Abstract
This application provides an electronic endoscope system allowing an accurate delay time corresponding to a length of an electronic scope to be set and allowing a configuration to be simplified. The electronic endoscope system is configured by connecting electronic endoscopes different in length to a processor unit and provided with a reference-delay-time generation circuit for generating a signal having a rough reference delay time and a short-delay-time generation circuit for generating a signal having a delay time shorter than the reference delay time by using a gate delay device or the like. A microcomputer in the processor unit reads delay-time-designation control data D1 and D2 from a ROM in an electronic scope, generates a delay drive clock signal by the two delay-time generation circuits in accordance with the control data D1 and D2, and executes preferable image processing in accordance with the delay signal.
