ON Semiconductor has launched the first devices in its new PYTHON CMOS image sensor family. With resolutions of 300 K, 500 K and 1.3 Mega pixels (MPix) respectively, the PYTHON 300, 500 and 1300 are designed to address the needs of general purpose industrial image sensing applications such as machine vision, inspection and motion monitoring, as well as security and surveillance applications including intelligent transportation systems (ITS).

The image sensors combine flexibility in configuration and resolution with high speed and high sensitivity for the industrial imaging market.

ON Semiconductor has an already extensive patent portfolio within the image sensing space, including new coverage for in-pixel CDS (ipCDS) technology enabling global shutter imaging with Correlated Double Sampling (CDS) in a compact pixel size, resulting in CCD-like optical performance with attractive combinations of optical format and resolution.

This new pixel allows the capture of fast moving scenes without distortion by combining a read noise of less than 9 e-, with 7.7 V/lux sensitivity and frame rates as high as 850 frames per second. A highly configurable sequencer also allows designers to tailor the sensor operation to the exact needs of the application, including support for fast on the fly updates to the sensor configuration. Operational support across the -40°C to +85°C industrial temperature range further underlines the sensor's versatility.

The new VGA, SVGA and SXGA are the first three sensors in the PYTHON family, with additional higher resolutions planned for release in the near future. All are pin-to-pin compatible with one-another and with the existing VITA1300 image sensor. The result is a hardware scalable product family where all sensors have the same data, control and optical interface, allowing camera vendors to rapidly roll-out multiple resolutions to the market with minimised development effort.
