Abstract:
The present invention relates to stereoscopic display systems. It describes a method tor the recognition of stereoscopic glasses, wherein two images of an environment in front of a screen are acquired from the same point of view. A differential image is then calculated by subtracting one of the two images from the other one, and the presence of two lenses is detected within the differential image. The invention also relates to a method for controlling the display of stereoscopic images by using the method for the recognition of glasses. Also described are the devices allowing said methods to be implemented.
Abstract:
A wireless command device adapted to cooperate with a command regenerator device is described, said command device comprising: - a command transmitter adapted to issue a command signal receivable by the command regenerator device; - an activation transmitter adapted to send an activation signal for activating the command regenerator device; - energy collecting means arranged to collect energy from electromagnetic waves picked up by a main antenna connected thereto; - processing means configured for determining if said command device has sufficient energy to issue the command signal; said activation signal being adapted to activate energy irradiating means included in the command regenerator device, said energy irradiating means being adapted to irradiate electromagnetic waves with at least a first power value Pc capable of powering the command device for the purpose of issuing the command signal.
Abstract:
The invention relates to a system (1) and a method for displaying a stereoscopic video stream. The system comprises a display device (3) for displaying the video stream in a stereoscopic or monoscopic mode. The system also comprises stereoscopic glasses (2) for watching in stereoscopic mode the video stream displayed by the display device. The stereoscopic glasses (2) comprise a sensor (20) which detects the presence of a head when the glasses (2) are being worn, and a transmitter (21) which transmits to the display device (3) a piece of information indicating that the glasses are being worn. The display device (3) receives the piece of information transmitted by the stereoscopic glasses (2) and displays the stereoscopic video stream in monoscopic or stereoscopic mode as a function of the piece of information received.
