ABSTRACT:
A projector assembly includes a multi-pixel frame projector that sequentially projects each pixel making up a frame to a viewing surface, a movement detector coupled to the projector to detect a physical movement of the projector, and a movement compensator coupled to the projector, the movement compensator operable to transmit a correction signal to the projector, the correction signal capable of causing the projector to compensate for the detected movement.
