-15- ABSTRACT An apparatus (10) simulates scenic translation and comprises simulator controls (64) which generate signals (18-26) corresponding to the horizontal position of a vehicle. In prior systems, a representation of a scene is merely moved with respect to an observer to achieve a change in scene content. In the inventive system a video disc storage playback unit (12) generates a raster (54) including video information (58) representing a scene to be viewed. A microprocessor (65) responsive to the simulator controls generates control signals for selecting a portion (50 or 52) of the raster corresponding to the position of the vehicle. Variable delay gates and associated circuitry (66, 68,76) responsive to the microprocessor select a portion of each line in the raster. A monitor (84) displays the selected portions, providing a simulated scene which changes in content and perspective in response to simulated scenic translation.
