  • Patent number: 10805564
    Abstract: Provided is an ADC in which a plurality of pixel signals input through a vertical signal line of a solid-state image pickup apparatus are held in advance using some capacitors among a plurality of capacitors within the ADC. A potential of a node is generated by the respective pixel signals held in the capacitors. Thereafter, the potential of the node is changed by changing the voltages of counter electrodes of the capacitors, and the digital values of the pixel signals are generated by comparing the potential of the node with a predetermined potential.
