3D Display Image Synchronization Using Timestamp Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display synchronization methods often fail to accurately align left-eye and right-eye image frames due to time deviations, leading to misjudgment of image frames and potential user discomfort.
Innovation Solution
An image synchronization method and apparatus that select left-eye and right-eye image frames based on system time and timestamps, ensuring precise alignment by selecting frames with the closest timestamps, thereby eliminating synchronization errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If left-eye and right-eye image frames are selected independently based on system time, then the selection process is simple, but synchronization accuracy deteriorates due to time deviations between frames
Solution Approach 1:
The patent implements feedback by using the timestamp of the selected left-eye image frame to guide the selection of the right-eye image frame. The system selects the right-eye frame whose timestamp matches the left-eye frame's timestamp, creating a feedback loop that ensures accurate synchronization while maintaining operational simplicity.
2Measurement precision
If frames are selected using closest timestamp matching, then synchronization precision is improved, but the complexity of the selection process increases
Solution Approach 1:
The patent applies preliminary action by pre-organizing image frames with their timestamps and establishing a clear selection criterion (matching timestamps) before the actual synchronization process. This preparation work simplifies the selection process while maintaining high precision, as the system only needs to match pre-assigned timestamps rather than performing complex real-time analysis.
3Ease of manufacture
If conventional synchronization methods are used, then the system is easy to implement, but misalignment of image frames occurs leading to user discomfort
Solution Approach 1:
The patent introduces timestamps as an intermediary element that mediates between the left-eye and right-eye image frames. By using timestamps as a common reference point, the system achieves reliable frame alignment without complex implementation, as the timestamp acts as a simple yet effective mediator that connects both eye's frames accurately.

AI summary
An image synchronization method for a three-dimensional (3D) display apparatus is provided. The method includes steps of: receiving a plurality of first-eye image frames and a plurality of second-eye image frames; selecting a first image frame from the first-eye image frames according to a system time; selecting a second image frame from the second-eye image frames according to a timestamp of the first image frame; and outputting the first image frame and the second image frame.
