Projection Device Screen Identification via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices struggle to clearly identify multiple screens when displaying multiple images simultaneously, making it difficult to determine the order and origin of the images, especially with a large number of screens.
Innovation Solution
A projection device and method that includes input, storage, and projection control means to add identification information to image signals, allowing multiple screens to be projected as one image with indications for each screen, enabling clear identification of the respective screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple screens are projected simultaneously to display multiple images, then the information display capability is improved, but the screen identification clarity deteriorates
Solution Approach 1:
The patent divides the projection display into multiple distinct screen regions (first screen, second screen, etc.), each representing a separate image source. This segmentation allows multiple images to be displayed simultaneously while maintaining clear visual separation between them, resolving the contradiction by organizing the quantity of displayed content into identifiable segments.
Solution Approach 2:
The patent applies different local qualities to different screen regions by displaying identification information (such as screen numbers or source identifiers) in specific locations associated with each screen. This allows each screen region to have distinctive characteristics that enable clear identification, even when multiple screens are projected simultaneously.
2Productivity
If multiple screens are arranged in one screen to increase display capacity, then the productivity is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent segments the single projection screen into multiple distinct display areas, each corresponding to a specific image source or function. This segmentation maintains high display capacity while improving ease of operation by making each screen region visually distinct and identifiable through dedicated identification markers.
Solution Approach 2:
The patent introduces identification information as an intermediary element between the multiple screens and the viewer. This intermediary provides contextual cues that help users quickly understand which screen corresponds to which image source, thereby improving ease of operation without reducing display capacity.
Data Source
AI summary
A projection device comprises an input section for inputting an image signal, a storage section for storing the image signal input by the input section after adding identification information thereto, a projection section for forming and projecting an optical image corresponding to the image signal, and a projection control section for using an image signal currently input by the input section and the image signal already stored in the storage section to cause the projection section to project, as one image, a plurality of screens together with indications based on the identification information for the respective screens.
