Embodiment Construction

[0088] The method for converting a 2D or "monoplanar" video signal into a 3D or "stereoscopic" video signal according to the invention is referred to as Dynamic Depth Cues (DDC) in the following description, but the invention is not limited to these techniques.

[0089] a) 3D Generation: A technique and procedure for converting 2D images into 3D stereoscopic image pairs and generating 3D converted data.

[0090] b) 3D Scripting: A technique that describes the changes needed in a 2D image to convert it into a 3D stereoscopic image pair. It describes which objects are selected, how to handle them and how to provide 3D storage.

[0091] c) 3D data encoding: a technique for adding information to 2D video images in a certain format. The resulting altered video is compatible with existing video recording, editing, transmission and reception systems.

[0092] d) 3D standard protocol: 3D conversion data is added to 2D video using a defined data format or a standardized protocol. Th...

Abstract

A method of encoding a 2D video signal with conversion data to assist in the conversion of said 2D video signal to left and right eye images for a stereoscopic display, characterised in that said method includes: adding conversion data to said video signal to provide the encoded signal, the data defining the displacement of respective selected points of said video image for converting the video image to a stretched image for a stereoscopic display.

Description

(1) Technical field [0001] The present invention relates generally to stereoscopic image synthesis and in particular to methods of converting two-dimensional (2D) images for further encoding, transmission and decoding of stereoscopic images displayed on two-dimensional (2D) or three-dimensional (3D) stereoscopic display systems. (2) Background technology [0002] Recent advances in high-performance video projection systems, image processing, digital video, and liquid crystal panels have enabled many practical 3D display systems that utilize active and passive polarizers to display autostereoscopic images for single or multiple viewers. [0003] Three-dimensional display systems have moved away from technical curiosities and into display systems for entertainment, business, and scientific applications. There is now an emerging need for displaying 3D media on these devices. There are traditionally two methods of producing such 3D media (ie media containing image information o...
