Provided are a reception apparatus and a reception method that are capable of acquiring altitude information by a method suitable for a wearable device and improving position calculation accuracy. The reception apparatus includes an altitude information acquisition unit and a positioning calculation unit. The altitude information acquisition unit acquires altitude information externally calculated via proximity wireless communication. The positioning calculation unit performs positioning computation on the basis of a received global navigation satellite system (GNSS) signal and the altitude information supplied from the altitude information acquisition unit.

Reception apparatus and reception method

In an imaging apparatus for driving a lens system mounted a housing by way of a linear motor, a detection is made of a component of force along an optical axis direction, among external force applied to the lens system based upon a drive current outputted from the lens driving means under control of the control means during the stationary servo mode. As a result, the component force given to the lens system along the optical axis direction can be detected. Thus, a so-called 'ground imaging operation' in which the camera is inadvertently left on and pointed at the ground can be prevented without providing any sensor of the optical axis.
