Abstract:
1. An imaging apparatus including a plurality of pixels configured to output signals derived by photoelectric conversion, the imaging apparatus comprising a plurality of memory capacitors configured to hold the signals outputted from the plurality of pixels; a common signal line configured to transmit the signals held by the plurality of memory capacitors; a reference potential supplying unit configured to supply a reference potential; and a plurality of first switches configured to respectively connect each of the plurality of memory capacitors to the common signal line, wherein each of the plurality of memory capacitors has a first terminal connected to the first switch and supplied with a signal outputted from a pixel, and a second terminal to which the reference potential is applied, and the reference potential supplying unit supplies a first reference potential during a period of holding the signals by the plurality of memory capacitors, supplies a second reference potential during a part of a period of turning on a first switch, and supplies the first reference potential before the first switch is turned off, such that a potential difference between the second reference potential and a potential of the common signal line before turning on the first switch is greater than a potential difference between the first reference potential and the potential of the common signal line before turning on the first switch.
