[0002]

2. Description of the Related Art In recent years, as shooting with a video camera has become popular, there is a demand for easy management and editing of tapes after shooting. The conventional video tape editing apparatus employs a method of finding a specific location on the tape by using a time code recorded on the tape together with an image, as represented by an editing controller for broadcasting. For example,
It is introduced on pages 91-94 of the March issue of "Videocom" issued by the foundation AVCC in 1990.

The search function of the conventional video tape editing apparatus will be described below. FIG. 5 is a block diagram of a part for realizing the search of the conventional video tape editing apparatus.

In the figure, 501 is a time code input means, 502 is a search control means, 503 is a video tape recording / reproducing means, and 504 is a monitor.

The operation of the video tape editing apparatus having the above structure will be described below.

The user inputs the time code corresponding to the image to be searched from the time code input means 501. For example, when searching for a video shot at Osaka Castle in January 1990, the user searches the recording table or the like to find out which time code part of the video is recorded, and inputs the time code. To do. Search control means 50
2 adds the input time code as a parameter to the cue command of the video tape recording / reproducing means 503 and sends it to the video tape recording / reproducing means 503. The video tape recording / reproducing means 503 searches the time code recorded on the tape in accordance with the command, finds a necessary portion, and then stops. The user confirms the video on the monitor 504, and a series of search operations is completed.

[0007]

However, in the above configuration, when searching a video image of a certain place,
Correspondence between the shooting location and the time code of the tape requires a human work such as a table look-up, and it takes a lot of time, and there is a problem that an error is likely to occur.

The present invention solves the above-mentioned conventional problems, and provides a video tape retrieval apparatus which makes it easy to retrieve a tape according to a photographing location after photographing.

The present invention corresponds to a photographing apparatus for recording photographed position information on a tape, and using the position information recorded on the tape, it is easy to search the tape for a portion corresponding to a designated photographing position range. The purpose is to make it possible to provide a device to be used in the above.

[0010]

In order to achieve this object, a video tape retrieval apparatus of the present invention comprises a display means for displaying a map and characters, and a range designated on the map displayed on the display means. Range input means for inputting, position data conversion means for converting the specified range on the display means into the format of the position data recorded on the tape, and a portion corresponding to the specified position data is searched from the video tape. A video tape search means and a video tape recording / playback means controlled by the video tape search means are provided.

Further, the video tape retrieval apparatus of the present invention is
Display means for displaying a map and characters, range input means for inputting a range specified on the map displayed on the display means, and position data recorded on a tape for the specified range on the display means. Position data converting means for converting into a format, video tape searching means for searching the video tape for a portion corresponding to the designated position data, video tape recording / reproducing means controlled by the video tape searching means, and Information display means for displaying information of the recorded video tape.

[0012]

With the above-described structure, the video tape retrieval apparatus of the present invention searches for the portion photographed in the area designated by the user on the map using the tape in which the photographing location is recorded as data together with the image. ..

Further, the video tape retrieval apparatus of the present invention is
With the above-described configuration, the information attached to the portion photographed in the area designated by the user on the map is displayed using the tape on which the photographing location and the associated information are recorded together with the video as data.
