Electronic endoscope system
First Claim
1. An electronic endoscope system including a scope having a solid-state image sensor provided at a distal end thereof to generate image-pixel signals, and an image-signal processing unit that produces a video signal based on the image-pixel signals, which system comprises:
- an alteration system that alters a peak-to-peak level of a synchronizing-signal component of said video signal;
an manual setting system that manually operates said alteration system to perform the alteration of the peak-to-peak level of said synchronizing-signal component;
an indicator system that indicates a degree of the alteration of the peak-to-peak level of said synchronizing-signal component during the operation of said manual setting system; and
an output terminal that outputs said synchronizing-signal component having the peak-to-peak level defined by said alteration system.

Abstract
In an electronic endoscope system, a scope has a solid-state image sensor provided at a distal end thereof to generate image-pixel signals. An image-signal processing unit produces a video signal based on the image-pixel signals. An alteration system alters a peak-to-peak level of a synchronizing-signal component of the video signal. An manual setting system operates the alteration system to perform the alteration of the level of the synchronizing-signal component. An indicator system indicates the degree of alteration to the level of the synchronizing-signal component during the operation of the manual setting system.
