ABSTRACT:
A solid state image sensor architecture that utilizes drain structures at one or more locations on a shift register, as set by the design, allowing the user to select which charge packets are needed to represent the image and draining the remaining packets. Since the used packets are drained, there is no need to provide clock cycles to output charge packets that are not used while in the low resolution mode. Clocking can be stopped after the needed number of cycles without leaving charge packets in the shift register without the possibility of corrupting subsequent image information by charge packets that have not been removed. Additionally, the reduction in clock cycles decreases the time required to process the current information, and allows the system to operate at higher speeds.
