Landmark search system for digital camera, map data, and method of sorting image data
First Claim
1. A landmark search system comprising:
- a digital camera comprising a position data obtaining device for obtaining position data of a camera position at which an image is captured, and a data storage device for storing said position data in association with image data of the captured image;
a map data storage device storing map data, said map data comprising area data of divisional areas which are provided by dividing a map area at regular intervals of latitude and longitude, and place data prepared for each of said divisional areas, said place data including data of landmarks located in each of said divisional areas; and
a search device that searches said map data based on said position data, to select one divisional area that includes the camera position, and thereafter retrieve said place data for the selected divisional area, to determine a landmark that corresponds to the camera position.

Abstract
In a camera location landmark search system, when an image is captured by a digital camera, a GPS calculator calculates position data indicating a camera position. The position data and image data of the captured image are memorized in association with each other. Map data is divided at regular intervals of latitude and longitude into a lot of areas. Based on the position data, a divisional area including the camera position is selected with reference to a divisional area index table of the map data, and landmark data prepared for the determined divisional area are retrieved from a landmark data table of the map data. Based on the landmark data, a landmark corresponding to the camera position is determined, and the landmark name is memorized in association with the image data. The image data as sorted according to the landmark names may be displayed with the landmark names.
