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 multi-directional input device operable to receive input in at least three directions;
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 input from the multi-directional input device in a substantially cardinal direction;
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;
regenerating the second image, on the viewfinder, with an enlarged or reduced field of view according to the zoom level from the adjusting;
receiving an input from the multi-directional input device corresponding to the multi-directional input device being depressed; and
in response to the multi-directional input device being depressed, capturing at least a portion of the first image, the portion corresponding to the second image within the viewfinder according to the zoom level.

11. A portable electronic device comprising:
-
a processor interconnecting a multi-directional input device operable to receive input in at least three directions, 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; the processor configured to receive input from the multi-directional input device in a substantially cardinal direction and to enlarge or reduce the field of view of the image on the viewfinder depending on a direction of the input; the processor further configured to receive input from the multi-directional input device corresponding to the multi-directional input device being depressed; and
in response to the multi-directional input device being depressed, to capture at least a portion of the first image, the portion corresponding to the second image within the viewfinder according to the zoom level. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

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 multi-directional input device operable to receive input in at least three directions, 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 input from the multi-directional input device in a substantially cardinal direction;
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; regenerating the second image, on the viewfinder, with an enlarged or reduced field of view according to the zoom level from the adjusting; receiving an input from the multi-directional input device corresponding to the multi-directional input device being depressed; and in response to the multi-directional input device being depressed, capturing at least a portion of the first image, the portion corresponding to the second image within the viewfinder according to the zoom level.
