Appeal No. 2002-0303
Application No. 08/831,872
BACKGROUND
Appellants’ invention relates to a video-signal processing device connectable to
an electronic endoscope. The device has a serial digital video signal output from the
video signal processing device to a piece of compatible external digital peripheral
equipment. An understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced below.
1. A video-signal processing device connectable to a video
processor of an electronic endoscope, comprising:
a system that feeds at least one kind of electric analog video
signal, obtained from the video processor of said electronic endoscope, to
a piece of analog peripheral equipment;
an insulation coupler, intercepting the electric analog video signal
between the video processor of said electronic endoscope and the
system, that electrically insulates all electrical connections of the video
processor of said electronic endoscope to said device;
an analog-to-digital converter that converts the electric analog
video signal into a parallel electric digital video signal; and
a parallel-to-serial converter that converts the parallel electric digital
video signal into a serial electric digital video signal, and that feeds the
serial electric digital video signal from the video-signal processing device
to a piece of compatible external digital peripheral equipment.
