Claim Text:
1. A pixel comprising: a plurality of photoelectric converters disposed on a substrate; a capacitor connected to the photoelectric converters, and accumulating electric charges converted by the photoelectric converters; a variable capacitor connected to the capacitor and connected directly to the substrate, and having capacitance varied according to a potential of the capacitor; and a switching element outputting the potential of the capacitor, wherein the switching element comprises: a transfer switching element provided between the photoelectric converters and the capacitor and between the photoelectric converters and the variable capacitor to transfer the electric charges converted by the photoelectric converters to the capacitor; a reset switching element provided between a power voltage line and the capacitor to reset the potential of the capacitor; and an output switching element connected to the power voltage line to output the potential of the capacitor, and wherein the capacitor and the variable capacitor are connected to the output switching element.
