Portable Electronic Apparatus Having More Than one Display Area, and a Method of Controlling a User Interface Thereof
First Claim
1. A portable electronic apparatus having first and second display areas, an orientation sensor configured to provide an orientation sensor output signal indicative of a spatial orientation of said apparatus, and a display controller coupled to said first and second display areas and to said orientation sensor, said display controller being responsive to said orientation sensor output signal to selectively control said first display area and said second display area by maintaining one of said first and second display areas in a first display state, and another of said first and second display areas in a second state, said second display state being a state with less display activity than said first display state;
- determining, from said orientation sensor output signal, a movement of said portable electronic apparatus; and
, in response, causing said one of said first and second display areas to switch from said first display state to said second display state, and said other of said first and second display areas to switch from said second display state to said first display state, the portable electronic apparatus further comprising;
an image processor associated with said display controller, said image processor being configured to investigate a captured image of a surrounding of said other of said first and second display areas for any presence in said captured image of an object in the form of a face of one or more human individuals by executing a face detection algorithm in order to detect the presence of a user of said portable electronic apparatus, and to indicate such presence in an image processor output signal,wherein said display controller is responsive also to said image processor output signal for the selective control of said first display area and said second display area, wherein said display controller is configured, after the determining of a movement of said portable electronic apparatus, to;
verify that said image processor has detected a face in said captured image and thus indicates presence of said user at said other of said first and second display areas; and
perform said causing of said other of said first and second display areas to switch from said second display state to said first display state, only upon an affirmative result from said verification by said image processor.

Abstract
A portable electronic apparatus having first and second display areas is presented. The apparatus has an orientation sensor that provides an orientation sensor output signal indicative of a spatial orientation of the apparatus. The apparatus also has a display controller coupled to the first and second display areas and to the orientation sensor. The display controller is responsive to the orientation sensor output signal to selectively control the first display area and the second display area.

9. A method of controlling a user interface of a portable electronic apparatus having first and second display areas, the method comprising:
-
determining a spatial orientation, or change in spatial orientation, of said apparatus; and selectively controlling said first display area and said second display area in response to the determined spatial orientation, or change in spatial orientation, of said apparatus by; maintaining one of said first and second display areas in a first display state, and another of said first and second display areas in a second state, said second display state being a state with less display activity than said first display state; determining a movement of said apparatus from the determined spatial orientation, or change in spatial orientation, of said apparatus; and
, in response,causing said one of said first and second display areas to switch from said first display state to said second display state, and said other of said first and second display areas to switch from said second display state to said first display state; wherein the method further comprises; receiving a captured image of a surrounding of said other of said first and second display areas; investigating said captured image for any presence therein of an object in the form of a face of one or more human individuals by executing a face detection algorithm in order to detect the presence of a user of said portable electronic apparatus; verifying, after the determining of a movement of said portable electronic apparatus, that a face has been detected in said captured image and thus indicates presence of said user at said other of said first and second display areas; and performing said causing of said other of said first and second display areas to switch from said second display state to said first display state, only upon an affirmative result from said verifying. - View Dependent Claims (10, 11, 12, 13)
wherein said first display area and said second display area are selectively controlled based on a difference between said previous orientation and said current orientation of said apparatus.
