| 1. A computer-readable storage medium encoded with a computer program which, when executed by a computer, causes the computer
to function as:
a glare source drawing section which draws a glare source while referring to a Z value of an original image stored in a Z
buffer to generate a first glare source image, and draws the glare source without referring to the Z value of the original
image stored in the Z buffer to generate a second glare source image;
a glare correction image generation section which performs image calculation processing including AND processing of a first
image which is an image obtained by subjecting the first glare source image to first blur processing and a second image which
is one of an image obtained by subjecting the second glare source image to second blur processing and the second glare source
image to generate a glare correction image; and
a glare expression image generation section which generates a glare expression image in which a corrected glare effect is
expressed in the original image based on the original image, the blurred image of the first glare source image, and the glare
correction image.
