Intelligent Display OS-Independent Screen Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen capture methods, such as screen grabs, become ineffective during operating system failures, highlighting the need for mechanisms independent of the operating system to access and store screen data.
Innovation Solution
An intelligent display system with a graphics input interface, image processing module, storage subsystem, and event-driven input device that captures and stores screen data independently of the operating system, allowing for screen data capture and storage without relying on the operating system's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screen capture methods (screen grabs) are used, then screen data can be captured during normal operation, but the capture becomes ineffective during operating system failures
Solution Approach 1:
The patent extracts the screen capture function from the operating system environment and implements it at the hardware level through the intelligent display device. The display captures and stores screen data independently without requiring OS intervention, effectively removing the system dependency that causes failure during OS crashes.
Solution Approach 2:
The intelligent display acts as an intermediary between the computer system and the user/documentation system. It intercepts and stores screen data at the display interface level, serving as a mediator that can operate independently when the OS fails, thereby ensuring continuous capture capability.
2Loss of information
If operating system-dependent capture methods are used, then implementation is simple during normal operation, but data accessibility is lost during system crashes
Solution Approach 1:
The intelligent display performs self-service by autonomously capturing and storing screen data without requiring OS commands or user intervention during critical moments. The display monitors and records its own output, ensuring data preservation even when the system controlling it fails.
Solution Approach 2:
The system performs preliminary action by continuously capturing and storing screen data in real-time before potential failures occur. This proactive approach ensures that data is already saved and accessible even if the system crashes immediately after.

AI summary
In one embodiment, a display device comprises a graphics interface, an image processing system, an input device coupled to the image processing system to receive a screen capture signal and transmit the screen capture signal to the image processing system, and a storage subsystem coupled to the image processing system to store, in response to the screen capture signal, screen capture data generated by the image processing system.
