An image sensor having a plurality of pixels; each pixel includes one or more photosensitive elements that collect charge in response to incident light; one or more transfer mechanisms that respectively transfer the charge from the one or more photosensitive elements; a charge-to-voltage conversion region having a capacitance, and the charge-to-voltage region receives the charge from the one or more photosensitive elements; a first reset transistor connected to the charge-to-voltage conversion region; a second reset transistor connected to the first reset transistor, which in combination with the first reset transistor, selectively sets the capacitance of the charge-to-voltage conversion regions from a plurality of capacitances.
