1. A method of capturing an image with an imager having image sensing pixels arranged in rows and columns, wherein each of the image sensing pixels comprises a storage device having a capacitance, the method comprising: isolating reset lines from a reset voltage so that the reset lines have floating voltages, wherein each of the reset lines has a capacitance and is associated with a respective one of the columns of image sensing pixels; and while the reset lines are isolated from the reset voltage, supplementing the capacitances of the storage devices in a given row of image sensing pixels with the capacitances of the reset lines by coupling each of the reset lines to a respective one of the storage devices in the image sensing pixels in the given row.
