Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic image systems require significant time and bandwidth to receive focal length-specific images, especially when real-time adjustments are needed based on user viewpoint changes, leading to suboptimal immersion and space perception.
Innovation Solution
A stereoscopic image generating device that tracks user motion and viewpoint to directly extract and up-scale focal length-specific image data from an external server, using a binocular display and variable focus optical system to provide multifocal VR images synchronized with user gaze adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If focal length-specific stereoscopic images are received from an external server to create multifocal stereoscopic images, then the sense of space and immersion is improved, but the time required and communication bandwidth increase
Solution Approach 1:
The patent extracts only the necessary portion of the stereoscopic image data by identifying and processing a specific viewpoint region within the received image. Instead of transmitting or processing complete focal length-specific images, the system extracts only the relevant viewpoint area, significantly reducing data transmission time and bandwidth requirements while maintaining the multifocal immersion effect
Solution Approach 2:
The patent segments the stereoscopic image processing into distinct components: receiving the base image, identifying the viewpoint region, extracting the specific area, and generating the multifocal effect. This segmentation allows the system to process only necessary portions of the image data rather than handling complete focal length-specific images, reducing overall processing time and communication overhead
2Adaptability or versatility
If stereoscopic images are received from an external server in real time depending on user viewpoint changes, then the sense of space and immersion is improved, but the time required to receive images further increases
Solution Approach 1:
The patent performs preliminary processing by pre-identifying and pre-extracting viewpoint regions from the received stereoscopic image. This preliminary extraction creates a ready-to-use viewpoint-specific image data set that can be quickly rendered and displayed when viewpoint changes occur, eliminating the need for time-consuming real-time image reception and processing from external servers
Solution Approach 2:
The patent creates a local copy of the necessary image data by extracting and storing viewpoint-specific regions within the user device. This local copy allows the system to rapidly generate multifocal stereoscopic images based on viewpoint changes without requiring continuous real-time communication with external servers, significantly reducing latency while maintaining adaptive real-time performance

AI summary
Disclosed is a method of operating a stereoscopic image generating device communicating with a rendering server device including obtaining first tracking data by tracking a motion of a user during a reference time interval, obtaining second tracking data by tracking a viewpoint of the user during the reference time interval, providing the first tracking data to the rendering server device, receiving one or more focus image data corresponding to the first tracking data from the rendering server device, extracting one or more areas corresponding to the tracked viewpoint from each of the one or more focus image data based on the second tracking data, generating multifocal virtual reality (VR) image data by up-scaling the extracted one or more areas, and visually providing, by a display device of the stereoscopic image generating device, the multifocal VR image data to the user.
