Patent ID: 8576297

Claim:
A data processing device for rendering a color image comprising: processing circuitry configured to: receive data associated with a first set of spectral components of light received from a first illumination event of a scene, wherein the scene is illuminated with light from a first illumination source with an unknown spectral distribution; receive data associated with a second set of spectral components of light received from a second illumination event of the scene, wherein the scene is illuminated with light from a second illumination device having a known spectral distribution during the second illumination event, and render a color image of the scene based at least in part on the spectral components of light received from the first and second illumination events of the scene, wherein the light from the first illumination event is temporally separate from the light from the second illumination event, and wherein the scene is illuminated with substantially no light from the second illumination device during the first illumination event and the scene is illuminated with substantially no light from the first illumination source during the second illumination event.
