Digital Cameras

Overview and Applications

Digital cameras have several advantages over analog cameras. During

transmission, analog video is more susceptible to noise than digital video.

Digitizing at the CCD camera, rather than at the image acquisition board,

increases the signal-to-noise ratio, resulting in better accuracy. In addition,

standard digital cameras now come with 10- to 12-bit gray levels of resolution.

The higher resolution is often necessary in medical, machine vision, astronomy,

and scientific imaging applications.

The NI PCI-1424 is a digital camera image acquisition board for acquiring color

and grayscale images and controlling digital cameras. Designed for high-speed,

large-image, high-resolution digital image capture, the board can capture into

onboard memory up to 32 bits of data at a clock speed of 50 MHz, for a total

acquisition rate of 200 MB/s. Onboard memory (16 to 80 MB) gives you the

flexibility to buffer images on the board for large-image capture and sustained

real-time throughput. You can choose from two versions of the board – one

compatible with digital cameras that use RS422 and another compatible with

digital cameras that use LVDS.

Easy Camera Conﬁguration

Configure digital image acquisition from your digital camera with

NI Measurement & Automation Explorer (MAX), which is delivered with

NI Vision Acquisition Software. This configuration utility is an interactive tool

for setting up region of interest and camera control. Plus, you can use MAX to

control the serial interface for communicating with the camera. Both the

PCI-1422 and PCI-1424 use a 100-pin SCSI-type connector that you can easily

cable to your specific camera. In addition, MAX includes specific camera setup

files, so you can quickly configure your camera for acquisition. For a list of

applicable cameras, visit ni.com/camera.

The NI PCI-1422 is designed to acquire images from a wide range of digital

cameras. These boards perform high-speed, large-image, high-resolution digital

image capture and can capture up to 16 bits of data at a clock speed of 40 MHz

for a total acquisition rate of 80 MB/s. Onboard memory (16 MB) gives you the

flexibility to buffer images on the board for large-image capture and sustained

real-time throughput. There are two versions of the board – one compatible

with digital cameras that use RS422 signals and another compatible with

digital cameras that use LVDS. The PCI-1422 is ideal for both industrial and

scientific applications.
