Enhancing the charge-coupled device (CCD) image sensor portfolio recently acquired from Truesense Imaging, ON Semiconductor has announced the KAI-08051. This image sensor provides improved light sensitivity, reduced read noise, and improved colour accuracy for 8MP image capture in demanding intelligent traffic, surveillance, medical imaging and industrial inspection applications.

Compared to the previous generation device, the KAI-08050, this image sensor shares the same advanced 5.5 micron pixel architecture, 8MP resolution, 15fps readout rate and 4/3 optical format. However, the latest image sensor improves key performance parameters through the use of an improved amplifier design, newly optimised microlens structure, and new colour filter pigments in both Bayer and Sparse colour configurations.

Backward compatible with the KAI-08050, the KAI-08051 requires just minor modifications to the firmware used in existing camera designs. This enables it to retain 'Plug-and-Play' interoperability with the full family of 5.5-micron Interline Transfer CCD devices. Therefore, a single camera design can support image sensors of 1-29MP resolution.

Chris McNiffe, Vice President, Image Sensor Business, ON Semiconductor, comments: “CCD image sensors continue to provide the critical image quality required in many key applications. The enhanced performance available from the KAI-08051 Image Sensor reflects our on-going commitment to improve the capability of our existing products and to deliver the industry’s most advanced image sensors using both CCD and CMOS technology."

The KAI-08051 image sensor is now in production and is available in Monochrome, Bayer Colour, and Sparse Colour configurations. ON Semiconductor also provides an evaluation kit that allows the imaging performance of this device to be quickly and easily examined in detail without the need to develop a full camera design.
