Abstract
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.
Claims10
An image capturing apparatus that includes a first image sensor and a second image sensor each including a plurality of pixels arrayed in a matrix, a driving unit, and a signal readout unit,
- wherein each of the plurality of pixels includes a photoelectric conversion element, a first signal holding unit, a first transferring unit configured to transfer a signal according to an amount of charges generated in the photoelectric conversion element to the first signal holding unit, a second signal holding unit, and a second transferring unit configured to transfer a signal according to an amount of charges generated in the photoelectric conversion element to the second signal holding unit, and
- the driving units
- perform, on each of the first image sensor and the second image sensor, first driving of causing the first transferring unit to transfer, to the first signal holding unit, a signal according to an amount of charges generated in the photoelectric conversion element in a first period in accordance with an amount of light from an object which is not irradiated with light by a light irradiation unit, and causing the first signal holding unit to hold the signal as an image signal,
- perform, on the first image sensor, second driving of causing the second transferring unit to hold, in the second signal holding unit, a signal generated in the photoelectric conversion element in a second period based on reflected light from the object irradiated with the light by the light irradiation unit, and
- perform, on the second image sensor, third driving of causing the second transferring unit to hold, in the second signal holding unit, a signal generated in the photoelectric conversion element in a third period based on reflected light from the object irradiated with the light by the light irradiation unit, the third period including a period which does not overlap the second period.
