PIXEL TO PIXEL CHARGE COPIER CIRCUIT APPARATUS, SYSTEMS, AND METHODS

摘要

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.

1. An imaging device comprising:
an array of pixels, wherein some of the pixels comprise:
a photosensor;an injection gate to inject a reference voltage into the photosensor during an integration time associated with acquiring an image;a bias gate coupled to the injection gate to supply the reference voltage to the injection gate;a transfer gate coupled to the photosensor to transfer a charge between pixels in the array; and a controller coupled to the array of pixels, wherein the controller is configured to transfer the reference voltage, and the charge from a first set of pixels in the plurality of pixels to a second set of pixels in the plurality of pixels, and from the second set of pixels in the plurality of pixels to a third set of pixels in the plurality of pixels by copying the charge.
