Abstract
An α-value αPcorresponding to a Z-value of each pixel in an original image and an α-nonuniformity setting α-value a UP which is a nonuniform α-value in a virtual plane are synthesized into an α-value αP. The color ICP of the original image and the fog color CP are synthesized into a fog image, based on the α-value αP2. A plurality of α-nonuniformity setting α-values provided for the virtual planes different in nonuniformity pattern are synthesized. The nonuniformity patterns are changed depending on the virtual camera information and time information. An α-value used to synthesize the α-nonuniformity setting α-values is set based on a Z-value of each pixel in the original image. A Z-value of each pixel in the original image is used as an index number of a lookup table and the index color texture mapping is applied to a virtual object to convert the Z-value into an α-value.
