Abstract

A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a controller configured to create a first set of thumbnail images for a first set of images among a plurality of images; and a display configured to display at least a portion of the first set of thumbnail images generated by the controller.

Claims

1. A mobile terminal, comprising:

a memory storing a plurality of images, the plurality of images divided into a plurality of sets of images, the plurality of images not having a plurality of corresponding thumbnail images; and

a controller configured to;

receive a command to display a plurality of thumbnail images corresponding to the plurality of images;

create a first set of thumbnail images corresponding to a first set of the plurality of images when the first set of thumbnail images are first to be displayed before creating thumbnail images for remaining images of the plurality of images;

display at least a portion of the created first set of thumbnail images;

store at least one of the first, second and third thumbnail images into the memory when the load of the controller is lower than a predetermined value before displaying the at least one of the first, second and third thumbnail images;

load the first set of thumbnail images when the first set of thumbnail images are not first to be displayed from the memory; and

display the loaded first set of thumbnail images,

wherein the second and third set of thumbnail images include at least one thumbnail image which is not displayed when the first set of the thumbnail images is displayed.

2. The mobile terminal of claim 1, wherein the second and third sets of thumbnail images include thumbnail images overlapping with some of the thumbnail images of the first set of thumbnail images.

3. The mobile terminal of claim 1, wherein the memory is further configured to store the plurality of images before the controller generates the first set of thumbnail images.

4. The mobile terminal of claim 1, wherein the memory is further configured to store the created first, second and third sets of thumbnail images.

5. The mobile terminal of claim 1, wherein the controller is further configured to create a new thumbnail image corresponding to a new image of the plurality of images, and to add the created new thumbnail image to the first set of the thumbnail images at a beginning or at an end of the first set of thumbnail images.

6. The mobile terminal of claim 1, wherein the memory is further configured to store header data corresponding to the plurality of thumbnail images, and

wherein the header data includes at least any one from an index about a thumbnail image corresponding to the header data, positions of the plurality of images corresponding to the thumbnail images, a position of the thumbnail image within the set group, information about whether the thumbnail image has been deleted, and information about whether the thumbnail image has been generated.

7. The mobile terminal of claim 1, wherein the controller is further configured to enter the mobile terminal into a low power mode, and to create the first, second and third set of thumbnail images only during the low power mode.

8. The mobile terminal of claim 1, wherein the controller is further configured to receive a deletion signal requesting at least one of the first set of thumbnail images be deleted, to stop displaying the selected at least one of the first set of thumbnail images, and to delete an image corresponding to the selected at least one of the first set of thumbnail images only after the mobile terminal enters a dim mode or a sleep mode.

9. The mobile terminal of claim 1, wherein each of the first, second and third sets of thumbnail images include six thumbnail images.

10. The mobile terminal of claim 9, wherein each of the first, second and third sets of thumbnail images are self-contained sets of thumbnail images and do not include a thumbnail image from another set.

11. The mobile terminal of claim 9, wherein the first set of thumbnail images include two thumbnail images from the second set of thumbnail images and two thumbnail images from the third set of thumbnail images.

12. A method of controlling a mobile terminal, the method comprising:

storing a plurality of images in a memory of the mobile terminal, the plurality of images divided into a plurality of sets of images, the plurality of images not having a plurality of corresponding thumbnail images;

receiving a command to display a plurality of thumbnail images corresponding to the plurality of images;

creating, via a controller of the mobile terminal, a first set of thumbnail images corresponding to a first set of the plurality of images when the first set of thumbnail images are first to be displayed before creating thumbnail images of the remaining images of the plurality of images;

displaying, via a display of the mobile terminal, at least a portion of the created first set of thumbnail images;

creating a second set and a third set of thumbnail images adjacent to the first set of thumbnail images in a specified arrangement list of the plurality of thumbnail images;

storing at least one of the first, second and third thumbnail images into the memory when the load of the controller is lower than a predetermined value before displaying the at least one of the first, second and third thumbnail images;

loading the first set of thumbnail images when the first set of thumbnail images are not first to be displayed from the memory; and

displaying the loaded first set of thumbnail images,

wherein the second and third set of thumbnail images include at least one thumbnail image which is not displayed when the first set of the thumbnail images is displayed.

13. The method of claim 12, wherein the second and third sets of thumbnail images include thumbnail images overlapping with some of the thumbnail images of the first set of thumbnail images.

14. The method of claim 12, further comprising:

storing, in the memory of the mobile terminal, the plurality of images before the generating step generates the first set of thumbnail images.

15. The method of claim 12, further comprising:

storing, in the memory of the mobile terminal, the created first, second and third sets of thumbnail images.

16. The method of claim 12, wherein the creating step further comprises creating a new thumbnail image corresponding to a new image of the plurality of images, and adding the created new thumbnail image to the first set of the thumbnail images at a beginning or at an end of the first set of thumbnail images.

17. The method of claim 12, further comprising:

storing, in the memory of the mobile terminal, header data corresponding to the plurality of thumbnail images,

wherein the header data includes at least any one from an index about a thumbnail image corresponding to the header data, positions of the plurality of images corresponding to the thumbnail images, a position of the thumbnail image within the set group, information about whether the thumbnail image has been deleted, and information about whether the thumbnail image has been generated.

18. The method of claim 12, further comprising:

entering the mobile terminal into a low power mode; and

creating the first, second and third set of thumbnail images only during the low power mode.

19. The method of claim 12, further comprising:

receiving a deletion signal requesting at least one of the first set of thumbnail images be deleted;

stop displaying the selected at least one of the first set of thumbnail images; and

deleting an image corresponding to the selected at least one of the first set of thumbnail images only after the mobile terminal enters a dim mode or a sleep mode.

20. The method of claim 12, wherein each of the first, second and third sets of thumbnail images include six thumbnail images.

21. The method of claim 20, wherein each of the first, second and third sets of thumbnail images are self-contained sets of thumbnail images and do not include a thumbnail image from another set.

22. The method of claim 20, wherein the first set of thumbnail images include two thumbnail images from the second set of thumbnail images and two thumbnail images from the third set of thumbnail images.
