Rotatable Web Camera Display Orientation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices with web cameras face the challenge of adjusting display images without incurring additional costs, as the prior method relies on physical locks (tenons) which are costly and inefficient.
Innovation Solution
An electrical device with a rotatable web camera and an image sensor that generates brightness signals to determine the display mode based on the camera's orientation, allowing the processing unit to adjust the display image accordingly without additional hardware costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical lock (tenon) is used to determine display image adjustment, then the display image orientation can be controlled, but the manufacturing cost increases
Solution Approach 1:
The patent replaces the mechanical tenon lock system with an optical detection system using the web camera's image sensor. The processing unit analyzes ambient illumination characteristics captured by the camera to automatically determine whether the camera is oriented toward or away from the user, and accordingly adjusts the display image orientation without any mechanical components.
Solution Approach 2:
The web camera serves dual functions: both capturing images for communication and detecting ambient illumination for automatic display orientation adjustment. The system uses the camera's inherent image sensor to detect environmental light conditions, eliminating the need for separate sensors or mechanical indicators, and enabling self-adjustment based on captured image data.
2Ease of manufacture
If no additional hardware is used for adjustment, then manufacturing cost is reduced, but the ability to detect camera orientation becomes insufficient
Solution Approach 1:
The patent makes the web camera's image sensor perform multiple functions: capturing images for communication and detecting ambient illumination for orientation determination. By analyzing the brightness and illumination characteristics of the captured image data, the processing unit can infer the camera's orientation relative to the user without requiring dedicated orientation sensors or additional hardware components.
