Abstract
A video-signal processing device connectable to an electronic endoscope capable of outputting a component-type electric analog color video signal. An analog-to-digital converter converts video-signal components of the component-type video signal into parallel digital color video-signal components. A color-conversion digital matrix circuit produces a parallel digital luminance signal-component, and two kinds of parallel digital color-difference signal-components based on the parallel digital color video-signal-components. A parallel-to-serial converter converts the luminance signal-component and digital color-difference signal-components into serial digital color video-signal-components. The electric analog video signal outputted from the electronic endoscope is fed outside the device as the serial electric digital video signal.
