Abstract
A camera producing colour video outputs may employ an image intensifier and a monochrome CCD sensor The scene is exposed through filters F , F which may each contain stripes of subtractive primary colours alternating with clear regions. The video is decoded using waveforms derived from a memory which records the output of the sensor when imaged on, for example, primary colours such as red and blue, producing trains of pulses which identify the spatial regions of each line corresponding to the spatial areas of the pattern on the sensor produced by the colour filters F , F , in order that actual scenes can be decoded using the stored waveforms, for example using sample and hold devices. A colour interference signal is generated in matrix addition circuitry to produce a luminance signal which has stripe visibility removed from it, permitting high resolution video signals to be obtained.
