2. Description of the Related Art Hitherto, it has been practiced to superimpose and record a photographing date and a photographing time on image information photographed by a video camera or a camera. However, it is often difficult to specify the shooting location or what the shot subject is when only the information is used to reproduce the image later.

[0003] Therefore, as a method of specifying an image shooting location,
JP-A-7-123348 discloses a GPS (Glob).
There is disclosed an apparatus that acquires information on a shooting position by using an al Positioning System function and synchronizes the information with image information. In the method, it is disclosed that not only the GPS data is displayed and recorded, but also that the map data is separately prepared and displayed and recorded so that the photographer can easily understand it. Furthermore, image search using position information is also possible.

[0004]

In the prior art, even when an image is taken by a video camera or a camera, the subject still has to be photographed or recorded by sound, such as a board on which information on the subject is written. Information on the photographed subject could not be superimposed and recorded.

On the other hand, subject information is prepared in map data disclosed in JP-A-7-123348.
Display and recording using GPS data are conceivable. However, the error of the GPS data is several hundred meters at present, and DGPS (Differential GPS)
Even if the method is used, an error of several tens of meters still occurs. Therefore, in most sightseeing spots and amusement parks, most of the sites fall within the error range, and it cannot be said that the environment in which the subject information can be obtained is very large. Eventually, when an image taken at a sightseeing spot or the like is viewed later, there is a problem that the place where the image was taken is known but the photographed subject cannot be remembered. In addition, when shooting indoors, GPS cannot be used, and even the position information cannot be obtained by the above technology.

Accordingly, the present invention has been made to solve the above-mentioned problems, and information of a photographed subject is superimposed and displayed on image information photographed by an image pickup device such as a video camera, and recorded. It is an object to provide a possible information transmission system.
