Image capturing apparatus and control method thereof, and storage medium

摘要

An image capturing apparatus comprises a solid-state image sensor including a pixel area where a plurality of unit pixels are arranged, each of the unit pixels including a photoelectric conversion portion, a first charge holding portion, a first charge transfer portion, a second charge holding portion, and a second charge transfer portion, a light projection unit, and a control unit configured to control to set the second charge transfer portion in an OFF state synchronized with a light projection operation by the light projection unit while keeping the first charge transfer portion in an ON state after controlling the photoelectric conversion portion to perform photoelectric conversion, and setting the first charge transfer portion and the second charge transfer portion in the ON states.

主权项

1. An image capturing apparatus comprising:
an image sensor including a pixel area where a plurality of unit pixels are arranged, each of the unit pixels including a photoelectric conversion portion configured to convert incident light into charges, a first charge holding portion, a second charge holding portion, a third charge holding portion, a first charge transfer portion provided between the photoelectric conversion portion and the first charge holding portion and configured to transfer charges accumulated in the photoelectric conversion portion to the first charge holding portion, a second charge transfer portion provided between the first charge holding portion and the second charge holding portion and configured to transfer charges held in the first charge holding portion to the second charge holding portion, and a third charge transfer portion provided between the second charge holding portion and the third charge holding portion and configured to transfer charges held in the second charge holding portion to the third charge holding portion; a light projector which projects light to an object; and a controller which controls said image sensor and said projector to set the second charge transfer portion in an OFF state synchronized with a light projection operation by said light projector while keeping the first charge transfer portion in an ON state after controlling the photoelectric conversion portion to perform photoelectric conversion, and setting the first charge transfer portion and the second charge transfer portion in the ON states.
