Claim Text:
1. A projection display device, comprising: an electromagnetic radiation generation unit configured to generate radiation; an image generation unit configured to receive a control signal and modulate the radiation based on the control signal such that an image is generated; a beam-splitter unit configured to encode the image, wherein at least one optical element in the beam-splitter unit is manipulated to split the image into a plurality of components, wherein the plurality of components correspond to respective ranges of wavelengths of radiation associated with the image, and wherein the beam-splitter unit is further configured to scramble the plurality of components into a scrambled image; a projection unit configured to project the scrambled image onto a display surface; and an encoder unit configured to encode a marker into at least one pixel of the scrambled image, wherein the marker identifies the at least one pixel as being associated with the scrambled image.
