Aliasing is reduced by the image drawing method of this invention. A plurality of amounts of shift by which the drawing positions of when the RGB values of each pixel are written in a frame buffer are shifted with a precision minuter than one pixel are determined, and the RGB values are written in the respective positions in the frame buffer corresponding to the amounts of shift to overwrite an image. As shown in Figure 7, the point whose coordinates are (1.6, 1.3) is written in the pixel (1, 1) at the first image drawing (Figure 7(A)), written in the pixel (2, 1) at the second image drawing (Figure 7(B)), written in the pixel (2, 1) at the third image drawing (Figure 7(C)), and written in the pixel (1, 1) at the fourth drawing (Figure 7(D)).
