Display Terminal Point-of-View Overlay for Wide-View Image Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users viewing recorded wide-view images struggle to determine which area of the image was being displayed on a communication terminal at the time of recording, making it difficult to identify areas of interest.
Innovation Solution
A display terminal and method that receive an instruction to play back a wide-view image and control a display to show a predetermined-area image, based on point-of-view information specifying the area within the wide-view image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a wide-view image is displayed without point-of-view information, then the entire wide area is visible, but users cannot identify which specific area was being displayed at the communication terminal
Solution Approach 1:
The system pre-processes the wide-view image to extract and embed point-of-view information indicating the displayed area before distribution to communication terminals. This preliminary action ensures that when the image is played back on the display terminal, the area information is already available for automatic overlay, eliminating the need for users to manually analyze the wide-view image to determine what was being displayed.
2Loss of information
If point-of-view information is overlaid on the wide-view image, then users can easily identify the displayed area, but the image processing complexity increases
Solution Approach 1:
The system separates the wide-view image processing into distinct segments: (1) extracting point-of-view information from the wide-view image during pre-processing, (2) distributing the image with embedded area information to communication terminals, and (3) automatically overlaying the area information on the display terminal during playback. This segmentation simplifies the overall complexity by distributing processing tasks across different stages and devices.
Solution Approach 2:
The system introduces an intermediary processing stage at the communication terminal that receives the wide-view image, extracts point-of-view information, and prepares it for overlay. This intermediary approach reduces the burden on the display terminal by performing complex image analysis beforehand, while still achieving the goal of clear area identification for users.
3Loss of information
If the system processes and overlays point-of-view information in real-time during playback, then users get immediate area identification, but the playback performance and speed are reduced
Solution Approach 1:
The system performs all point-of-view information extraction and processing before the wide-view image is distributed to communication terminals. By completing this complex processing in advance rather than during playback, the system ensures that area information is readily available for immediate overlay, maintaining high playback performance without real-time processing delays.

AI summary
A display terminal includes: circuitry that receives an instruction to play back a wide-view image having a wide angle of view, the wide-view image being a moving image and having been recorded for distribution to a communication terminal; and in response to the instruction to play back the wide-view image, controls a display to display a predetermined-area image representing a predetermined area of the wide-view image, based on point-of-view information for specifying the predetermined area of the wide-view image being having been distributed and displayed at the communication terminal.
