Multiview 3D Image OSD Positioning via Disparity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D TV systems limit viewers to a fixed 3D image view, and the display of on-screen displays (OSD) and closed captions can interfere with the 3D effect by being positioned incorrectly, potentially cutting off parts of these elements from the screen due to disparity between left and right images.
Innovation Solution
A method and apparatus for processing 3D images in a multiview system that involves receiving video and depth images for multiple views, calculating pixel disparities, and synthesizing OSDs and closed captions to ensure they are displayed at appropriate positions, preventing them from being cut off or interfering with the 3D effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If OSD and closed caption are displayed on 3D TV using legacy art, then the information can be shown to users, but the position (depth) of these elements vitiates the depth of 3D broadcasting or 3D image
Solution Approach 1:
The patent applies local quality by assigning different depth properties to different regions of the display. Specifically, the OSD and closed caption are placed in a first depth range while the 3D image content occupies a second depth range, creating spatial differentiation that preserves both information display and 3D effect integrity
Solution Approach 2:
The patent introduces depth as an additional dimension for organizing display elements. By utilizing the depth dimension (via disparity control) to separate OSD/closed caption from 3D content, it resolves the conflict between information display and 3D effect preservation
2Reliability
If a fixed view 3D image is displayed, then the 3D image can be shown clearly, but the viewer cannot freely select a preferred view
Solution Approach 1:
The patent implements dynamics by enabling the display system to adaptively switch between fixed view mode and multiview mode. The system can dynamically adjust the number of views and disparity values based on viewer preferences and content requirements, transforming a static display system into a flexible one
3Manufacturing precision
If multiview 3D image is displayed with calculated disparity, then the OSD can be positioned appropriately, but parts of OSD may still be cut off from the screen due to disparity between left and right images
Solution Approach 1:
The patent applies preliminary anti-action by proactively preventing OSD cutoff through careful disparity calculation and positioning. The system calculates appropriate disparity values and positions the OSD in a first depth range that prevents it from being cut off in either left or right view images, thereby preemptively avoiding the harmful effect of information loss

AI summary
A method for processing a 3-dimensional image including an additional object in a system providing a multi-view image according to one embodiment of the present invention comprises the steps of: receiving video images and depth images from a plurality of views; configuring one additional object of additional objects displayed in the video images from the plurality of views as a reference additional object; calculating disparity between pixels of an area in which the reference additional object is displayed and a video image, which is adjacent to an edge of the reference additional object; applying a disparity value, which is larger the or equal to a value of the calculated disparity, to the reference additional object, so as to combine the reference additional object with a first view video image and a second view video image; and formatting the first view video image and the second view video image, with which the reference additional object has been combined, as 3-dimensional images.
