Claim One:
1. A method for operating a stacked-chip image sensor having a planar array of image pixels, control circuitry, storage and processing circuitry, a first two-dimensional array of conductive vias coupled between the planar image pixel array and the control circuitry and a second two-dimensional array of conductive vias coupled between the control circuitry and the storage and processing circuitry, the method comprising: with the image pixels, capturing an image frame; with the control circuitry, reading out the image frame over a portion of the first two-dimensional array of conductive vias; with the control circuitry, providing the image frame to the storage and processing circuitry over a portion of the second two-dimensional array of conductive vias; with the storage and processing circuitry, detecting a region of changing brightness in the image frame; and with the storage and processing circuitry, adjusting the region of changing brightness in the image frame.
