Abstract

An image display control apparatus enables determination as to whether or not an image file includes position information, and further, facilitates checking of positioning method of the position information. Accordingly, in the apparatus, positioning information in the image file is analyzed, and it is determined whether or not a positioning method indicating a positioning method for the position information is described. Further, when it is determined that the positioning method is described, the type of the positioning method is determined. Then an icon for discrimination of the presence/absence of positioning method and type of the positioning method is superimposed on a thumbnail of an image indicated with a corresponding image file.

Claims

1. An image display control apparatus which performs control to display a list of image files stored in a storage unit, comprising:

a determination unit configured to analyze each image file stored in the storage unit, and determine whether or not the image file includes position information indicating a position and whether or not the image file includes positioning method information indicating a positioning method for the position; and

a display control unit configured to, upon display of the list of image files stored in the storage unit, in accordance with the result of determination by the determination unit, display an image file including the position information in an appearance distinguishable from an image file not including the position information, while displaying a type of the positioning method indicated with the positioning method information in the image file including the position information, in a distinguishable appearance.

2. The image display control apparatus according to claim 1, wherein the display control unit displays, regarding the image file not including the position information, a thumbnail of an image represented with the image file, while regarding the image file including the position information, superimposes an icon corresponding to the type of the positioning method indicated with the positioning method information on a thumbnail of an image represented with the image file.

3. The image display control apparatus according to claim 2, wherein when the determination unit determines an image file including first positioning method information and second positioning method information as the positioning method information, the display control unit superimposes an icon, having a first size, corresponding to the type of the positioning method indicated with the first positioning method information, and an icon having a second size smaller than the first size, corresponding to the type of the positioning method indicated with the second positioning method information, on the thumbnail of the image represented with the determined image file.

4. The image display control apparatus according to claim 1, further comprising:

a designation unit configured to designate one of the image files displayed in list form by the display control unit; and

a position information display unit configured to, when the image file designated by the designation unit includes the position information, display detailed information of the position information in a balloon form.

5. The image display control apparatus according to claim 1, further comprising:

a designation unit configured to designate one of the image files displayed in list form by the display control unit;

a menu display unit configured to, when the image file designated by the designation unit includes the position information and a predetermined operation is performed, display an editing menu including a plurality of editing items for the position information; and

an editing unit configured to, when one of the displayed editing items is designated, perform editing processing corresponding to the designated editing item with respect to the position information of the image file.

6. The image display control apparatus according to claim 2, further comprising:

a map database to output a map image including a position indicated with a given position information, in accordance with the position information;

a display device having a list display region to display thumbnails of a plurality of image files in a scrollable form and a map region to display a map image; and

a map display unit configured to calculate a mean position from image files having the position information, among the image files stored in the storage unit, obtain a map image, using the mean position as a key, from the map database, and display the map image in the map region,

wherein the display control unit displays the thumbnails of the respective image files in the list display region, and further, regarding an image file having the position information, displays a predetermined icon in a position indicated with the position information in the map image.

7. A control method for an image display control apparatus which displays a list of image files stored in a storage unit, comprising:

determining, by analyzing each image file stored in the storage unit, whether or not the image file includes position information indicating a position and whether or not the image file includes positioning method information indicating a positioning method for the position; and

displaying, upon display of the list of image files stored in the storage unit, in accordance with the result of determination, an image file including the position information in an appearance distinguishable from an image file not including the position information, while displaying a type of the positioning method indicated with the positioning method information in the image file including the position information, in a distinguishable appearance.

8. A non-transitory computer-readable storage medium storing a computer program read and execute by a computer to cause the computer to perform control method, the control method comprising:

determining, by analyzing each image file stored in a storage unit, whether or not the image file includes position information indicating a position and whether or not the image file includes positioning method information indicating a positioning method for the position; and

displaying, upon display of the list of image files stored in the storage unit, in accordance with the result of determination, an image file including the position information in an appearance distinguishable from an image file not including the position information, while displaying a type of the positioning method indicated with the positioning method information in the image file including the position information, in a distinguishable appearance.
