Imaging Accessory Wake-Up Control via Segmented Operation Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems with auto power-off functions do not efficiently manage the restart of operations based on specific user interactions, leading to suboptimal power saving and operational flexibility.
Innovation Solution
The implementation of a communication system between imaging apparatuses and accessories, allowing for designation of specific operation members to wake up the system from a sleep state, ensuring only necessary components are activated upon user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the imaging system returns to normal operation state upon any operation member operation in sleep state, then operational responsiveness is improved, but power saving performance deteriorates
Solution Approach 1:
The operation members are segmented into two categories: wake-up operation members that can activate the system from sleep state, and non-wake-up operation members that cannot. This segmentation allows selective responsiveness based on operation type, enabling the system to remain unresponsive to certain operations during sleep state while maintaining responsiveness to designated wake-up operations, thus achieving both power saving and operational responsiveness.
2Use of energy by moving object
If the imaging system designates specific operation members for wake-up function, then power saving performance is improved, but device complexity increases
Solution Approach 1:
The camera controller designates specific operation members as wake-up operation members before the system enters sleep state. This preliminary designation establishes which operations can trigger system wake-up, allowing the accessory controller to check operation member operations during sleep state and selectively communicate with the camera controller only when wake-up operations are detected, thereby achieving power saving without requiring complex real-time decision-making mechanisms.
Solution Approach 2:
The accessory controller serves as an intermediary between the operation members and the camera controller during sleep state. It monitors operations of wake-up operation members and communicates with the camera controller only when relevant operations are detected, eliminating the need for the camera controller to continuously monitor all operation members, thus reducing system complexity while maintaining power saving performance.
3Adaptability or versatility
If all operation members are monitored during sleep state, then operational flexibility is improved, but power consumption increases
Solution Approach 1:
Operation members are segmented into wake-up operation members and non-wake-up operation members. During sleep state, only wake-up operation members are monitored for operations that can trigger system wake-up, while non-wake-up operation members are not monitored. This selective monitoring maintains operational flexibility for critical functions while significantly reducing power consumption compared to monitoring all operation members.
Solution Approach 2:
Instead of monitoring all operation members during sleep state (excessive action), the system monitors only the subset of wake-up operation members that are necessary for system activation (partial action). This partial monitoring approach provides sufficient operational flexibility for wake-up functions while avoiding the excessive power consumption that would result from monitoring all operation members.

AI summary
An imaging apparatus to which an accessory apparatus including a plurality of operation members is detachably attached includes a camera communicator configured to provide a communication path with the accessory apparatus, and a camera controller configured to communicate with the accessory apparatus via the camera communicator, and to transfer to a sleep state with the accessory apparatus when none of the accessory apparatus and the imaging apparatus are operated in a normal operation state. The camera controller designates a specific operation member among a plurality of operation members for the accessory apparatus. The camera controller in the sleep state returns to the normal operation state when receiving a communication from the accessory apparatus corresponding to an operation of the specific operation member.
