• Manufacturer Part Number: NIPCI-1411
• Description: Single-Channel Color or Monochrome Image Acquisition
• Manufacturer: NI [National Instruments Corporation]

Hardware
PCI Interface
The PCI bus is the electrical interface for both the NI PCI-1411 and
NI PXI-1411. The National Instruments custom MITE ASIC for
interfacing to the PCI bus offers the highest image acquisition
performance available. The MITE ASIC can transfer data at a
maximum sustained rate of 100 Mbytes/s in master mode to
maximize the use of the available PCI bandwidth.
Onboard Memory
The NI 1411 Series has 16 MB of onboard memory, useful for
temporary storage of images being transferred to the PCI bus.
Trigger and Strobe
You can use the digital I/O line as an input to trigger image
acquisition or as an output to control solenoids, solid-state relays,
or strobes.
Programmable Gain and Offset
The NI 1411 Series has programmable gain and offset circuitry for
optimizing the input signal range.
I/O Connector and Cabling
Two external BNC connectors are used for the video source and
digital I/O line. Each product shipment includes a 2 m BNC cable.
Applications
The NI 1411 devices offer machine vision developers real-time
color conversion of NTSC, PAL, and S-Video formats to the hue,

saturation, and luminance (HSL) image planes. Because the hue
plane is effective for analyzing images in which shadows and
lighting gradients are present, the NI 1411 Series makes inspection
systems more reliable. With these devices, industrial inspection
and scientific imaging developers can increase the reliability and
performance of numerous applications, including inspecting light
emitting diodes (LEDs), fabric and textiles, color paint and powder,
pharmaceutical blister packs, and difficult to light applications.
Color Pattern Matching
Use color pattern matching to locate quickly known reference
patterns, or fiducials, in a color image. With color pattern matching,
you create a model or template of an object. The search tool first
scans the image to match the color distribution, then scores the
match for shape. The score relates to how closely the model
matches the pattern found. You should use color pattern matching
to locate reference patterns that the color and spatial information in
the pattern fully describe. Color can often simplify a monochrome
problem by improving contrast or separation.
