Dr. Fossum will discuss the technology story behind CMOS image sensors, from the invention to state of the art ubiquitous imaging.  He will also discuss some of the fundamental scientific principles behind image sensor operation and limits.  The Quanta Image Sensor, a new paradigm in image acquisition, will also be introduced.  The QIS moves the process of image formation from the physical pixel to a computational environment through the use of spatial and temporal oversampling and the elimination of read noise.
