A program for generating an image, the program causing a computer to function as: an object space setting section which sets an object in an object space; a vertex processing section which performs per-vertex processing; and a pixel processing section which performs per-pixel processing, wherein, when subjecting an object of a first group to predetermined processing which is implemented by a first processing and a second processing, the vertex processing section performs the first processing with a processing load lower than a processing load of the second processing, and the pixel processing section performs the second processing; and wherein, when subjecting an object of a second group differing from the first group to the predetermined processing which is implemented by a third processing and a fourth processing, the vertex processing section performs the third processing with a processing load higher than a processing load of the fourth processing, and the pixel processing section performs the fourth processing.
