Introduction  
This chapter describes the NI PCI-1405 (NI 1405) and the software  
programming choices.  
About the NI 1405  
The NI 1405 is a PCI monochrome and color image acquisition device that  
supports a diverse range of analog cameras from many camera companies.  
The NI 1405 acquires images in real time and can store these images in  
onboard frame memory or transfer these images directly to system  
memory.  
The NI 1405 is easy to configure, which allows you to begin acquiring  
images quickly. The NI 1405 ships with NI Vision Acquisition Software,  
which includes NI-IMAQ, the National Instruments driver software  
you can use to directly control the NI 1405 and other National Instruments  
image acquisition hardware products. Using NI-IMAQ, you can quickly  
and easily start your applications without having to program the device at  
the register level.  
The NI 1405 features a precision color analog video decoder ideal  
for industrial and scientific environments. The NI 1405 supports  
both NTSC and PAL color standards as well as the RS-170 and CCIR  
monochrome standards. The NI 1405 also provides one external  
input/output (I/O) line that you can use as a trigger or digital I/O line. If you  
require more advanced triggering or digital I/O lines, you can use the  
NI 1405 and NI-IMAQ with the National Instruments data acquisition

Introduction  
Software Overview  
Programming the NI 1405 requires the NI-IMAQ driver software for  
controlling the hardware. National Instruments also offers the following  
application software packages for analyzing and processing your acquired  
images:  
Vision Builder for Automated Inspection (AI)—Allows you to  
configure solutions for common inspection tasks.  
Vision Development Module—Provides customized control over  
hardware and algorithms.  
The following sections provide an overview of the driver software and  
application software. For detailed information about individual software  
packages, refer to the documentation specific to the package.  
NI-IMAQ Driver Software  
The NI 1405 ships with NI Vision Acquisition Software, which includes  
the NI-IMAQ driver software. NI-IMAQ has an extensive library of  
functions—such as routines for video configuration, continuous and  
single-shot image acquisition, memory buffer allocation, trigger control,  
and device configuration—you can call from your application development  
between the computer and the image acquisition device, such as  
programming interrupts and camera control.  
NI-IMAQ performs all functions required for acquiring and saving images  
but does not perform image analysis. For image analysis functionality, refer  
to the National Instruments Application Software section of this chapter.  
NI-IMAQ is also the interface path between the NI 1405 and LabVIEW,  
LabWindows/CVI, or a text-based programming environment. The  
NI-IMAQ software kit includes a series of image acquisition libraries  
for LabVIEW, LabWindows/CVI, and Measurement Studio, which  
contains libraries for Microsoft Visual Basic.  
NI-IMAQ features both high-level and low-level functions. Examples  
of high-level functions include the sequences to acquire images in  
multi-buffer, single-shot, or continuous mode. An example of a low-level  
function is configuring an image sequence, which requires advanced  
understanding of the image acquisition device and image acquisition.

Hardware Overview  
Video Acquisition  
Video Decoder  
The NI 1405 can acquire analog color video in a variety of modes and then  
store the images in the onboard SDRAM memory or transfer the images  
directly to PCI system memory.  
The NI 1405 supports NTSC and PAL video standards in composite  
format. The onboard video decoder converts the incoming video signal to  
red, green, and blue (RGB) data.  
The video decoder allows you to control numerous parameters to optimize  
an acquisition. You can independently adjust parameters, such as analog  
input range, brightness, contrast, saturation, or frequency range, which is  
controlled by different filters. Refer to the Measurement & Automation  
Explorer Help for NI-IMAQ, which is installed with NI-IMAQ, for a  
complete description of the NI 1405 video parameters.  
The video decoder also strips out all necessary clock and synchronization  
signals included in the video signal and controls the acquisition conditions  
automatically. High-quality circuitry can generate the synchronization  
signals from poor timing signals. This allows you to acquire from, for  
example, a video cassette recorder (VCR).  
SDRAM  
The NI 1405 has 16 MB of onboard high-speed synchronous dynamic  
RAM (SDRAM). The NI 1405 can use the onboard RAM as a first-in  
first-out (FIFO) buffer, transferring the image data as it is acquired or  
acquiring the image data into SDRAM and holding it for later transfer  
to main memory.  
Trigger Control and Mapping Circuitry  
The trigger control monitors and drives the external trigger line. You can  
configure this line to start an acquisition on a rising or falling edge and  
drive the line asserted or unasserted, similar to a digital I/O line. You can  
also map many of the NI 1405 status signals to this trigger line and program  
the trigger line in polarity and direction.

Chapter 2  
Hardware Overview  
Acquisition and ROI Circuitry  
The acquisition and region-of-interest (ROI) circuitry monitors the  
incoming video signals and routes the active pixels to the SDRAM  
memory. The NI 1405 can perform an ROI acquisition on all video lines  
and frames. In an ROI acquisition, you select an area within the acquisition  
window to transfer to the PCI bus.  
Scatter-Gather DMA Controllers  
The NI 1405 uses three independent onboard direct memory access (DMA)  
controllers. The DMA controllers transfer data between the onboard  
SDRAM memory buffers and the PCI bus. Each of these controllers  
supports scatter-gather DMA, which allows the DMA controller to  
reconfigure on-the-fly. Thus, the NI 1405 can perform continuous image  
transfers directly to either contiguous or fragmented memory buffers.  
Bus Master PCI Interface  
The NI 1405 implements the PCI interface with a National Instruments  
custom application-specific integrated circuit (ASIC), the PCI MITE. The  
PCI interface can transfer data at a maximum rate of 132 Mbytes/s in  
bus master mode. The NI 1405 can generate 8-, 16-, and 32-bit memory  
read and write cycles, both single and multiple. The interface logic ensures  
that the NI 1405 can meet PCI loading, driving, and timing requirements.  
Start Conditions  
The NI 1405 can start acquisitions in a variety of conditions:  
Software control—The NI 1405 supports software control of  
acquisition start. You can configure the NI 1405 to capture a fixed  
number of fields or frames. Use this configuration for capturing a  
single frame or a sequence of frames.  
Trigger controlYou can start an acquisition by enabling the  
external trigger line. This input can start a video acquisition on a  
rising or falling edge.  
Frame/field selection—With an interlaced camera and the NI 1405 in  
frame mode, you can program the NI 1405 to start an acquisition on  
any odd or even field.

Hardware Overview  
Acquisition Window Control  
You can configure numerous parameters on the NI 1405 to control the  
video acquisition window. A brief description of each parameter follows:  
Acquisition window—The NI 1405 allows you to specify a particular  
region of active pixels and active lines within the incoming video data.  
The active pixel region selects the starting pixel and number of pixels  
to be acquired relative to the assertion edge of the horizontal (or line)  
enable signal from the camera. The active line region selects the  
starting line and number of lines to be acquired relative to the assertion  
edge of the vertical (or frame) enable signal.  
Region of interestThe NI 1405 uses a second level of active pixel  
and active line regions for selecting a region of interest. When you  
disable the region-of-interest circuitry, the device stores the entire  
acquisition window into onboard or system memory. However, when  
you enable the region-of-interest circuitry, the device acquires only a  
selected subset of the image frame.

Introduction to Color  
Color is the wavelength of the light we receive in our eye when we look at  
an object. In theory, the color spectrum is infinite. Humans, however, can  
see only a small portion of this spectrum—the portion that goes from the  
red edge of infrared light, which is the longest wavelength, to the blue edge  
of ultraviolet light, which is the shortest wavelength. This continuous  
spectrum is called the visible spectrum, as shown in Figure A-1.  
Figure A-1. White Light and the Visible Spectrum  
White light is a combination of all colors at once. The spectrum of white  
light is continuous and goes from ultraviolet to infrared in a smooth  
transition. You can represent a good approximation of white light by  
selecting a few reference colors and weighting them appropriately.  
The most common way to represent white light is to use three reference  
components, such as red, green, and blue (R, G, and B primaries). You  
can simulate most colors of the visible spectrum using these primaries.  
For example, video projectors use red, green, and blue light generators,  
and an RGB camera uses red, green, and blue sensors.

Appendix A  
Introduction to Color  
The perception of a color depends on many factors, such as the following:  
Hue, which is the perceived dominant color. Hue depends directly on  
the wavelength of a color.  
Saturation, which is dependent on the amount of white light present in  
a color. Pastels typically have a low saturation while very rich colors  
have a high saturation. For example, pink typically has a red hue but  
has a low saturation.  
Luminance, which is the brightness information in the video picture.  
The luminance signal amplitude varies in proportion to the brightness  
of the video signal and corresponds exactly to the monochrome  
picture.  
Intensity, which is the brightness of a color and is usually expressed as  
light or dark. For example, orange and brown may have the same hue  
and saturation; however, orange has a greater intensity than brown.  
Image Representations  
Color images can be represented in several different formats. These formats  
can contain all color information from the image or they can consist of only  
one aspect of the color information, such as hue or luminance. The  
following image representations can be produced using the NI 1405.  
RGB  
The most common image representation is 32-bit RGB format. In this  
representation, the three 8-bit color planes—red, green, and blue—are  
packed into an array of 32-bit integers. This representation is useful for  
displaying the image on a monitor. The 32-bit integer is organized as  
follows:  
0
RED  
GREEN  
BLUE  
where the high-order byte is not used and the low-order byte is blue.  
Color Planes  
The red, green, or blue planes can be returned individually. Each plane is  
extracted from the RGB image and represented as an array of 8-bit integers.

Appendix A  
Introduction to Color  
Hue, Saturation, Luminance, and Intensity Planes  
The NI 1405 can return an 8-bit Luminance (L) plane, but not Hue (H) or  
Saturation (S) planes. You can use the NI Vision Development Module or  
Vision Builder AI to convert the RGB data from the NI 1405 to HSL or  
Hue, Saturation, and Intensity (HSI) planes.  
Luminance, intensity, hue, and saturation are defined using the red, green,  
and blue values in the following formulas:  
Luminance = 0.299 × Red + 0.587 × Green + 0.114 × Blue  
Intensity = (Red + Green + Blue) / 3  
Hue = ATN2 (Y, X)  
where  
Y = (Green – Blue) / 2 and  
X = (2 × Red – Green – Blue) / 6  
3 × Min(R, G, B)  
Saturation = 255 × 1 -----------------------------------------  
R + G + B  
32-Bit HSL and HSI  
You can also pack the three 8-bit HSL planes or the three HSI planes  
in one array of 32-bit integers, which is equivalent to the 32-bit RGB  
representation.

Glossary  
F
field  
For an interlaced video signal, a field is half the number of horizontal  
lines needed to represent a frame of video. The first field of a frame  
contains all the odd-numbered lines, the second field contains all of  
the even-numbered lines.  
FIFO  
frame  
First-in first-out memory buffer. The first data stored is the first data sent  
to the acceptor; FIFOs are used on devices to temporarily store incoming  
data until that data can be retrieved.  
A complete image. In interlaced formats, a frame is composed of two fields.  
H
HSI  
Color encoding scheme using Hue, Saturation, and Intensity information,  
where each pixel in the image is encoded using 8 bits for hue, 8 bits for  
saturation, and 8 bits for intensity.  
HSL  
hue  
Color encoding scheme using Hue, Saturation, and Luma information  
where each pixel in the image is encoded using 32 bits: 8 bits for hue, 8 bits  
for saturation, 8 bits for luma, and 8 unused bits.  
Represents the dominant color of a pixel. The hue function is a continuous  
function that covers all the possible colors generated using the R, G, and  
B primaries. See also RGB.  
I
I/O  
Input/output. The transfer of data to/from a computer system involving  
communications channels, operator interface devices, and/or data  
acquisition and control interfaces.  
instrument driver  
intensity  
A set of high-level software functions, such as NI-IMAQ, that control  
specific plug-in computer boards. Instrument drivers are available in  
several forms, ranging from a function callable from a programming  
language to a virtual instrument (VI) in LabVIEW.  
The sum of the red, green, and blue primaries divided by three:  
(red + green + blue)/3.

a field are half the number of lines in an interlaced frame.  
A computer signal indicating that the CPU should suspend its current task  
to service a designated activity.  
L
luma  
The brightness information in the video picture. The luma signal amplitude  
varies in proportion to the brightness of the video signal and corresponds  
exactly to the monochrome picture.  
M

Mean time between failure.  
N
NI-IMAQ  
Driver software for National Instruments hardware.  
NTSC  
National Television Standards Committee. The committee that developed  
the color video standard used primarily in North America, which uses  
525 lines per frame. See also PAL.  
NVRAM  
Nonvolatile RAM. RAM that is not erased when a device loses power or is  
turned off.  
P

instead of being accumulated and processed at a later time.  
resolution  
The smallest signal increment that can be detected by a measurement  
system. Resolution can be expressed in bits, in proportions, or in percent of  
full scale. For example, a system has 12-bit resolution, one part in 4,096  
resolution, and 0.0244 percent of full scale.
