IMAGE SENSORS: Overview
An image sensor is a device that converts an optical image to an electric signal, and is used in digital cameras and other imaging devices. Most digital still cameras use either a CCD images sensor or a CMOS sensor. A CCD is an analog device. When light strikes the chip it is held as a small electrical charge in each photo sensor. The charges are converted to voltage one pixel at a time as they are read from the chip. Additional circuitry in the camera converts the voltage into digital information. A CMOS chip is a type of active pixel sensor made using the CMOS semiconductor process. Extra circuitry next to each photo sensor converts the light energy to a voltage. Additional circuitry on the chip converts the voltage to digital data.

IMAGE SENSORS: Blogs
By Grant Martin, Tensilica, Inc. The concept of using multiple processors or processor cores to build systems has really taken on a life of its own lately. The au courant term is “multicore” although that term means different things to different people, much like the ancient story of the blind men and the elephant.
