VR Content Clipping via Dual-Range Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying wide-range video content, such as omnidirectional images, often include unnecessary objects like the photographer, and lack efficient techniques for generating VR content with a narrower range from omnidirectional images.
Innovation Solution
An electronic device with a display controlling unit, generating unit, and changing unit that allows for the display of a wider video range on one screen and a narrower range on another, enabling users to edit and change the video range interactively, effectively clipping unnecessary portions from the omnidirectional image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If omnidirectional image is displayed with wide video range, then immersion and realism are improved, but unnecessary objects like photographer appear in the image
Solution Approach 1:
The omnidirectional image is divided into multiple regions including a first region with a first video range and a second region with a second video range that is narrower. This segmentation allows the system to display different portions of the omnidirectional image simultaneously, enabling users to view both the immersive wide-range content and the clipped content without unnecessary objects like the photographer.
Solution Approach 2:
The patent introduces a dual-screen display approach where the first screen shows the wide video range for immersion and the second screen shows the narrow video range for clipping preview. This dimensional change from single-screen to multi-screen display enables users to compare and select the desired view without losing the immersive experience.
2Quantity of substance
If VR content with narrower range is generated from omnidirectional image, then data storage and processing loads are reduced, but existing methods lack efficient techniques for this conversion
Solution Approach 1:
The system performs preliminary clipping operations by displaying multiple regions with different video ranges before final VR content generation. Users can preview and select the desired clipped content on the second screen before the actual VR content is generated, making the conversion process more efficient and user-friendly.
Solution Approach 2:
The dual-screen display provides visual feedback to users about the clipping operation. The first image shows the original wide-range content while the second image shows the clipped narrow-range content, allowing users to see the effect of clipping in real-time and make informed decisions about the final VR content generation.
3Ease of operation
If display range is changed to follow orientation change of electronic device, then user interaction is improved, but operability becomes complex when editing VR content
Solution Approach 1:
The system implements dynamic display range adjustment that adapts to user needs. When a user performs a display range change operation, the system dynamically switches between displaying the first region with wide video range and the second region with narrow video range, providing flexible operability during VR content editing while maintaining ease of interaction.

AI summary
In an electronic device according to the present invention, on a first screen, a range of a part of a VR content having a first video range is displayed as a display range and the display range is changed in accordance with an orientation change of the electronic device or a display range change operation, and on a second screen, a first image with a second video range that is narrower than the first video range and a second image with a range outside of the second video range in the first video range are displayed side by side; an edited VR content including the second video range is generated; and the second video range is changed in accordance with a video range change operation in a state where the first image and the second image are being displayed on the second screen.
