Method and Apparatus for Generating a Stereoscopic Image
First Claim
1. A method of generating a stereoscopic image of a scene, the method comprising:
- —
defining at least one first region of a scene;
forming at least one first image pair, wherein the or each said first image pair comprises a first image of at least a part of a said first region of said scene when viewed from a first location, and a second image of at least a part of said first region when viewed from a second location, spaced from said first location;
carrying out a first mapping process on at least one said first image pair to generate a respective first part of a display image pair;
defining at least one second region of said scene;
forming at least one second image pair, wherein the or each said second image pair comprises a third image of at least a part of a said second region of said scene when viewed from a third location, and a fourth image of at least a part of said second region when viewed from a fourth location, spaced from said third location;
carrying out a second mapping process on at least one said second image pair to generate a respective second part of said display image pair; and
combining the or each first and second part of said display image pairs to form said display image pair, said display image pair being adapted to provide a stereoscopic image of said first and second regions of said scene;
wherein an object having a predetermined depth in a viewing direction in a said first region has a first perceived depth and an object having said predetermined depth in a viewing direction in a said second region has a second perceived depth, different from said first perceived depth, when said stereoscopic image is viewed in stereo.

Abstract
A method of generating a stereoscopic image is disclosed. The method includes defining at least two, three or more regions in a scene representing a region of interest, a near regions and/or a far region. This is followed by forming an image pair for each region, this image pair containing the information relating to objects in or partially in their respective region. The perceived depth within the regions is altered to provide the ideai or best perceived depth within the region of interest and acceptable or more compressed perceived depths in the other regions. The image pairs are then mapped together to form a display image pair for viewing on a display device.
