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.

[0010] A measurement error on a map based on position information measured by the GPS receiver 12 together with the place name stored in the map database 16, for example, the place information subdivided into building names, park names, etc., divided in units of 10 m. It can also be stored. In this case, a plurality of information recording media storing a rough city name and information such as a building name and a park name corresponding to the city name 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 photographing place, together with a date and time of a desired current point.

The MPU 14 has a data display processing unit 2
2 are connected, and the data display processing unit 22
It is set to the MPU 14 from the operation unit 18, and the date and time information of the desired current point from the GPS receiver 12 fetched by the MPU 14, or the shooting location fetched from the MPU 14 by searching the map database 16. The place name (country name, city name, building name, park name, etc.) is superimposed based on the setting of the operation unit 18 and the video recording processing unit 20 is used.
To generate and send out a signal for recording.

Next, the operation of the above configuration will be described. In the GPS receiver 12, three or four GPS radio waves Wa, Wb, W
c, (Wd) is received, and the position information of the latitude, longitude, altitude, and time of the reception position is output. This information is
14.

Further, the MPU 14 is provided from the operation unit 18 in advance.
In this case, it is set so that any or all of the contents to be recorded together with the photographed image by the image recording processing unit 20, that is, the photographing place name, the photographing date, and the photographing local time are taken in, and the control processing is performed. A photographing signal is supplied from the CCD photographing device 10 to the video recording processing unit 20 and is recorded on the attached magnetic tape.

In response to a simultaneous recording instruction from the operation unit 18, the MPU 14 searches for the place name stored in the map database 16 based on the longitude and latitude position information measured by the GPS receiver 12, and fetches the place name. . At the same time, the date, time, and time of the current location are fetched and supplied to the data display processing unit 22, and the information (signal) of the location name, the date, time, and time of the current location can be superimposed by the video recording processing unit 20. The signal is processed and output. The output signal from the data display processing unit 22 is supplied to the video recording processing unit 20, where it is superimposed on the imaging screen and recorded on the magnetic tape.
