Video Stabilization Viewing Window Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Downloading and stabilizing videos from image capture devices to computing devices is inconvenient and time-consuming, as it requires transferring large video files and applying stabilization post-transfer, which can be resource-intensive and slow.
Innovation Solution
A system that determines the placement of a viewing window for video stabilization based on position information during video capture, allowing for stabilization as the video is streamed, using a processor to define the viewing window before video information is obtained, and generating stabilized visual content by selecting specific extents within this window, thereby reducing data transfer and stabilization time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If video stabilization is performed after downloading the video to a computing device, then the video can be stabilized with high precision, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent determines the viewing window for video stabilization based on position information obtained during video capture, before the video is transferred to the computing device. This preliminary determination of the viewing window allows stabilization to be performed more efficiently during or after transfer, rather than requiring complete video download and extensive post-processing, thus reducing time loss while maintaining stabilization quality
2Reliability
If the entire video is transferred to a computing device for processing, then complete video data is available for stabilization, but data transfer time and resource consumption increase
Solution Approach 1:
The patent extracts only the necessary position information from the video capture process to determine the viewing window for stabilization. By obtaining position information during capture and using it to define the viewing window before full video transfer, the system avoids transferring complete video data for stabilization processing, thus reducing data transfer time and resource consumption while maintaining the ability to produce stabilized video output
Solution Approach 2:
The viewing window is determined in advance based on position information obtained during video capture. This preliminary determination allows the system to prepare stabilization parameters before the video is fully transferred to the computing device, enabling more efficient processing and reducing the time and resources needed for complete video transfer and subsequent stabilization

AI summary
Positions of an image capture device during capture of a video may be transferred to a computing device before the video is transferred to the computing device. The positions of the image capture device may be used to determine a viewing window for the video before the video is obtained. The viewing window may be used to present a stabilized view of the video when the video is obtained. For example, a stabilized view of the video may be presented as the video is streamed to the computing device.
