Abstract

The present invention relates to the display of multi-frame-based information on devices such as mobile terminal devices, wherein a possible definition of “a frame” is a display area of an application that is scrollable, if the whole content can not be displayed at once. More specifically, the present invention relates to a method and a device to select one or more frames of a plurality of received or retrieved frames to be displayed as an active frame. The method comprises determining for each frame the total data content and the displayed data content, calculating for each of said frames a ratio of said determined data content and said determined displayed data content, and selecting the frame with the largest ratio for display as an active frame.

Claims

1. Method for automatically selecting a frame to be displayed as an active frame on a device capable of displaying one or more frames or a portion of a frame, comprising:

determining for each frame a total data content and a displayed data content,

calculating for said each frame a ratio of said determined data content and said determined displayed data content, and

selecting a frame with a largest ratio for display as said active frame.

2. Method according to claim 1 further comprising:

selecting at least one of said frames with the largest ratio to be displayed as an active frame, if more than one of said frames are determined with a same largest ratio.

3. Method according to claim 1 further comprising:

re-scaling said frames to a normalized frame size prior to determining said data contents.

4. Method according to claim 1 further comprising:

pre-selecting text based frames of said frames prior to determining said data contents.

5. Method according to claim 1 further comprising:

suppressing the displaying of one or more frames with smallest calculated ratios.

6. Method according to claim 1 further comprising:

sorting said frames for display according to said calculated ratios.

7. Method according to claim 1, wherein said method is performed by a web browser program.

8. Method according to claim 1, further comprising receiving at least two frames for display.

9. Computer program product comprising program code means stored on a computer readable medium for carrying out the method of claim 1, when said program product is run on a device.

10. Terminal device capable of automatically selecting a frame to be displayed as an active frame, comprising:

a data interface,

a central processing unit,

a display,

a user interface,

wherein said central processing unit is connected to said data interface, to said user interface, and to said display,

wherein said data interface is configured to receive data representing data frames, and said central processing unit is configured to provide said display unit with data that can be displayed as frames,

characterized by an evaluation component connected to said central processing unit, wherein said evaluation component is configured to determine for each received frame an amount of total data content and a displayed data content, to calculate for each of said frames a ratio of said data content and said displayed data content, and to control said central processing unit to select frames with a largest ratio for display as an active frame.

11. Terminal device according to claim 10, wherein said terminal device is a mobile terminal device.

12. Terminal device according to claim 10, further comprising a cellular telephone.

13. Terminal device according to claim 10, further comprising a personal digital assistant.

14. Terminal device according to claim 10, wherein said data interface is a radio interface to a communication network.
