Kodak brings functionality such as image stabilization, red-eye reduction and face recognition to camera handsets.
Kodak's new KAC-05020 image sensor is the world's first 1.4 micron CMOS pixel device, offering up to a 5-megapixel image resolution. After rethinking the design of the CMOS pixel and leveraging the work with high sensitivity color filter patterns and algorithms, Kodak will be ready to deliver the new sensor in large scale to cell phone manufacturers such as Motorola by the end of 2008.
At 5-megapixels, the KAC-05020 enables imagery up to ISO 3200 and support for full 720p video at 30 fps. The sensor is also supported by the TI OMAP and OMAP-DM solutions, enabling a host of Kodak's image processing and enhancement features, including digital image stabilization, rapid auto-focus, red-eye reduction, and face recognition.
Smaller and thinner camera phones, high performance under low light, and superior video performance are the types of features that will enable the next generation of consumer imaging devices, according to Fas Mosleh at Kodak's Image Sensor Solutions.
In a standard 1.75 micron CMOS pixel, signal is measured by detecting electrons, while Kodak's new image sensor detects the absence of electrons. This change has enabled a series of improvements to the design and structure of the pixel that ultimately results in CMOS imaging performance that rivals standard compact cameras using CCD image sensors.
Although 5-megapixel cameras are already available in handsets such as the Nokia N95, improved sensors will be crucial if camera phones should ever replace mainstream usage of standard compact cameras. Kodak's KAC-05020 image is the first true step towards this, and we wouldn't be surprised if Sony is the next sensor maker to announce improvements - perhaps already at next week's Mobile World Congress in Barcelona.
