Solar cell technology cameras

A new camera range from Stemmer Imaging uses a sensor, based on solar cell technology, to allow imaging from scenes which simultaneously contain both very light and very dark areas. The company says this makes them ideally suited to use in environments with a very high dynamic range, or where there are strong and unpredictable brightness fluctuations. The new FX4 HDR (High Dynamic Range) sensor produces a logarithmic signal output. This enables fine differences in brightness to be imaged even in very bright

A new camera range from 822 Stemmer Imaging uses a sensor, based on solar cell technology, to allow imaging from scenes which simultaneously contain both very light and very dark areas. The company says this makes them ideally suited to use in environments with a very high dynamic range, or where there are strong and unpredictable brightness fluctuations. The new FX4 HDR (High Dynamic Range) sensor produces a logarithmic signal output. This enables fine differences in brightness to be imaged even in very bright scenes, without saturation.

 The FX4 HDR sensor features a patented pixel structure that provides a truly logarithmic output with effective suppression of fixed noise and gives a dynamic range of 120 db. According to Stemmer, this equates to a 1,000 times greater brightness ratio (ratio of the highest brightness value to the lowest brightness value that can be imaged in a scene) compared to conventional linear CCD sensors, which typically have a dynamic range of 60 db.

    Weather-related problems can render cost-cutting counter productive, according to CommScope’s Philip Sorrells. When severe weather conditions make headlines every winter, motorists and travellers seem willing to accept the impact on the trains and roads and yet take for granted that the communications networks will continue uninterrupted. They often appear far more upset that the information system does not give them an update on road conditions, train services or bus arrival times than they are about the a

    Lumenera claims its LtX45R cameras, based on Sony’s Pregius GS CMOS technology, provide CCD-like performance with increased frame rates and crisp, clear distortion-free images. The USB 3.1 Gen camera provides smear-free still images even when strong light sources are present in the frame, the company adds. Other features include a P-Iris connect for support of precise iris lens control, low read noise, USB3 Vision and Windows and Linux software development kits. Lumenera offers several GS CMOS camera model
