Split-Screen Macro Photography for Easier Object Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-camera smartphones face challenges in precisely targeting small objects for macro photography due to occlusion by the device, making it difficult to direct the macro camera effectively.
Innovation Solution
A split screen view is implemented on the device, displaying a preview of the ultra-wide camera field of view alongside the macro camera field of view, with a differentiating element marking the object of interest, providing visual guidance for the user to align the macro camera with the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a macro camera with narrow field of view is used to capture small objects, then magnification is improved, but the ability to locate and align the object is worsened due to device occlusion
Solution Approach 1:
The display screen is segmented into multiple regions, with the first region showing the macro camera's narrow field of view and the second region showing the ultra-wide camera's wide field of view. This segmentation allows users to simultaneously see both the magnified view for precise measurement and the broader context for easy alignment and object location.
Solution Approach 2:
The ultra-wide camera acts as an intermediary that provides a wide field of view display region, helping users locate and align small objects before switching to or using the macro camera for detailed capture. This intermediary view solves the alignment difficulty caused by device occlusion when using only the narrow field of view macro camera.
2Ease of operation
If an ultra-wide camera is used to capture small objects, then ease of locating objects is improved, but magnification is worsened
Solution Approach 1:
The display is segmented to show both the ultra-wide camera view for object location and the macro camera view for magnification simultaneously. Users can first locate objects using the wide field of view in the second region, then switch to or reference the first region for detailed magnified views, eliminating the need to choose between location ease and magnification power.
3Measurement precision
If only a macro camera field of view is displayed, then magnification is maximized, but user guidance for alignment is worsened
Solution Approach 1:
The display screen is divided into segments where the first region shows the macro camera view for magnification while the second region shows the ultra-wide camera view providing contextual information. This segmentation ensures that context information is not lost while maintaining maximum magnification capability in the dedicated macro view region.
Solution Approach 2:
The solution adds a spatial dimension to the display by using multiple regions on the screen. Instead of losing context when maximizing magnification, the system presents information across different spatial dimensions (multiple display regions), allowing users to access both magnified details and broader context simultaneously without compromising either.
