Stereo Logo Insertion in Spatially Interleaved 3D Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional logo insertion techniques fail to effectively insert logos into stereo spatially interleaved 3D images, resulting in undesirable effects such as logo distortion.
Innovation Solution
A method for generating a stereo logo comprising stereo spatially interleaved logo pictures, which are arranged in a spatially interleaved format, allowing for detection and combination with the video image to produce an overlaid image suitable for storage, display, or distribution, by detecting the presence of stereo spatially interleaved pictures and applying appropriate down-sampling and formatting to ensure accurate representation in both stereo views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional logo insertion techniques are used on stereo spatially interleaved pictures, then the logo insertion process can be performed, but the logo becomes distorted and does not appear correctly in both stereo views
Solution Approach 1:
The logo picture is divided into two separate stereo views (left and right) that are processed independently. Each view receives the appropriate down-sampled logo portion, ensuring that the logo appears correctly in both stereo views without distortion. This segmentation allows the system to handle each eye's view separately, maintaining proper logo geometry in the spatially interleaved format.
Solution Approach 2:
Different regions of the logo picture are processed with different down-sampling factors according to their intended display location. The logo is down-sampled to different resolutions for the left and right stereo views based on the spatial interleaving scheme, ensuring that each local region of the logo maintains its intended size and quality in the final composite picture.
2Manufacturing precision
If a logo picture is down-sampled to fit into a spatially interleaved picture, then the logo can be inserted without distortion, but additional processing steps are required
Solution Approach 1:
The logo picture is down-sampled in advance before being inserted into the spatially interleaved picture. By performing the down-sampling operation beforehand, the system ensures that the logo fits correctly into the allocated space in both stereo views, eliminating the need for complex real-time scaling operations during the logo insertion process.
Solution Approach 2:
The system changes the resolution parameter of the logo picture by applying down-sampling operations. The logo is transformed from its original high resolution to a lower resolution that matches the requirements of the spatially interleaved stereo picture, ensuring proper display without distortion while simplifying the overall processing requirements.

AI summary
A method for inserting a logo into a stereo video image to generate an overlaid stereo image, the method comprising: detecting presence of stereo pictures in the video image and, when stereo pictures are detected, determining the 3D format of said stereo pictures, said 3D format being a stereo spatially multiplexed format; generating a stereo logo comprising stereo spatially multiplexed logo pictures including a representation of the logo, said stereo spatitally multiplexed logo pictures being arranged in said 3D format; and combining the stereo logo and the video image to generate the overlaid stereo image in said 3D format.
