3D Processing Circuit OSD Depth Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D processing circuits and methods fail to effectively manage the placement of on-screen display (OSD) information in 3D images, leading to user eye fatigue due to inconsistent depth and focus requirements, as OSD elements do not inherently have depth information, causing distant images to eclipse near ones and necessitating constant focal length adjustments.
Innovation Solution
A 3D processing circuit and method that analyzes the original 3D image to determine key depth information, uses this to dynamically position OSD elements with depth, and superimposes them onto the original image, allowing for adjustable depth placement to align OSDs with key points in the image, thereby reducing user eye fatigue by maintaining consistent focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the subtitle is displayed on the top layer of the frame, then the subtitle is always visible and readable, but distant images eclipse the near image causing user eye fatigue
Solution Approach 1:
The patent applies the dynamics principle by making the OSD depth position dynamic rather than fixed. The OSD determining device adjusts the depth position of subtitles based on the depth of key points in the 3D image, allowing the subtitle to move between different depth layers (front layer, top layer, or original position) to match the visual focus requirements of the displayed content, thereby eliminating the need for constant focal adjustment and reducing eye fatigue
Solution Approach 2:
The patent changes the depth parameter of the OSD based on the analyzed key point depth information. By modifying the depth position parameter dynamically according to the image content, the system ensures subtitles remain readable while maintaining proper depth relationships with other objects, preventing the eclipse effect and associated eye strain
2Object-affected harmful factors
If the subtitle location is fixed at the minimum depth, then the subtitle does not eclipse other objects and follows daily life experience, but the user must constantly adjust focal length between distant focus and near subtitle causing eye fatigue
Solution Approach 1:
The system dynamically adjusts the OSD depth position based on real-time analysis of key point depth in the image. When key points are at different depths, the subtitle automatically repositions to an appropriate depth layer, eliminating the need for users to constantly refocus between near and far objects, thus reducing eye fatigue while preventing object eclipse
3Device complexity
If conventional OSD processing is used without depth information, then the processing is simple, but the OSD cannot align with key points in the 3D image leading to poor viewing experience
Solution Approach 1:
The patent applies preliminary action by performing depth analysis of the 3D image and determining appropriate OSD depth positions before the OSD is displayed. The image analyzing device extracts key point depth information in advance, and the OSD determining device pre-calculates the optimal depth position, ensuring the subtitle aligns properly with the visual focus of the image content without requiring complex real-time adjustments during display
