SYSTEM AND METHOD FOR PROVIDING 3D IMAGE DATA IN 3D IMAGE SYSTEM

摘要

PURPOSE: A system and a method for providing 3d image data in a 3d image system are provided to convert a depth image into a parallax map to transmit image data by a new transmission method, thereby increasing coding efficiency in transmission and reducing a calculation amount with a memory used in a receiver. CONSTITUTION: The first filtering unit(120) quantizes depth image data using a histogram included in image data received from image photographing devices. The second filtering unit(140) measures discontinuity in the quantized depth image data. The second filtering unit performs smoothing and filtering based on an inclined direction using the discontinuity. An encoding unit(180) encodes reference image data including a generated parallax map and the image data.
