METHOD AND APPARATUS FOR DISPLAYING IMAGES

The present description discloses a method and apparatus for displaying images. An image display method according to one embodiment of the present invention comprises the following steps: generating, from an inputted source, 3D image data to be outputted; taking, as an input, first information on whether or not there are a plurality of viewers, and, in the event there are a plurality of viewers, on the number of viewers, and second information on the viewing mode of each viewer based on the first information; generating individual synchronization information for the generated 3D image data in response to the viewing mode of each viewer in accordance with the inputted first information and second information; and outputting the generated 3D image data via a screen, and transmitting the generated synchronization information to the 3D eyeglasses of each viewer. In addition, an image display method according to another embodiment of the present invention comprises the following steps: generating, from an inputted source, 3D image data to be outputted and first synchronization information; outputting the generated 3D image data via a screen, and transmitting the generated first synchronization information to each viewer; generating second synchronization information on the basis of the generated first synchronization information in accordance with a received viewing mode switch request; and transmitting the generated second synchronization information to the 3D glasses of the corresponding viewer.
