Video Stabilization via Dynamic Field of View Punchout Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videos captured by image capture devices in motion often appear jerky or shaky due to device motion, which existing stabilization methods fail to adequately address, particularly in terms of maintaining a stable field of view and minimizing distortion.
Innovation Solution
A system that stabilizes videos by using a punchout of visual content, including wide and linear field of view punchouts, where the linear field of view punchout is smaller than the wide field of view punchout, and switches between them based on stabilization performance information to maintain a straight line appearance without distortion, using a processor and electronic storage to facilitate stabilization.

Engineering Contradiction Analysis
1Area of stationary object
If a wide field of view punchout is used for stabilization, then the field of view coverage is improved, but distortion occurs causing straight lines to appear curved
Solution Approach 1:
The system dynamically switches between wide field of view punchout and linear field of view punchout based on scene content and motion characteristics. The processor analyzes stabilization performance information and automatically selects the appropriate punchout type, making the stabilization approach adaptive rather than static.
Solution Approach 2:
The system changes the field of view parameter by selecting different punchout types (wide vs. linear). The wide punchout provides broader coverage with distortion, while the linear punchout maintains straight line geometry with narrower coverage. This parameter switching allows optimization based on specific stabilization needs.
2Shape
If a linear field of view punchout is used for stabilization, then distortion is minimized keeping straight lines straight, but the field of view coverage is reduced
Solution Approach 1:
The system dynamically switches between wide field of view punchout and linear field of view punchout based on scene content and motion characteristics. The processor analyzes stabilization performance information and automatically selects the appropriate punchout type, making the stabilization approach adaptive rather than static.
Solution Approach 2:
The system changes the field of view parameter by selecting different punchout types (wide vs. linear). The wide punchout provides broader coverage with distortion, while the linear punchout maintains straight line geometry with narrower coverage. This parameter switching allows optimization based on specific stabilization needs.
3Stability of the object's composition
If existing stabilization methods are used, then motion artifacts are reduced, but the field of view stability and distortion minimization are not adequately addressed
Solution Approach 1:
The stabilization approach is segmented into two distinct modes: wide field of view punchout for maximum coverage and linear field of view punchout for distortion-free stabilization. The system divides the stabilization problem into these segments and selects the appropriate one based on real-time analysis of stabilization performance information.
Solution Approach 2:
The system dynamically switches between wide field of view punchout and linear field of view punchout based on scene content and motion characteristics. The processor analyzes stabilization performance information and automatically selects the appropriate punchout type, making the stabilization approach adaptive rather than static.

AI summary
A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. Different field of view punchouts, such as wide field of view punchout and linear field of view punchout, may be used to stabilize the video. Different field of view punchouts may provide different stabilization margins to stabilize the video. The video may be stabilized by switching between different field of view punchouts based on the amount of stabilization margin needed to stabilize the video.
