Camera-based orientation fix from portrait to landscape
First Claim
1. A method for use in a portable electronic device having a camera and a display screen for which the display mode is switchable between a portrait mode and a landscape mode in response to an inertial sensor, the method comprising:
- capturing a first image of a feature of a user of the device with the camera;
determining that the display mode should be switched based on an output of the inertial sensor indicating movement of the device after capturing the first image;
capturing a second image of the feature of the user of the device with the camera in response to the determining that the display mode should be switched based on the output of the inertial sensor indicating the movement of the device; and
disabling the switching of the display mode determined based on the output of the inertia sensor if the second imaged feature changes orientation with respect to the device in comparison to the first imaged feature by less than a threshold amount.

Abstract
A portable electronic device includes a camera and a display switchable between a portrait mode and a landscape mode in response to an inertial sensor. When it is determined that the display mode should be switched in response to movement of the device, a feature of a user of the device, such as the user'"'"'s face, is imaged with the camera. If the imaged feature changes orientation with respect to the display by less than a threshold amount, then the switch in display mode is disabled and the display remains in its current mode. Other embodiments are also described and claimed.

15. A portable electronic device comprising:
-
an inertial sensor; a display whose display mode is switchable between a portrait mode and a landscape mode; a processor for determining that the display mode should be switched in response to movement of the device sensed by the inertial sensor; and a camera for creating images of a feature of a user of the device; wherein the processor is configured to control the inertial sensor, display and camera to; capture a first image of a feature of a user of the device with the camera; determine that the display mode should be switched based on an output of the inertial sensor indicating movement of the device after capturing the first image; capture a second image of the feature of the user of the device with the camera in response to the determining that the display mode should be switched based on the output of the inertial sensor indicating the movement of the device; and disable the switching of the display mode determined based on the output of the inertia sensor if the second imaged feature changes orientation with respect to the device in comparison to the first imaged feature by less than a threshold amount. - View Dependent Claims (16, 17, 18)

19. A non-transitory computer readable medium having program instructions, which when executed by a processor perform a method, the method comprising:
-
capturing a first image of a feature of a user of a portable electronic device using a camera of the device; determining that a display mode of the device should be switched between a portrait mode and a landscape mode based on an output of an inertial sensor of the device indicating movement of the device after capturing the first image; capturing a second image of the user feature with the camera in response to the determining that the display mode should be switched based on the output of the inertial sensor indicating the movement of the device; and disabling the switching of the display mode determined based on the output of the inertia sensor if the second imaged feature changes orientation with respect to the device in comparison to the first imaged feature by less than a threshold amount. - View Dependent Claims (20, 21, 22, 23)
