Abstract:
1. A method of processing a plurality of source images to provide a composite image suitable for rendering as a rendered composite image, comprising the steps of: receiving the plurality of source images; and encoding the plurality of source images to thereby provide the composite image; wherein the encoding includes mapping of source image values at pixel locations in the source images to colorant control values at respective pixel locations in a spectrally-multiplexed image plane, wherein the colorant control values specify an amount of each one of a plurality of M colorants to be deposited at corresponding locations In the rendered composite Image, wherein the mapping of the pixel values from the plurality of source images is determined according to a plurality of spatial luminance distributions each of which representing the desired response of the rendered composite image to illumination thereof by a respective one of a plurality of N narrow-band illuminants, and wherein the mapping of the pixel values from the plurality of source images is calculated to cause a selected one of the source images to be recovered when the rendered composite image is subject to illumination by at least a selected one of the narrow-band illuminants.
