Claim 0:
1. An image sensor comprising:
an image sensor pixel array having active pixels and dark pixels; and
row control circuitry coupled to the active pixels and the dark pixels and configured to:
control a first set of the active pixels in a first operating condition to generate a first set of image signals,
control a first set of the dark pixels in the first operating condition to generate a first set of black level signals for the first set of image signals,
control a second set of the active pixels in a second operating condition to generate a second set of image signals, and
control a second set of the dark pixels in the second operating condition to generate a second set of black level signals for the second set of image signals, wherein the first and second sets of active pixels and the first and second sets of dark pixels each comprise a transistor and wherein the transistor is in a first state in the first operating condition and is in a second state in the second operating condition.
