ABSTRACT:
The effective light incident upon pixels of an X-Y addressable imager is controlled by electrically controlling the effective photonic charging time of each pixel in each frame time of operation. The horizontal signal lines of the imager are assigned to different groups, and each group is coupled through a different one of plural vertical signal lines to a common output circuit. A multiplexer couples one vertical signal line at a time to the common output circuit. Imager array scanning logic is provided for recurrently selecting pixels of two of the horizontal signal lines at a time, but connecting only one of them to its vertical signal line at that time, for effecting variable integration by array pixels.
