Vertigo Effect Video Generation Using Multi-Camera Zoom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recording videos with a vertigo effect are cumbersome, requiring manual camera movement and zooming, which can result in shaky footage and abrupt zoom transitions, and lack flexibility in subject selection and movement handling.
Innovation Solution
A system and method that use multiple cameras to capture images with varying zoom levels, allowing for the identification of objects and backgrounds, determination of a zoom level range, and generation of a video with a smooth vertigo effect, enabling flexible subject selection and handling of moving subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual zooming method is used to create vertigo effect, then the main subject remains the same size in the frame, but the physical movement of camera and manual zooming causes shaky footage and abrupt zoom transitions
Solution Approach 1:
The patent replaces the manual mechanical zooming operation with an automated electronic zooming system controlled by a processor. The processor automatically adjusts the zoom level based on detected subject position and movement, eliminating the need for manual camera movement and manual zooming operations that cause shaky footage and abrupt transitions.
Solution Approach 2:
The system performs self-adjustment by automatically detecting the subject in each frame and calculating the appropriate zoom level to maintain subject size consistency. The processor autonomously controls the zoom operation without requiring user intervention, thereby maintaining stable footage while achieving the vertigo effect.
2Manufacturing precision
If manual camera movement and zooming is performed to capture vertigo effect, then the main subject can remain the same size, but multiple attempts are required to capture stable video
Solution Approach 1:
The system autonomously detects the subject, calculates the optimal zoom level, and executes the zoom operation automatically for each frame. This self-service capability eliminates the need for multiple manual attempts to capture stable video, significantly reducing the time required to produce a quality vertigo effect video.
Solution Approach 2:
The automated system continuously processes each frame to maintain subject size consistency throughout the video sequence. By performing subject detection, zoom level calculation, and zoom execution continuously and automatically, the system ensures stable vertigo effect capture in a single continuous recording session.
3Adaptability or versatility
If physical movement of camera with manual zooming is used, then vertigo effect can be created, but abrupt zoom levels cause unrealistic generated output
Solution Approach 1:
The system employs feedback by continuously detecting the subject's position and size in each frame, then using this information to calculate and adjust the zoom level. This closed-loop control ensures smooth and realistic zoom transitions by adapting the zoom level based on actual subject characteristics and movement, preventing abrupt and unrealistic changes.
Solution Approach 2:
The zoom level is dynamically adjusted based on real-time subject detection results. The processor calculates the appropriate zoom level for each frame based on the detected subject size and position, creating smooth and natural-looking vertigo effect that adapts to the subject's movement and maintains realistic proportions throughout the video.
