CMOS image sensor

ON Semiconductor has introduced two higher resolutions CMOS image sensors to its PYTHON product family. The new PYTHON 2000 and PYTHON 5000, with resolutions of 2.3MP and 5.3MP, respectively, address the needs of general purpose industrial image sensing applications such as machine vision, inspection and motion monitoring, as well as security, surveillance and intelligent transportation systems (ITS).

The PYTHON 2000 and PYTHON 5000 have been designed with a focus on performance, versatility and ease of use. Together with the previously released PYTHON 300, 500 and 1300, this entire family of sensors can be supported from a single PCB, greatly simplifying the design of a broad range of cameras offerings. The result is a hardware scalable product family where all sensors have the same data, control and optical interface, thus allowing camera manufacturers to rapidly roll out products with multiple resolutions, from VGA to 5MP, with greatly minimised development effort.

"The PYTHON family delivers a high-speed imaging solution without compromising image quality," said Chris McNiffe, VP of image sensor products at ON Semiconductor. "A choice of resolutions all supported by a single PCB—plus programmability and numerous features that enhance performance—combine to make the PYTHON family an important addition to the market that will allow designers of industrial image systems to meet the most stringent demands from their customers."

ON Semiconductor's patented in-pixel CDS (ipCDS) technology enables global shutter imaging with Correlated Double Sampling (CDS) in a compact pixel size, resulting in CCD-like optical performance in an attractive combination of optical formats and resolutions. The resulting PYTHON pixel allows the capture of fast moving scenes without distortion by combining a read noise of 9 e- with 7.7V/lux sensitivity and frame rates as high as 850fps (VGA).

The devices boast highly attractive speed and optical performance, high configuration flexibility including fast on the fly updates to sensor settings, various trigger and control options, and operational support across the -40°C to 85°C industrial temperature range. Both new sensors are available in mono, colour and extended Near-Infrared variants, further expanding PYTHON's capabilities.

PYTHON 2000 and PYTHON 5000 are sampling today, with full production expected in the first quarter of 2015.
