Abstract
A method and apparatus for adjusting disparity in a 3D image and a 3D imaging device thereof are provided. The apparatus includes a disparity estimator which estimates disparity in an input 3D image and determines a disparity histogram pixel-wise; a disparity adjustor which analyzes energy of a parallax range of the disparity histogram and determines a disparity adjustment amount; and a 3D image reproducer which reproduces the 3D image based on the disparity adjustment amount. Accordingly, the disparity adjustment amount is determined by analyzing disparity energy of the disparity histogram, so a viewer may feel visual comfort and an optimal stereoscopic effect may be provided.
