Abstract
Methods, apparatus and systems may operate to copy pixel charge, compensating for image subject shift within in an imaging array during exposure time of an imaging device. Activities may include transferring charge from one or more source pixels to one or more buffer pixels within the same pixel array, and copying the charge to destination pixels within the same pixel array prior to an end of the image integration time. Charge transfer may include transfer of charge from more than one array on a single die. Additional activities may include transferring charge from one or more source pixels to one or more destination pixels multiple times prior to the end of the image integration time.
