Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording system for recording image information, a recording device used in this system, a recording medium on which information is recorded by this recording system, a reproducing system for reproducing this recording medium, and a reproducing system. Regarding the device.

[0002]

2. Description of the Related Art For example, when an image is picked up using a video tape recorder with a built-in camera (hereinafter referred to as a VTR with a built-in camera), the user notes the picked-up date and time, the picked-up place where the picked-up image is taken, the picked-up contents, and the like. And record it.
Then, the memoized information is written on, for example, a label sticker, and a video recording an image of the label sticker is attached to a case in which a tape is stored.

By doing so, for example, when a video tape on which an image taken several years ago is recorded is reproduced, the reproduced image is confirmed by checking the description of the label sticker attached. It is possible to know when, where and how the image was taken.

[0004]

By the way, as described above, it is very troublesome to record such information each time the image pickup date, the image pickup place, the image pickup contents, etc. change.

Further, when the user does not have a memo paper or a pen, he forgets to leave the recording itself or remembers the user's memory such as the shooting location even if he wants to keep the recording at the shooting location later. In some cases, such as when the image is ambiguous, it may not be possible to record an accurate record corresponding to the captured image.

Further, when images taken at a plurality of different places are continuously recorded on one video tape, such as when traveling, etc., the images taken at each image taking place and the images left in the memo are taken. Correspondence with records such as places may be lost. For example, if records such as Hokkaido and Aomori remain as the image capturing location, no one other than the image capturing person may know whether the reproduced image is the image captured in Hokkaido or the image captured in Aomori. Things happen.

In view of the above, according to the present invention, information such as an image pickup location of an image picked up and recorded is accurately recorded at the time of picking up the image, and at the time of reproducing this image, an image corresponding to the reproduced image is picked up. An object of the present invention is to provide a recording system, a recording device, a recording medium, and a reproducing device that can accurately and surely provide information such as a location.

[0008]

In order to solve the above problems, a recording system according to the present invention includes a position detecting device for detecting an image pickup position at the time of image pickup, an azimuth detecting device for detecting an image pickup direction at the time of image pickup, and an image pickup device. And a recording device that records image information captured by the image capturing device, image capturing position information from the position detecting device, and image capturing orientation information from the orientation detecting device on a recording medium. , Are included.

In the recording system according to the present invention,
The imaged image, the imaging position at the time of imaging this image, and the imaging direction at the time of imaging are recorded in the same recording medium. As a result, the imaged image and the corresponding imaging position and imaging direction are recorded without the user's hands.

Further, the reproducing system according to the present invention reproduces the recording medium on which the image information and the image capturing position information and the image capturing direction information when the image information is captured are recorded, and the image information and the image capturing position are recorded. A reproduction device that outputs information and the imaging direction information, a map information generation device that generates map information, and a map information acquisition device that acquires map information to be displayed from the map information generation means based on the imaging position information. And a position / direction display indicating the image capturing position and the image capturing direction on the map formed based on the displayed map information acquired by the map information acquiring unit, based on the image capturing position and the image capturing direction information. Then, a synthesizing device for synthesizing on the map, an image based on the image information is displayed on the first screen, and the map synthesized by the synthesizing means is displayed. Characterized by comprising a display device and to be displayed on the second screen.

In the reproducing system according to the present invention,
When the recording medium on which the image information, the image pickup position information, and the image pickup direction information is recorded is reproduced in the reproducing device, the image information and the other image pickup position information and image pickup direction information are output. Then, the map information according to the image pickup position information is acquired from the map information generation device by the map information acquisition device, and the image pickup position information and the image pickup direction information are displayed on the map formed by the acquired map information. And depending on
The position / direction display indicating these is combined. Then, a map in which the image based on the image information and the position / direction display are combined is displayed on the screen. As a result, the user is notified of where and in which direction the image displayed by the image information was captured.
