Solution Overview

Problem

Existing technologies face challenges in efficiently displaying slow-motion images without causing delays in reproduction position, leading to increased time requirements and difficulty in understanding the video progression when slow-motion images are displayed in parallel with standard-speed images.

Innovation Solution

An information processing device that assigns different time ranges to multiple slow-motion display areas and generates corresponding slow-motion data to simultaneously display these images in parallel, allowing for synchronized viewing with standard-speed images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a slow-motion image is reproduced at a scale factor of 1/M, then the reproduction speed is reduced to allow detailed observation, but the time required to understand the video increases M times compared to standard speed reproduction

Engineering Contradiction:
Improvereproduction speedVSAvoidtime required to understand video
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent divides the slow-motion reproduction into multiple parallel display areas, each showing different time segments of the same video content. By segmenting the time range and displaying multiple segments simultaneously at different positions, the system allows viewers to observe detailed slow-motion content without having to wait through the entire extended reproduction time, thus reducing the effective time required to understand the video progression.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If slow-motion reproduction is performed simultaneously with standard-speed reproduction in parallel, then both can be viewed together, but the progress of slow-motion reproduction is cumulatively delayed and cannot keep up with standard-speed reproduction

Engineering Contradiction:
Improveparallel display capabilityVSAvoidreproduction position delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces a spatial dimension to resolve the temporal conflict between slow-motion and standard-speed reproduction. By displaying slow-motion segments at different vertical positions (different dimensions) on the screen simultaneously, the system allows both reproduction types to progress without cumulative delay. Each display area operates independently in its own temporal space while being visually integrated through spatial arrangement, enabling parallel viewing without synchronization problems.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Area of stationary object

If the whole time of reference video is covered with slow-motion reproduction at 1/M scale factor, then complete coverage is achieved, but the reproduction time becomes M times longer than standard speed

Engineering Contradiction:
Improvetime range coverageVSAvoidreproduction duration
Core Design Contradiction:
Area of stationary objectVSDuration of action of moving object

Solution Approach 1:

The patent segments the time range of the reference video into multiple sections and displays different segments in parallel across multiple display areas. Each segment covers a specific time portion of the original video, and by showing multiple segments simultaneously, the system achieves complete time range coverage while significantly reducing the total reproduction duration from M times the original to approximately the original duration plus overhead.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent maintains continuous playback across all display areas, with each area continuously advancing through its assigned time segment. This continuous parallel playback eliminates the need to sequentially watch each segment, allowing viewers to observe the entire time range of the reference video in a condensed timeframe while maintaining the detailed slow-motion observation benefit.

Inventive Principle:
Principle #20Continuity of useful action
