Systems for spectral multiplexing of source images to provide a composite image, for rendering the composite image, and for spectral demultiplexing the composite image to obtain a normalized color image

摘要

Methods and apparatus for spectrally-encoding plural source images (11-1...11-N) and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, and for recovering a normalized version of an encoded source image from the rendered composite image such that the recovered source image is made distinguishable as a normalized color image, by subjecting the rendered composite image to an illuminant having a predefined spectral power distribution.
