Dual-Camera Switching for Stable Super Macro Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face instability in photographing modes like super macro mode due to reduced accuracy of wide-angle camera parameters when switching between cameras without a laser sensor, leading to poor shooting stability.
Innovation Solution
A method for switching cameras based on dual-restriction conditions using parameters from both the first and second cameras, including distance and brightness thresholds, to ensure accurate switching and maintain stability in photographing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic device switches cameras based only on the parameter of the second camera, then the switching process is simple, but the accuracy of distance measurement deteriorates, causing instability in super macro mode
Solution Approach 1:
The patent combines the parameter data from both the first camera (ultra wide-angle camera) and the second camera (wide-angle camera) to make the camera switching decision. By merging the distance parameters from both cameras, the system achieves more accurate distance measurement and improves the stability of super macro mode, resolving the contradiction between simple switching logic and accurate measurement.
2Area of moving object
If the electronic device uses the ultra wide-angle camera for close-up shooting, then the field of view is expanded, but the focusing accuracy deteriorates when the object distance is less than the effective focusing distance
Solution Approach 1:
The patent introduces a feedback mechanism where the system continuously monitors the object distance using parameters from both cameras. When the object distance falls below the effective focusing distance of the ultra wide-angle camera, the system receives feedback and switches to the wide-angle camera, thereby maintaining focusing accuracy while preserving the expanded field of view capability.
3Adaptability or versatility
If the electronic device automatically exits super macro mode frequently, then the system responds to distance changes, but the stability of the photographing mode deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing the effective focusing distance threshold for the ultra wide-angle camera and pre-configuring the dual-camera parameter verification mechanism. This allows the system to proactively maintain super macro mode stability by verifying distance parameters before switching occurs, reducing unnecessary mode exits while still responding appropriately to genuine distance changes.
