Video controlled servo tracking.

This was a TI demo at the Embedded systems conference.

Critical Link, Mity DSP

They support some really high end scientific cameras and regular Machine Vision CCD's.

MityCCD is a family of high-performance scientific cameras meant for OEM applications.  The MityCCD imaging platform utilizes a number of key technologies.  Low noise analog front-end electronics are well matched to the target sensors and deliver a very low noise signal.  A digital subsystem consists of a 16 bit ADC, USB and Ethernet communication interfaces, and high-performance CPU engine.  The CPU (MityDSP TM) provides the capability of running complex and sophisticated applications directly on the camera.  Other key technologies are a vacuum chamber and TE cooling for low dark current, and a line up of mechanical enclosures that fit many environments.
