Solution Overview

Problem

Conventional 3D projection systems using a single screen limit audience immersion and require complex image correction processes due to the need for individual image alignment on multiple projection surfaces, which can lead to errors and inconvenience, such as the need for polarized glasses that may cause discomfort.

Innovation Solution

A guide image generation device and method that stores parameters representing the structure of a multi-projection theater in a database, allowing for the creation of optimized guide images for integrated image correction across multiple projection surfaces, enabling batch processing and standardized management of projection systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multi-projection system is used to provide 3D images and immersion, then audience immersion and involvement are improved, but the image correction process becomes very complex and error-prone

Engineering Contradiction:
Improveaudience immersionVSAvoidimage correction process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by storing theater structure parameters (projection surface positions, sizes, arrangement configurations) in a database and using these parameters to automatically generate guide images. This transforms the complex manual image correction process into an automated parameter-driven process, reducing complexity while maintaining the multi-projection system's immersive capabilities

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements preliminary action by pre-storing theater structure parameters in a database before the image correction process. The guide images are generated in advance based on these stored parameters, allowing the correction process to proceed systematically without real-time complexity, thus resolving the contradiction between immersion and correction complexity

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If individual image correction is performed on each projection surface, then image alignment accuracy is improved, but the correction process time and error probability increase

Engineering Contradiction:
Improveimage alignment accuracyVSAvoidcorrection process time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges the correction process by generating a single integrated guide image that encompasses all projection surfaces simultaneously. This unified guide image allows for coordinated correction across multiple surfaces, maintaining alignment accuracy while reducing the overall correction time and minimizing error accumulation that would occur with sequential individual corrections

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If theater structure changes occur, then adaptability to new configurations is improved, but the image correction process must be redone increasing complexity

Engineering Contradiction:
Improvetheater structure adaptabilityVSAvoidrepeated correction process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamics by creating a parameter-based system where theater structure parameters can be dynamically updated in the database to reflect configuration changes. The guide image generation process automatically adapts to new parameters, allowing the system to respond flexibly to theater reconfigurations without requiring complex manual recalibration procedures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses copying by storing theater structure parameters in a database that can be replicated and reused. When theater configurations change, updated parameters are stored and automatically used to generate new guide images, eliminating the need to recreate correction procedures from scratch and reducing the complexity of adapting to new configurations

Inventive Principle:
Principle #26Copying
