In an exemplary image generation system, a virtual camera is set in accordance with a position and an orientation of an object in a virtual space. While a predetermined operation is being performed, an orientation of a display device is detected by using an angular velocity sensor provided in the display device, and an orientation of the virtual camera is changed based on the detected orientation. When the predetermined operation is not performed, the virtual camera is positioned based on an original orientation which is determined in accordance with the position and the orientation of the object. |
