Abstract: Provided is a pixel including a first photodiode, a second photodiode having a smaller light receiving area than the first photodiode, a storage capacitor configured to store charges generated by the second photodiode, and a plurality of floating nodes. The pixel according to the present disclosure includes first and second control transistors for transmitting a first voltage or a second voltage to a first node of the storage capacitor in a reset period and an exposure period, and for floating the first node by controlling the first and second control transistors in a readout period.
