2D Video to 3D Conversion via Time-Delayed Stream Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for converting two-dimensional content into three-dimensional content for display require specialized software and hardware, including cumbersome three-dimensional glasses, and lack efficient means to convert any source of 2D content into 3D without sophisticated tools.
Innovation Solution
A system and process that converts two-dimensional video into stereoscopic three-dimensional video using a virtual reality headset or wearable device by dividing the video into left and right streams with a specified time delay, allowing for real-time 3D display without the need for specialized glasses, applicable to various 2D video sources including online, streamed, and live content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized software and hardware including 3D glasses are used to convert 2D content to 3D content, then stereoscopic 3D effects can be achieved, but the system becomes cumbersome and requires sophisticated tools
Solution Approach 1:
The patent extracts and eliminates the need for specialized 3D glasses and complex conversion software by using a dual-camera system that directly captures stereoscopic images. The two cameras mounted on a smartphone or similar device capture left and right eye views simultaneously, removing the intermediary conversion step and the need for external 3D viewing accessories.
Solution Approach 2:
The system makes the smartphone itself multi-functional by integrating both 2D and 3D capture capabilities into a single device. The same smartphone can function as a regular camera for 2D photos and videos, and simultaneously as a 3D camera when the dual-camera mode is activated, eliminating the need for separate specialized equipment.
2Reliability
If 3D glasses are used for viewing, then stereoscopic images can be displayed, but the viewing experience becomes cumbersome
Solution Approach 1:
The patent removes the requirement for external 3D glasses by using the smartphone's built-in display to present the stereoscopic images directly. The display shows side-by-side or alternating left and right eye images, which the viewer perceives as 3D through the smartphone screen itself, eliminating the need for additional viewing accessories.
3Adaptability or versatility
If conventional 2D to 3D conversion methods are used, then existing content can be converted, but efficient conversion of any 2D content source without sophisticated tools is lacking
Solution Approach 1:
The system performs preliminary action by capturing both left and right eye views simultaneously at the moment of recording, rather than attempting to convert 2D content to 3D afterward. This upfront capture of stereoscopic data eliminates the need for complex post-processing conversion algorithms and software.

AI summary
Described here are systems, devices, and method for converting a two-dimensional video sequence into first and second video sequences for display at first and second display areas of a single display. In some embodiments, a two-dimensional video image sequence is received at a mobile device or wearable headset device. The two-dimensional video image sequence may be split into first and second video image sequences such that a first video image sequence is output to the first display area and a second video image sequence different from the first video image sequence is output to the second display area. The first and second video image sequences may be created from the two-dimensional video image sequence.
