Abstract

A novel method and apparatus for controlling a display of an electronic device is provided. In an embodiment, the device is a portable electronic device with the combined features of wireless email and telephony. The portable electronic device also includes a camera. The device includes a trackball which can be used to control the image shown in the viewfinder when the device is being used as a camera.

Claims

1. A method for controlling the display of a portable electronic device having a camera function;

the portable electronic device including a light-sensitive transducer for receiving a first image and a trackball for use as a user-input device;

the method comprising;

setting a default zoom level;

activating a viewfinder by generating a second image on the display that corresponds to the first image;

the second image having a field of view that corresponds to the default zoom level;

receiving rolling input from the trackball;

the input representing an instruction either to zoom-in to or zoom-out from the field of view;

adjusting the zoom level based on whether the instruction indicated zoom-in or zoom-out; and

regenerating the second image, on the viewfinder, with an enlarged or reduced field of view according to the zoom level from the adjusting.

2. The method of claim 1 wherein the device includes at least one additional function in addition to the camera function;

the method further comprising, prior to the setting, receiving a request to activate the camera function.

3. The method of claim 2 wherein the at least one additional function includes at least one of wireless telephony and wireless email.

4. The method of claim 1 wherein the rolling input in a first direction represents zoom-in and the rolling input in a second direction, opposite to the first direction, represents zoom-out.

5. The method of claim 1 further comprising generating an icon image of the trackball on the display that corresponds to whether the trackball is in a rest position or is in a rolling position.

6. The method of claim 5 wherein the rest position corresponds to the zoom being at any one of a minimum zoom level, an intermediate zoom level and a maximum zoom level;

and the method further comprising generating one of three icon images.

7. The method of claim 6 wherein the icon corresponding to the minimum zoom level indicates that only zooming-in is available;

the icon corresponding to the intermediate zoom level indicates that both zooming-in and zooming-out are available; and

the icon corresponding to the maximum zoom level indicates that only zooming-out is available.

8. The method of claim 1 wherein the device includes a telephony or instant messaging application, the method further comprising presenting a notification screen, overlaying the viewfinder, indicating that an incoming communication is being received via the telephony or instant messaging application.

9. The method of claim 8 wherein the notification screen includes an identifier of an originator of the incoming communication;

the identifier including a photograph of the originator.

10. The method of claim 9 wherein the notification screen includes an ignore field and an accept field, and the ignore field is highlighted by default.

11. A portable electronic device comprising:

a processor interconnecting a trackball, a light-sensitive transducer, a display, a persistent storage device and a volatile storage device;

the processor configured to generate a viewfinder on the display;

the viewfinder reproducing an image, received via the light-sensitive transducer, the image having a field of view; and

the processor configured to receive rolling input from the trackball and to enlarge or reduce the field of view of the image on the viewfinder depending on a direction of the rolling input.

12. The device of claim 11 wherein the rolling input in a first direction represents zooming-in and the rolling input in a second direction, opposite to the first direction, represents zooming-out.

13. The device of claim 11 wherein the processor is further configured to generate, in conjunction with the viewfinder, an icon image of the trackball on the display that corresponds to whether the trackball is in a rest position or is in a rolling position.

14. The device according to claim 13 wherein the rest position corresponds to the zoom being at any one of a minimum zoom level, an intermediate zoom level and a maximum zoom level.

15. The device of claim 14 wherein the processor is configured to generate three icons corresponding to the rest position;

a first one of the icons corresponding to the minimum zoom level indicates that only zooming-in is available;

a second one of the icons corresponding to the intermediate zoom level indicates that both zooming-in and zooming-out are available; and

a third one of the icons corresponding to the maximum zoom level indicates that only zooming-out is available.

16. The device of claim 11 wherein the device includes at least one of a telephony application or an instant messaging application;

the processor further configured to generate a notification screen, overlaying the viewfinder, indicating that an incoming communication is being received via the telephony or instant messaging application.

17. The device of claim 16 wherein the notification screen includes an identifier of an originator of the incoming communication;

the identifier including a photograph of the originator.

18. The device of claim 17 wherein the notification screen includes an ignore field and an accept field, and the ignore field is highlighted by default.

19. A computer program product, for a portable electronic device having a camera function, the portable electronic device including a processor, a light-sensitive transducer for receiving a first image and a trackball for use as a user-input device, the computer program product comprising a nontransitory computer storage medium having a computer-readable program code adapted to be executed on said processor to implement a method of controlling the display of the portable electronic device, the method comprising:

setting a default zoom level;

activating a viewfinder by generating a second image on the display that corresponds to the first image;

the second image having a field of view that corresponds to the default zoom level;

receiving rolling input from the trackball;

the input representing an instruction either to zoom-in to or zoom-out from the field of view;

adjusting the zoom level based on whether the instruction indicated zoom-in or zoom-out; and

regenerating the second image, on the viewfinder, with an enlarged or reduced field of view according to the zoom level from the adjusting.
