Dr. MacEachern's project for 2008-2009 will be the development of a CMOS Active Pixel image sensor. This is the type of image sensor commonly used in cameraphones and most consumer-grade digital cameras. Students will be designing the following components: (1) the active pixel sensor itself; (2) read-out and addressing circuits; (3) low power and high speed amplifiers; (4) low power and high bandwidth analog to digital converters; (5) mixed-signal building blocks, such as comparators, amplifiers, and filters; (6) FPGA-based interface and test systems; (7) image processing algorithms in hardware; (8) auxiliary support circuits.
Industry is currently facing problems developing imagers that have high dynamic range (can be used in both low light and high light conditions), that perform well in low light conditions without showing excessive image noise, and that enable rapid image stabilization. If you've ever been frustrated by blurry, noisy pictures taken using your expensive cameraphone, this is your chance to fix things for the better.
