Abstract
An image processing system processes light conveying visual pattern information represented by individual light rays. The system includes an optical assembly having an input surface and an output surface. The input and output surfaces define a plurality of input and output positions, respectively, for the light rays to enter and exit, respectively, the assembly. The assembly includes a light-shifting apparatus operable so that a respective one of the light rays entering a respective one of the input positions is selectively shiftable by the apparatus in a first direction and, subsequently, in a second direction angled with respect to the first direction from a preceding one to another of the output positions. The assembly is further operable so that following each shifting operation, a respective one of the light rays transmitted by the assembly from an arbitrarily selected one of the output positions is solely derived from the light received from a single one of the input positions.
