Image Pickup Accessory Firmware Updates with Managed Power Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firmware update methods for image pickup apparatus and accessories are vulnerable to power interruptions, particularly when the update is initiated externally, leading to potential operational failures.
Innovation Solution
An image pickup apparatus and accessory system that includes a communication unit, power supplying unit, and processor to manage power supply and software updates, ensuring seamless firmware updates even during power transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware update is instructed from outside (external power supply scenario), then the firmware can be updated remotely, but the power to the accessory may be unexpectedly turned off causing update failure
Solution Approach 1:
The image pickup apparatus detects the start of firmware update before the actual update begins, and proactively switches the power supply from the accessory's first power supply to the apparatus's second power supply. This preliminary power supply switching ensures that power interruption is prevented before it can occur during the update process.
Solution Approach 2:
The image pickup apparatus acts as an intermediary power source between the accessory's original power supply and the firmware update process. When update is detected, the apparatus supplies power from its own second power supply to the accessory, mediating the power delivery to ensure continuous power during the vulnerable update period.
2Adaptability or versatility
If the accessory uses its own power supply, then the accessory maintains operational independence, but power interruption during update cannot be prevented
Solution Approach 1:
The power supply configuration dynamically changes based on the update state. During normal operation, the accessory uses its own first power supply maintaining independence. When update is detected, the system dynamically switches to the second power supply from the image pickup apparatus, adapting the power configuration to the current operational context.

AI summary
An image pickup apparatus is attachable to and detachable from an accessory. The image pickup apparatus includes a communication unit configured to communicate with the accessory, a power supplying unit configured to supply power to the accessory, a memory configured to store instructions, and a processor configured to execute the instructions and instruct the accessory to update software stored in the accessory via the communication unit. The accessory is operable with power supplied from a first power supply provided in the accessory. The image pickup apparatus is operable with power supplied from a second power supply provided in the image pickup apparatus. The processor supplies the power from the second power supply to the accessory in updating the software.
