Overview
For low-cost analog color image acquisition, National Instruments
offers the PCI-1405, which acquires analog video input from
standard color or monochrome cameras. The NI PCI-1405 comes
with easy-to-use image acquisition driver software which can
acquire, save and display images. Unlike multimedia “frame
grabbers”, the PCI-1405 features increased image processing
throughput, such as partial image acquisition with programmable
region of interest.
(region of interest) feature. You can configure the size of the acquired
image using MAX, or use the ROI tools in the NI-IMAQ driver
software to transfer only a subset of the image to PC memory for
processing. Partial image scanning results in fewer pixels to process.
For example, using partial image scanning, you can reduce a 640 by
480 image to a 400 by 400 image and increase your processing speed
by operating on 48 percent fewer pixels.
Hardware
PCI Interface
The PCI bus is the electrical interface for the PCI-1405. 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 MB/s in master mode to maximize the use of the available
PCI bandwidth.
Easy-to-Use Driver Software
National Instruments NI-IMAQ driver level software offers the most
comprehensive software interface for image acquisition. NI-IMAQ is
included with the PCI-1405 board, as will as NI Measurement &
Automation Explorer (MAX) for easy configuration of cameras.
Using NI-IMAQ, you can quickly and easily acquire, save, and display
images without low-level programming. You can program your
image acquisition application in LabVIEW, LabWindows/CVI, and
Measurement Studio. In addition, NI-IMAQ controls the PCI-1405
digital I/O line.
Onboard Memory
The PCI-1405 has 16 MB of onboard memory, useful for temporary
storage of images being transferred to the PCI bus.
Performance Gains with
Partial Image Acquisition
The PCI-1405 includes features that improve overall image
acquisition and image processing speed. You can choose to acquire
only a portion of the image using the onboard programmable ROI
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.
