Claim 11:
12. A method of resetting a voltage at a sense node of a pixel circuit, the method comprising:
coupling, using a first switch of the pixel circuit, an input node of a reset voltage correction circuit to a correction node, the input node being connected to the sense node or to the source of a first transistor, the correction node being coupled by a capacitance to the sense node, the sense node being coupled to a light-sensing element, wherein the first transistor has its control node coupled to a sense node and its source coupled to a readout path of the pixel circuit, and the capacitance coupling the correction node to the sense node is implemented at least partially by a capacitance present between the control node of the first transistor and a bulk of the first transistor; and
coupling, using a second switch, the correction node to a reset voltage.
