Solution Overview

Problem

Existing display methods and information processing apparatuses do not effectively allow users to easily recognize whether the volume of sound is appropriate, leading to potential issues such as sound cracking or missing small sounds during video capturing.

Innovation Solution

A display method and information processing apparatus that includes a first acquisition step to generate second sound data with a higher bit depth from first sound data, and an output step to display a volume video representing the volume of the second sound data, allowing users to visualize and adjust the volume levels effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If volume display is not provided, then device complexity is reduced, but users cannot easily recognize whether volume is appropriate

Engineering Contradiction:
ImproveVolume recognitionVSAvoidDisplay system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A volume video is introduced as an intermediary visual element that mediates between the audio signal and the user. The volume video converts invisible audio volume information into visible form, allowing users to recognize volume levels without adding complex control interfaces. The volume video is generated by processing sound data and mapping volume characteristics to visual representations that can be displayed on the display device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If bit depth is increased to improve sound quality, then manufacturing precision is improved, but loss of information is reduced

Engineering Contradiction:
ImproveSound data precisionVSAvoidSound information
Core Design Contradiction:
Manufacturing precisionVSLoss of information

Solution Approach 1:

The system performs preliminary conversion of sound data to floating point format with increased bit depth (e.g., 32-bit) before final processing and storage. This preliminary action preserves maximum information during intermediate processing stages, allowing for accurate volume calculations and preventing information loss that would occur with lower bit depths. The high-precision data is then appropriately processed to generate volume video while maintaining quality.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If volume video is displayed, then ease of operation is improved, but loss of time is increased due to additional processing

Engineering Contradiction:
ImproveVolume adjustmentVSAvoidProcessing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The volume video generation process operates continuously alongside the main audio processing pipeline rather than as a separate post-processing step. Volume information is extracted and converted to visual form in real-time as audio data flows through the system, ensuring that the volume display is always current without requiring additional processing time after the fact. This continuous operation maintains both responsiveness and efficiency.

Inventive Principle:
Principle #20Continuity of useful action
