Abstract
An imaging apparatus comprises: a plurality of memory capacitors for holding signals output from pixels; and a plurality of first switches for respectively connecting the memory capacitors to a common signal line, wherein each of the plurality of memory capacitors includes a terminal connected to the corresponding first switch and supplied with the corresponding signal output from the corresponding pixel, and another terminal supplied with a reference potential, a reference potential supplying unit supplies a first reference potential during a period in which the plurality of memory capacitors hold the signals, and supplies a second reference potential having a potential difference from a potential of the common signal line before turning-on of the first switch, the potential difference being larger than that of the first reference potential, during a period in which the first switches are turned on.
