Abstract (en)
[origin: WO0007365A1] An imaging system using a color shutter receives signals indicative of color information in a plurality of planes together with infrared information and a signal indicative of the infrared radiation alone. The infrared radiation signal may be subtracted from the signals associated with the color planes to develop signals free of infrared radiation effects for each of the desired color planes. In addition an infrared signal is available which may have useful applications in some situations. In this way, color information color bands may be obtained without the need for an infrared filter and infrared information is retained for use in other applications if desired. In addition infrared and dark current information may be derived that can be used for dark current correction.
