Device-Orientation Framing for Panoramic Video Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually determining the framing of wide field of view videos, such as spherical or panoramic videos, is difficult and time-consuming due to the vast amount of visual content that needs to be presented.
Innovation Solution
Utilize device orientation, including user interactions with a mobile device such as rotation, zooming, and gestures, to determine framing information for video content, which is then provided to a video editing application for preliminary framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual framing methods are used for wide field of view videos, then framing precision can be achieved, but time consumption increases significantly
Solution Approach 1:
The patent replaces manual mechanical framing operations with an automated system that uses device orientation sensors (accelerometer, gyroscope, magnetometer) to automatically determine viewing direction and framing parameters. The system substitutes human manual adjustment with sensor-based automatic detection and calculation of optimal framing based on device orientation angles.
2Productivity
If automated framing is implemented, then time efficiency improves, but ease of operation may deteriorate due to complexity
Solution Approach 1:
The system enables self-service automatic framing by utilizing the mobile device's own built-in sensors (accelerometer, gyroscope, magnetometer) to automatically determine framing parameters without requiring external equipment or complex user configuration. The device serves itself by using its inherent sensor capabilities to perform framing operations automatically.
3Ease of operation
If device orientation is used for framing, then ease of operation improves through natural interaction, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by utilizing the mobile device's existing sensor system (originally designed for other purposes like screen orientation and step counting) for the additional function of video framing determination. The same accelerometer, gyroscope, and magnetometer used for general device orientation are repurposed to calculate viewing direction and framing parameters, avoiding the need for dedicated framing hardware.

AI summary
A video may include visual content having a progress length. A user may interact with a mobile device to set framings of the visual content at moments within the progress length. The framings of the visual content may be provided to a video editing application. The video editing application may utilize the framings set via the mobile device to provide preliminary framings of the visual content at the moments within the progress length.
