Video Sound Source Directional Control via Audio Manipulation Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When recording videos, the capture of ambient noise leads to cluttered sound and reduced user experience due to the recording of all sounds in the environment, which is not desirable in video mode.
Innovation Solution
An information processing method and electronic device that acquires video images and sounds in real-time, maps an audio manipulation area to adjust sound collection effects, allowing users to selectively enhance or suppress sound sources within the acquisition area of the camera group, thereby improving sound quality during video recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all sound in the environment is recorded during video recording, then the completeness of sound capture is improved, but the noise level increases and user experience deteriorates
Solution Approach 1:
The patent segments the sound field into multiple directional zones corresponding to different sound sources. The audio manipulation area is divided into multiple operation response areas, each corresponding to a specific sound source direction. This allows selective adjustment of sound collection effects for different directions, enabling the system to capture desired sounds while suppressing unwanted noise from other directions.
Solution Approach 2:
The patent applies local quality by allowing different sound collection characteristics for different spatial zones. Each operation response area in the audio manipulation area corresponds to a specific directional zone, enabling independent control of sound collection effects for each zone. This ensures that sound sources in specific directions are enhanced while noise from other directions is suppressed, improving overall sound quality without losing completeness.
2Manufacturing precision
If sound collection effect is adjusted for different sound sources, then sound quality is improved, but system complexity increases
Solution Approach 1:
The patent introduces an audio manipulation area as an intermediary interface between the user and the complex sound processing system. This visual interface maps sound source directions to selectable areas on the display screen, allowing users to control sound collection effects without dealing with complex technical parameters. The system automatically processes the selected direction and adjusts the sound collection effect accordingly, simplifying user interaction while maintaining high sound quality control capability.
Solution Approach 2:
The patent replaces complex mechanical or manual sound adjustment mechanisms with a software-based audio manipulation interface. Instead of requiring physical adjustment of microphone positions or complex manual sound mixing, the system uses a displayed audio manipulation area that responds to user selections through software processing. This substitution significantly reduces system complexity while maintaining precise sound quality control.

AI summary
An information processing method includes, in response to determining that an application is in a video mode, acquiring a video image in real time through a camera group of an electronic device and acquiring a video sound in real time through a microphone group of the electronic device; displaying the video image; mapping an audio manipulation area that includes an operation response area of a sound source in an acquisition area of the camera group; obtaining an input operation for the operation response area; and, in response to the input operation, adjusting a sound collection effect of the sound source corresponding to the operation response area.
