It is desired to obtain a more valuable picture from the viewpoint of a person seeing the picture. An imaging device (100) includes an imaging unit (40), a position/posture detection unit (60) that detects a spatial displacement, and a data processing unit (50) that processes image data supplied from the imaging unit (40) in a format in accordance with the displacement detected by the position/posture detection unit (60). The imaging device (100) is built in a mobile phone or the like, for example. A lens unit (30) is often disposed on an imager included in the imaging unit (40).
