Display Apparatus Attitude Detection for Image Orientation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for portable devices struggle to ensure optimal viewing of both horizontally and vertically oriented images, particularly during rapid playback of moving images, as they often require frequent attitude changes of the device, leading to incomplete viewing of images due to unintentional orientation changes.
Innovation Solution
A display apparatus equipped with an attitude detection system that pauses playback if the device attitude does not align with the image orientation, prompting the user to adjust the device for proper viewing and resuming playback only when aligned, thereby preventing mid-playback orientation changes and ensuring optimal image viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device automatically rotates images based on detected attitude changes during playback, then image orientation adaptability is improved, but playback continuity is deteriorated due to frequent interruptions when users unintentionally change device orientation
Solution Approach 1:
The system dynamically adjusts its response to attitude changes based on playback state. During playback, attitude detection is suspended to maintain continuity, while orientation alignment is enforced before playback starts. This dynamic behavior resolution allows the system to adapt to different operational phases, improving playback continuity without permanently sacrificing orientation adaptability.
2Manufacturing precision
If the device pauses playback to enforce orientation alignment, then image viewing quality is improved, but playback efficiency is deteriorated due to frequent pauses
Solution Approach 1:
The system performs orientation alignment as a preliminary action before playback starts, rather than continuously during playback. By checking and enforcing attitude alignment in advance and suspending attitude detection during playback, the system ensures high viewing quality without frequent interruptions, thus maintaining playback efficiency.
3Measurement precision
If attitude detection is continuously active during playback, then orientation accuracy is improved, but device complexity is deteriorated due to additional control logic
Solution Approach 1:
The system uses periodic attitude detection with different frequencies based on playback state. Attitude detection is active before playback to ensure proper orientation, then suspended during playback to reduce processing load and complexity. After playback, detection resumes to prepare for the next orientation adjustment. This periodic approach maintains orientation accuracy while simplifying control logic.

AI summary
A display apparatus including a display unit, adapted to playback a sequence of images, comprises: a detection configured to detect an attitude of the display apparatus or the display unit; a control unit configured to control the display unit to pause playback of the sequence of images, if the detected attitude of the display apparatus is not substantially aligned with the orientation of an image to be displayed.
