Binocular Hologram Transmission Using Overlap Region Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatial light modulators in binocular holographic displays have limited maximum diffraction angles due to manufacturing constraints, resulting in insufficient fields of view for both eyes, and there is a need for efficient compression and transmission of large and random hologram data without loss or delay.
Innovation Solution
Determine left-eye and right-eye hologram regions based on gaze information to create transmission hologram data corresponding to an overlap binocular region, reducing duplicate data transmission by generating and transmitting data for overlapping regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate left-eye and right-eye hologram data are transmitted, then binocular holographic display quality is improved, but transmission bandwidth requirement increases
Solution Approach 1:
The patent merges the transmission of left-eye and right-eye hologram data by identifying and transmitting only the difference data between the two views. Instead of separately transmitting complete hologram datasets for both eyes, the system combines the data streams and transmits only the incremental differences, thereby reducing total bandwidth consumption while maintaining binocular display quality.
Solution Approach 2:
The patent extracts and transmits only the essential difference information between left-eye and right-eye hologram data. By analyzing the commonalities and differences in the holographic content for each eye, the system extracts only the unique differential data that needs to be transmitted, eliminating redundant information and reducing transmission requirements.
2Quantity of substance
If hologram data is compressed to reduce transmission size, then bandwidth efficiency is improved, but data loss or quality deterioration occurs
Solution Approach 1:
The patent extracts only the differential information between left-eye and right-eye hologram data for transmission. By transmitting only the essential difference data rather than compressing the complete datasets, the system achieves size reduction without applying lossy compression algorithms that would deteriorate hologram quality.
Solution Approach 2:
The patent uses one hologram dataset as a reference and transmits only the differences from that reference. This copying approach allows the receiving end to reconstruct both left-eye and right-eye holograms with high fidelity by applying the differential data to the reference, avoiding quality loss associated with traditional compression methods.
3Reliability
If real-time hologram data transmission is implemented, then service quality is improved, but transmission delay increases due to large data volume
Solution Approach 1:
The patent extracts and transmits only the differential data between left-eye and right-eye holograms, dramatically reducing the total data volume that needs to be transmitted in real-time. This extraction of essential difference information maintains service quality while minimizing transmission delay by reducing the bandwidth burden.
Solution Approach 2:
The patent performs preliminary analysis to identify commonalities and differences between left-eye and right-eye hologram data before transmission. By pre-processing the data to extract differential information and prepare compression schemes in advance, the system reduces the amount of data requiring real-time transmission, thereby minimizing delay while maintaining service quality.

AI summary
A method and an apparatus for transmitting hologram data in binocular holographic display are disclosed. The method comprises obtaining left-eye gaze information and right-eye gaze information on a viewing window plane of the binocular holographic display based on pupil images of a user of the binocular holographic display; determining a left-eye hologram region and a right-eye hologram region on a hologram plane of the binocular holographic display based on the left-eye gaze information, the right-eye gaze information, and distance information between the viewing window plane and the hologram plane; and creating transmission hologram data corresponding to one binocular hologram region including an overlap hologram region, in which the left-eye hologram region and the right-eye hologram region overlap each other, based on input hologram data.
