Patent ID: 7629974

Claim:
A storage medium storing a game image processing program executed by a computer of a game image processing apparatus that converts a resolution of a game image from a first resolution into a second resolution of n-times of the first resolution and outputs the game image after conversion, wherein said game image processing program causes said computer to perform: generating a high resolution image obtained by converting a low resolution image of the first resolution into said second resolution, and storing the image after conversion in a storage; comparing pixel values of an arbitrary pixel and the pixel adjacent to the arbitrary pixel in an oblique direction, for the arbitrary pixel in said low resolution image; shifting the pixel having the same pixel value obtained by comparing pixel values of an arbitrary pixel and the pixel adjacent to the arbitrary pixel, by m (1≦m≦n−1) pixels along said oblique direction of the pixel of said high resolution image corresponding to the pixel at said second resolution, then superposing the pixel on the high resolution image in a semi-transparent state, thereby updating said high resolution image; and outputting the high resolution image thus updated by the pixel shifting.
