Abstract

A data recording unit in use with a camera for recording information data, obtained through a GPS receiver, on a photographing film. The data recording unit includes: a selector for selecting a geodetic system from plural geodetic systems; a data converter for converting position information data, obtained through the GPS receiver, to converted position information data in the geodetic system which is selected by the selector; and a printing LED for recording the converted position information data on the photographic film together with images photographed by the camera.

Claims

1. A data recording unit for use with a camera for recording on a recording medium, information data obtained by a GPS receiver, comprising:

selection means for selecting a geodetic system from a plurality of geodetic systems;

data conversion means for converting position information data, obtained by said GPS receiver, to converted position information data in the selected geodetic system; and

recording means for recording said converted position information data on said recording medium together with images photographed by said camera.

2. The data recording unit of claim 1, further comprising:

geodetic system information outputting means for outputting geodetic system information corresponding to the selected geodetic system, said recording means recording on said recording medium said geodetic system information together with said converted position information data.

3. The data recording unit of claim 1, further comprising:

display means for displaying at least one of said selected geodetic system and said converted position information data.

4. A data recording unit for use with a camera for recording on a recording medium information data obtained by a GPS receiver, comprising:

first outputting means for outputting position information data and GPS time information according to signals received by said GPS receiver;

setting means for setting area information;

time information conversion means for converting said GPS time information to local time corresponding to said set area information;

second outputting means for outputting said local time;

data conversion means for converting said position information data to converted position information data expressed in a geodetic system corresponding to said set area information; and

recording means for recording on said recording medium, said local time and said converted position information data together with images photographed by said camera.

5. The data recording unit of claim 4, further comprising:

display means for displaying said local time and said converted position information data when said area information is set by said setting means, and for displaying time and position information data corresponding to a geodetic system of WGS-84 when said area information is not set by said setting means.

6. A data recording unit in use with a camera for recording on a recording medium, information data obtained by a GPS receiver, comprising:

first outputting means for outputting position information data according to signals received by said GPS receiver,

setting means for setting at least one of area information and a geodetic system;

calculation means for calculating difference between said position information data and area data corresponding to at least one of said set area information and said set geodetic system, said calculation means generating a

difference signal corresponding to the calculated difference; and

warning means for issuing a warning when said difference signal is greater than a predetermined value.

7. The data recording unit of claim 6, wherein said warning means includes at least one of display means for displaying a warning message and generating means for generating a warning sound.

8. The data recording unit of claim 6, wherein said warning means includes prohibition means for prohibiting a photographing operating of said camera.
