Endoscopic ROI Highlight Switching for Real-Time and Stored Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical image processing systems lack the ability to adjust highlight displays of regions-of-interest differently between real-time image diagnosis and subsequent image viewing, such as in still images or presentations, potentially causing the region-of-interest to be inconspicuous.
Innovation Solution
A medical image processing apparatus that allows users to change the highlight display settings from a first level to a second level through user input, enabling different visual representations of regions-of-interest in real-time and stored images, with options for altering frame thickness, number of lines, and color of the frame shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the highlight display uses a subtle setting suitable for real-time diagnosis, then the doctor's attention is not distracted during image diagnosis, but the highlight becomes inconspicuous when the image is later viewed for reports or presentations
Solution Approach 1:
The system dynamically changes the highlight display characteristics based on the display mode. When a still image is displayed after real-time diagnosis, the highlight display automatically changes to a more conspicuous form (e.g., changing from a thin line to a thicker frame, or from a subtle color to a more prominent color) to ensure the region-of-interest remains noticeable in reports and presentations.
Solution Approach 2:
The system changes the parameters of the highlight display (such as line thickness, color intensity, or frame style) according to the display context. During real-time diagnosis, a subtle highlight is used to avoid distraction, while in still image display mode, the highlight parameters are adjusted to be more prominent, ensuring the region-of-interest is easily noticeable without requiring manual reconfiguration.
2Loss of information
If the highlight display is made more conspicuous for stored images, then the region-of-interest is easily noticeable, but it may become too obtrusive during real-time diagnosis
Solution Approach 1:
The highlight display characteristics are dynamically adjusted based on the operational mode. During real-time diagnosis, the system uses a subtle highlight setting that provides sufficient indication without being distracting. When transitioning to still image display mode (for reports or presentations), the system automatically switches to a more conspicuous highlight setting, ensuring the region-of-interest remains prominent without causing distraction during active diagnosis.
Solution Approach 2:
The system modifies the highlight display parameters (such as line thickness, color saturation, or frame prominence) according to the display context. In real-time diagnosis mode, parameters are set to provide subtle indication, while in still image mode, parameters are increased to enhance visibility, thereby avoiding diagnostic distraction while ensuring noticeability when needed.
3Ease of operation
If a single highlight setting is used for both real-time display and stored images, then the system is simple to operate, but it cannot adapt to different display purposes
Solution Approach 1:
The system automatically adapts the highlight display characteristics based on the display mode without requiring manual configuration. During real-time diagnosis, the subtle highlight setting is applied, and when a still image is displayed (indicating the image has been stored and is being viewed for reports or presentations), the system automatically switches to a more conspicuous highlight setting. This dynamic adaptation maintains ease of operation while providing versatility for different display purposes.
Solution Approach 2:
The highlight display system is designed to serve multiple functions through a single unified mechanism. The same highlight display infrastructure is used for both real-time diagnosis and still image presentation, but the characteristics automatically adapt to suit each purpose. This multi-functionality eliminates the need for separate settings or configurations while ensuring appropriate highlight visibility for each display context.

AI summary
A processor device includes an image signal acquisition unit, an image processing unit, a display control unit, an image storage control unit, and a user input reception unit. The image processing unit detects a region-of-interest, superimposes and displays a highlight display, and performs a setting change from a first highlight level setting value to a second highlight level setting value for changing a shape of the highlight display to be different. The second highlight level setting value is stored together with an endoscopic image.
