The CCD image sensors used in video cameras are area sensors comprising a matrix of sensor elements or pixels. The image signal is acquired in the form of electrical charge by the sensor elements, read into a plurality of vertical transfer registers, then shifted into a horizontal transfer The personal computer market has grown rapidly in the past decade. Recent trends have focused on the configuration of the computer to perform a variety of user defined functions, including connecting to the internet and communicating with others also so connected.
