1. A method for operating a stacked-chip image sensor, wherein the stacked-chip image sensor comprises a planar array of image sensor pixels, an array of vertical conductive vias, and processing circuitry coupled to the planar array of image sensor pixels through the array of vertical conductive vias, the method comprising: with the image sensor pixels, capturing a first set of image data; providing the captured first set of image data to the processing circuitry using the array of vertical conductive vias; with the processing circuitry, storing the first set of image data; with the image sensor pixels, capturing a second set of image data; with the processing circuitry, determining a motion score for the second set of image data by comparing the second set of image data to the stored first set of image data; and with the processing circuitry, generating an output image using the determined motion score, wherein the output image has a first region with a first effective integration time and a second region with a second effective integration time.
