Viewfinder State Transitions in Image Pickup Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image pickup apparatuses face challenges in improving operability while downsizing, particularly in the transition states of the viewfinder, requiring manual power management and detection operations.
Innovation Solution
An image pickup apparatus with a viewfinder that automatically transitions between housed and usage states, featuring a detection section controlled by a control unit to manage power and detection operations based on state changes, allowing seamless power management and enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the viewfinder is made foldable or capable of being housed in the main body for downsizing, then the portability and compactness are improved, but the operability deteriorates due to requiring separate manual power management and detection operations
Solution Approach 1:
The patent combines the power management function and detection section control with the viewfinder's state transition mechanism. When the viewfinder transitions between housed and extended states, the power section and detection section are automatically controlled accordingly, merging multiple operations into a single unified action that improves ease of operation while maintaining compactness
Solution Approach 2:
The system enables self-service operation where the viewfinder's state transition automatically triggers power management and detection section control without requiring separate manual user input. The apparatus serves itself by detecting its own state changes and autonomously managing power and detection functions based on whether the viewfinder is housed or extended
2Measurement precision
If manual power management and detection operations are required for viewfinder state transitions, then the control precision is improved, but the productivity deteriorates due to increased operational steps
Solution Approach 1:
The patent implements preliminary action by pre-configuring the power section and detection section to be automatically controlled based on viewfinder state transitions. The system is prepared in advance to detect state changes and automatically manage power and detection functions, eliminating the need for separate manual operations and thereby improving shooting efficiency while maintaining detection accuracy
