Stemmer Imaging recently hosted the first showing of the Spark SP-20000M-PMCL and Spark SP-20000C-PMCL industrial cameras anywhere in the world. These two new, 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 ideal for persistent surveillance, border security, aerial mapping, and other outdoor applications.
Incorporating the CMOSIS CMV20000 imager, the Spark series of cameras offer 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 can be provided via the separate 12-pin connector.
Outstanding image quality with the highest degree of pixel uniformity results from the CMOSIS 8-transistor (8T) pixel architecture, while an industry-leading 1:50000 light rejection ratio gives clean images with sharp contrast. Additional in-camera correction routines have been included to provide significant reductions in pattern noise over previous generations of CMOS cameras.
Outdoor applications particularly benefit from 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. All models support horizontal and vertical mirroring.
