Moving Picture Capture Section Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current moving picture reproduction systems are inconvenient for capturing moving pictures as they require users to manually set capture sections, which can be cumbersome and inaccurate, especially when trying to capture both video and audio data simultaneously.
Innovation Solution
A method and apparatus that automatically determine a moving picture feature section at a capture instruction time, allowing for the capture of both audio and video data from a moving picture stream, eliminating the need for users to manually set capture sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user manually sets capture sections by selecting start and end points, then the user can capture specific moving picture sections, but the operation becomes cumbersome and inaccurate
Solution Approach 1:
The system automatically determines capture sections by detecting feature sections in the moving picture stream without requiring user intervention for manual selection. The feature section detector identifies significant portions (video features or audio features) and the capture section determiner automatically selects capture sections based on these detected features, allowing the system to serve itself rather than requiring user expertise for accurate section selection
Solution Approach 2:
The patent replaces the mechanical manual selection process with automated detection mechanisms. Instead of requiring users to physically select start and end points through interface interactions, the system uses feature section detection algorithms that automatically identify and determine capture sections based on analyzing video and audio characteristics in the stream
2Ease of manufacture
If only still images are captured at capture moments, then the capture process is simple, but the picture quality is poor and usage is limited
Solution Approach 1:
The system transitions from capturing static still images to capturing dynamic moving picture sections. By detecting feature sections that span multiple frames and determining capture sections that include temporal duration, the system captures moving pictures that preserve motion information, making the captured content more versatile for various uses while maintaining process simplicity through automated detection
3Ease of operation
If still images are captured instead of moving pictures, then the capture process is straightforward, but audio data of the moving picture is not captured
Solution Approach 1:
The patent merges video and audio capture into a unified moving picture capture process. The feature section detector analyzes both video and audio streams, and the capture section determiner determines capture sections that include both video and audio data simultaneously. This combining approach ensures complete data capture while maintaining operational simplicity through integrated processing

AI summary
A method and an apparatus for capturing video data and audio data according to reproduction of a moving picture stream are provided. In an apparatus for reproducing the moving picture, a moving picture feature section at a capture instruction time is determined as a capture section for audio data and video data decoded from the moving picture stream when a capture instruction is input while the moving picture stream is reproduced. Next, audio data and video data corresponding to the capture section among the audio data and the video data decoded from the moving picture stream are captured.
