Abstract
A viewing system for viewing video displays having the appearance of a three dimensional image.
Claims49
A 3D viewing system, comprising:
- a projector for transmitting an image for a left eye of a viewer, an image for a right eye of the viewer, and a synchronization signal;
- and
- 3D glasses including left and right viewing shutters to permit a user of the 3D glasses to view either the left eye image or the right image, comprising:
- a signal sensor for sensing the transmitted synchronization signal;
- a signal processor operably coupled to the signal sensor for modifying at least one of the amplitude, the shape, the dynamic range, and the contrast of the sensed synchronization signal;
- and
- a controller operably coupled to the signal processor for processing the modified synchronization signal to control the operation of the left and right viewing shutters.
A method of controlling the operation of a system for viewing 3D images by a user wearing 3D glasses having left and right viewing shutters, comprising:
- transmitting an image for a left eye of a viewer;
- transmitting an image for a right eye of the viewer;
- transmitting a synchronization signal;
- sensing the synchronization signal;
- processing the synchronization signal by modifying at least one of the amplitude, the shape, the dynamic range, and the contrast of the sensed synchronization signal;
- and
- controlling the operation of the left and right shutters using the modified synchronization signal.
A system for controlling the operation of a system for viewing 3D images by a user wearing 3D glasses having left and right viewing shutters, comprising:
- means for transmitting an image for a left eye of a viewer;
- means for transmitting an image for a right eye of the viewer;
- means for transmitting a synchronization signal;
- means for sensing a synchronization signal;
- means for processing the synchronization signal by modifying at least one of the amplitude, the shape, the dynamic range, and the contrast of the sensed synchronization signal;
- and
- means for controlling the operation of the left and right shutters using the modified synchronization signal.
A method for displaying multiple images on a projection display system, the method comprising:
- displaying a first image from a first image stream on a display plane during a first display period;
- displaying a second image from a second image stream on the display plane during a second display period, wherein the first image and the second image are displayed at least partially on a same area of the display plane, and wherein the first display period and the second display period do not overlap;
- displaying a synchronization signal on the display plane during a third display period;
- and processing the synchronization signal by modifying at least one of the amplitude, the shape, the dynamic range, and the contrast of the sensed synchronization signal.
A method for synchronizing a viewing device to a display system, the method comprising:
- detecting a synchronizing signal displayed on a display plane of the display system;
- receiving the synchronizing signal;
- and
- performing an action in response to the synchronizing signal;
- wherein receiving the synchronizing signal comprises processing the synchronization signal by modifying at least one of the amplitude, the shape, the dynamic range, and the contrast of the sensed synchronization signal.
