This invention describes a method for changing a picture orientation of a
picture taken by an image sensor of an electronic device, e.g., for
taking horizontal and vertical pictures, preferably having identical
picture size and a picture aspect ratio, without changing an orientation
of an electronic device containing said image sensor. The electronic
device can be a camera, a portable communication device, a mobile
electronic device or a mobile phone. When using a cross-shaped image
sensor, both horizontal and vertical pictures can be taken without
rotating the camera. The image sensor can have other shapes for
accomplishing the same goal, e.g., square shape. A user interface needs
just one button for choosing the orientation and the chosen orientation
will be also seen on the display (viewfinder) of the electronic device.
The viewfinder can have non-picture areas used for displaying image and
photography information.
