Claim 6:
7. The image sensor of claim 1, each pixel circuit comprises an output (vlg_out) connected between the bias transistor (MVB) and the source follower transistor (MSF), and
wherein at least one of the plurality of pixels circuits is configured such that:
the second additional transistor (MS2) connects the drain of the bias transistor (MVB) to the drain of the reset transistor (MRST),
the third additional transistor (MS3) is open,
the fourth additional transistor (MS4) connects the drain of the reset transistor (MRST) and the gate of the reset transistor (MRST), and
the row select transistor (MSEL) is closed and the common column output is connected to ground,
whereby the at least one pixel circuit generates a logarithmic output signal.
