Claim 14:
15. A unit pixel comprising:
a first photoelectric converter configured to convert received light into charges;
a first transfer transistor electrically connected between the first photoelectric converter and a first node;
a first connection transistor electrically connected between a second node and the first node;
a dual conversion transistor electrically connected between a third node and the second node;
a second connection transistor electrically connected between a fourth node and the third node;
a second photoelectric converter electrically connected to the third node and configured to convert the received light into charges;
a second transfer transistor electrically connected to the second photoelectric converter and the third node;
a first capacitor configured to store charges that overflow from the second photoelectric converter;
a second capacitor physically separated from the first capacitor, wherein the second capacitor is configured to store charges that overflow from the second photoelectric converter;
a first switch configured to selectively electrically connect the first capacitor to the fourth node;
a second switch configured to selectively electrically connect the second capacitor to the fourth node;
a third switch configured to selectively electrically connect the first capacitor to the third node; and
a fourth switch configured to selectively electrically connect the second capacitor to the third node,
wherein a first voltage is configured to be applied to the first node, the second node, the third node, and the fourth node,
wherein a second voltage different from the first voltage is configured to be applied to the first capacitor and the second capacitor.
