Abstract
An imaging system provides a serial video signal that is indicative of the intensity of the light. The imaging system has an array of pixel image sensors arranged in rows and columns. A control circuit is in communication with the rows of the array and the plurality of column switches. The control circuit generates reset control signals, transfer gating signals, pixel image sensor initiation signals for each selected row for controlling resetting, integration of photoelectrons generated from the light impinging upon the array of pixel image sensors, charge transfer of the photoelectrons from the photosensing devices to the charge storage device, and to activate the photoelectron sensing devices on each row to generate output signals from each of the pixel image sensors on a selected row. The control circuit generates the column selection signals for transfer of the output signals from selected rows to form a serial video output signal.
