SCOPE
This is a high level theory of operation overview of the Synergy
UHD4
Camera Control Unit.
3.2
GENERAL DESIGN GOALS
Essential Performance
Should all else fail, it is essential that the camera system make a viable color image on
the surgical monitor. This is without undue interruption in image quality or disruption to
the surgical procedure due to a malfunction.
In this regard, the signal path from the image sensors to the video output can operate
independently of any software or microprocessor functionality. This also includes control
and operation of the integrated LED Illuminator.
Additional goals are:
A camera system optimized for endoscopic surgery
A synergy of high definition camera, LED light source, and image management
functionality
High quality and low noise video images
Ease of operation
Versatility for various procedures and environments
Design stability
The following design features are incorporated to achieve these goals:
Camera heads with three-chip image sensors and prism as well as camera
heads with a single-chip image sensor
Powerful digital signal processing to enhance image quality
No unit-to-unit adjustments or calibrations
Interchangeable camera heads without adjustment
Digital differential signaling to and from camera head
Electrical isolation and safety independent of camera head
