Abstract

A user interface includes a controller which is configured to display image data, receive input indicating a touch area corresponding to at least a portion of the image data, perform a zoom-in action on the at least portion of the image data and to display at least a portion of the zoomed-in portion in addition to the remainder of the image data in response thereto.

Claims

1. An apparatus comprising a controller, wherein said controller is arranged to:

display image data;

receive input indicating a touch area corresponding to at least a portion of said image data;

perform a zoom-in action on the at least portion of said image data; and

to

display at least a portion of the zoomed-in portion in addition to the remainder of the image data in response thereto.

2. An apparatus according to claim 1, wherein said controller is configured to determine said touch area to also comprise a surrounding area.

3. An apparatus according to claim 1, wherein the controller is configured to determine a transition area and to perform a gradual zoom-in action on said transition area and to also display said transition area, wherein the gradual zoom-in action applies a varying magnification factor.

4. An apparatus according to claim 1, wherein said controller is configured to display said zoom-in action as an animation.

5. An apparatus according to claim 1, wherein the controller is configured to receive an input indicating a position falling inside the touch area and a direction and in response thereto display the zoomed-in portion of the image data as translated in the direction as indicated by the input.

6. An apparatus according to claim 1, wherein said controller is configured to receive said input through a touch display.

16. An apparatus according to claim 1, wherein said touch area comprises a path drawn on a display.

17. An apparatus according to claim 1, wherein said controller is configured to provide an indication that the touch area has been registered.

18. An apparatus according to claim 3, wherein the zoomed-in portion is smoothly embedded in the image data without sharp edges.

19. An apparatus according to claim 4, wherein said animation is performed in real-time.

7. (canceled)

8. A user interface comprising a controller configured to:

display image data;

receive input indicating a touch area corresponding to at least a portion of said image data;

perform a zoom-in action on the at least portion of said image data; and

to

display at least a portion of the zoomed-in portion in addition to the remainder of the image data in response thereto.

9. A computer readable medium comprising at least computer program code for controlling an apparatus, said computer readable medium comprising:

software code for displaying image data;

software code for receiving input indicating a touch area corresponding to at least a portion of said image data;

software code for performing a zoom-in action on the at least portion of said image data; and

software code for displaying at least a portion of the zoomed-in portion in addition to the remainder of the image data in response thereto.

10. A method for use in an apparatus comprising at least a processor, said method comprising:

displaying image data;

receiving input indicating a touch area corresponding to at least a portion of said image data;

performing a zoom-in action on the at least portion of said image data; and

displaying at least a portion of the zoomed-in portion in addition to the remainder of the image data in response thereto.

11. A method according to claim 10, further comprising determining said touch area to also comprise a surrounding area.

12. A method according to claim 10, further comprising determining a transition area and performing a gradual zoom-in action on said transition area and also displaying said transition area, wherein the gradual zoom-in action applies a varying magnification factor.

13. A method according to claim 10, further comprising displaying said zoom-in action as an animation.

14. A method according to claim 10, further comprising receiving an input indicating a position falling inside the touch area and a direction and in response thereto display the zoomed-in portion of the image data as translated in the direction as indicated by the input.

20. A method according to claim 10, wherein said touch area comprises a path drawn on a display.

21. A method according to claim 10, further comprising providing an indication that the touch area has been registered.

22. A method according to claim 12, wherein the zoomed-in portion is smoothly embedded in the image data without sharp edges.
