Abstract

A position information recorder incorporated in a camera comprises a position measurement unit that receives position information via a GPS which is a position measurement system using satellites and that performs position measurement to calculate a position, a receiving state determination unit that determines the state of receiving the position information, a memory that stores position measurement data, and a magnetic recording unit that records data in the magnetic recording area of film. When position measurement data cannot be fetched, position measurement information stored in the memory immediately before is read out and recorded.
