Method and apparatus for generating a stereoscopic image
First Claim
1. A method for generating a stereoscopic image of a scene having a first and a second object, the first object having a first predetermined depth in the scene and the second object having a second predetermined depth in the scene, the method comprising:
- capturing a left and right image of the first object using a first camera separation, wherein the first camera separation is based on a first perceived depth of the first object in a region of interest of the stereoscopic image of the scene, and wherein a ratio of the first perceived depth to the first predetermined depth is set at a desired viewing ratio;
capturing a left and right image of the second object using a second camera separation, wherein the second camera separation is based on a second perceived depth of the second object in a second region of the stereoscopic image of the scene;
generating a composite left image from the left image of the first object and the left image of the second object by overlaying the left image of the first object on top of the left image of the second object;
generating a composite right image from the right image of the first object and the right image of the second object by overlaying the right image of the first object on top of the right image of the second object; and
providing the composite left image and composite right image.

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 idea 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.

10. A method for generating a stereoscopic image of a scene having a first, a second, and a third object, the first object having a first predetermined depth in the scene, the second object having a second predetermined depth in the scene, and the third object having a third predetermined depth in the scene, the method comprising:
-
capturing a left and right image of the first object using a first camera separation, wherein the first camera separation is based on a first perceived depth of the first object in a region of interest of the stereoscopic image of the scene, and wherein a ratio of the first perceived depth to the first predetermined depth is set at a desired viewing ratio; capturing a left and right image of the second object using a second camera separation, wherein the second camera separation is based on a second perceived depth of the second object in a second region of the stereoscopic image of the scene; capturing a left and right image of the third object using a third camera separation, wherein the third camera separation is based on a third perceived depth of the third object in a third region of the stereoscopic image of the scene; generating a composite left image from the left image of the first object, the left image of the second object, and the left image of the third object by overlaying the left image of the first object on top of the left image of the second object on top of the left image of the third object; generating a composite right image from the right image of the first object, the right image of the second object, and the right image of the third object by overlaying the right image of the first object on top of the right image of the second object on top of the right image of the third object; and providing the composite left image and composite right image. - View Dependent Claims (11, 12)
