Multi-Controller Camera Shooting Logic for Missed-Shot Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote photography systems face challenges in controlling autofocus and shooting operations of multiple digital cameras simultaneously, leading to missed shots due to conflicts when photographers send commands from different control apparatuses, resulting in inconsistent timing and missed opportunities.
Innovation Solution
A control system that allows multiple control apparatuses to coordinate their commands by ensuring that autofocus and shooting operations of an image capturing apparatus start and continue only when instructions from all control apparatuses are aligned, and stop when all commands to do so are received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital camera accepts shooting start commands from multiple control apparatuses independently, then each photographer can control the camera from their own device, but the camera cannot accept commands from multiple control apparatuses simultaneously leading to missed shots
Solution Approach 1:
The patent introduces a mediator mechanism that manages commands from multiple control apparatuses. When a shooting start command is received from any control apparatus, the camera enters a state where it continues shooting until stop commands are received from all control apparatuses that sent start commands. This intermediary control logic resolves the contradiction by allowing multiple photographers to control the camera independently while ensuring reliable shot capture through coordinated command management.
Solution Approach 2:
The camera performs preliminary action by entering a continuous shooting state upon receiving the first shooting start command. This preliminary state preparation ensures that when subsequent stop commands are received from all control apparatuses, the camera is already ready to capture shots reliably, eliminating the need for repeated start commands and preventing missed shots.
2Ease of operation
If a digital camera performs autofocus operations in response to commands from one control apparatus, then autofocus can be controlled remotely, but the camera does not accept autofocus start commands from other control apparatuses during ongoing operations causing photographers to miss shots
Solution Approach 1:
The patent applies the intermediary principle to autofocus control by implementing a command management system that tracks autofocus start commands from multiple control apparatuses. When autofocus is initiated from any control apparatus, the camera maintains autofocus operation until stop commands are received from all control apparatuses that sent start commands. This ensures reliable focus acquisition while allowing multiple photographers to control autofocus independently.
Solution Approach 2:
The camera ensures continuity of useful action by maintaining autofocus operations continuously until stop commands are received from all control apparatuses. This continuous operation prevents focus loss during multi-photographer scenarios, ensuring that the camera remains ready to capture shots reliably while accommodating independent control from multiple devices.
3Adaptability or versatility
If a photographer sends shooting start commands from one control apparatus while another photographer sends commands from a different control apparatus, then multiple photographers can control the camera, but the camera rejects commands from the second control apparatus resulting in missed shots
Solution Approach 1:
The patent implements an intermediary command management system that handles shooting commands from multiple control apparatuses. When shooting start commands are received from any control apparatus, the camera enters a state where it continues shooting until stop commands are received from all control apparatuses that sent start commands. This intermediary mechanism enables multiple photographers to control the camera simultaneously without rejection of commands, maintaining high shot capture efficiency while supporting versatile multi-photographer operation.
Data Source
AI summary
A control system in which an image capturing apparatus is controlled by a plurality of control apparatuses, wherein each control apparatus includes a first communication unit that communicates with the image capturing apparatus, a first instruction unit that outputs an instruction to start or stop an autofocus operation, and a second instruction unit that outputs an instruction to start or stop a shooting operation. The image capturing apparatus includes a second communication unit, an image capturing device, an optical imaging system, and a control unit. When the instruction to start the shooting operation is first received from any one control apparatus, the control unit performs control to start the shooting operation, and continue the shooting operation until the instruction to stop the shooting operation is received from all of the control apparatuses.
