Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing communication systems, it is difficult for users to seamlessly transition between viewing wide-view images and still images of specific areas within a wide-view image, leading to challenges in understanding and navigating the content effectively.

Innovation Solution

A display terminal and information processing system that enable the playback of a predetermined-area moving image based on point-of-view information derived from a wide-view still image, allowing users to switch between still and moving images of a specific area within a wide-view image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If users view wide-view images with wide angle of view, then the imaging range is expanded to cover difficult-to-reach areas, but it becomes difficult to focus on and understand specific predetermined areas within the wide-view image

Engineering Contradiction:

Improveimaging rangeVSAvoiddetail information of specific area

Core Design Contradiction:

Area of stationary objectVSLoss of information

Solution Approach 1:

The patent segments the wide-view image into multiple predetermined areas, allowing users to focus on specific regions of interest while maintaining access to the complete wide-angle view. This segmentation enables detailed examination of particular areas without sacrificing the overall context provided by the wide imaging range.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts predetermined areas from the wide-view image to create focused views of specific regions. By taking out and displaying selected areas in detail, the system allows users to examine specific content closely while the wide-view image remains available for context.

Inventive Principle:

Principle #2Taking out (Extraction)

2Area of stationary object

If users manually navigate through wide-view images to find specific areas, then the imaging range coverage is maintained, but the operation complexity and time required increase

Engineering Contradiction:

Improveviewing coverageVSAvoidnavigation operation

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

The patent performs preliminary actions by pre-defining and marking predetermined areas within the wide-view image before user interaction. These predetermined areas are prepared in advance with associated still images and moving images, so when users want to view a specific area, the system can immediately display the relevant content without requiring manual navigation or searching.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces predetermined area information as an intermediary between the wide-view image and the detailed views. This intermediary layer contains metadata about specific areas, allowing users to quickly access detailed still and moving images of particular regions without manually navigating through the entire wide-view image.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If the system provides both wide-view images and detailed predetermined-area images, then the information completeness is improved, but the device complexity increases

Engineering Contradiction:

Improveinformation completenessVSAvoidsystem structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements a nested structure where predetermined area information is embedded within the wide-view image data structure. Still images and moving images of predetermined areas are nested within the overall wide-view image framework, allowing the system to manage multiple levels of detail without creating separate independent systems. This nesting reduces complexity by organizing related data hierarchically.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent creates a universal system that handles both wide-view images and predetermined-area detailed images through a single integrated architecture. The same display terminal and processing logic can display either the complete wide-view image or focused predetermined-area images based on user selection, eliminating the need for separate dedicated systems for each viewing mode.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display terminal includes circuitry that: receives an instruction to play back a moving image associated with a predetermined-area still image, the predetermined-area still image representing a predetermined area of a wide-view still image displayed on a display and having a wide angle of view; and in response to the instruction to play back the moving image, controls a display to display a predetermined-area moving image, based on point-of-view information indicating the predetermined area represented by the predetermined-area still image, the predetermined-area moving image representing a predetermined area of a wide-view moving image including the wide-view still image.
