Abstract
A display apparatus to display a three-dimensional image (3D) and a method of controlling the same, shutter glasses and a method of controlling the same, and a display system are provided. The shutter glasses include a lens which allows selective light transmission; a signal receiver which receives a first signal; a synchronization signal reconstruction unit which reconstructs a synchronization signal corresponding to a 3D display of the display apparatus through a correlation analysis on the received first signal; and a shutter driver which operates the lens corresponding to the synchronization signal reconstructed by the synchronization signal reconstruction unit.

Shutter glasses configured to communicate with a display apparatus displaying a three-dimensional (3D) image, the shutter glasses comprising:
- a lens which transmits light selectively;
- a signal receiver which receives a first signal;
- a synchronization signal reconstruction unit which performs a correlation analysis on the received first signal to reconstruct a synchronization signal corresponding to a 3D display of the display apparatus;
- and
- a shutter driver which operates the lens based on the synchronization signal reconstructed by the synchronization signal reconstruction unit.
A display apparatus comprising:
- an image receiver which receives an image signal corresponding to a three-dimensional (3D) image;
- an image processor which processes the image signal so that an image is displayed on a display unit;
- a communication unit which is configured to communicate with shutter glasses to operate based on the displayed image;
- and
- a synchronization signal processor which converts a synchronization signal corresponding to a 3D display into a code signal having orthogonality, and transmits the code signal to the communication unit.

- and
- a synchronization signal processor which generates a synchronization signal in which a noise code having a pattern and orthogonality is formed based on a vertical synchronization range of the image signal, and transmits the synchronization signal to the communication unit so that the shutter glasses reconstruct the vertical synchronization range in the synchronization signal range based on the noise code.
Shutter glasses configured to communicate with a display apparatus displaying a three-dimensional (3D) image, the shutter glasses comprising:
