8 megapixel CCD image sensor boosts sensitivity, cuts noise

Offering uprated performance for intelligent traffic, surveillance, medical imaging and industrial inspection, ON Semiconductor’s KAI-08051 image sensor includes technology acquired with Truesense Imaging

Using the charge-coupled device (CCD) image sensor portfolio recently acquired from Truesense Imaging, with new technology that improves imaging performance for industrial applications, the KAI-08051 Image Sensor provides improved light sensitivity, reduced read noise, and improved colour accuracy compared to the previous generation device, expanding opportunities for 8 megapixel image capture in intelligent traffic, surveillance, medical imaging, and industrial inspection.

The KAI-08051 Image Sensor shares the same 5.5 micron pixel architecture, 8 megapixel resolution, 15 frame per second readout rate, and 4/3 optical format as the existing KAI-08050 Image Sensor, but 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. The KAI-08051 is backward compatible with the KAI-08050, requiring, at most, minor modifications to the firmware used in existing camera designs. This allows the new image sensor to retain “Plug-and-Play” interoperability with the full family of 5.5-micron Interline Transfer CCD devices, enabling a single camera design to support image sensors ranging in resolution from 1 to 29 megapixels.

The sensor is available in Monochrome, Bayer Colour, and Sparse Colour configurations. An evaluation kit is available that allows the imaging performance of this new device to be quickly and easily examined in detail without the need to develop a full camera design.
