20 megapixel Spark CMOS cameras

08 October 2013

Stemmer Imaging recently introduced the Spark SP-20000M-PMCL and Spark SP-20000C-PMCL industrial cameras. These high performance monochrome and colour 20 megapixel cameras, from JAI, operate at 30 frames per second, and their combination of speed and resolution makes them suitable for use in persistent surveillance, border security, aerial mapping, and other outdoor applications.

Incorporating the CMOSIS CMV20000 imager, the Spark series offers full frame resolution of 5120 x 3840 pixels with a dual CameraLink interface capable of supporting multiple data rates in either Medium or Full configurations. Power can be supplied through the CameraLink connectors using a dual-channel-powered frame grabber, or via a separate 12-pin connector.

Outdoor applications in particular are said to benefit from the cameras features such as automatic level control (ALC) linking shutter and gain for best exposures under changing light conditions and a built-in dual-slope high dynamic range mode for high contrast imaging situations. An extended operating range of -45°C to +70°C enables the camera to handle a variety of harsh temperature environments.

The SP-20000 has user-defined single and multiple region-of-interest (ROI) capabilities providing image capture flexibility with higher frame rates. Monochrome models include horizontal and vertical binning for increased sensitivity.
