Abstract
This invention relates to the recording and display three-dimensional (3D) images, notably in real-time video capture. This invention focuses on the ability to alter vergence instantaneously through software in order to amend disparities caused by differences between focal length and vergence distance. No mechanical means are necessary for amending both horizontal and vertical disparity. The ability to vary vergence allows selected images to be made to appear behind, level with, or in front of a display screen. While the invention is useful for consumer displays in television and films, the invention may also be used, for example, for visualizing weather, for mapping, for seismic surveys or for aircraft flight control. It is applicable, in real time, throughout the electro-magnetic spectrum particularly in the visible, infra-red and microwave portions.
