Camera Controller Accessory Communication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging systems face challenges in efficiently managing power consumption by identifying and controlling accessories that do not require communication, leading to unnecessary power usage and potential data collisions during communication operations.
Innovation Solution
The implementation of a camera system with a camera communicator and controller that transmit requests to accessory apparatuses to determine if communication should be stopped, using distinct communication paths for urgent and non-urgent communications, and employing second communication connection switches to manage communication states, thereby reducing power consumption and avoiding data collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the entire imaging system is put into sleep state to reduce power consumption, then power consumption is reduced, but accessories that do not require communication cannot be identified and may experience data loss or communication issues
Solution Approach 1:
The imaging system is segmented into multiple components (camera body, interchangeable lens, intermediate adapter) with independent communication capabilities. The camera controller can selectively control communication states of each accessory rather than putting the entire system into sleep mode, allowing accessories without communication requirements to remain in a stable state while reducing overall power consumption.
Solution Approach 2:
The communication control mechanism dynamically adjusts the communication state of each accessory based on its specific requirements. The camera controller transmits requests to accessories and receives responses to determine whether to stop communication, enabling flexible adaptation to different accessory types and their communication needs, thus maintaining reliability while optimizing power consumption.
2Reliability
If communication is maintained with all accessories to ensure reliability, then communication reliability is maintained, but power consumption increases due to unnecessary communication with accessories that do not require it
Solution Approach 1:
Instead of maintaining communication with all accessories (excessive action), the system applies partial action by selectively maintaining communication only with accessories that require it. The camera controller transmits communication control requests to each accessory and bases the decision to continue or stop communication on the received responses, thereby avoiding unnecessary power consumption while ensuring reliability for accessories that need communication.
3Use of energy by moving object
If the intermediate adapter is put into power saving state when specific lens is identified, then power consumption is reduced, but operation members requiring communication cannot function properly
Solution Approach 1:
The system employs feedback mechanisms where the camera controller transmits communication control requests to the intermediate adapter and receives responses indicating whether communication should be stopped. Based on this feedback, the controller dynamically adjusts the communication state, ensuring that operation members remain functional when needed while allowing power saving when communication is not required.

AI summary
An imaging apparatus to which a plurality of accessory apparatuses are attachable includes a camera communicator configured to provide a communication path with each of the plurality of accessory apparatuses, and a camera controller configured to communicate with the plurality of accessory apparatuses via the camera communicator. The camera controller transmits a first request to the plurality of accessory apparatuses, receives first information corresponding to whether or not to stop a communication with the imaging apparatus from each of the plurality of accessory apparatuses that have received the first request, and controls a communication with each of the plurality of accessory apparatuses according to the first information.
