1.3-Mpixel CMOS image sensor improves on sensitivity, performance

Eastman Kodak Company has expanded its portfolio of CMOS image sensors for mass-market consumer applications with a 1.3-Mpixel model targeted at camera phones. According to the company, the KAC-01301 cost effective sensor provides a level of image quality currently available from CCD image sensors, while taking advantage of the power, integration, and cost benefits traditionally associated with CMOS technology.

The KAC-01301 outputs raw, unprocessed data, thereby reducing the sensor's overall size and cost. In addition, the wide optical chief ray acceptance angle enables construction of low-profile imaging modules.

The sensor employs the company's Pixelux technology, an architecture that uses low dark current pinned photodiodes and a four-transistor shared pixel structure to enable the manufacture of a sensor that approaches the size of the smallest CCD devices offered today, while providing improved photosensitivity and lower noise. The shared pixel architecture allows for charge-domain binning of multiple pixels on the imaging array, enabling operating modes with increased sensitivity for low light image and video capture.

The KAC-01301 image sensor is expected to sample in the second quarter. For more information, visit www.kodak.com/go/imagers.
