An image capturing apparatus comprises an image sensor in which a plurality of pixels are arranged two-dimensionally, wherein each of the pixels have a photoelectric conversion portion, a holding portion that holds a charge obtained by the photoelectric conversion portion, an amplification portion that outputs a signal based on a charge outputted from the holding portion, a first transfer switch that transfers the charge from the photoelectric conversion portion to the holding portion, and a second transfer switch that transfers the charge from the holding portion to the amplification portion; and a controller that controls a number of times that the first transfer switch is turned on in relation to the second transfer switch being turned on one time.
