Original Abstract Submitted
A pixel layout is optimized. An amplification unit generates a signal corresponding to a charge held in a charge holding unit and outputs the signal to a predetermined first output node. A first capacitive element has one end connected to the first output node and holds a reset level that is a level of the signal at the time of resetting. A second capacitive element has one end connected to the first output node and holds an image signal level that is a level of the signal when the charge is transferred to the charge holding unit. A readout circuit is connected to a second output node, reads each of the reset level held in the first capacitive element and the image signal level held in the second capacitive element, and outputs the reset level and the image signal level as a reset signal and an image signal, respectively.
