Active 3D to Passive 3D Conversion via Color Tinting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and cumbersome nature of active 3D glasses, along with the need for compatible glasses for multiple viewers, limits the ability to watch active 3D content with large groups due to the requirement for each viewer to have their own pair of active 3D glasses.
Innovation Solution
A method and system that convert active 3D frames into passive 3D images by tinting each perspective image with different colors, allowing passive 3D glasses to display a 3D viewing experience without the need for active glasses, using a tuner device to transmit tinted images to an end-user display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active 3D glasses are used for each viewer, then 3D viewing quality is maintained, but cost and device complexity increase significantly
Solution Approach 1:
The patent creates a copy of the active 3D signal in passive 3D format. The tuner device receives the active 3D signal and generates a corresponding passive 3D signal that can be viewed with passive glasses, effectively copying the 3D content in a different format that doesn't require expensive active glasses for each viewer
Solution Approach 2:
The patent changes the fundamental parameter of the 3D signal from active to passive format. By converting the signaling method and image processing approach, the system allows multiple viewers to use passive glasses simultaneously without requiring multiple pairs of active glasses
2Reliability
If active 3D glasses are used for each viewer, then individual 3D viewing experience is ensured, but cost increases for large groups
Solution Approach 1:
The patent makes the passive 3D glasses universal for all viewers simultaneously. Instead of requiring individual active glasses for each person, a single passive 3D signal can be viewed by multiple people using passive glasses, making the viewing solution universal and scalable to any group size
Solution Approach 2:
The system creates a passive 3D copy of the original active 3D signal, allowing unlimited distribution to multiple viewers without requiring additional active glasses for each person
3Reliability
If active 3D signal is transmitted, then 3D quality is maintained, but compatibility with passive 3D display devices is lost
Solution Approach 1:
The tuner device acts as an intermediary between the active 3D signal source and the passive 3D display device. It receives the active 3D signal, processes it through image scaling and tinting, and outputs a passive 3D signal that is compatible with passive display devices while maintaining 3D quality
Solution Approach 2:
The patent changes the signal parameters from active to passive format through image scaling and tinting operations. This parameter transformation maintains the essential 3D quality while making the signal compatible with passive display devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables multiple viewers to watch 3D content using passive 3D glasses, reducing the need for multiple active 3D glasses and providing a cost-effective solution for group viewing by converting active 3D signals into passive 3D format, allowing for simultaneous 3D viewing without the need for active glasses.
Implementation Method 1

AI summary
Various arrangements for using an active 3D signal to create passive 3D images are presented. An active 3D frame may be received. The active 3D frame may comprise a first perspective image and a second perspective image. The first perspective image may be representative of a different perspective than the second perspective image. The first perspective image may be tinted with a first color. The second perspective image may be tinted with a second color different from the first color. The first perspective image tinted with the first color may be displayed. The second perspective image tinted with the second color may be displayed.
