Abstract

The present invention relates to at least one image section which is represented according to a zoom factor selected from a number of different zoom factors. Either the represented image section is changed when the zoom factor is lower than a zoom threshold value, or a marker representation superimposing the image section is displaced when the zoom factor is higher than a zoom threshold value, via input elements.

Claims

1. A method for navigating within a screen having an image, comprising:

displaying at least a portion of the image according to a zoom factor having a threshold value;

changing the displayed image segment using an input element if the zoom factor is less than the threshold value;

setting the displayed image segment when the zoom factor is greater than the threshold value; and

tracking the input element on the set image segment and changing the image segment when the input element crosses a corresponding border zone of the image segment.

2. The method of claim 1, wherein the portion comprises one or more pixels.

3. A method for navigating within an image, the method comprising:

displaying at least one image segment according to a zoom factor;

changing the displayed image segment using an input element if the zoom factor is less than a zoom threshold value;

setting the displayed image segment when the zoom factor is greater than the zoom threshold value; and

moving a marking point corresponding to the set image segment using the input element when the zoom factor is greater than the zoom threshold value and without changing the image segment being displayed when the marking point is not located in a corresponding border zone of the image segment and changing the image segment when the marking point is located in a corresponding border zone of the image segment.

4. A method for navigating within an image, the method comprising:

displaying at least one image segment within the image, wherein the image segment is subject to a zoom factor having a threshold value;

changing the displayed image segment using an input element if the zoom factor is less than the threshold value;

setting a displayed image segment within the image when the zoom factor is greater than the threshold value, wherein the modified image segment comprises a corresponding border zone;

monitoring at least one input from an input element relative to the modified image segment;

changing the modified image segment when the at least one input is located in the corresponding border zone of the image segment.

5. The method of claim 4, wherein the displayed image segment is modified.
