Autofocus, image stabalization, etc. Seems perfect for UAV use. From robots.net
"Advasense has announced what they claim is the world's smallest 5MP autofocus camera module. The module, which was developed with the help of Creative Sensor Inc., uses a technology called Feedback Controlled Pixels (FCP) to reduce image lag and noise within the tiny sensor. The new moduled, the ASIO 5, is designed for mobile phones but looks ideal for robotics use."
