed with a little processing load. <P>SOLUTION: Coordinates of a primitive point of an object after perspective transformation are varied to remove jaggy so that the coordinates of the primitive point are different between the last frame and the present frame. The coordinates of the primitive point are varied to be (X1, Y1) in the first frame, (X2, Y2) in the second frame, (X3, Y3) in the third frame, (X1, Y1) in the fourth frame and the like. All X1-X3 become different values and all Y1-Y3 become different values as well. As (X1, Y1) to (X3, Y3), coordinates of apexes of a triangle (N-angle shape) including the primitive point before the coordinate variation are used. A range of the coordinate variation is made to be less than one pixel. With respect to an object (character or the like) not to apply the perspective transformation, coordinate variation processing is omitted. <P>COPYRIGHT: (C)2004,JPO</p> |
