Abstract

A digital multimedia playback apparatus and a control method thereof in which a user starts touching, on a touch screen, one of an item and a function icon ends touching the other one of the item and function icon to control the items and functions displayed thereon. The digital multimedia playback apparatus includes a touch screen to change the state of the item to the state that corresponds to the function icon; thus, the user can more easily edit files or the like.

Claims

1. A digital multimedia playback apparatus, comprising:

a display unit comprising a touch screen to display a list of items and a function icon; and

a controller to change a state of an item of the list to a state corresponding to the function icon, if a first user command is input through the touch screen to use the item and the function icon to apply the function to the item.

2. The digital multimedia playback apparatus of claim 1, wherein the digital multimedia playback apparatus is a photographing apparatus.

3. The digital multimedia playback apparatus of claim 1, wherein the first user command input starts with touching one of the item and the function icon and ends with touching the other one of the item and the function icon.

4. The digital multimedia playback apparatus of claim 1, wherein the function icon is selectable between a trash icon, a protection icon, and a playlist icon.

5. The digital multimedia playback apparatus of claim 4, wherein,

if the function icon is the trash icon, the controller deletes the touched item from a storage unit in which the touched item is stored;

if the function icon is the protection icon and if a command to delete the list is input, the controller deletes other items of the list, excluding the touched item; and

if the function icon is the playlist icon, the controller stores the touched item in a storage unit for a playlist.

6. The digital multimedia playback apparatus of claim 1, wherein,

if the list is an icon list and if a user command input starts by touching one of an item of the icon list and the function icon and ends by touching the other one of the item and the function icon, the controller exchanges on the display unit the position of the touched item with the position of the function icon, and controls the touched item so that the touched item operates as a function icon.

7. The digital multimedia playback apparatus of claim 1, wherein,

if a second user command is input by touching the function icon, the controller controls the display unit to display the items having the state that corresponds to the function icon.

8. The digital multimedia playback apparatus of claim 1, wherein the controller determines a touch start point of the first user command and a touch end point of the first user command and compares the touch start point to the touch end point.

9. The digital multimedia playback apparatus of claim 8, wherein,

if the touch start point and the touch end point are determined to be in different fields, the controller controls the display unit to display a confirmation message to request confirmation of changing the state of the item.

10. The digital multimedia playback apparatus of claim 9, wherein the controller changes the state of the item and displays a changed list according to the changed state of the item on the display unit if the change of the state of the item is confirmed.

11. A control method of a digital multimedia playback apparatus comprising a touch screen, the method comprising:

displaying a list of items and a function icon on the touch screen; and

changing a state of an item of the list to a state corresponding to the function icon if a first user command is input on the touch screen using the item and the function icon to apply the function to the item.

12. The control method of claim 11, wherein the digital multimedia playback apparatus having the touch screen is a photographing apparatus.

13. The control method of claim 11, wherein the first user command input starts with touching one of the item and the function icon and ends with touching the other one of the item and the function icon.

14. The control method of claim 11, wherein the function icon is selectable between a trash icon, a protection icon, and a playlist icon.

15. The control method of claim 14, wherein,

if the function icon is the trash icon, the changing comprises deleting the touched item from a storage unit in which the touched item is stored;

if the function icon is the protection icon and if a command to delete the list is input, the changing comprises deleting other items of the list, excluding the touched item; and

if the function icon is the playlist icon, the changing comprises storing the touched item in a storage unit for a playlist.

16. The control method of claim 11, wherein,

if the list is an icon list and if a user command input starts by touching one of an item of the icon list and the function icon and ends by touching the other one of the item and the function icon, the changing comprises exchanging the position of the touched item with the position of the function icon, and controlling the touched item so that the touched item operates as a function icon.

17. The control method of claim 11, wherein, if a second user command is input by touching the function icon, the changing comprises controlling the display unit to display the items having the state that corresponds to the function icon.

18. A control method of a video camcorder comprising a touch screen, the method comprising:

displaying a list of items and function icons;

detecting a touch on the touch screen;

determining whether a touch start position and a touch end position are in a same field;

changing a state of an item of the list to a state corresponding to one of the function icons if the determined fields are different; and

changing a state of one of the function icons if the fields are the same.

19. The control method of claim 18, wherein, if the touch start position is in a first area indicating a first function icon, and the touch end position is in a second area indicating a second function icon, the state of the first function icon is changed so that the first function icon is displayed in the second area, and the state of the second function icon is changed so that the second function icon is displayed in the first area.

20. A control method of a digital multimedia playback apparatus comprising a touch screen, the method comprising:

displaying function icons and list items on the touch screen;

detecting a touch on the touch screen;

determining a touch start position and a touch end position; and

changing a state of an item of the list items according to a function of one of the function icons when the touch start position is determined to be in an area of the one of the function icons and the touch end position is determined to be in an area of the item of the list items.

21. A digital multimedia playback apparatus, comprising:

a display unit comprising a touch screen to display list items and function icons; and

a controller to change a state of an item of the list items according to a function of one of the function icons when a touch start position is determined to be in an area of the one of the function icons and a touch end position is determined to be in an area of the item of the list items.
