An image generation system includes a first image generation section for generating images IL1 and IR1 for the left eye and the right eye, a second image generation section for generating images IL2 and IR2 for the left eye and the right eye by performing correction processing to remove perspective of images in the IL1 and IR1 at a base surface, and a stereoscopic image generation section for generating a stereoscopic image based on the IL2 and IR2. It further includes an image generation section for generating an image IL for the left eye by rendering a projection of each point of a graphic object onto a base surface BS in a projection direction linking a viewpoint position for the left eye VPL to each point of the graphic object OB, and for generating an image IR for the right eye by rendering a projection of each point of the graphic object onto the base surface BS in a projection direction linking a viewpoint position for the right eye VPL to each point of the graphic object OB, and the stereoscopic image generation section for generating a stereoscopic image based on the IL and IR.
