Abstract:
Disclosed are improved methods, systems and devices for color night vision that reduce the number of intensifiers and/or decrease noise. In some embodiments, color night vision is provided in system in which multiple spectral bands are maintained, filtered separately, and then recombined in a unique three-lens-filtering setup. An illustrative four-camera night vision system is unique in that its first three cameras separately filter different bands using a subtractive Cyan, Magenta and Yellow (CMY) color filtering-process, while its fourth camera is used to sense either additional IR illuminators or a luminance channel to increase brightness. In some embodiments, the color night vision is implemented to distinguish details of an image in low light. The unique application of the three-lens subtractive CMY filtering allows for better photon scavenging and preservation of important color information.

Claim (Index 20):
A color night vision camera, comprising:\n at least one separating mechanisms for receiving an image, wherein each of the at least one separating mechanisms is configured to be operable to separate a first frequency range of information and a second frequency range of information from the received image; one or more combining mechanism configured to be operable to combine at least two or more frequency ranges of information; a first intensifier assembly configured to be operable to produce a first frequency range channel as an output of the color night vision camera via at least one of the one or more combining mechanisms, wherein the first frequency range channel comprises an intensified first frequency range of information; a second intensifier assembly configured to be operable to produce a second frequency range channel as an input to at least one of the one or more combining mechanisms, wherein the second frequency range channel comprises an intensified second frequency range of information; a third intensifier assembly configured to be operable to produce a third frequency range channel as an input to at least one of the one or more combining mechanisms, the third frequency range channel comprises an intensified third frequency range of information, wherein the third frequency range of information corresponds to a second frequency range of information separated by one of the at least one separating mechanisms; and at least one overlay device configured to be operable to provide overlays to at least one of the one or more combining mechanisms, wherein each of the one or more combining mechanisms provides the first frequency range channel or a combined frequency range channel as an output of the color night vision camera, the combined frequency range channel includes one or more of a first, second, and third frequency range channels combined with one or more of the overlays.
