Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle to efficiently transmit and manage wide-view images across multiple sites in real-time, particularly in applications requiring precise point-of-view control and storage of images with associated point-of-view information.
Innovation Solution
A communication system comprising an image capturing apparatus that captures wide-view images and an information processing system that receives, transmits, and stores these images in association with point-of-view information, allowing for precise control and display of specific areas within the wide-view images across communication terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wide-view images are transmitted in real-time across multiple sites, then remote communication capability is improved, but image management complexity and storage requirements increase
Solution Approach 1:
The patent segments the wide-view image into multiple regions of interest (ROIs) based on point-of-view information. Instead of transmitting the entire wide-view image, only the relevant portions are extracted and transmitted to communication terminals. This reduces the data volume while maintaining the ability to provide comprehensive remote communication across multiple sites.
Solution Approach 2:
The patent introduces an intermediary processing system that receives wide-view images, extracts regions of interest based on point-of-view information, and transmits only these extracted regions to communication terminals. This intermediary layer manages the complexity of image processing and data selection, simplifying the overall system architecture.
2Measurement precision
If wide-view images are stored with point-of-view information, then image retrieval precision is improved, but storage capacity requirements increase
Solution Approach 1:
The patent extracts only the necessary point-of-view information from the full wide-view image and stores this metadata separately. The actual image data is stored in a compressed format, and only the relevant portions are retrieved based on the point-of-view information. This extraction approach maintains precise retrieval capability while significantly reducing storage requirements.
Solution Approach 2:
Instead of storing the complete wide-view image data for all possible viewing angles, the patent stores only the necessary portions corresponding to actual point-of-view requests. This partial storage approach reduces the quantity of stored data while maintaining the ability to retrieve images with precise point-of-view information when needed.
3Productivity
If only specific areas of wide-view images are transmitted, then transmission efficiency is improved, but system complexity for area selection increases
Solution Approach 1:
The patent uses point-of-view information as a parameter to automatically determine which regions of the wide-view image need to be transmitted. By changing the parameter from transmitting the entire image to transmitting only specific regions based on point-of-view coordinates, the system achieves improved transmission efficiency. The complexity of area selection is reduced because the selection is automated based on standard point-of-view parameters.

AI summary
A system and a method, each of which: transmits video including a wide-view image having a wide angle of view to a communication terminal; and stores, in a predetermined storage destination, the wide-view image received from an image capturing apparatus that captures the wide-view image in response to an image capturing request, in association with point-of-view information for specifying a predetermined area of the wide-view image to be displayed, the predetermined area being designated at the communication terminal.
