Abstract

A handheld projector is provided with an image stabilization system that acts to reduce (or even eliminate) unwanted motion of the projected image due to unintended movement of the projector. In certain preferred embodiments, a solid-state motion sensor provides input to an image stabilization system that computes a corrective signal. In embodiments having optical image stabilization, the corrective signal is supplied to a mechanical actuator that moves one or more optical elements within the projector. Other embodiments have electronic image stabilization. In these embodiments, the corrective signal from the image stabilization system is used by the image generator to shift the image so as to compensate for movement of the projector.
