For example, a map database 16 including an IC card, a CD, or the like as an information recording medium and a character generator storing characters of position information such as a country name and a city name is provided. In addition, together with the place name stored in the map database 16, G
It is also possible to store a measurement error on a map based on the position information measured by the PS receiver 12, for example, place information subdivided into building names, park names, and the like divided in units of 10 m. In this case, the rough city name and the building corresponding to this city name,
A plurality of information recording media storing information such as park names may be prepared in advance.

The MPU 14 is connected to an operation unit 18 for performing an operation of selecting and displaying a place name related to a shooting location together with a date and time of a desired current location.

The MPU 14 has a data display processing unit 2
