Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing picture processing technologies lose attribute information about scenes in moving picture data when transferring data between different apparatuses, making it difficult to efficiently navigate and reproduce specific scenes.

Innovation Solution

A picture processing apparatus and method that detects attribute information, creates index data, and integrates it with moving picture data as stream data, ensuring that index data is stored and retained even after data transfer, allowing for efficient scene navigation and reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If independent management information files are used to store scene information, then scene indexing capability is improved, but data reliability deteriorates due to file loss during transfer

Engineering Contradiction:

Improvescene indexing capabilityVSAvoiddata retention during transfer

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent merges the management information file containing scene attribute information with the moving picture data stream, creating an integrated stream data structure. This combination ensures that when moving picture data is transferred, the scene indexing information travels with it, eliminating the file loss problem while maintaining scene navigation capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary detection of attribute information (such as face detection results) during the image acquisition phase and stores this information in advance within the stream data structure. This preliminary action ensures that scene indexing data is already prepared and embedded before transfer occurs, eliminating the need for separate management files.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If thumbnails are created from different parts of moving picture data, then scene navigation is improved, but data volume increases

Engineering Contradiction:

Improvescene navigationVSAvoiddata volume

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential attribute information (such as face detection results, scene identifiers, and position data) from the moving picture data, rather than storing complete thumbnails. This extraction approach provides sufficient scene navigation capability while significantly reducing the additional data volume compared to full thumbnail storage.

Inventive Principle:

Principle #2Taking out (Extraction)
