What is this patent about?

’922 is related to the field of motion pictures and visual arts, specifically focusing on systems and methods for creating the appearance of continuous movement and three-dimensional depth from two-dimensional images. It addresses the technical challenge of generating fluid, sustained directional motion—referred to as Eternalisms—using a finite number of frames. The background context involves leveraging the human visual system's response to flicker and temporal intervals to produce unique spatial illusions that can be viewed without specialized eyewear, though they may be enhanced by optoelectronic spectacles.

The underlying idea behind ’922 is the repetitive presentation of a sequence consisting of at least two visually similar image frames separated by a dissimilar bridging frame, such as a solid color or a timed unlit-screen pause. By applying specific geometric transformations—such as expanding, shrinking, or reshaping—to the primary image frames before inserting the bridge, the invention creates a cinematic conveyer belt effect. This inventive insight allows a viewer to perceive a gesture or movement, like a door cracking open, as a sustained, evolving action that never actually completes, effectively turning a transient moment into a perpetual visual event.

The claims of ’922 focus on an apparatus comprising a storage and a processor configured to transform a video stream by generating modified image frames and displaying them in a specific sequence with a solid-color bridge frame. The independent claims specifically cover various methods of frame modification, including expanding, shrinking, removing portions, stitching frames together, inserting selected images, or reshaping the original frames. In each claimed embodiment, the processor obtains two frames from a video stream, applies one of these specific modifications to create distinct modified versions, and then displays them in an order interrupted by a generated solid-color bridge frame.

In practice, the invention works by manipulating the spatial relationship of objects between frames to dictate the direction and character of the perceived motion. For example, by slightly shifting the placement of a figure or altering its size across the modified frames, the system can induce a zooming effect or a sliding movement. The solid-color bridge frame acts as a visual reset that prevents the mind from seeing a simple back-and-forth stutter, instead forcing the nervous system to interpret the sequence as a continuous directional flow. This process, termed Eternalizing, allows for the creation of 3D-like volume and movement that remains stable and observable for as long as the loop is maintained.

This approach differs from prior art by moving away from standard film projection techniques that seek to hide flicker. While traditional cinema uses high frame rates and shutters to create the illusion of uninterrupted light, this invention purposely utilizes apparent flicker and specific frame-unit sequencing to achieve time-space aberrations. Unlike standard 3D systems that require dual-lens cameras and polarized glasses, this method generates depth and motion illusions from single-perspective sources. By using the computer to precisely stitch or reshape matching elements into effective screen locations, the invention provides a malleable way to control depth and motion that is impossible in actual life or standard cinematography.

How does this patent fit in bigger picture?

Technical Landscape

In the early 2000s when ’922 was filed, the technical landscape of 3D cinema and home entertainment was characterized by a reliance on static optical solutions at a time when stereoscopic viewing was typically implemented using passive anaglyph or polarized lenses. While digital video processing was advancing, systems commonly relied on fixed-density filters rather than dynamic, electronically controlled optical elements, and hardware constraints made the real-time synchronization of variable-tint materials with high-frequency video streams non-trivial. Engineering practices for depth perception in 2D-to-3D conversion were largely limited to manual post-production or simple Pulfrich-effect spectacles that lacked the ability to adapt to varying motion vectors or ambient lighting conditions.

Prosecution Position

The disclosed invention represents a meaningful technical advancement through the integration of multi-layered optoelectronic materials and automated motion-vector analysis to overcome the inherent latency of variable-tint lenses. By utilizing multiple layers of electronically controlled material, the system achieves an architectural shift that enables faster transition times and extended component cycle life, addressing the technical constraint of slow response speeds in standard electrochromic devices. This configuration enables a dynamic Pulfrich stereoscopic effect that is doubly optimized for both the specific lateral motion within a video frame and the unique operating characteristics of the lens material, allowing for a seamless 3D experience from standard 2D content without requiring specialized dual-lens camera systems or modified broadcast standards.

Claims

The patent contains a total of 12 claims, with claims 1, 3, 5, 7, 9, and 11 serving as the independent claims. These independent claims focus on an apparatus designed to process video streams by obtaining image frames, generating modified versions of those frames through various techniques—such as expanding, shrinking, removing portions, stitching, inserting images, or reshaping—and displaying a solid-colored bridge frame between the modified images. The dependent claims serve to further specify the visual characteristics of the bridge frame, specifically requiring that the solid color used for the transition be black.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Bridge frame
(Claim 1, Claim 3, Claim 5, Claim 7, Claim 9, Claim 11)
The method of the present invention entails repetitive presentation to the viewer of at least two substantially similar image pictures alternating with a third visual interval or bridging picture that is substantially dissimilar to the other substantially similar pictures. Specifically, two or more image pictures are repetitively presented together with a bridging interval (a bridging picture) which is preferably a solid black or other solid-colored picture. In electronic media, the bridge-picture may simply be a timed unlit-screen pause between serial re-appearances of the two or more similar image pictures.A visual interval or bridging picture that is substantially dissimilar to the image frames, specifically a solid-colored picture, used to create an appearance of continuous movement when displayed between image frames.
Modified image frame
(Claim 1, Claim 3, Claim 5, Claim 7, Claim 9, Claim 11)
One or more of the following actions may be performed: generating a modified image frame by removing a portion of an image frame, reshaping a portion of an image frame, and relocating a portion of an image frame. The computer allows for each area to be matched separately and inlaid into the scene according to one's depth-movement intentions for each area. The direction of the off-center, e.g. up, down, right, or left, will determine which direction the series provides the appearance of movement.An image frame derived from a source video frame that has been altered through processes such as expanding, shrinking, removing portions, stitching, inserting images, or reshaping to facilitate the illusion of continuous movement.
Reshaping
(Claim 11)
One or more of the following actions may be performed: reshaping a portion of an image frame, and relocating a portion of an image frame. The processor is adapted to reshape a portion of at least one of the one or more image frames. Varying the size gives the viewer the impression that the man is walking forward or backward, depending on the order in which pictures are arranged.The technical process of altering the form, size, or geometric configuration of an image frame or a portion thereof to create visual differences between sequential frames.
Solid color
(Claim 1, Claim 3, Claim 5, Claim 7, Claim 9, Claim 11)
With A and B frames being similar images, and frame C a contrasting frame (preferably a solid-color picture instead of an image-picture) relative to A,B, frame C acts as essentially a bridge-interval. Any color can be used for the contrasting frame C: for example, blue, white, green; however, black is usually preferred. The contrasting frame can also be chosen from one of the colors in one of the two image pictures.A visual property of a bridge frame where the entire frame consists of a single, uniform color (such as black, white, or blue) to provide contrast against image frames.
Stitching together
(Claim 7)
One or more of the following actions may be performed: generating a collage based on one or more portions of one or more image frames, stitching together one or more portions of one or more image frames, or superimposing a first image frame on a second image frame. The apparatus is adapted to obtain a first image from a first video stream, obtain a second image from a second video stream, and stitch together the first image and the second image to generate a stitched image frame.The process of combining or merging portions of multiple image frames or distinct images into a single composite frame.
