Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote control devices for digital cameras face challenges in minimizing power consumption during wireless communication, particularly with Bluetooth Low Energy, as existing systems do not efficiently manage connection and disconnection based on user operations, especially in low-power consumption modes like Bluetooth Low Energy, and require further reduction in power consumption for high-power consumption communications.
Innovation Solution
The implementation of an imaging apparatus with a communication unit that allows for controlled disconnection of Bluetooth Low Energy communication based on signal content received from an external apparatus, enabling efficient power management by disconnecting communication during operations that do not require continuous connectivity, such as bulb imaging, to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Bluetooth Low Energy communication is used for remote control, then power consumption is reduced compared to wireless LAN, but connection management becomes critical to minimize energy usage
Solution Approach 1:
The imaging apparatus automatically manages Bluetooth connection states by determining whether to maintain or disconnect based on imaging mode detection. The system self-regulates communication continuity without requiring manual user intervention, enabling automatic disconnection in single-shot modes and continuous connection in continuous imaging modes, thus reducing power consumption while maintaining operational ease
Solution Approach 2:
The connection state of Bluetooth communication is made dynamic rather than static. The system adaptively changes connection status based on real-time imaging mode requirements, transitioning between connected and disconnected states to optimize power consumption while ensuring connectivity is available when needed for remote operation
2Speed
If continuous connection is maintained for remote control operations, then operational responsiveness is improved, but power consumption increases
Solution Approach 1:
Instead of maintaining continuous connection, the system employs periodic connection management where Bluetooth communication is activated only during periods when imaging operations are expected (based on mode detection) and deactivated during periods when remote control is not needed. This periodic activation pattern reduces overall power consumption while maintaining operational responsiveness when required
3Adaptability or versatility
If disconnection time is controlled for bulb imaging mode, then user operation flexibility is improved, but communication management complexity increases
Solution Approach 1:
The system automatically determines appropriate disconnection timing based on detected imaging modes without requiring complex user configuration. By self-managing the disconnection logic according to predefined mode characteristics (single-shot vs. continuous imaging), the system provides user flexibility in operation while avoiding the complexity of customizable disconnection settings

AI summary
An imaging apparatus includes an imaging unit, a communication unit that communicates with an external apparatus, and a control unit that controls the imaging apparatus with any one of a plurality of imaging modes using the imaging unit. The control unit controls the imaging unit based on content of a signal received from the external apparatus. The control unit enables transmission of information representing that communication via the communication unit is disconnectable to the external apparatus, based on the content of the received signal.
