2D-plus-Depth or also called 2D + Z format (not to be confused with 2D plus Delta or 2D-plus-DOT) is a Stereoscopic Video Coding format that is used for 3D displays, such as Philips WOWvx. Philips discontinued work on the WOWvx line in 2009, citing "current market developments".〔(Philips Decides to Shut Down 3D Operation, March 27, 2009 )〕 Currently, this Philips technology is used by Dimenco company, led by former key 3D engineers and scientists of Philips. They offer autostereoscopic 3D displays which use the 2D-plus-Depth format for 3D video input.〔(Dimenco's 3D Displays & Technology )〕 == Overview == The 2D-plus-Depth format is described in a Philips' white paper〔(Philips 3D Solutions: 3D Interface Specifications White Paper )〕 and articles.〔("Philips 3D Solutions: From Content Creation to Visualization", Third International Symposium on 3D Data Processing, Visualization, and Transmission (3DPVT'06) )〕 Each 2D image frame is supplemented with a greyscale depth map which indicates if a specific pixel in the 2D image needs to be shown in front of the display (white) or behind the screen plane (black). The 256 greyscales can build a smooth gradient of depth within the image. Processing within the monitor used this input to render the multiview images. Supported by various companies across the display industry, 2D-plus-Depth has been standardized in MPEG as an extension for 3D filed under ISO/IEC FDIS 23002-3:2007(E).〔(Preview of "ISO/IEC 23002-3. Information technology — MPEG video technologies — Part 3: Representation of auxiliary video and supplemental information" )〕 There is also an extension on the 2D-plus-Depth format called the WOWvx Declipse format. It is described in the same Philips' white paper "3D Interface Specifications". In this advanced format, two more planes are added to the original 2D image and its depth map for each frame: the background areas covered by foreground objects and their respective depth map. So, each frame in the Declipse format is described with an image containing four parts, or quadrants. This extension improves potential visual quality by providing data for more correct and precise filling of the uncovered occlusion areas created by shifting foreground objects during the multiview generation process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2D-plus-depth」の詳細全文を読む スポンサード リンク
