Abstract
A device of acquisition of a depth image of a scene by detection of a reflected light signal. The device includes a stack of a first sensor and of a second sensor. The first sensor includes first depth photosites configured to acquire at least one first sample of charges photogenerated during first time periods. The second sensor includes second depth photosites arranged opposite the first photosites, the second photosites being configured to acquire at least one second sample of charges photogenerated during second time periods offset with respect to the first time periods by a first constant phase shift. The first sensor or the second sensor further includes third photosites configured to acquire at least one third sample during third time periods offset with respect to the first time periods by a second constant phase shift.
