Abstract
A multi-view display device, including a controller that is operable to receive from a positioning device, position information representing positions of a left eye and a right eye of a viewer relative to the multi-view display. The viewer is able to activate a channel selection mode in which the multiview display simultaneously projects different stereoscopic channels on the side of his last position before starting the new mode, so he can see other channels by changing his head position. The viewer selects then a desired channel by which it ends the channel selection mode and switches the display to a mode where only one channel is stereoscopically displayed at a time.
Claims27
A multi-view display controller comprising:
- a processor;
- and
- a memory, wherein said processor is operable to:
- receive video data of at least a first multi-view video channel and a second multi-view video channel;
- receive, from a positioning device, position information representing positions of a left eye and a right eye of a viewer relative to a multi-view display;
- generate, upon reception of an activation signal and based on said position information, view information defining, for at least a first pixel area of said multi-view display, i) a first view of said first multi-view video channel with a view angle projecting said first view of said first multi-view video channel onto said left eye of said viewer, ii) a second view of said first multi-view video channel with a view angle projecting said second view of said first multi-view video channel onto said right eye of said viewer, iii) a first view of said second multi-view video channel with a view angle projecting said first view of said second multi-view video channel onto a point in a first direction relative to said left eye of said viewer, and iv) a second view of said second multi-view video channel with a view angle projecting said second view of said second multi-view video channel onto a point in said first direction relative to said right eye of said viewer;
- and
- output video data of said first multi-view video channel and said second multi-view video channel together with said view information to said multi-view display for simultaneous display of said first multi-view video channel and said second multi-view video channel.

A computer program comprising program code which when executed by a processor causes said processor to:
- receive video data of at least a first multi-view video channel and a second multi-view video channel;
- receive, from a positioning device, position information representing positions of a left eye and a right eye of a viewer relative to a multi-view display;
- generate, upon-on reception of an activation signal and based on said position information, view information defining, for at least a first pixel area of said multi-view display, i) a first view of said first multi-view video channel with a view angle projecting said first view of said first multi-view video channel onto said left eye of said viewer, ii) a second view of said first multi-view video channel with a view angle projecting said second view of said first multi-view video channel onto said right eye of said viewer, iii) a first view of said second multi-view video channel with a view angle projecting said first view of said second multi-view video channel onto a point in a first direction relative to said left eye of said viewer, and iv) a second view of said second multi-view video channel with a view angle projecting said second view of said second multi-view video channel onto a point in said first direction relative to said right eye of said viewer;
- and
- output video data of said first multi-view video channel and said second multi-view video channel together with said view information to said multi-view display for simultaneous display of said first multi-view video channel and said second multi-view video channel.

A multi-view display control method comprising:
- receiving video data of at least a first multi-view video channel and a second multi-view video channel;
- receiving, from a positioning device, position information representing positions of a left eye and a right eye of a viewer relative to a multi-view display;
- generating, upon reception of an activation signal and based on said position information, view information defining, for at least a first pixel area of said multi-view display, i) a first view of said first multi-view video channel with a view angle projecting said first view of said first multi-view video channel onto said left eye of said viewer, ii) a second view of said first multi-view video channel with a view angle projecting said second view of said first multi-view video channel onto said right eye of said viewer, iii) a first view of said second multi-view video channel with a view angle projecting said first view of said second multi-view video channel onto a point in a first direction relative to said left eye of said viewer, and iv) a second view of said second multi-view video channel with a view angle projecting said second view of said second multi-view video channel onto a point in said first direction relative to said right eye of said viewer;
- and
- outputting video data of said first multi-view video channel and said second multi-view video channel together with said view information to said multi-view display for simultaneous display of said first multi-view video channel and said second multi-view video channel.
