Abstract
An apparatus and method for controlling the depth of a three-dimensional image. The apparatus includes: a disparity measuring unit which measures the disparity between a left eye image and a right eye image; a physical distance calculating unit which calculates the physical distance between the left eye image and the right eye image based on the measured disparity and the physical characteristics of a display; and a depth controlling unit which controls the depth depending on the calculated physical distance. It is possible to adaptively control the disparity to control the depth when a user uses a stereoscopic three-dimensional display having a different screen size than a display used in a manufacturing environment.
