<p>The video processor is housed in a box (10) with a connection socket (11) for a plug (30) with an electric connector (31), and a socket (12) for the end (61) of a lighting cable (60). The plug encloses a printed circuit (56) with three devices for adjustment of the electronic shutter clock, pixel clock and integration clock signals. Speed control pulses for the shutter integrated into the distal CCD imager are regulated by an amplifier and potentiometer. Pixel readout is synchronised by means of another amplifier and a stepped delay line. The DC level from the power supply unit (21) for integration control is set by another potentiometer.</p> |
