Abstract
Portable device, like a digital camera, is equipped with a GPS receiver, thereby detecting a current position. When a change does not occur in the detected current position for a given period of time or more, the position is considered to be a living sphere, like a user'"'"'s home. When the user is situated in the living sphere, a receive cycle of the GPS receiver is increased so as to become larger than a normal receive cycle, thereby reducing power consumption.
