Stereoscopic image generator configured to take images of a virtual three-dimensional space in which an object is located, with a virtual camera, and to generate a stereoscopic image that is composed of an image for a left eye and an image for a right eye between which a disparity is provided, and display controller for causing a display section to display the stereoscopic image generated by the stereoscopic image generator, are provided. In generating the stereoscopic image, the stereoscopic image generator performs correction of decreasing a disparity of the object.
