Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for analyzing images in portable electronic devices are hindered by long processing times due to the complexity of computing processes and the need to store extensive image information, making it difficult to determine whether data is video or audio and to apply effects automatically.
Innovation Solution
An electronic device and method that temporarily stores audiovisual data, analyzes the audio signal dynamically, selects appropriate sound effects, and applies these effects during playback, utilizing a processor to control the analysis and application of modes based on the audio signal characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image analysis methods are used with extensive learning processes and image information storage, then analysis capability is improved, but processing time increases and device complexity increases
Solution Approach 1:
The patent extracts only the necessary audio signal features from the media file instead of performing comprehensive image analysis. By focusing specifically on audio characteristics relevant to sound effect selection, the system avoids the computational burden of analyzing entire images or video frames, thus reducing processing time while maintaining adequate analysis capability for the specific task.
Solution Approach 2:
The patent segments the media processing task into distinct stages: audio signal extraction, audio characteristic analysis, and sound effect selection. This segmentation allows the system to process only the relevant audio portion of the media file rather than analyzing all image and audio data, significantly reducing processing time while preserving the necessary analysis functionality.
2Measurement precision
If comprehensive image information is stored for analysis, then analysis accuracy is improved, but memory requirements and device complexity increase
Solution Approach 1:
The patent extracts only the essential audio signal data from the media file, storing and processing merely what is necessary for sound effect analysis. This extraction approach eliminates the need to store comprehensive image information, reducing memory requirements and device complexity while maintaining sufficient accuracy for selecting appropriate sound effects based on audio characteristics.
3Measurement precision
If dynamic audio signal analysis is performed during playback, then sound effect selection accuracy is improved, but processing load increases
Solution Approach 1:
The patent performs partial analysis by focusing only on specific audio signal characteristics that are relevant to sound effect selection, rather than conducting a complete analysis of all audio parameters. This partial action approach maintains adequate selection accuracy while significantly reducing the processing load during playback operations.

AI summary
The present disclosure provides an electronic device and method for playing image data. The method for playing back image data in an electronic device includes storing an audiovisual (A/V) data for a predetermined period of time in a memory of the electronic device. The electronic device plays back the A/V data, wherein upon playing back, by the electronic device, the A/V data comprises analyzing an audio signal of the A/V data dynamically to select one of a plurality of sound effects based on the analyzed audio signal. The A/V data is played back by applying the selected sound effect to at least a part of the A/V signal.
