Abstract: Provided is a steroscopic video encoding and/or decoding apparatus that supports multi-display modes, the encoding/decoding method thereof, and computer-readable recording medium for recording a program that implements the encoding/decoding method. The encoding apparatus of this research incorporates: a field separating means for separating right and left-eye input images into an odd field of the left-eye image (LO), even field of the left-eye image (LE), odd-numbered field (RO) of the right-eye image, and even-numbered field (RE) of the right-eye image; an encoding means for encoding the fields separated in the field separating means by performing motion and disparity compensation; and a multiplexing means for multiplexing the essential fields among the fields received from the encoding means, based on the user display information.

Abstract: Provided are intelligent water ring scan apparatus and method thereof, image encoding/decoding apparatus using the water ring scanning and method thereof, and a computer-readable recording medium for recording a program that implements the methods. The apparatus or method of this research selectively improves the image quality of a particular image part that needs to be encoded with priority by transmitting the image data of the particular image part suitably for a human visual system so as to provide a visually improved image. The encoding apparatus of this research differentiates the amount of image data depending on the significance of a certain image part to process the image in various qualities suitably for the human visual system. The methods of this research can be applied to an image encoding/decoding process.
