Abstract
A system and method for masking images in a multi-projector system, including: converting, using signal processors associated with at least two projectors, at least two independent input video signals into at least two independent signals for masked images, each masked image having an image region and a region of attenuated brightness comprising a mask having substantially no brightness, wherein a mask of one masked image interfaces in a composite image with an image region of another masked image; independently projecting the at least two masked images via the at least two projectors to a common location to form the composite image, such that the at least two masked images are at least partially superimposed; and gradually attenuating brightness in a spatial manner adjacent to a boundary of a mask of at least one of the masked images.
