Projector Non-Volatile Storage for Portable Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display systems lack portability and suffer from delayed image display due to the need for a personal computer (PC) to be present for image projection, as they require continuous data transmission from the PC to the projector.
Innovation Solution
An image display system with a non-volatile storage unit in the projector allows for independent storage and display of processed image information, eliminating the need for real-time data transmission from the PC and enabling portable operation without delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is stored in the PC and transmitted to the projector for display, then the system can display stored images, but the system loses portability as the PC must be moved along with the projector
Solution Approach 1:
The invention extracts the image storage function from the PC and places it directly in the projector. The projector is equipped with a storage device that can store image data independently, allowing the projector to display images without requiring the PC to be present. This separation enables the projector to be moved independently while maintaining full display functionality.
Solution Approach 2:
The system is segmented into independent functional components: the PC handles image capture and initial processing, while the projector handles storage and display. The storage device in the projector is a separate component that can be filled via USB connection, allowing independent operation and enhancing portability.
2Speed
If image data is transmitted from the PC to the projector for real-time display, then the display can be updated continuously, but delays occur depending on the volume of image data
Solution Approach 1:
The invention implements preliminary action by pre-storing image data in the projector's storage device. Once the storage device is filled via USB connection, the projector can immediately display images without requiring continuous data transmission from the PC. This eliminates transmission delays and allows instant image display.
Solution Approach 2:
The system creates a copy of image data in the projector's storage device. The storage device contains a duplicate of the image data from the PC, allowing the projector to display images independently without real-time connection to the PC, thus eliminating transmission delays.
3Ease of operation
If the projector displays images from stored data without PC connection, then portability is enhanced and delays are reduced, but the PC is no longer necessary for image storage
Solution Approach 1:
The projector is designed to be self-sufficient with its own storage device. The storage device can be filled via USB connection and then allows the projector to operate independently without requiring the PC for image storage or retrieval. The projector serves itself by storing and displaying images from its own storage capacity.

AI summary
An image display system includes an information processing apparatus and an image display apparatus. The information processing apparatus includes: a processing unit that acquires image information and executes image processing for the image information; a processed image information acquisition command unit that gives an acquisition command to an image display apparatus; and a transmitting unit that transmits the processed image information and the acquisition command to the image display apparatus. The image display apparatus includes: an image receiving unit that receives the processed image information; a non-volatile image information storing unit that stores the processed image information; an acquiring unit that acquires at least either the processed image information received by the receiving unit or the processed image information stored in the storing unit; and a control unit that commands an apparatus display unit to display an image corresponding to the processed image information acquired by the acquiring unit.
