Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting image resolution on patient monitoring devices are inconvenient and non-intuitive, requiring multiple steps and operations that reduce usability.
Innovation Solution
A method and apparatus using a touch screen to detect user touch operations, generate touch information, identify user motion, and adjust image resolution based on predetermined conditions, allowing direct and intuitive resolution changes on the image display interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a special interface is opened to adjust resolutions by choosing Display Interval button, then resolution adjustment function is achieved, but operating steps increase and usability decreases
Solution Approach 1:
The patent combines the resolution adjustment function with the existing trend chart display interface by allowing direct touch operations on the trend chart area. The touch screen detects user touches directly on the displayed chart, and the system adjusts resolution without requiring users to navigate to a separate settings interface, thereby merging two previously separate functions into one integrated interaction.
Solution Approach 2:
The patent extracts the resolution adjustment capability from the complex settings menu and implements it as a direct touch gesture feature. By detecting touch motions directly on the trend chart display area, the system separates the adjustment function from the settings interface, allowing users to modify resolution through simple touch gestures rather than navigating through multiple menu levels.
2Measurement precision
If multiple operating steps are required to adjust resolution using knob or mouse, then resolution control precision is achieved, but operation time increases
Solution Approach 1:
The patent implements preliminary action by detecting the user's touch motion trajectory and calculating the desired resolution adjustment before the user completes the gesture. The system continuously monitors touch movements and prepares resolution changes in real-time, so that when the user lifts their finger, the adjustment is already computed and ready to be applied, eliminating the need for additional confirmation steps.
Solution Approach 2:
The patent skips intermediate steps in the resolution adjustment process by directly translating touch motion into resolution changes. Instead of requiring users to navigate through menu options, select from predefined intervals, and confirm changes, the system rushes through the adjustment by interpreting touch gestures directly as resolution commands, significantly reducing the time required while maintaining precision through motion analysis.

AI summary
Disclosed are a method and apparatus for adjusting resolution of medical image. When adjusting resolution, a touch screen is used for display and input. A the method may include: detecting a touch operation inputted by a user through the touch screen under an interface state for displaying a digital image and generating touch information; identifying motion of the user's touch operation in accordance with the touch information and generating motion information; judging whether the detected touch motion meets a predetermined condition for adjusting resolution; if yes, computing an adjusted resolution based on the motion information and a predetermined computing method and displaying data with the adjusted resolution on a region desired to be adjusted on the interface; and when the detected touch motion fails to meet the predetermined condition for adjusting resolution, maintaining the display on the interface with an original resolution on the interface.
