Display Device Orientation Zoom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operational display devices with rotational functionality face challenges in maintaining visibility and ease of use when rotated, as existing solutions often require cumbersome operations to zoom-in on specific areas, leading to poor visibility and difficulty in focusing on intended portions, especially when transitioning between horizontal and vertical orientations.
Innovation Solution
An operational display device equipped with a detection system for orientation changes, which automatically adjusts the display by rotating and zooming-in on specific image portions when the device is rotated, ensuring maximum visibility without requiring additional zoom-in operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is rotated to change orientation, then the display can be viewed in different directions, but the image becomes zoomed-out and visibility of specific portions deteriorates
Solution Approach 1:
The system performs preliminary detection of orientation changes through the detection unit, and automatically executes zoom-in operations on specific portions before the user needs to view the image. When rotation is detected, the control unit proactively identifies the region of interest and applies zoom-in transformation, so that when the user views the display in the new orientation, the image is already optimized for visibility.
2Ease of operation
If automatic rotational display is implemented, then the display image remains erected when viewed from the user, but the user must perform additional zoom-in operations to focus on specific areas
Solution Approach 1:
The system makes itself serve the user's needs by automatically detecting orientation changes and executing appropriate display adjustments without requiring user commands. The detection unit monitors orientation, and the control unit autonomously determines which specific portion to zoom in on, eliminating the need for users to manually initiate zoom operations while maintaining the erected display function.
Solution Approach 2:
The system implements a feedback loop where the detection unit continuously monitors the orientation of the display device, and the control unit adjusts the display based on this feedback. When rotation is detected, the system receives feedback about the new orientation and automatically responds by selecting and zooming in on the appropriate region, creating a closed-loop system that adapts to user needs without additional input.
3Measurement precision
If zoom-in display is performed on the entire image, then visibility improves, but the user cannot focus on specific intended portions
Solution Approach 1:
Instead of uniformly zooming in the entire image, the system applies local quality by selectively zooming in on specific portions identified as regions of interest. The control unit determines which specific portion should be magnified based on the orientation and display context, applying zoom-in transformation only to that local region while maintaining appropriate viewing of the overall image structure.
Data Source
AI summary
An operational display device includes a display portion for displaying an image based on image data including a specific portion, a detection portion for detecting an orientation in which the display portion is held, and a display control unit for controlling a manner of display on the display portion. The display control unit causes an image of the specific portion to be displayed as being zoomed-in and rotated in accordance with an orientation of holding of the display portion when the orientation in which the display portion is held is changed from a first orientation to a second orientation.
