Mobile Terminal Screen Capture via Key Press Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen capturing technologies for mobile terminals are defective and lack maneuverability, failing to meet user needs for capturing and saving screen content effectively.
Innovation Solution
A method and device that detect key events on a mobile terminal to perform full screen or regional screen capturing operations based on a time threshold, allowing users to capture all or selected screen content, enhancing user experience by providing multiple capturing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screen capturing technologies are applied to mobile terminals, then screen content can be captured, but the maneuverability and user experience are poor
Solution Approach 1:
The patent implements dynamic operation modes that adapt to user needs: a first operation mode for quick full-screen capturing and a second operation mode for selective regional capturing. The system dynamically switches between these modes based on user interaction patterns, allowing the capturing mechanism to be both quick (pressing a key once) and flexible (selecting specific regions when needed), thereby resolving the contradiction between maneuverability and capturing effectiveness.
2Adaptability or versatility
If only full screen capturing is implemented, then all screen content can be captured, but user needs for selective capturing are not met
Solution Approach 1:
The patent segments the screen capturing function into two distinct operational modes: full-screen capturing and regional capturing. The regional capturing mode further segments the screen into selectable regions, allowing users to capture only specific areas of interest. This segmentation provides versatility in capturing different portions of the screen while maintaining simple operation through unified key-based activation, resolving the contradiction between adaptability and device complexity.
3Adaptability or versatility
If multiple capturing modes are added to meet diverse user needs, then adaptability improves, but system complexity increases
Solution Approach 1:
The patent implements a universal key-based activation mechanism that serves multiple capturing functions. A single specified key can trigger both full-screen capturing and regional capturing modes depending on the current operation mode. This multi-functionality approach allows the system to provide diverse capturing capabilities without requiring separate controls or complex interfaces for each mode, thereby resolving the contradiction between adaptability and system structure complexity.

AI summary
A method for capturing screen content of a mobile terminal and a device thereof are provided. The method comprises: detecting a DOWN event of a specified key of the mobile terminal and recording the time of occurrence of the DOWN event as a first time stamp; detecting an UP event of the specified key and recording the time of occurrence of the UP event as a second time stamp; and comparing a difference between the second time stamp and the first time stamp with a preset time threshold, performing a full screen capturing or a regional screen capturing on the screen content of the mobile terminal if the difference is less than the preset time threshold, or performing a regional screen capturing or a full screen capturing on the screen content of the mobile terminal if the difference is greater than the preset time threshold.
