Abstract
An apparatus and method for displaying a three-dimensional image according to the position of a user, in which the distance between a display panel displaying a two-dimensional image and a three-dimensional optical panel converting a two-dimensional image into a three-dimensional image is controlled in accordance with the position of the user to provide an optimized three-dimensional image. The apparatus includes a three-dimensional optical device converting a displayed two-dimensional image into a three-dimensional image, a position measurement module measuring the position of the user who converges on the three-dimensional image, a crosstalk calculator calculating the level of crosstalk that can occur in the position of the user, and a driver adjusting a position of the three-dimensional optical device if the level of crosstalk exceeds a predetermined threshold value.
