Image Sensor Display Orientation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display orientation control systems often inaccurately adjust based on physical changes, leading to incorrect orientations due to the disconnect between display orientation and physical orientation of devices.
Innovation Solution
A display system that uses a sensor, such as a camera or image sensor, to detect reference images like body parts or objects, allowing a processor to control the display orientation based on these images, thereby aligning the display with the intended user without physical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display orientation is controlled by detecting physical changes in device orientation, then the display can automatically adjust to different physical positions, but the display orientation may become incorrect when physical orientation does not reflect intended viewing direction
Solution Approach 1:
The patent replaces the mechanical sensor-based orientation detection system with an image-based detection system. Instead of relying on physical sensors to detect device orientation changes, the system uses an image sensor (camera) to capture images and detect reference objects or reference lines in the visual field, thereby determining the correct display orientation through image processing rather than mechanical sensing.
Solution Approach 2:
The patent introduces an intermediary reference object or reference line that serves as a mediator between the display system and the user's intended viewing direction. The image sensor detects these reference elements in the captured image, and the processor uses them to infer the correct display orientation, establishing an indirect but more reliable connection between physical position and display orientation.
2Ease of operation
If display orientation changes based on physical movement detection, then the system can respond to user positioning, but accidental misalignment occurs when physical movement does not indicate intentional orientation change
Solution Approach 1:
The patent implements a feedback mechanism where the image sensor continuously monitors the visual field for reference objects or lines. The processor analyzes the detected reference elements and determines whether the detected orientation change corresponds to an intentional user action based on the presence and position of these references, providing feedback-based validation before changing display orientation.
Solution Approach 2:
The system replaces mechanical movement detection with optical field detection. Instead of sensing physical acceleration or position changes that cannot distinguish intentional from accidental movements, the system uses an image sensor to detect reference objects in the visual field, which only appear when the user intentionally positions them in view.
3Measurement precision
If the system uses image-based orientation detection with reference objects, then display orientation accuracy improves, but the device complexity increases due to additional sensors and processing
Solution Approach 1:
The patent makes the image sensor multi-functional by using it for both display orientation detection and other device functions such as capturing photos or videos. The same hardware component serves multiple purposes, reducing the need for dedicated orientation-detection hardware and thereby minimizing the increase in device complexity.
Solution Approach 2:
The processor is designed to handle multiple tasks including image processing for orientation detection, photo/video processing, and general device control. By making the processor multi-functional and capable of handling various image processing tasks, the system avoids the need for separate dedicated processing units, thereby reducing overall device complexity.
