CMOS sensor in color
Using an IEEE-1394 FireWire interface, the PL-A642 2/3-in., progressive-scan color CMOS sensor provides 1280 x 1024-pixel resolution with addressable pixels that can adjust image resolution and position to suit the application. Operating at reduced resolutions enables the image to be panned or tilted. Images can also be flipped or viewed as a mirror image. Frame rate can range in excess of 100 frames/s. A user interface allows adjustment of all camera parameters. Auto white balance compensates for color temperature changes. Three scene files can store and recall user parameters. Other features include a Twain driver, developer's software kit, FireWire card and cable, sample programs, and application-specific software code.
