Fisheye Image Display Layout for Edge Reflection Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images captured using fisheye lenses are prone to unintended reflections at the edges, which are difficult to detect due to distortion, making it hard for photographers to confirm their presence.
Innovation Solution
An electronic apparatus performs geometric conversion processes on specific regions of the image, including perspective projection conversion on the main display region and edges, generating a display image by superimposing edge images onto the main image to reduce distortion and facilitate reflection detection.

Engineering Contradiction Analysis
1Area of stationary object
If the fisheye image is displayed as it is or converted to equirectangular image, then the entire image can be displayed at once, but the objects at the edge are largely distorted making it difficult to confirm unintended reflections
Solution Approach 1:
The image is divided into a center region and edge regions. The center region is displayed with perspective projection conversion to minimize distortion for the main object, while the edge regions are displayed separately to show unintended reflections with reduced distortion. This segmentation allows different parts of the image to be optimized for their specific purposes.
Solution Approach 2:
Different conversion methods are applied to different regions of the image. The center region uses perspective projection conversion appropriate for the main object, while the edge regions use appropriate conversions to minimize distortion for reflection detection. This local quality approach ensures each region is displayed with the most appropriate distortion characteristics for its intended use.
2Manufacturing precision
If perspective projection conversion is performed on the entire fisheye image, then distortion is reduced, but the region to be displayed is limited and edge regions where reflections occur are not included
Solution Approach 1:
The image is segmented into a center region and edge regions, with each region being converted and displayed separately. This allows the center region to be optimized for the main object while the edge regions are optimized for showing reflections, thereby maintaining both distortion reduction and complete image coverage.
Solution Approach 2:
The solution moves from a single-region display approach to a multi-region display approach, effectively adding a spatial dimension to the display strategy. By displaying different regions with different conversion characteristics, the system overcomes the limitation of choosing between distortion reduction and complete coverage.
3Reliability
If the photographer views the captured image to confirm unintended reflections, then reflection detection is possible, but time is lost and the process is inefficient
Solution Approach 1:
The system performs preliminary processing by automatically generating a display image that highlights edge regions where unintended reflections are likely to occur. This preliminary action allows the photographer to quickly confirm reflections without manually examining the entire image, thereby reducing confirmation time while maintaining detection reliability.
Solution Approach 2:
The system provides visual feedback by displaying the processed image with edge regions appropriately converted, making unintended reflections easily identifiable. This feedback mechanism allows rapid confirmation of reflections without requiring extensive manual inspection, thus reducing time loss while ensuring reliable detection.
