A three-dimensional content playback unit outputs to two or more image buffers a plurality of stereoscopic images of three-dimensional content, including a first parallax image and a second parallax image, resulting from viewing an object in a virtual three-dimensional space from different viewpoints. An interrupt request receiving unit receives an interrupt request requesting that a control menu be displayed. A control menu output unit overwrites, responsive to the acquisition of an interrupt request by the interrupt request receiving unit, a drawn image of an object in a three-dimensional space with an image of an object of the control menu drawn with parallax while moving the object of the control menu in the depth direction of the virtual three-dimensional space away from the viewpoint, regardless of the relative positions of the object of the control menu and the object in the three-dimensional space.
