CCD image sensor boasts improved light sensitivity

ON Semiconductor has expanded the charge-coupled device (CCD) image sensor portfolio recently acquired from Truesense Imaging with its latest device that promises to improve 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 8MP image capture in demanding imaging applications such as intelligent traffic, surveillance, medical imaging and industrial inspection.

The KAI-08051 shares the same advanced 5.5um pixel architecture, 8MP resolution, 15fps readout rate, and 4/3 optical format as the existing KAI-08050, but improves key performance parameters through the use of an improved amplifier design, newly optimised microlens structure, and 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 image sensor to retain Plug-and-Play interoperability with the full family of 5.5um Interline Transfer CCD devices, enabling a single camera design to support image sensors ranging in resolution from 1-29MP.

The KAI-08051 image sensor is now in production and is available in Monochrome, Bayer Colour and Sparse Colour configurations. An evaluation kit is available 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.
