Abstract

A method for converting an image in an image conversion apparatus is provided. The method includes receiving a stereo image, down-scaling the stereo image, performing stereo-matching by applying adaptive weight to the down-scaled stereo images, generating a depth map according to the stereo-matching, up-scaling the depth map by referring to an input image of original resolution, and generating a plurality of multi-view images by performing depth-image-based rendering with respect to the up-scaled depth map and the input image of original resolution. Accordingly, a plurality of multi-view images may be obtained with ease.

Description

technical field [0001] Methods and devices consistent with the exemplary embodiments relate to an image conversion device and a display device and method using the image conversion device, and more particularly, to an image conversion device that converts a stereoscopic image into a multi-viewpoint image and uses the same A display device and method for converting a device. Background technique [0002] With the development of electronic technology, various home appliances with multiple functions have been produced. One of those home appliances is a display device such as a television. [0003] Recently, 3D display devices that allow users to view three-dimensional (3D) images have also become popular. 3D display devices may be classified into glasses-type systems or non-glasses-type systems according to whether users need glasses to view 3D images. [0004] One example of a glasses-type system is a shutter glasses method that allows a person to experience a stereoscopic ...
