Endoscope Image Processing Device for Rotatable Display Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large screen display devices in endoscope systems obstruct pathways due to their width, requiring cumbersome adjustments and reducing convenience in medical settings.
Innovation Solution
An image processing device that adjusts the orientation of the video signal to match the setting state of the display screen, allowing it to be configured either horizontally or vertically, thereby reducing the width and improving pathway accessibility without the need for frequent adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large screen display device is used to improve observation image quality, then the display quality is improved, but the width of the display device increases and obstructs the pathway
Solution Approach 1:
The display device is made rotatable about a vertical axis, allowing it to dynamically change its orientation between horizontal and vertical settings. This enables the display to adapt its width along the pathway direction based on spatial requirements, resolving the contradiction between maintaining large screen display quality and reducing pathway obstruction.
Solution Approach 2:
The orientation parameter of the display device is changed from fixed to variable, allowing rotation between different angular positions. By changing the orientation parameter, the effective width of the display along the pathway can be adjusted without changing the physical size of the screen, thus maintaining display quality while reducing pathway obstruction.
2Ease of operation
If the display device is moved to secure the pathway, then the pathway accessibility is improved, but the display device needs to be moved back to the original setting place, requiring cumbersome work
Solution Approach 1:
The rotatable display device allows for dynamic reconfiguration of the operating space without requiring physical relocation of the entire display unit. The pathway can be secured by rotating the display to a vertical orientation, and the display can be returned to its original horizontal setting by simply rotating it back, eliminating the need for cumbersome moving operations.
Solution Approach 2:
The display device itself provides the adjustment mechanism through its rotatable design. The device can be reoriented to accommodate pathway requirements and then restored to its optimal viewing position without requiring external intervention or complex setup procedures, making the adjustment process self-contained and simple.
3Length of moving object
If the display device is rotated to change orientation, then the pathway obstruction is reduced, but the image orientation may become misaligned
Solution Approach 1:
The image processing device is designed to handle multiple display orientations universally. It can automatically adapt the image orientation to match either the horizontal or vertical display configuration, ensuring that the image remains properly aligned regardless of which orientation the display is set to, thus resolving the contradiction between reducing pathway obstruction and maintaining image alignment.
Solution Approach 2:
The image processing device changes the orientation parameter of the displayed image based on the display device's current orientation. When the display is rotated to a vertical position to reduce pathway obstruction, the image processing device相应地 rotates the image to maintain proper alignment, ensuring that the image remains correctly oriented in both horizontal and vertical display configurations.

AI summary
An image processing device for an endoscope outputs a video signal to an image display part that displays an observation image based on the video signal. The image display part is configured such that a first side of a display screen that displays the observation image is shorter than a second side intersecting with the first side, and is configured to be set in both a first setting state in which the first side is along a vertical direction and a second setting state in which the second side is along the vertical direction. The image processing device includes: a setting state recognition part configured to recognize the setting state; and a video signal generation part configured to generate the video signal such that the subject image in the observation image has an orientation corresponding to the setting state of the image display part.
