Abstract: A method of processing video information includes scaling the video information using a first number of fields if a field indicator indicates the first number of fields and scaling the video information using a second number of fields if the field indicator indicates the second number of fields. The video information is searched for motion. The field indicator is set to indicate the first number of fields if the video information includes a first amount of motion, and the field indicator is set to indicate the second number of fields if the video information includes a second amount of motion.

Abstract: An optical tracking system 10 is provided which comprises a beam source 12 which generates a light beam. The light beam travels through a splitter/filter 14 and proximate a DMD array 16. The DMD array 16 is controlled by a DMD array control system 18 which causes a single element within the DMD array to deflect the light beam towards a selected track on an optical storage medium 22. The optical storage medium 22 reflects the beam dependent upon the data stored on the selected track. The reflected beam is deflected by the DMD array 16 back to the splitter/filter 14 which separates the reflected beam from the impinging beam and directs the reflected beam to a detector 24 which discerns the information stored in the storage medium 22 responsive to the receipt of the reflected beam.

Abstract: An optical tracking and positioning system is provided which comprises a beam source 14 which generates a beam which is transmitted through a splitter/filter 16. The beam issues from splitter/filter 16 and is selectively deflected to areas of an optical storage medium 12 by a mirror 18 which is controlled by a mirror control system 20. The beam is transmitted from mirror 18 through correction optics 22 and reflects off the surface of the optical storage medium 12. The beam returns along a coincident path and is separated by splitter/filter 16 and directed to a detector 24 which reads the data stored in optical storage medium 12. According to a preferred embodiment of the present invention, the mirror 18 comprises a deformable mirror device 26.
