Embodiment Construction

[0040] A 3D video image encoding device, decoding device and method are disclosed. In the following description, numerous specific details are given in order to provide a thorough understanding of embodiments of the invention. It will be apparent, however, to one skilled in the art that these specific details need not be employed to practice the present invention. Conversely, specific details well known to those skilled in the art have been omitted appropriately for clarity.

[0041] In an embodiment of the invention, to the metadata associated with each segment of an event (i.e. with 3D video) data is added indicating the length of the segment, or alternatively or additionally until the next segment boundary (i.e. data for the time when the next segment starts).

[0042]This allows a receiver of 3D video containing metadata to choose whether to use the overall minimum distance disparity for a segment when generating the OSD, depending on when the segment will end and when t...

Abstract

A 3D video image encoding apparatus comprises a segmentation means operable to partition a 3D video image sequence into two or more segments, each comprising one or more 3D video images, image processing means operable to identify a value corresponding to an overall minimum apparent distance to an observer within each segment of the 3D video image sequence, metadata generation means operable to encode the value corresponding to the overall minimum apparent distance for a respective segment within metadata associated with that segment, and the metadata generation means is operable to encode within the metadata an indication of the length of time of the segment, and / or an indication of the time until the next segment. Meanwhile, a 3D video image decoding apparatus comprises a metadata parsing means operable to parse metadata associated with a respective one of a plurality of segments of 3D video, each segment comprising one or more 3D video images, the metadata parsing means being operable to decode from the metadata a value corresponding to an overall minimum apparent distance to an observer for that respective segment, and the metadata parsing means is operable to decode from the metadata an indication of the length of time of that segment and / or an indication of the time until a next segment.

Description

technical field [0001] The present invention relates to a 3D video image coding device, a decoding device, and a method. Background technique [0002] Three-dimensional (3D) or stereoscopic television displays work by presenting stereoscopic video images to the viewer. In practice, this stereoscopic image consists of a pair of images (left and right images) presented to the viewer's left and right eyes, respectively. These left and right images have different viewpoints, therefore corresponding image elements in the left and right images have different absolute positions in the left and right images. [0003] The difference between these absolute positions is known as the disparity between the corresponding image elements. Due to the well-known parallax effect, the viewing distance of the stereoscopic image elements (both left and right versions of the image elements appear to the viewer The presentation of the corresponding eye of ) is a function of this parallax. [000...
