Abstract

A method of graphically resizing content displayed on a portion of a display screen of a mobile communication terminal is provided. The method comprises selecting a first area of an image graphically rendered on a display screen, content in the first area having a first set of dimensions and a first central point in a first relationship with boundaries of the first area; and graphically re-rendering the content in the first area on the display screen such that the content in the first area is displayed on the display screen in a second area of the screen having a second set of dimensions and a second central point having proportionally the first relationship with boundaries of the second area.

Claims

1. A method of graphically resizing content displayed on a portion of a display screen of a mobile communication terminal, the method comprising:

selecting a first area of an image graphically rendered on a display screen, content in the first area having a first set of dimensions and a first central point in a first relationship with boundaries of the first area; and

graphically re-rendering the content in the first area on the display screen such that the content in the first area is displayed on the display screen in a second area of the screen having a second set of dimensions and a second central point having proportionally the first relationship with boundaries of the second area.

2. The method of claim 1, wherein the second area is larger than the first area, in response to receiving a first command, and wherein the second area is smaller than the first area, in response to receiving a second command.

3. The method of claim 2, wherein the first command is a command to zoom-in on the first area, and the second command is a command to zoom-out of the first area.

4. The method of claim 3, wherein selecting the first area comprises drawing a geometric shape around the first area, wherein the first command is associated with a first direction selected to draw the geometric shape, and the second command is associated with a second direction selected to draw the geometric shape.

5. The method of claim 4, where in the second direction is opposite to the first direction.

6. The method of claim 5, wherein the shape is approximately an ellipse, the first direction is clockwise and the second direction is counter clockwise.

7. The method of claim 5, wherein level of zoom-in and zoom-out is controlled according to speed with which the geometric shape is drawn.

8. The method of claim 5, wherein level of zoom-in and zoom-out is controlled according to number of times the geometric shape is drawn.

9. The method of claim 7, wherein the level of zoom-in and zoom-out is doubled if speed of the speed with which the geometric shape is drawn is doubled.

10. The method of claim 8, the level of zoom-in and zoom-out is doubled if speed of the number of times the geometric shape is drawn is doubled.

12. The mobile communication terminal of claim 1, wherein the second area is larger than the first area, in response to receiving a first command, and wherein the second area is smaller than the first area, in response to receiving a second command.

13. The mobile communication terminal of claim 2, wherein the first command is a command to zoom-in on the first area, and the second command is a command to zoom-out of the first area.

14. The mobile communication terminal of claim 3, wherein selecting the first area comprises drawing a geometric shape around the first area, wherein the first command is associated with a first direction selected to draw the geometric shape, and the second command is associated with a second direction selected to draw the geometric shape.

15. The mobile communication terminal of claim 4, where in the second direction is opposite to the first direction.

16. The mobile communication terminal of claim 5, wherein the shape is approximately an ellipse, the first direction is clockwise and the second direction is counter clockwise.

17. The mobile communication terminal of claim 5, wherein level of zoom-in and zoom-out is controlled according to speed with which the geometric shape is drawn.

18. The mobile communication terminal of claim 5, wherein level of zoom-in and zoom-out is controlled according to number of times the geometric shape is drawn.

19. The mobile communication terminal of claim 7, wherein the level of zoom-in and zoom-out is doubled if speed of the speed with which the geometric shape is drawn is doubled.

20. The mobile communication terminal of claim 8, the level of zoom-in and zoom-out is doubled if speed of the number of times the geometric shape is drawn is doubled.

11. A mobile communication terminal comprising:

a touch-sensitive display screen;

a logic unit for selecting a first area of an image graphically rendered on a display screen, wherein content displayed in the first area have a first set of dimensions and a first central point in a first relationship with boundaries of the first area; and

a logic unit for graphically re-rendering the content in the first area on the display screen such that the content in the first area is displayed on the display screen in a second area of the screen having a second set of dimensions and a second central point having proportionally the first relationship with boundaries of the second area.
