Camera-based orientation fix from portrait to landscape

摘要

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.

主权项

1. A method for use in a portable electronic device having a camera, an inertial sensor, a processor and a display screen, the method comprising:
detecting, from inertial sensor data, an orientation of the device relative to gravity; capturing, by the camera, an image of a user of the device; determining an orientation of the device relative to the user from the captured image; comparing the detected orientation of the device from the inertial sensor data to the determined orientation of the device relative to the user; and displaying by the display screen a user interface in a selected one of a portrait or landscape display mode based on the comparison.
