Solution Overview
Problem
Users face cumbersome operations when setting and releasing the privacy mode on camera-equipped information processing devices, lacking user-friendliness.
Innovation Solution
An information processing apparatus with an imaging unit, determination unit, and mode selection unit that acquires an image, determines the brightness output value, and selects the privacy mode when the value meets a predetermined condition, allowing intuitive and easy mode switching by detecting when the camera is covered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the privacy mode function is provided to mask camera images for privacy protection, then privacy protection capability is improved, but user operation complexity increases requiring burdensome operations to set and release the mode
Solution Approach 1:
The system automatically detects whether the camera is being covered by monitoring image brightness levels and autonomously switches between privacy mode and normal mode without requiring user intervention. The camera system serves itself by using its own imaging capability to detect coverage state and trigger appropriate mode changes
Solution Approach 2:
The patent replaces manual mechanical operations (physically navigating menus and pressing buttons to toggle privacy mode) with an automated optical detection system that monitors image brightness and automatically triggers mode switching based on detected coverage conditions
2Measurement precision
If manual setting operations are required to activate privacy mode, then system control precision is improved, but user convenience deteriorates requiring troublesome operations
Solution Approach 1:
The system continuously monitors image brightness as feedback from the camera sensor and uses this information to automatically determine when the camera is covered. This feedback loop enables the system to autonomously switch modes based on real-time detection of coverage state, eliminating the need for manual user input while maintaining accurate mode control
3Ease of operation
If the system automatically detects camera coverage through brightness analysis, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent makes the camera system multi-functional by enabling it to perform both its primary function of capturing images and a secondary function of detecting its own coverage state through brightness analysis. The same imaging unit serves dual purposes, eliminating the need for separate detection hardware and reducing overall system complexity
