1. An imaging device, comprising:

  • an array of pixels wherein each active pixel of said array of pixels is individually subjected to a series of tasks comprising;

    selection and initiation of an available integration period for a given pixel and recording of an indication of an integration period initiated for said given pixel; and

    taking a single digitized reading of an integrated charge on said given pixel using a selected integration period at a site which is at least partially outside of said array of pixels and output of a signal representing a light level reading for said given pixel based on said digitized reading and said selected integration period;

    wherein a reset task and said read task are interleaved to be performed without conflicting requirements for use of components included in said site which is at least partially outside of said array of pixels; and

    wherein at least one of said available integration periods is an integration period shorter than said row read task.
