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.

Chapter 2
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 control—You 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.

Chapter 2
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 interest—The 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.

chroma information are transmitted on one analog signal.
A constant multiplication factor applied to the luma and chroma
components of a color pixel in the color decoding process.
D
DAQ
Data acquisition. (1) Collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and inputting them to a
computer for processing. (2) Collecting and measuring the same kinds of
electrical signals with A/D or DIO boards plugged into a computer and
possibly generating control signals with D/A and/or DIO boards in the
same computer.
DMA
Direct memory access. A method by which data can be transferred to
and from computer memory from and to a device or memory on the bus
while the processor does something else; DMA is the fastest method of
transferring data to/from computer memory.
driver
Software that controls a specific hardware device, such as an image
acquisition device.
dynamic range
The ratio of the largest signal level a circuit can handle to the smallest
signal level it can handle (usually taken to be the noise level), normally
expressed in decibels.
E
external trigger
A voltage pulse from an external source that triggers an event, such as
A/D conversion.

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
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.

Glossary
interlaced
interrupt
A video frame composed of two interleaved fields. The number of lines in
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
MTBF
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
PAL
Phase Alternation Line. One of the European video color standards; uses
625 lines per frame. See also NTSC.
PCI
Peripheral Component Interconnect. A high-performance expansion bus
architecture originally developed by Intel to replace ISA and EISA. PCI
offers a theoretical maximum transfer rate of 132 Mbytes/s.
pixel
Picture element. The smallest division that makes up the video scan line;
for display on a computer monitor, a pixel’s optimum dimension is square
(aspect ratio of 1:1, or the width equal to the height).

Glossary
pixel count
The total number of pixels between two horizontal synchronization signals.
The pixel count determines the frequency of the pixel clock.
R
real time
A property of an event or system in which data is processed as it is acquired
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.
RGB
ROI
Color encoding scheme using red, green, and blue (RGB) color information
where each pixel in the color image is encoded using 32 bits: 8 bits for red,
8 bits for green, 8 bits for blue, and 8 bits for the alpha value (unused).
Region of interest. A hardware-programmable rectangular portion of the
acquisition window.
RS-170
RSE
The U.S. standard used for black-and-white television.
Referenced single-ended. All measurements are made with respect to
a common reference measurement system or a ground. Also called a
grounded measurement system.
S
saturation
The amount of color pigment present. The lower the saturation, the more
white is present in the color. Pink is a red with low saturation.
