Instantaneous 180-degree 3D recording and playback systems
First Claim
1. A method for binocular recording and binocular playback, comprising:
- a recording device having two cameras whose imaging process uses three fields of view—
central binocular, left monocular, and right monocular—
to form an instantaneous 180°
horizontal field of view, and two playback devices having two image displays using three fields of view—
central binocular, left monocular, and right monocular—
to form an instantaneous 180°
horizontal field of view, where a left camera corresponds to the left monocular field of view and the left view of the central binocular field of view and a right camera corresponds to the right monocular field of view and the right view of the central binocular field of view, wherein two 3D projection directions of the two cameras (or playback devices’
) intersect in 3D to give a perception of depth.

Abstract
The term instantaneous in this invention means that the roughly 180° horizontal visual field of view that a human senses in real time. The major novelty of the instantaneous 180° (i180°) 3D technology includes (a) a combination of multiple binocular and monocular fields of view for image acquisition, (b) a combination of binocular and monocular fields of view in content playback, (c) a multi-resolution scheme for sensing, processing, transmission, and playback, (d) a realization of physical consistency of the line of sight with minimal distortion of all projection lines between imaging and display, and (e) a method for two-way compatibility for systems with conventional binocular 3D and monocular 2D systems. In addition to applications in consumer electronics, the invention has potential applications in professional business, such as film industry, theaters, museums, advertisements, surgery, rehabilitation, and assistance to the handicapped and elderly.
