Imaging Control Device Synchronizes Multi-Camera Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging control systems fail to synchronize the imaging times of multiple cameras effectively, leading to defocused images due to varying auto focus times among devices.
Innovation Solution
An imaging control device that transmits an imaging preparation command to multiple cameras, receives preparation completion information, and then sends a captured image acquisition command, ensuring all cameras are focused before capturing images simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If imaging times are forcibly synchronized without considering different auto focus times, then imaging synchronization is improved, but image quality deteriorates due to defocused images
Solution Approach 1:
The system performs preliminary auto focus adjustment for each imaging device before the actual imaging operation. The control device sends an imaging preparation command that triggers auto focus, waits for completion confirmation from all devices, and only then issues the imaging command. This ensures each device is properly focused before synchronized imaging begins.
Solution Approach 2:
The system implements a feedback mechanism where each imaging device reports its preparation completion status back to the control device. The control device receives preparation completion information from each device and uses this feedback to determine when all devices are ready for synchronized imaging, ensuring both synchronization and focus quality.
2Manufacturing precision
If each imaging device captures image after auto focus completion, then image quality is improved, but imaging synchronization deteriorates due to different capture times
Solution Approach 1:
The system performs preliminary auto focus adjustment for all imaging devices before the actual imaging operation. By completing focus adjustment in advance and confirming readiness from all devices, the system ensures both focus quality and subsequent imaging synchronization without trade-offs.
Solution Approach 2:
The control device receives feedback from each imaging device indicating when auto focus is complete. This feedback allows the control device to coordinate the timing of the actual imaging command, ensuring all devices capture images at the same time while maintaining focus quality.
3Reliability
If imaging preparation command is transmitted to all devices, then imaging readiness is improved, but communication overhead increases due to multiple command exchanges
Solution Approach 1:
The imaging control process is segmented into distinct phases: an imaging preparation phase for auto focus adjustment, and an imaging execution phase for actual capture. This segmentation allows each phase to be managed independently with appropriate commands and confirmations, improving reliability while maintaining clear communication protocols.
Solution Approach 2:
The control device acts as an intermediary that coordinates between multiple imaging devices. It sends preparation commands, collects completion status from each device, and then issues the synchronized imaging command. This intermediary role simplifies the communication protocol by centralizing coordination logic.
