METHODS AND APPARATUS FOR IMPROVING RESOLUTION AND REDUCING THE EFFECTS OF SIGNAL COUPLING IN AN ELECTRONIC IMAGER

摘要

An electronic imager includes a detector array, a plurality of processing circuits, each responsive to an output signal from a respective detector element of the array and to a determination that signal coupling in general or charge sharing in particular occurred. The imager further includes a shared channel circuit coupled to at least two processing circuits for receiving an output signal from the processing circuits in response to a determination that signal coupling has occurred and for generating an output signal in response to the received signals. The shared channel circuit further directs the output signal to an image sub-pixel, wherein a plurality of sub-pixels are associated with each radiation sensitive element.
