Video Region Switching for Multi-Subject Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display methods struggle to efficiently cut out and switch between video regions in a captured video, limiting the ability to capture zoomed-in videos of multiple subjects without repositioning the imaging apparatus.
Innovation Solution
A display method that automatically sets multiple candidates for a set region within a reference region, allows user selection of a recording region, and enables switching between these regions to capture and display specific video segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video regions are manually set and switched, then zoomed-in videos of multiple subjects can be obtained, but the operation complexity and time consumption increase
Solution Approach 1:
The imaging apparatus automatically detects feature portions in the captured video and autonomously sets multiple candidate regions without requiring manual user input. The system serves itself by performing region detection, candidate generation, and automatic selection based on imaging conditions, eliminating the need for complex manual operations while maintaining the ability to capture multiple subjects
Solution Approach 2:
The system pre-generates multiple candidate regions based on feature portion detection before the actual recording begins. By preparing these candidate regions in advance and storing them as selectable options, the system enables quick switching between subjects during recording without requiring time-consuming manual region setting at the moment of capture
2Adaptability or versatility
If the imaging apparatus is repositioned to capture different subjects, then zoomed-in videos can be obtained, but the stability and continuity of the imaging position deteriorate
Solution Approach 1:
Instead of changing the physical position of the imaging apparatus in space to capture different subjects, the system transitions to a digital dimension by extracting and displaying multiple candidate regions from the single captured video frame. This dimensional shift allows virtual zooming into different subjects while maintaining the imaging apparatus at a stable, fixed position
Solution Approach 2:
The system segments the single captured video frame into multiple candidate regions, each containing a different subject or feature portion. By dividing the overall image into selectable segments, the system enables capture of zoomed-in views of multiple subjects from a single stable imaging position without requiring physical repositioning
3Productivity
If automatic region setting is implemented, then operation efficiency improves, but the precision and accuracy of region selection may deteriorate
Solution Approach 1:
The system provides feedback to the user by displaying multiple candidate regions with their detected feature portions and allowing the user to review these options before final selection. This feedback mechanism enables the user to verify the automatic detection results and make informed selections, ensuring both operational efficiency and selection accuracy
Solution Approach 2:
The system dynamically adjusts the candidate region settings based on detected imaging conditions such as focus position, exposure amount, and white balance. By making the region detection and candidate generation adaptive to changing imaging conditions, the system maintains high precision in region selection while preserving automatic operation efficiency

AI summary
Provided is a more useful method as a display method of a video in which a part of a captured video is cut out and the cut-out video can be switched.A display method of displaying a video captured by an imaging apparatus includes a setting step of automatically setting a plurality of candidates for a set region in a reference region which is an imaging region of a reference video, a selection step of selecting a recording region, which is a region of a record video to be recorded, from among the plurality of candidates for the set region based on a selection of a user, and a switching step of reselecting the recording region from among the plurality of candidates for the set region to switch the recording region after the selection step is performed.
