Abstract
A TV camera (22) generates a low level video signal which represents a sensed image pattern from an image intensifier (18). A preamplifier circuit (24) boosts the low level video signal. The preamplifier is selectively switched between feedback paths (74,76) to select the gain of the preamplifier, and between various filter paths (84,88) to select the bandwidth. Various display processing components such as a digital acquisition system (42) and video tape or video disc recorder (44) are provided to process video signals from the preamplifier circuit. A monitor (26) containing circuitry to generate synchronization signals, to adjust brightness, to adjust images aspect ratio, and to adjust image resolution is provided to convert the video signals into a man readable display. A video switch (40) selectively routes the video signals from the preamplifier to one of the display processing components and from these components to the monitor. The route, the gain, and the bandwidth are controlled by input from a console (30).
