Abstract:
1. A game system which executes a computer program to generate an electronic image to provide more realistic view on a display screen, comprising: means which transforms a depth value, comprising a plurality bits, of each pixel of an original image into a second depth value or an alternative second depth value, both being formed of the lower bits I to J of the depth value which are positioned lower than a most significant bit of the depth value; means which sets an alpha value of each pixel to a value corresponding to the second depth value or the alternative second depth value; means which generates the electronic image based on the set alpha value, wherein the bits I to J are an intermediate set of bits, and are below the uppermost bit and above the lowermost bit of the depth value, wherein, when the depth value is within a predetermined range, the depth value is transformed into the second depth value, and, when the depth value is outside of the predetermined range, the depth value is transformed into the alternative second depth value,
