A video processing apparatus acquires audio-visual environment information that indicates an audio-visual environment of a viewer that views video. The audio-visual environment information includes information of a display size of the video that is being viewed, information of brightness around a display apparatus that displays the video, and information of a distance between the viewer and the display apparatus. The video processing apparatus corrects, depending on information indicated by the audio-visual environment information, a basic reduction amount to reduce a quantity of motion of the video that is being played back, and processes the video with use of a corrected reduction amount. In the case where the display size is large, in the case where it is dark around, or in the case where the distance from the viewer to the display apparatus is short, the reduction amount to reduce a motion is set to be large.

A rear entertainment system has a voice synthesis circuit, an OSD unit, a video camera, a DVD playback unit, a rear monitor, a navigation unit, a mixer, an IR circuit, and headphones. The voice synthesis circuit and the OSD unit receive driving information from a handle, a brake, a winker, and so on. The voice synthesis circuit presents the driving condition in an audio form, while the OSD unit presents the driving condition in a video form. The video camera takes a scene in a forward direction.
