Embodiment Construction

[0071] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0072] FIG. 6 is a block diagram of a multi-view moving image encoding device according to an exemplary embodiment of the present invention.

[0073] The multi-view moving image encoding apparatus includes a multi-view image buffer 610 , an estimation unit 620 , a disparity / motion compensator 630 , a residual image encoder 640 and an entropy encoder 650 .

[0074]In FIG. 6, the multi-view moving image encoding apparatus receives multi-view video images obtained from multiple video sources such as camera systems or obtained using different methods. The received multi-view video images are stored in the multi-view image buffer 610 . The multi-view image buffer 610 provides stored multi-view video source data or images to the estimation unit 620 and the residual image encoder 640 .

[0075] The estimation unit 620 includes a disparity estimator ...

Abstract

A method and apparatus are provided for encoding and decoding a multi-view moving picture. A method of estimating a disparity vector to encode a multi-view moving picture includes: estimating disparity vectors for a predetermined number of encoded macroblocks; and calculating disparity vectors of macroblocks adjacent to the encoded macroblocks using the estimated disparity vectors. Therefore, it is possible to quickly perform encoding of a multi-view moving picture and enhance compressibility of the multi-view moving picture.

Description

technical field [0001] Methods and devices consistent with the present invention relate to encoding and decoding of multi-view moving images, more specifically, to a disparity vector estimation method for quickly encoding multi-view moving images and improving the compressibility of multi-view moving images, and It relates to a method and device for encoding and decoding multi-view moving images using the disparity vector estimation method. Background technique [0002] Authenticity is an important factor in achieving high-quality information and telecommunications services. Authenticity can be achieved using three-dimensional (3D) image-based video communications. 3D image system has many potential applications in education, entertainment, medical operation, video conferencing and so on. In order to provide the viewer with more vivid and accurate information of the remote scene, three or more cameras are arranged at slightly different viewpoints to produce a multi-view se...
