1. An apparatus for attenuating a stereoscopic sense, the apparatus compring: a graphic processor configured to generate a stereoscopic image to which a disparity is applied; a stereoscopic sense attenuator configured to extract at least one object from the stereoscopic image and perform a stereoscopic sense attenuation for the at least one extracted object according to a position of the at least one extracted object within the stereoscopic image; and a controller configured to control the stereoscopic sense attenuator to output a final stereoscopic image in which an amount of the stereoscopic sense attenuation applied to the at least one extracted object corresponds to the a position of the at least one extracted object within the stereoscopic image.
