Apparatus and method for correcting depth map for three-dimensional image

Abstract

Disclosed are an apparatus and method for correcting a depth map for a three-dimensional image, which are capable of accurately correcting an initially-generated depth map in accordance with characteristics of an image, thereby achieving an enhancement in picture quality of a three-dimensional image. The disclosed apparatus includes an original depth map generating unit for generating an original depth map for frame image data externally supplied to the original depth map generating unit, and a depth map correcting unit for analyzing the externally-supplied frame image data, calculating an image pattern of the frame image data and per-pixel brightness values of the frame image data, based on results of the analysis, and correcting the original depth map output from the original depth map generating unit, based on the calculated image pattern and the calculated brightness values, thereby generating a corrected depth map.
