Title: APPARATUS AND METHOD FOR DEPTH MAP CORRECTION, AND APPARATUS AND METHOD FOR STEREOSCOPIC IMAGE CONVERSION USING SAME
Abstract:
The present invention relates to an apparatus and method for depth map correction, and to an apparatus and method for stereoscopic image conversion using same. The depth map correction apparatus comprises: a filtering unit for performing noise-filtering or sharp characteristic improvement filtering on an inputted two-dimensional image; a region setup unit for selecting the boundary surface having the largest variation in the characteristics of a pixel from the filtered image and dividing the filtered image into a correction region, a neighboring region and a peripheral region according to the degree of correction in accordance with the selected boundary surface; and a depth value correction unit for performing, on the correction region, interpolation using the filtered image and a pre-generated depth map so as to correct a depth value and generate a corrected depth map by performing depth value correction on the neighboring region and peripheral region.
