Multi-Projector System for High-Density Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projector systems are limited in their ability to display a large amount of information efficiently, as they require reducing image size to accommodate multiple images, which complicates the process of switching between images and projecting them effectively.
Innovation Solution
A projection system comprising multiple projectors that can switch images based on stored data, allowing one projector to project the image of another, thereby increasing the number of images displayed and improving convenience through wireless communication and image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple images are projected on a single screen, then the amount of information displayed increases, but the image size must be reduced which complicates the switching process
Solution Approach 1:
The patent transitions from projecting multiple reduced images on a single screen to using multiple projectors that can project different images in different directions. This spatial dimensionality change allows each projector to maintain full image size while displaying multiple images simultaneously, and enables simple switching by directing images to different projection surfaces rather than switching on a single screen.
2Quantity of substance
If image size is reduced to accommodate multiple images, then more images can be displayed, but the projection quality and information density per image decrease
Solution Approach 1:
The patent divides the single projection system into multiple independent projectors, each capable of projecting full-quality images. This segmentation allows each projector to maintain optimal projection quality for its assigned image while the system as a whole displays multiple images by utilizing different projection surfaces or directions, eliminating the need to reduce image size.
3Quantity of substance
If a single projector displays multiple images, then information quantity increases, but the device complexity increases due to image reduction and management
Solution Approach 1:
The patent makes each projector universal by enabling them to perform multiple functions: each projector can project its own source image independently and can also project images from other projectors. This multi-functionality simplifies the overall system architecture compared to a single projector handling all image processing, as each unit operates autonomously while contributing to the collective display capability.

AI summary
A projection system includes a first projector that projects an image based on image data in a first projection direction, a second projector that projects an image based on image data in a second projection direction, and a storage section that stores the image data representing the image projected by the first projector. The projection system can switch the image projected by the second projector to the image based on the image data stored in the storage section.
