Description

Image recording apparatus capable of recording image and position information

The present invention relates to an image recording apparatus such as a digital camcorder, and more particularly, data transmitted from an external communication terminal and a communication and external communication terminal through a communication module such as a Bluetooth module mounted inside or outside. An image recording apparatus capable of recording a recording medium on a recording medium.

In general, a digital camcorder has a function of a general video camera for photographing a subject and a video recorder for recording a photographed subject. Accordingly, a user may photograph a desired subject by using a digital camcorder and record it on a recording medium such as a magnetic tape. In addition, the user may check the subject again by playing the recording medium on which the photographed subject is recorded. In this case, an image of a subject reproduced from a recording medium is displayed through a liquid crystal display attached to a digital camcorder and a view finder. In addition, the digital camcorder can be connected to an external display device such as a television to check the reproduced image. The advantage of such a digital camcorder is that it is a portable photographing apparatus that can easily photograph a desired object anywhere, such as outdoors or a performance hall.

However, the digital camcorder has a problem in that it is impossible to check the position where the image displayed is displayed according to the playback of the recording medium. In order to solve this problem, recently, a method of checking the position of a captured image using a GPS (Global Positioning System) terminal capable of measuring position information has been proposed. In order to confirm the location information of the image photographed by using this method, it is possible to confirm the photographed position by matching the time of the recorded image when shooting with the digital camcorder and the time of the position information calculated by the portable GPS terminal.

However, this method is inconvenient to carry a portable GPS terminal every time to shoot in order to confirm the location information of the image taken by the digital camera. In addition, there is a problem that the portable GPS terminal needs a memory of sufficient capacity to store the position information calculated by the portable GPS terminal. Therefore, in order to confirm the location information of the image photographed by this method, there is a problem in that a portable GPS terminal having a high production cost is purchased.

In addition, in order to match the time of the location information stored in the portable GPS terminal with the time of the image recorded on the recording medium of the digital camcorder, it is cumbersome to check each time displayed on the screen of display devices such as personal computers and televisions. have. In addition, a user may be inconvenient to store and manage a recording medium on which an image photographed using a digital camcorder is recorded and a storage medium storing location information measured using a portable GPS terminal, respectively.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a digital camcorder that can solve the inconvenience of carrying a portable GPS terminal every time you shoot to confirm the location information of the image taken by the digital camcorder. .

Another object of the present invention for solving the problems described above, the respective playback to play the portable GPS terminal and the recording medium on which the photographed image is recorded on the display device to confirm the location of the image using the GPS terminal The present invention provides a digital camcorder capable of solving the inconvenience of having to check the position and orientation of a captured image by matching respective time information displayed according to playback by connecting devices.
