Electronic Device Selective Image Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Omni-directional image transmission and reception in electronic devices leads to excessive data bandwidth and processor load due to the large data size of capturing images in all directions, causing network and resource overload.
Innovation Solution
The electronic device processes and transmits image data differently based on the user's intended view direction, using multiple qualities of data (high, medium, and low) to reduce communication load, where only relevant data is transmitted and displayed, optimizing data quality according to the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If omni-directional image data is transmitted in full quality to all directions, then complete view coverage is achieved, but data bandwidth consumption and processor load become excessive
Solution Approach 1:
The patent applies local quality by transmitting high-quality image data only for the user's current field of view direction, while transmitting lower-quality or reduced-resolution data for other directions. This selective quality approach ensures that the user experiences high-quality images where needed while significantly reducing overall data bandwidth consumption and processor load.
2Measurement precision
If high-quality image data is transmitted for all view directions, then image quality is maintained, but network load and resource consumption increase
Solution Approach 1:
The system transmits high-quality image data localized to the user's current field of view while using lower quality data for peripheral or non-viewed directions. This resolves the contradiction by maintaining high image quality where the user is actually looking while reducing network load and energy consumption overall.
Solution Approach 2:
Instead of transmitting complete high-quality data for all 360 degrees, the system transmits only the necessary portion corresponding to the user's current view direction at high quality, with partial or reduced quality data for other directions. This partial action approach maintains necessary image quality while reducing resource consumption.
3Adaptability or versatility
If complete omnidirectional image data is processed and displayed, then full directional coverage is provided, but device complexity and processing requirements increase
Solution Approach 1:
The device processes and displays high-quality image data only for the relevant field of view direction while using reduced processing for other directions. This maintains adaptability to different view directions while significantly reducing device complexity and processing requirements through selective processing based on user orientation.
