Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote support systems face challenges in transmitting high-quality moving images from wearable devices to remote computers due to bandwidth limitations, where the regions of interest for the supporter may not align with the regions captured at high quality by the worker's device.
Innovation Solution
A system allowing the reception terminal to designate a region of interest, with the transmission terminal processing the image to maintain quality in this region while reducing quality in others, optimizing data transmission based on available bandwidth.

Engineering Contradiction Analysis
1Quantity of substance
If the transmission terminal transmits the moving image after optimizing quality in accordance with bandwidth, then the data amount is reduced to fit bandwidth, but the image quality is degraded
Solution Approach 1:
The moving image is divided into multiple regions based on importance. The region-of-interest designation unit segments the image into a region of interest (first region) and other regions (second region). This segmentation allows different quality levels to be applied to different parts of the image, reducing overall data amount while preserving quality where needed.
Solution Approach 2:
Different quality levels are applied to different regions of the image. The region of interest is transmitted at higher quality (first frame rate or higher resolution) while other regions are transmitted at lower quality (second frame rate or lower resolution). This local quality approach ensures that bandwidth is used efficiently while maintaining high quality in critical areas.
2Manufacturing precision
If the transmission terminal sets high frame rate for specific region, then the region quality is improved, but the region may not match the supporter's desired observation area
Solution Approach 1:
Instead of the transmission terminal determining which region to transmit at high quality, the reception terminal (supporter's device) designates the region of interest. This inversion of control allows the supporter to flexibly select any region they wish to observe in high quality, adapting to their specific needs rather than being constrained by the worker's perspective.
Solution Approach 2:
The region-of-interest designation unit at the reception terminal sends feedback information about the desired region back to the transmission terminal. This feedback mechanism enables dynamic adjustment of the transmitted image quality based on the supporter's real-time requirements, ensuring adaptability to various observation needs.
3Manufacturing precision
If the entire moving image is transmitted at high quality, then the image quality is maintained, but the bandwidth requirement exceeds available capacity
Solution Approach 1:
Instead of transmitting the entire image at high quality, only a partial region (the region of interest) is transmitted at high quality. The first frame rate is applied to the region of interest while the second, lower frame rate is applied to other regions. This partial action approach maintains acceptable overall quality while significantly reducing bandwidth consumption.

AI summary
A moving image transmission/reception system which includes a transmission terminal and a reception terminal connected to each other via a communication line, wherein the transmission terminal transmits, to the reception terminal, a moving image obtained by an imaging unit. The reception terminal designates a specific area of interest from the moving image received from the transmission terminal, and transmits information relating to the area of interest to the transmission terminal. Upon reception of the information relating to the area of interest from the reception terminal, the transmission terminal creates, on the basis of the information relating to the area of interest, a corrected moving image having undergone a process of cutting out a moving image portion in the area of interest from an original moving image obtained by the imaging unit, or a process of degrading the quality of a moving image portion outside the area of interest as compared to the original moving image, and transmits the corrected moving image to the reception terminal.
