Accessory Controller Communication Reset for Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face challenges in quickly recovering from communication errors between the camera body and lens unit, leading to prolonged communication reset processes, which can disrupt image stabilization and affect image quality.
Innovation Solution
The camera system implements an accessory apparatus with an accessory communicator and controller that detects communication errors and initiates a restoration process without waiting for a response from the camera body, allowing the lens unit to perform a communication reset independently, while the camera body allows the accessory apparatus to perform a communication restoration process without responding to error notices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera body controls the communication reset process of the lens unit, then the communication reset can be performed, but it takes a long time to complete the communication reset process
Solution Approach 1:
The lens unit independently performs the communication reset process by transmitting a reset start signal to the camera body and executing the reset without waiting for camera body control. This self-service approach eliminates the time-consuming sequential control mechanism and rapidly restores communication functionality when errors occur.
Solution Approach 2:
Instead of the camera body controlling the lens unit's communication reset as in conventional systems, the invention inverts the control relationship by enabling the lens unit to autonomously initiate and execute the reset process, with the camera body merely receiving notification and permitting the operation.
2Reliability
If the lens unit transmits an error notice to the camera body, then the error can be notified, but the camera body cannot quickly return to communication-enabled state
Solution Approach 1:
The lens unit proactively transmits an error notice to the camera body before the communication is fully interrupted, enabling the camera body to prepare for the upcoming communication reset and minimize disruption to the overall communication process.
3Reliability
If the camera body waits for a response to the error notice, then communication control can be maintained, but the communication restoration process is delayed
Solution Approach 1:
The lens unit independently executes the communication reset process without waiting for the camera body's response to the error notice. This autonomous operation eliminates the response waiting time and rapidly restores communication functionality.
Solution Approach 2:
The lens unit skips the conventional wait-for-response step and directly proceeds with the communication reset process after transmitting the error notice, rushing through the restoration process to minimize communication suspension time.

AI summary
The present invention provides as an aspect thereof an accessory apparatus detachably attachable to an image-capturing apparatus. The accessory apparatus includes an accessory communicator configured to enable communication with the image-capturing apparatus, and an accessory controller configured to perform the communication with the image-capturing apparatus through the accessory communicator. The accessory controller is configured, in response to detecting an error in the communication, to transmit an error notice that notifies the image-capturing apparatus of the error, and to perform a communication restoration process for restoring the communication, without waiting for a response to the error notice from the image-capturing apparatus.
