A virtual camera for displaying characters to be imaged on a monitor can be readily set. In the present program, a virtual camera and imaging space are set in a virtual game space. A plurality of characters are arranged in the virtual game space. A controller determines whether or not the plurality of characters are positioned inside the imaging space. At least one option among the viewing angle of the virtual camera and the position of the virtual camera is modified. Therefore, when any single character among a plurality of characters is positioned outside the imaging space, the character positioned outside the imaging space is positioned inside the imaging space. The plurality of characters are displayed on the image display unit.
