A photodetection device uses configurations of photodynamic proteins which exhibit a change in electrical conductivity in response to a corresponding change in incident light intensity in the presence of an applied voltage. The photodynamic proteins are coupled to an electrical conductor, a voltage source and a conductivity sensor. The photodynamic protein complex includes at least one layer of a photodynamic protein and preferably includes a multi-layered thin-film structure with each layer comprised of either a photodynamic protein or a conductive polymer or oligomer. Groups of linked photodetectors where the photodetectors have different, but overlapping, spectral response ranges are used to detect specific wavelengths of incident light. An array of these groups of linked photodetectors arranged in a predetermined spatial pattern allows detection of both colon and images. An image processing system is constructed from this array of groups of linked photodetectors by coupling the output of the array to a processing component and the output of the processing component to an output device. A dynamic adaptive camouflage system is derived from the image processing system by mounting the photodetectors and display devices on an apparatus to be camouflaged and displaying a spatially shifted image of the incident ambient light.
