Endoscope Touch Panel Cursor Control with Dual Variation Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscope apparatuses require complex operations to accurately change the display range and position of endoscope images, particularly when using stereo measurement functions, which can be cumbersome and time-consuming, especially when trying to specify measurement points or adjust image sizes.
Innovation Solution
An endoscope image display apparatus with a touch panel interface that allows for distinct operation modes in two image display regions, enabling different amounts of variation for cursor movement and zoom operations based on user input, facilitating faster and more precise control over image positioning and sizing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional operation devices such as joysticks are used to specify measurement points or adjust display range, then measurement precision and display accuracy can be achieved, but the ease of operation deteriorates due to complicated and time-consuming operations
Solution Approach 1:
The patent replaces the mechanical joystick operation system with a touch panel interface that utilizes the display screen itself as the input device. Users can directly touch and drag positions on the displayed image to specify measurement points or adjust display ranges, eliminating the need for separate mechanical control devices and simplifying the operation process while maintaining precision.
Solution Approach 2:
The patent introduces an intermediary processing mechanism that converts touch panel input gestures into precise measurement point specifications or display range adjustments. The system detects touch positions and drag distances, then calculates corresponding coordinate changes or zoom levels, serving as a mediator between simple user touch actions and precise measurement functions.
2Manufacturing precision
If conventional joysticks are used to accurately change display range, then display precision can be maintained, but productivity deteriorates due to the number of operations required
Solution Approach 1:
The patent replaces mechanical joystick-based display range adjustment with direct touch panel interaction. Users can pinch-to-zoom or drag gestures directly on the displayed image to rapidly adjust display ranges with high precision, eliminating multiple joystick manipulation steps and significantly improving operational efficiency.
Solution Approach 2:
The patent implements preliminary positioning functionality where the system automatically positions measurement points or display ranges based on preliminary user selections or default configurations. This preliminary action reduces the number of subsequent adjustment operations needed, improving productivity while maintaining precision through fine-tuning capabilities.
3Ease of operation
If touch panel interface is implemented for easier operation, then ease of operation improves, but device complexity increases due to integration of touch sensing and display control functions
Solution Approach 1:
The patent merges the display function and input function into a single integrated touch panel system. The display screen simultaneously serves as both the output medium for showing endoscope images and the input device for specifying measurement points or adjusting display ranges, eliminating the need for separate control devices and reducing overall system complexity despite the enhanced functionality.
Solution Approach 2:
The touch panel is designed with multi-functionality, serving as both display output and various input methods (touch, drag, pinch-to-zoom gestures) within a single interface component. This universal design consolidates multiple functions into one device, improving ease of operation while managing complexity through standardized multi-purpose hardware.

AI summary
An endoscope apparatus includes a display section with a touch panel having a left image display region and a right image display region and a control section. The control section is configured to perform display control so as to change, upon receiving a drag operation instruction while the left image display region selected, a position of a cursor displayed in the left image display region and the right image display region by an amount of variation da, and change, upon receiving a drag operation instruction while the right image display region selected, the position of the cursor displayed in the left image display region and right image display region by an amount of variation db.
