Camera Obstruction Detection via Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of small, flush-mounted camera lenses in mobile devices often leads to obstruction issues when the device is held, as there is no tactile indication of the lens position, resulting in obstructed image acquisition.
Innovation Solution
A device with a processor that detects camera obstructions by analyzing electronic images and automatically controls the camera to acquire second images in burst or video mode, providing notifications when the lens is obscured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the camera lens is made small and flush-mounted to reduce device size, then the mobile device size is reduced, but the lens becomes easily obstructed when the device is held
Solution Approach 1:
The system proactively detects potential lens obstructions by analyzing electronic images for hand or finger presence before the obstruction fully blocks the lens, and provides advance notification to the user to adjust their grip, preventing the obstruction from occurring
Solution Approach 2:
The system continuously monitors images from the camera lens, analyzes them to detect hand or finger presence, and provides real-time feedback through notifications to the user about potential obstructions, enabling the user to adjust their grip accordingly
2Shape
If the camera lens is made small and flush-mounted to improve device integration, then the lens protrusion is reduced, but tactile indication of lens position is lost
Solution Approach 1:
The system uses software-based detection algorithms and notification mechanisms as intermediaries to compensate for the lack of tactile feedback, detecting hand presence through image analysis and alerting users through visual or haptic notifications
3Measurement precision
If the system continuously monitors images to detect obstructions, then obstruction detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system performs image analysis at periodic intervals or triggered by specific events (such as when the camera is active or when certain conditions are detected), rather than continuously analyzing every frame, thereby maintaining detection accuracy while reducing overall energy consumption
