Multi-Camera Synchronization and Frame Fusion for Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-camera systems face challenges in achieving synchronized image capture and processing, leading to suboptimal image quality due to differences in camera characteristics and operational settings, which affects the output of 3D imaging and other applications.
Innovation Solution
A synchronized image capture and processing protocol is implemented in multi-camera systems, where a pair of cameras outputs synchronized frames, designating reference frames for adjustment and fusion to improve image quality, using an image processor to assess and merge frames from cameras with different characteristics, such as varying exposure times and pixel counts, to create an aggregate image with enhanced quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras with different characteristics are used to capture images, then the field of view and imaging flexibility are improved, but the image quality consistency and synchronization between cameras deteriorate
Solution Approach 1:
The patent applies parameter changes by adjusting exposure times, gain settings, and other imaging parameters for each camera based on their specific characteristics. The system dynamically modifies these parameters to ensure that images from cameras with different fields of view and specifications maintain consistent quality levels, resolving the contradiction between versatility and image quality consistency.
Solution Approach 2:
The system implements feedback mechanisms where image quality metrics are continuously monitored and used to adjust camera settings and processing parameters. This closed-loop control ensures that despite differences in camera characteristics, the output images maintain consistent quality across all cameras in the multi-camera system.
2Ease of operation
If cameras operate independently with different exposure times and settings, then the operational flexibility is improved, but the synchronization and image quality matching deteriorate
Solution Approach 1:
The patent employs dynamic parameter adjustment where exposure times and other settings are continuously adapted based on real-time scene conditions and camera performance. This dynamic approach allows cameras to maintain operational flexibility while ensuring synchronization through coordinated parameter changes across all cameras in the system.
Solution Approach 2:
The system implements a universal control mechanism that manages multiple cameras with different characteristics under a single synchronized framework. This multi-functional approach allows the system to handle diverse camera types and settings while maintaining consistent synchronization and quality standards across all imaging devices.
3Device complexity
If images from multiple cameras are processed separately, then the processing complexity is reduced, but the final image quality and coherence deteriorate
Solution Approach 1:
The patent merges image processing operations by combining images from multiple cameras through coordinated processing pipelines. This merging approach ensures that images captured by different cameras are processed together with consistent parameters and algorithms, maintaining coherence and high quality in the final composite image while managing processing complexity through integrated workflows.

AI summary
Techniques are disclosed for managing image capture and processing in a multi-camera imaging system. In such a system, a pair of cameras each may output a sequence of frames representing captured image data. The cameras' output may be synchronized to each other to cause synchronism in the image capture operations of the cameras. The system may assess image quality of frames output from the cameras and, based on the image quality, designate a pair of the frames to serve as a “reference frame pair.” Thus, one frame from the first camera and a paired frame from the second camera will be designated as the reference frame pair. The system may adjust each reference frame in the pair using other frames from their respective cameras. The reference frames also may be processed by other operations within the system, such as image fusion.
