Abstract
A video image generator for producing a background image giving the visual appearance of an ocean on a raster type video screen. The image generating circuitry includes means for producing background patterns in successive scan frames of the raster to provide a visual appearance of forward movement. Apparent lateral movement is also provided by shifting the image horizontally. Such visual movement is provided in response to motion control signals associated with video games or the like.
