Claim 2:
3. The read circuit for the image sensor according to claim 2, wherein the switched capacitor array comprises a first capacitor, K number of second capacitors, and the K number of changeover switches, wherein
a first end of the first capacitor and a first end of each of the second capacitors are connected to the first input end;
a second end of the first capacitor is used for the input of a ramp signal;
a second end of each of the second capacitors is electrically connected to a fixed end of one of the changeover switches,
each of the changeover switches has at least two switching ends, wherein a first reference voltage and a second reference voltage are respectively input at the at least two switching ends; and
the control logic module is electrically connected to the each changeover switch to switch voltage signals input by the each changeover switch.
