Image display device and computer-readable medium

Abstract

An image display device includes: an image display unit that displays a list of images each including information related to a position of photography; a selection unit that selects at least one image from among the images; a photography position information acquisition unit that acquires information related to the position of photography; a specification unit that specifies a map server based on the information related to the position of photography; a requesting unit that transmits to the specified map server the information related to the position of photography, and that requests the map server to transmit map data for a range that includes the position of photography; a reception unit that receives the map data transmitted from the map server; and a display control unit that displays a map based on the received map data, and displays information specifying the position of photography upon the map.

1 . An image display device, comprising:
 an image display unit that displays a list of images each including information related to a position of photography;   a selection unit that selects at least one image from among the images displayed by the image display unit;   a photography position information acquisition unit that acquires information related to the position of photography of the image selected by the selection unit;   a specification unit that specifies a map server based on the information related to the position of photography acquired by the photography position information acquisition unit;   a requesting unit that transmits to the map server specified by the specification unit the information related to the position of photography acquired by the photography position information acquisition unit, and that requests the map server to transmit map data for a range that includes the position of photography;   a reception unit that receives the map data transmitted from the map server; and   a display control unit that displays a map based on the map data received by the reception unit, and displays information specifying the position of photography of the image selected by the selection unit upon the map.   
   
   
       2 . An image display device according to  claim 1 , wherein:
 the specification unit specifies a country in which the image was photographed based on the information related to the position of photography of the image, and specifies a map server installed in that specified country as a map server from which map data is to be acquired.   
   
   
       3 . An image display device according to  claim 2 , wherein:
 the information specifying the position of photography is latitude and longitude information for the position of photography; and   the specification unit specifies the country in which the image was photographed by employing a conversion table for converting the latitude and longitude information for the position of photography into a country code for specifying a country.   
   
   
       4 . An image display device according to  claim 2 , wherein:
 the information specifying the position of photography is latitude and longitude information for the position of photography; and   the specification unit specifies the country in which the image was photographed by transmitting the latitude and longitude information for the position of photography over the Internet to a conversion service that converts the latitude and longitude information for the position of photography into a country code for specifying a country, and that returns the country code.   
   
   
       5 . An image display device according to  claim 2 , wherein:
 when the selection unit has selected a plurality of images, the specification unit specifies, as a map server from which map data is to be acquired, a map server in a country, among countries of photography of the plurality of images, in which the greatest number of images were photographed.   
   
   
       6 . An image display device according to  claim 1 , wherein:
 when a geodetic system of the map server is different from a geodetic system of the information related to the position of photography included in the image, the requesting unit requests the map server to transmit map data, after having converted the geodetic system of the information related to the position of photography included in the image, to the geodetic system of the map server.   
   
   
       7 . An image display device according to  claim 1 , further comprising:
 a notification unit that, when the image selected by the selection unit does not include the information relating to the position of photography, notifies a user a fact that the image does not include the information relating to the position of photography.   
   
   
       8 . An image display device according to  claim 7 , wherein:
 when the notification unit has notified the fact, the requesting unit requests a map server that is set in advance to transmit map data for a range that is set in advance.   
   
   
       9 . An image display device according to  claim 1 , wherein:
 when no response has been received from the map server specified by the specification unit after a predetermined time has elapsed from when the server was requested to transmit map data, the requesting unit requests a map server installed in a country that is different from a country of the map server specified by the specification unit to transmit map data.   
   
   
       10 . A computer-readable medium having computer executable instructions for performing steps, the steps comprising:
 an image display step of displaying a list of images each including information related to a position of photography;   a selection step of selecting at least one image from among the images displayed by the image display step;   a photography position information acquisition step of acquiring information related to the position of photography of the image selected by the selection step;   a specification step of specifying a map server based on the information related to the position of photography acquired by the photography position information acquisition step;   a requesting step of transmitting to the map server specified by the specification step the information related to the position of photography acquired by the photography position information acquisition step, and that requests the map server to transmit map data for a range that includes the position of photography;   a reception step of receiving the map data transmitted from the map server; and   a display control step of displaying a map based on the map data received by the reception step, and displays information specifying the position of photography of the image selected by the selection step upon the map.
