Capsule Endoscopy Display Control Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display apparatuses for capsule endoscopes require cumbersome mouse operations to change playback speed and direction of image sequences, making it difficult to perform desired display operations while observing a series of images.
Innovation Solution
An image display apparatus with a control unit that switches between button operation mode and cursor operation mode based on the cursor's position on the screen, allowing for easier navigation and control of image playback using either button or cursor interactions within a specific area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cursor operation mode is used to change playback speed and direction, then precise control of image display is achieved, but operation complexity increases and ease of use deteriorates
Solution Approach 1:
The display screen is divided into a specific area and other areas. When the cursor is in the specific area, button operation mode is activated which simplifies operations to basic button clicks for playback control. When the cursor moves to other areas, cursor operation mode activates for more precise control. This spatial segmentation resolves the contradiction by providing different operation complexities in different screen regions.
Solution Approach 2:
The operation mode dynamically switches between button operation mode and cursor operation mode based on cursor position. The control unit automatically transitions between modes, providing simplified button operations when needed and precise cursor control when needed, without requiring manual mode switching. This dynamic adaptation resolves the contradiction between ease of operation and control precision.
2Ease of operation
If button operation mode is used throughout, then ease of operation improves, but control precision corresponding to screen position deteriorates
Solution Approach 1:
Different operation modes are applied to different screen regions. The specific area triggers button operation mode for simplified control, while other areas enable cursor operation mode for precise position-based control. This local differentiation resolves the contradiction by providing appropriate operation precision for each screen region while maintaining overall ease of use.
3Measurement precision
If cursor movement to icons is required for playback control, then control precision is maintained, but operation time increases
Solution Approach 1:
The system preliminarily determines the appropriate operation mode based on cursor position before execution. When the cursor is in the specific area, button operation mode is automatically activated in advance, eliminating the need for cursor movement to icons. This preliminary mode selection resolves the contradiction by preparing the optimal control method before the user needs to perform operations, reducing operation time while maintaining precision when needed.

AI summary
Provided is an image display apparatus which includes a display unit that displays a series of images obtained by imaging an inside of a subject in time sequence, and displays a specific area with a predetermined size; and an input unit having an input button group for performing a display operation of the images. The apparatus also includes a control unit that performs a control so that an operation mode is set to a button operation mode for performing the display operation of the images with a button operation of the input unit when a cursor on a display screen is in the specific area, and the operation mode is set to a cursor operation mode for performing the display operation of the images corresponding to at least a position on the display screen and a position of the cursor when the cursor is out of the specific area.
