Abstract
Abstract In an electronic endoscope system, a scope has a solid 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 manually operates the alteration system to perform the alteration of the peak-to-peak level of the synchronizing-signal component.

Claim 1
Independent Claim
78 words
An electronic endoscope system including a scope having an 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; and a manual setting system that manually operates said alteration system to perform the alteration of the peak-to-peak level of said synchronizing-signal component.
Claim 2
Dependent Claim
78 words
An electronic endoscope system including a scope having an 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; and a manual setting system that manually operates said alteration system to perform the alteration of the peak-to-peak level of said synchronizing-signal component.
Claim 3
Dependent Claim
37 words
An electronic endoscope system as set forth in claim 1 , wherein said manual setting system is constituted such that the alteration of the peak-to-peak level of said synchronizing-signal component is stepwise performed by said alteration system.
Claim 4
Dependent Claim
51 words
An electronic endoscope system as set forth in claim 1 , wherein said alteration system comprises a multiplier, and said manual setting system comprises a manual digital switch that produces code data, a multiplier-factor of said multiplier being altered in accordance with the code data produced by said manual digital switch.
Claim 5
Dependent Claim
83 words
An electronic endoscope system as set forth in claim 1 , wherein said alteration system comprises a voltage-controlled amplifier, an amplification factor of which is altered in accordance with a level of a voltage signal applied thereto, and said manual setting system comprises a manual digital switch that produces code data, and a voltage signal generator that generates the voltage signal such that the level of said voltage signal is altered in accordance with the code data produced by said manual digital switch.
Claim 6
Dependent Claim
95 words
An electronic endoscope system as set forth in claim 1 , wherein said alteration system comprises a voltage-controlled amplifier, an amplification factor of which is altered in accordance with a level of a voltage signal applied thereto, and said manual setting system comprises a storage system that stores voltage data, a voltage signal generator that generates the voltage signal such that the level of said voltage signal is altered in accordance with the voltage data stored in said storage system, and a manual-altering system that manually alters the voltage data stored in said storage system.
Claim 7
Dependent Claim
27 words
An electronic endoscope system as set forth in claim 4 , wherein said storage system comprises a non-volatile memory, such as an electrically erasable programmable read-only memory.
