Camera Flash Accessory Setting Priority Across Unit Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup systems face user inconvenience when switching between different external flash apparatuses, as they require manual resetting of settings due to inconsistent set values across different flash units.
Innovation Solution
An accessory apparatus and image pickup apparatus system that allows for communication between the camera body and accessory units to determine and prioritize set values based on user preferences, storing and managing multiple set values to maintain consistent settings across flash unit changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image pickup apparatus clears the set value when an attachment change of the external flash apparatus is detected, then the system ensures that settings are specific to each flash unit, but user convenience deteriorates when the user wishes to use the same set value across different flash apparatuses
Solution Approach 1:
The system dynamically switches between two operational modes: automatically clearing set values when attachment changes are detected (for reliability), and preserving set values across different flash apparatuses when user preference is set (for convenience). This dynamic adaptability resolves the contradiction by allowing the system to optimize for either reliability or ease of operation based on user needs.
Solution Approach 2:
The invention changes the parameter of set value persistence by introducing a user-selectable mode that determines whether set values are cleared or preserved upon attachment change. This parameter change allows the system to adapt its behavior to balance between ensuring setting accuracy and maintaining user convenience across different usage scenarios.
2Adaptability or versatility
If different external flash apparatuses have different settable functions and set values, then each flash apparatus can be optimized for its specific capabilities, but the user must manually reset settings when switching between apparatuses
Solution Approach 1:
The system performs preliminary action by storing set values in the image pickup apparatus before the user needs to switch flash apparatuses. When a new flash apparatus is attached, the system can automatically transfer or restore the previously stored set values, eliminating the need for manual resetting and saving the user's time while maintaining adaptability to different apparatuses.
Solution Approach 2:
The invention uses copying by transferring set values from one flash apparatus context to another. The image pickup apparatus stores a copy of the set values and applies this copy when a different flash apparatus is attached, allowing the user to maintain consistent settings across multiple apparatuses without manual intervention, thus reducing time loss while preserving apparatus-specific adaptability.
3Ease of operation
If the system stores set values in the image pickup apparatus, then settings can be preserved across flash apparatus changes, but the system complexity increases due to additional memory and control logic
Solution Approach 1:
The image pickup apparatus's existing memory and processing units are made multi-functional by enabling them to store and manage set values in addition to their primary functions. This universality approach allows the system to provide setting continuity across flash apparatus changes without adding dedicated separate components, thereby minimizing the increase in system complexity while achieving ease of operation.

AI summary
An accessory apparatus is attachable to and detachable from an image pickup apparatus. The accessory apparatus includes an accessory processor configured to acquire a first set value for the accessory apparatus stored in the image pickup apparatus through communication with the image pickup apparatus, and an accessory memory storing a second set value for the accessory apparatus. The accessory processor is configured to determine whether to preferentially use the first set value or the second set value as a set value for the accessory apparatus according to a user setting.
