Solution Overview

Problem

Existing technologies do not allow users to directly interact with camera motion to operate a preview of content on a preview screen, limiting operability in grasping the substance of video sequences.

Innovation Solution

An information processing apparatus and method that extracts feature amounts containing camera motion information and displays a GUI corresponding to camera motion operations, enabling users to switch camera angles or zoom in/out, improving content previewing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If camera motion information is extracted and GUI is displayed for content preview, then user operability is improved, but device complexity increases

Engineering Contradiction:

Improveuser operabilityVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system segments the video content analysis into distinct feature extraction modules, separating camera motion detection from other video analysis tasks. This modular approach allows the complex functionality to be divided into manageable components, improving ease of operation while controlling device complexity through organized functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A graphical user interface (GUI) acts as an intermediary between the user and the complex video analysis system. The GUI translates complex camera motion data into intuitive visual representations and controls, allowing users to interact with video content without needing to understand the underlying complex processing mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If camera motion recognition is implemented for content indexing, then content grasping capability is improved, but processing time increases

Engineering Contradiction:

Improvecontent grasping capabilityVSAvoidprocessing time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary extraction of camera motion information during video encoding or pre-processing stages. By preparing and storing camera motion feature data in advance, the system enables rapid content indexing and retrieval during actual use, reducing processing time while maintaining comprehensive content grasping capability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces traditional frame-by-frame mechanical analysis with automated feature extraction algorithms that detect camera motion patterns efficiently. This substitution of automated computational methods for manual or sequential processing significantly reduces processing time while improving the accuracy of content grasping.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
