Video Controller
The Video Controller accepts analog differential video and pilot tone (sync) signals from the CCD camera. The pilot
tone signal contains sync, drive, and pixel clock data. The Video Controller converts the analog video signal to ten bits
per pixel parallel data, which it sends to the Image Processor.
The Video Controller performs Genlock control for the Workstation, anti-aliasing and anti-vignetting of the digital X-Ray
images, and creates the VLI window needed for the X-Ray Generator to perform Automatic Brightness Stabilization.
Image Processor
As its name implies, the Image Processor manipulates the digital video from the Video Controller to produce the
following effects and functions in the displayed images:
• Vertical and horizontal image reversal
• Circular blanking
• Window and level control
• Automatic sample window positioning
• Real-time image edge enhancement
• Subtraction
• Peak opacification
• Zoom and roam
• Cine interface generation
• Text and graphics for image annotation
