The present invention relates to a digital image photographing device, and more particularly, to a digital image photographing device having a GPS function and a method for setting photographing location information thereof.

The GPS system is a GPS (Global Positioning System) called a satellite positioning system. It receives GPS signals from the 24 GPS satellites at an altitude of about 20,000 km around the earth and simultaneously transmits them to the ground at the same time every second. A GPS system provided in a vehicle having a function of displaying GPS data on a numerical map so as to three-dimensionally recognize a hardness, an altitude, and the like, has a navigation system that can receive location information service while driving.

The navigation system's GPS function can be navigated through a device equipped with a separate navigation function in a vehicle, a vehicle information terminal providing a GPS function along with traffic information or weather information, or a mobile phone that supports the GPS function. Function is available.

In general, the navigation system of the vehicle has a built-in navigation controller that can calculate the current position of the vehicle three-dimensionally by receiving the position measurement radio wave transmitted from the GPS satellite, and in addition to the navigation controller in the area where the vehicle is operating And a database storing geographic information on roads and traffic facilities, and a display device for displaying information obtained from the navigation controller and the database to the driver.

Such a navigation system stores road maps taken from satellites in a predetermined storage medium as a database, and displays the current driving position on a road map, and sets a desired target point for the driver. Search for the route and display the shortest route on the display to make the vehicle convenient to travel. However, an expensive control chip such as a CPU (Central Processor Unit) is used as a controller of the navigation system, but it has a disadvantage in that its utilization is low because it merely performs a navigation function.

Recently, there is a digital camera as a photographing device that captures images and stores them digitally. In addition, there are various types of portable digital devices such as a portable telephone equipped with a camcorder and a camera, an electronic notebook equipped with a camera, and a personal data assistant Shooting equipment is on the market.
