System and method for peppers ghost filming and display
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 setups to enhance 3D effects, and incorporates LED panels and video processors to optimize image quality and transmission, allowing for immersive telepresence experiences in larger environments.
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 of the projected image deteriorates
Solution Approach 1:
The system divides the filming process into multiple capture locations with separate cameras, allowing each camera to be optimized for specific viewing angles and image quality requirements. This segmentation enables high-quality image acquisition without requiring a single complex all-purpose filming system.
Solution Approach 2:
The patent introduces an intermediary processing system that receives video signals from multiple cameras and processes them to create the final peppers ghost display. This intermediary layer manages the complexity of multiple camera inputs and coordinate transformations, isolating the complexity from the individual camera components.
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 deteriorates
Solution Approach 1:
The video signal is segmented into multiple independent streams from different capture locations. This allows selective transmission of only the essential image data rather than redundant information from all cameras, reducing bandwidth requirements while maintaining image clarity.
Solution Approach 2:
The system changes the parameter of video signal compression and encoding to optimize transmission over limited bandwidth. By adjusting compression ratios and data transmission parameters, the system maintains acceptable image quality while reducing the data load for transmission over network or cable.
3Manufacturing precision
If multiple capture locations are used to improve image quality, then the visual realism is improved, but the device complexity and bandwidth requirements increase
Solution Approach 1:
The multiple cameras at different capture locations are designed with universal functionality to capture the same subject from different angles. Each camera serves multiple purposes: providing different viewing perspectives, enabling depth perception, and creating a comprehensive 3D image database. This multi-functionality justifies the added complexity by delivering superior visual realism.
Solution Approach 2:
The system transitions from 2D single-angle imaging to 3D multi-dimensional imaging by adding capture locations in different spatial dimensions. This dimensional expansion enables the creation of volumetric images that provide depth and realism, with the added complexity managed through standardized capture protocols and processing algorithms.

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.
