Camera is PC-controllable
The CV-A11 compact progressive-scan 1/3-in. monochrome CCD camera comes in a 29 x 44 x 66-mm housing and eliminates operator setup errors by means of an RS-232C command protocol that allows camera setup from a PC. A partial scanning capability is software configurable for 1/2, 1/3, or 1/6 of the vertical resolution imaging area. By eliminating unnecessary pixels from the image area, scan rates from 56 to 124 frames/s can be achieved. JAI America Inc., Laguna Hills, CA 92653; (949) 472-5900.
Camera uses remote head
Aimed at online-inspection, barcode-reading, gauging, and character-recognition applications, the IK-7XD remote-head video camera captures objects at 60 frames/s using a progressive-scan, 1/2-in. CCD sensor with square pixels. Other features include an effective resolution of 659 x 494 pixels, a variable shutter rate from 1/60 to 1/100,000 s, and a signal-to-noise ratio of 56 dB.

Software runs on laptops The NI-IMAQ software for IEEE 1394 cameras can analyze and process images from an IEEE 1394-compatible camera on a laptop computer. It contains a set of virtual instruments (VIs) and C functions for creation of LabVIEW and Measurement Studio programs. The driver VIs and C functions contained in the software are seamlessly integrated with IMAQ Vision so that an IEEE 1394 camera can be connected to a laptop computer and begin acquiring images. Using IMAQ Vision, images can be analyzed and processed as they are acquired. NI-IMAQ can be used for color-image acquisition at 30 frames/s at up to 640 x 480-pixel resolution.
