For machine vision and scientific imaging developers who need
to acquire high-resolution, measurement-quality images from
standard and nonstandard cameras and sensors, the NI 1409
image acquisition hardware offers quick and easy configuration.
NI 1409 devices have high-resolution, 10-bit digitization for
cameras and sensors that offer 60 dB dynamic range. In addition,
you can easily configure the NI 1409 Series to work with standard
monochrome cameras (RS-170 or CCIR), slow or variable rate
pixel clock cameras, double-speed progressive scan cameras, and
analog line-scan cameras.
Many high-resolution analog mono-
chrome cameras have dynamic range
greater than 48 dB, which means that
the camera has resolution capabilities
greater than 8-bit or 256 gray scales.
For these high-resolution cameras,
you should use an image acquisition
device that offers comparable or
greater resolution. The NI 1409 Series

works with the highest quality monochrome cameras and
delivers up to 60 dB of dynamic range, which corresponds to
10 bits or 1,024 gray scales. With NI 1409 devices, you have the
option to acquire in 8-bit or 10-bit mode at very high rates, such
as 60 frames/s with double-speed progressive scan cameras.
Measurement-Quality
Image Acquisition with Calibration
NI 1409 devices are gain calibrated and delivered with a
calibration certificate. Calibration ensures repeatable, consistent
image acquisition for your machine vision and scientific Interchange Cameras with NI-IMAQ
imaging applications.
NI-IMAQ driver software for image acquisition can scale between
many types of cameras and acquisition methods. With NI-IMAQ,
you can begin by using a low-cost RS-170 camera and image
acquisition device and then upgrade to a faster, higher-resolution
camera and acquisition hardware with minimal software changes.
Because NI-IMAQ driver software uses one set of function
calls for a wide variety of cameras, there is no need to rewrite
your software.
Variable Scan and Nonstandard Video
With NI 1409 devices, you can acquire images from nonstandard
video, such as analog line-scan and variable-scan devices with
pixel clocks that range from 2 to 40 MHz. The NI 1409 devices
work with double-speed (60 frames/s) progressive scan or
noninterlaced monochrome cameras from vendors such as
Sony and JAI.

Quick and Easy Camera Configuration
DAQ Synchronization

NI-IMAQ. This utility is an interactive tool for setting the camera

ratio, and antichrominance filter. Use this interactive utility to set Trigger Control and Mapping Circuitry
up acquisition from noninterlaced progressive-scan cameras and
to create your own camera configurations for nonstandard video.
Use the external lock feature to set variable-scan acquisition for
microscopes and other sources that generate their own pixel
clock and horizontal and vertical synchronization signals.
The trigger control and mapping circuitry routes, monitors, and
drives the external and RTSI or PXI trigger bus lines. You can
configure each of these lines to start or stop acquisition on a rising
or falling edge, or use each line as digital I/O. You can also map
the lines to onboard status values (CSYNC, Acquisition in
Progress, and Acquisition Complete).
Image Acquisition Performance Gains
with Partial Image Scanning
Antichrominance and Lowpass Filter
For improved throughput and processing bandwidth, the
acquisition and ROI control circuitry monitors the incoming video
signal and routes the active pixels to the FIFO. In addition to being
able to digitize an entire frame, an NI 1409 can perform pixel and
line scaling (decimation) and ROI acquisition. With pixel and line
scaling, multiples (2,4,8) of pixels and/or lines can be transferred
to the PCI bus. Using ROI acquisition, you select an area in the
acquisition window that will be transferred to the PCI bus.
NI 1409 devices have an antichrominance filter, which can remove
chrominance information from a color video signal. There are two
software selectable antichrominance filters – one for NTSC color
-coded signals (a 3.58 MHz notch filter), and another for PAL color
-coded signals (a 4.43 MHz notch filter). Use the lowpass filter at
9 MHz to remove unwanted noise.
10-Bit A/D and Look-Up Table (LUT)
An A/D converter performs the image digitization, the result of
which passes to a 1,024 by 10 RAM LUT. You can configure the
LUT to implement simple imaging operations, such as gamma
manipulation, contrast enhancement, data inversion, or any
nonlinear transfer function.
Hardware
PCI Interface
The PCI bus is the electrical interface for both NI PCI-1409 and
NI PXI-1409. The PCI interface, implemented with the National
Instruments MITE ASIC, can transfer data at a maximum
sustained rate of 100 Mbytes/s in master mode to maximize the Programmable Gain and Offset
use of the available bandwidth. The interface logic ensures that
the NI 1409 meets the loading, driving, and timing requirements
of the PCI specification.
The NI 1409 has programmable gain and offset circuitry for
optimizing the input signal range.
VCR Circuitry
Scatter-Gather DMA Controllers
Because many commercial and home VCRs have noisy
synchronization signals or no synchronization at all, VCRs are
difficult to use with most image acquisition hardware. However,
with its built-in circuitry and logic for handling video signals from
VCRs, the NI 1409 can acquire monochrome images from VCRs.
An NI 1409 has three independent onboard DMA controllers. The
DMA controllers can transfer data between the Host memory and
the onboard FIFO via the PCI bus. Each of these controllers
performs scatter-gather DMA, which means the DMA controller
can reconfigure on the fly, and thus perform continuous image
transfers to either contiguous or fragmented buffers.
Digital I/O
The NI 1409 Series includes four general-purpose digital
input/output lines for general-purpose triggering and pulse
generation capabilities. In addition, each NI 1409 includes four
digital output lines for lighting, shutter, camera control, and
pulse generation.
Onboard Memory
An NI 1409 has 16 MB of onboard memory used to temporarily
store the image being transferred to the PCI bus. With 16 MB,
you can buffer large images during image acquisition.
