Shutter glasses, display apparatus including the same, and control method thereof

Shutter glasses for viewing a three-dimensional (3D) image on a display apparatus, the shutter glasses comprising:

• a shutter unit comprising a left shutter and a right shutter;
• a sync signal processor which processes a sync signal for alternately opening and shutting the left shutter and the right shutter, the sync signal comprising error-correction information for correcting an error of the sync signal that causes malfunction of the shutter unit;
• and
• a controller which controls the sync signal processor to generate a corrected sync signal corrected according to the error-correction information when receiving the sync signal from the display apparatus, and which controls the shutter unit to selectively open and shut the left shutter and the right shutter in response to the corrected sync signal.

A method of controlling shutter glasses for viewing a three-dimensional (3D) image, the method comprising:

• receiving a sync signal comprising error-correction information for correcting an error that causes malfunction of the shutter glasses;
• generating a corrected sync signal corrected based on the error-correction information;
• and
• selectively opening and shutting a left shutter and a right shutter of the shutter glasses in response to the corrected sync signal.

A sync signal generating apparatus comprising:

• a communication unit which communicates with shutter glasses;
• and
• a sync signal generator which generates a sync signal to open and close shutters of the shutter glasses according to a three-dimensional (3D) video signal, the generated sync signal comprising error-correction information for correcting an error that causes malfunction of the shutter glasses,
• wherein the sync signal generator transmits, to the shutter glasses, the generated sync signal comprising the error-correction information through the communication unit.
