Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independently setting exposure settings for different image sensors, then each sensor can be optimized for its specific field of view, but mismatch in visual characteristics occurs leading to uneven look when combined
Solution Approach 1:
The patent merges the exposure control of multiple image sensors by applying a single group exposure setting determined from one lens's field of view to multiple image sensors. This combines the exposure parameters into one unified control mechanism, ensuring visual characteristic matching across sensors while maintaining the ability to capture content from multiple fields of view.
2Manufacturing precision
If using single lens exposure mode with group exposure setting, then visual characteristics match across sensors, but cannot optimize exposure for each sensor's specific luminance conditions
Solution Approach 1:
The system dynamically switches between single lens exposure mode (using group exposure setting for visual matching) and multi-lens exposure mode (using individual exposure settings for optimization). This dynamic adjustment allows the system to adapt to different capture scenarios, choosing the appropriate exposure strategy based on whether visual consistency or luminance optimization is the priority.
3Adaptability or versatility
If using multi-lens exposure mode with individual exposure settings, then exposure can be optimized for each sensor's luminance, but visual characteristics mismatch causing uneven look when combined
Solution Approach 1:
The system dynamically switches between single lens exposure mode (using group exposure setting for visual matching) and multi-lens exposure mode (using individual exposure settings for optimization). This dynamic adjustment allows the system to adapt to different capture scenarios, choosing the appropriate exposure strategy based on whether visual consistency or luminance optimization is the priority.
4Ease of operation
If adding graphical user interface for exposure mode switching, then user can control exposure settings, but device complexity increases
Solution Approach 1:
The graphical user interface uses a unified exposure mode element that serves multiple functions: selecting between single lens and multi-lens exposure modes, and in multi-lens mode, selecting which lens's luminance to use for group exposure settings. This multi-functional design provides comprehensive control capabilities while minimizing the number of interface elements required.

AI summary
An image capture device may include multiple lenses and multiple image sensors. The image capture device may operate in a multi-lens exposure mode or a single lens exposure mode. In the multi-lens exposure mode, the exposure setting of individual image sensors may be determined based on luminance of the scene included within the field of view of corresponding lenses. In the single lens exposure mode, the group exposure setting for all image sensors may be determined based on luminance of the scene included within the field of view of a single lens. The user may change the operation of the image capture device between the multi-lens exposure mode and the single lens exposure mode by interacting with an exposure mode element presented on an electronic display.
