Classification: CPC H | IPC H

Claim 8:
9. 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 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 transfer transistor electrically connected between a fourth node and the third node;
a second photoelectric converter that is electrically connected to the fourth node and configured to convert the received light into charges;
a first switch electrically connected between the second photoelectric converter and the fourth node;
a first capacitor that is electrically connected to the fourth node, wherein the first capacitor is configured to store charges that overflow from the second photoelectric converter; and
a second capacitor that is electrically connected to the third node, wherein the second capacitor is configured to store charges that overflow from the second photoelectric converter,
wherein the unit pixel is configured to perform operations comprising:
converting the charges accumulated in the first photoelectric converter into a first signal voltage, and outputting the first signal voltage for a first time period;
converting the charges accumulated in the first photoelectric converter into a second signal voltage, and outputting the second signal voltage for a second time period subsequent to the first time period; and
converting the charges accumulated in the first photoelectric converter, the first capacitor, and the second capacitor into a third signal voltage, and outputting the third signal voltage for a third time period subsequent to the second time period.
