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.
A method of processing a plurality of source images, comprising the steps of:
An imaging system, comprising:
A system for spectral multiplexing of plural source images, comprising a spectral multiplexer for receiving image data representative of a plurality of source images, the plurality including at least one stereogram source image, and for processing the image data to encode the plurality of source images into a composite image data signal, wherein values representative of each stereogram source image pixel are mapped to a corresponding pixel value in a respective colorant image plane.
A system for rendering a composite image that includes encoded therein a stereogram source image, comprising an image recording device for receiving the composite image in the form of a composite image data file and for rendering the corresponding composite image as a rendered composite image in a plurality of narrow band colorants on a substrate.
A system for spectral demultiplexing of a rendered composite image having encoded therein a plurality of source images, the plurality including a stereogram source image, comprising a demultiplexer for subjecting the rendered composite image to illumination by a narrow band illuminant having a selected spectral power distribution, such that the encoded stereogram source image is made distinguishable.
