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.

Claim (Index 1):
An A/D conversion circuit comprising:\n a plurality of capacitive elements that are capacitively coupled to a node to which a pixel signal is input through a vertical signal line of a solid-state image pickup apparatus; a pixel signal holding unit that is configured to hold in advance a plurality of pixel signals input through the vertical signal line, using some of the plurality of capacitive elements; a node potential generation unit that is configured to generate a potential of the node by synthesizing the pixel signals held in some of the capacitive elements; and a control unit that is configured to change the potential of the node by changing voltages of counter electrodes of the plurality of capacitive elements, and is configured to generate digital values of the pixel signals by comparing the potential of the node with a predetermined potential.
