Local Multi-View Display Eliminates Dead Zones via Observer Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-view image display apparatuses either create dead zones where observers cannot view accurate images due to repeated views at predetermined intervals or fail to provide the same image to observers at different locations, and require a large number of cameras and increased bandwidth.
Innovation Solution
A local multi-view image display apparatus that includes a location tracking unit to track the observer's location and a display unit to locally display a multi-view input image based on the tracking result, ensuring that each observer receives the correct left and right images corresponding to their position, thereby eliminating dead zones and providing a consistent image across different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If views are repeated at predetermined intervals using a lenticular sheet, then multiple views can be displayed, but dead zones are created where observers cannot view accurate images
Solution Approach 1:
The patent applies dynamics by making the displayed view dynamically change based on the observer's real-time location. The display unit switches between different views (first view, second view, third view) depending on whether the observer is in a first region, second region, or third region, eliminating static dead zones and ensuring continuous accurate 3D image availability.
Solution Approach 2:
The patent implements feedback by using a location tracking unit to continuously monitor the observer's location and adjusting the displayed view accordingly. The system receives location information, determines the current region, and selects the appropriate view to display, creating a closed-loop control system that eliminates dead zones through real-time adaptation.
2Adaptability or versatility
If a large number of cameras are used to increase the number of displayable views, then dead zones can be prevented, but device complexity and bandwidth requirements increase
Solution Approach 1:
The patent applies copying by using a single camera to capture one view and then generating multiple additional views through image rendering. The rendering unit creates second and third views by processing the captured image and depth map, eliminating the need for multiple physical cameras while achieving the same multi-view display capability.
Solution Approach 2:
The patent implements multi-functionality by making a single camera system perform the work of multiple cameras. The rendering unit enables one captured view to serve multiple purposes by generating multiple displayable views through computational processing, reducing hardware complexity while maintaining versatility.
3Adaptability or versatility
If a large number of cameras are used to capture multiple views, then comprehensive coverage is achieved, but bandwidth requirements increase
Solution Approach 1:
The patent applies copying by generating multiple view representations from a single captured image through rendering. Instead of transmitting multiple original camera feeds, the system transmits one captured view and generates additional views computationally, significantly reducing bandwidth requirements while maintaining comprehensive multi-view coverage.
