Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peppers ghost filming and display systems suffer from poor image quality and difficulty in transmitting high-quality displays over limited bandwidth, especially in live communication transmissions.
Innovation Solution
The system employs semi-transparent screens to project virtual images that appear as if they are part of the backdrop, using advanced lighting and camera techniques to enhance 3D effects, and incorporates AR technology for augmented reality displays, with optimized image acquisition and projection methods to improve clarity and realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional filming and display methods are used for peppers ghost images, then the system complexity is reduced, but the image quality and clarity are insufficient to produce lifelike images
Solution Approach 1:
The system divides the image acquisition process into multiple captured images at different positions around the subject, with each image corresponding to a specific viewing angle. This segmentation allows high-quality images to be captured from multiple perspectives, which are then synthesized to create lifelike peppers ghost images, resolving the contradiction between image quality and system complexity.
Solution Approach 2:
The patent introduces an intermediary processing system that captures multiple images from different positions and synthesizes them into the final peppers ghost display. This intermediary mechanism enables high image quality by combining information from multiple sources, while the overall system remains manageable through modular architecture.
2Manufacturing precision
If high quality peppers ghost displays are transmitted over limited bandwidth, then the image clarity is improved, but the transmission capability over network or cable is insufficient for live communication
Solution Approach 1:
The system segments the video transmission into multiple captured images at different positions, which can be processed and transmitted efficiently. By dividing the image data into manageable segments from different viewing angles, the system can optimize for both clarity and transmission efficiency over limited bandwidth channels.
Solution Approach 2:
The patent creates multiple copies of the subject from different positions and angles, then synthesizes these copies to create the final peppers ghost image. This copying approach allows the system to transmit compressed representations of the subject from various perspectives, maintaining image clarity while reducing the data load for transmission over network or cable.
3Manufacturing precision
If multiple captured images at different positions are synthesized to create lifelike peppers ghost images, then the image realism is improved, but the processing time and complexity increase
Solution Approach 1:
The system captures multiple images at different positions around the subject in advance, with each image corresponding to a specific viewing angle. By performing this preliminary capture action before the actual peppers ghost display is needed, the system can reduce real-time processing requirements and create lifelike images more efficiently.

Data Source
AI summary
A system and method for filming and displaying a 3D image is provided, including acquisition of one or more video images at one or more capture locations of one or more subjects, the images being recorded as a data film for storage and playback, or transmission over a network, to a watching audience. The video images at the display venue are projected onto or through semi-transparent screens arranged to appear in front of a backdrop to a stage. The images may be displayed alongside or on the same stage as live performing talent, the projection perceived by the viewing audience as a virtual image. The semi-transparent screen is invisible to the watching audience or the cameras during the performance. The video image viewed by an online audience is perceived as bearing a close likeness to subject(s), providing a real presence of a virtual subject performing on a stage.
