APPARATUS, METHOD AND MEDIUM DISPLAYING STEREO IMAGE

An apparatus, method, and medium displaying a stereo image compensates for errors between a left image and a right image to reduce eye fatigue experienced by a user. The apparatus includes a feature-point extractor to extract feature points of graphics objects included in a left image and a right image, of a stereo image, a representative-vector determiner to determine a representative vector among vectors between a predetermined point and the feature points, an error-correction unit to correct at least one of a vertical error and a rotation error between the left image and the right image using a difference between the representative vector determined in the left image and the representative vector determined in the right image, and a display unit to display the left image and the right image for which at least one of the vertical error and the rotation error has been corrected.
