Overview and Applications
For high-quality analog color image acquisition at an affordable
price, National Instruments offers the NI 1411 Series, which
consists of PCI and PXI plug-in image acquisition devices that
accept analog video input from standard color or monochrome
cameras. These devices come with easy-to-use image acquisition
driver software. Unlike multimedia “frame grabbers”, the NI 1411
In addition, NI-IMAQ controls the NI
1411 digital I/O line.

Performance Gains with
Partial Image Acquisition
The NI 1411 Series includes features
that improve overall image acquisition
and image processing speed. You can

Series features increased image processing throughput, such as
on-the-fly color conversion to HSL and partial image acquisition
with programmable region of interest.

Real-Time Color Conversion
Real-time color conversion is especially useful for high-speed color
matching in industrial or scientific applications, even in varying
illumination. An example of HSL in action is using color to inspect
the presence of an object even though there are shadows and/or
reflections. Lighting variations do not affect the image (hue). Use
the powerful color matching functions in IMAQ Vision to locate
objects quickly and accurately with the onboard HSL conversion.
programmable ROI feature. You can configure the size of the
acquired image using Measurement & Automation Explorer, 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.
Easy-to-Use Driver Software
National Instruments NI-IMAQ driver level software offers the
most comprehensive software interface for image acquisition.
NI 1411 Series devices are shipped with the NI-IMAQ image
acquisition driver software and National Instruments
Measurement & Automation Explorer for easy configuration of
NTSC and PAL color cameras. Using NI-IMAQ, you can quickly and
easily start your application without having to program at the
register level. You can program your image acquisition application
in LabVIEW, LabWindows/CVI, and Measurement Studio.
Color Image Acquisition Performance Gains
with Onboard Decimation
Onboard decimation also provides image acquisition and
processing performance gains by allowing onboard scaling or
decimating of the image without using the PC processor. Onboard
decimation scales the image by removing every second, fourth, or
eighth pixel (powers of two only). By reducing the number of pixels
(decimation) on the IMAQ board, the system has fewer pixels to
process with the PC processor. If you remove every other pixel
using onboard decimation, the image size decreases by
50 percent, which speeds up your processing.
