Systems for spectral multiplexing of source images including a stereogram source image to provide a composite image, for rendering the composite image, and for spectral demultiplexing of the composite image

摘要

Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. Stereogram generation techniques can be employed to provide the image content of one or more stereogram source images encoded in the composite image. When the composite image is subjected to illumination by a narrow band illuminant, an observer can identify the pattern correspondence necessary for comprehending the image content of the stereogram source image.
