Using non-standard cameras
Different non-standard cameras can support various modes and features. A camera
is considered non-standard when its video signals do not conform to one of the
internationally accepted video standards, such as CCIR, RS-170, NTSC, or PAL.
Y Non-standard cameras can support some of the following characteristics:
• Interlaced or non-interlaced mode.
R • Frame scan or line scan capabilities.
A 5 • Various resolutions.
IN 0 • Analog or digital video signals.
0 • Adjustable pixel clock frequency.
IM 2 • Asynchronous reset mode (useful when grabbing upon a trigger).
• External exposure shutter control.
L Y • Multiple taps.
E A • Varying bits per pixel.
• RGB color.
R M • Bayer filters.
• Slave or master mode (in a slave mode, the frame grabber is master while the
P 19camera is slave).
The remainder of this chapter gives you recommendations on configuring your
DCF for most of these characteristics.
You can read about triggered grabs and asynchronous reset, and user-defined
signals in the chapter Using exposures, triggers, and user-defined signals.
