Device and method for the recognition of glasses for stereoscopic vision and relative method to control the display of a stereoscopic video stream

摘要

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.
