Glossary 61
• Camera Link.
A serial communication protocol standard designed for computer vision
applications based on the National Semiconductor interface Channel-link. It was
designed for the purpose of standardizing scientific and industrial video products
including cameras, cables and frame grabbers.
• Contiguous memory.
A block of memory occupying a single, unbroken series of addresses.
• DCF.
Digitizer configuration format . A format that defines how the video source and the
frame grabber are configured. The video source and the frame grabber are set to
the specified camera mode, which defines the format of transferred data. The DCF
can also configure the triggers, timers, and quadrature decoders.
DCF files have a . dcf extension.
• DDR3 SDRAM.
Double-data-rate type 3 synchronous dynamic random-access memory . A type of
general purpose consumer RAM. DDR3 SDRAM allows for data transfer at very
high speeds, which is important for I/O-bound functions. This type of memory
is inexpensive, high density, and very efficient as long as the data is accessed
contiguously.
• Digitizer configuration format.
See DCF .
• Dynamic range.
The range of values present in a buffer. An unsigned 8-bit buffer, for example, has
an allowable range of 0 to 255; its dynamic range can be any range within these
values.
