An image capturing apparatus that includes a first and second image sensors each including pixel array and a driving unit, the driving units perform first driving, in a first period, such that a signal based on a light from non-irradiated object is held in a first signal holding unit of each of the first and second image sensors, second driving, in a second period, such that a signal based on a light from irradiated object is held in a second signal holding unit of the first image sensor, and third driving, in a third period, such that a signal based on a light from irradiated object is held in a second signal holding unit of the second image sensor, the third period including a period which does not overlap the second period.
