Display Control Circuit for Region-Specific Audio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices cannot provide appropriate audio performance that corresponds to changes in image data, often providing a single piece of input sound information for one image or relying on previously stored sound information.
Innovation Solution
A display control circuit that includes an image analysis circuit to analyze features of each region of an input image, a sound analysis circuit to analyze input sound in the frequency and time domains, a multi-sound generation circuit to generate multi-sound information matching the image features, and a sound control circuit to individually control sound for each area of the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single piece of input sound information is provided for one input image, then the device complexity is reduced, but the audio performance adaptability deteriorates
Solution Approach 1:
The patent segments the audio output into multiple independent sound channels corresponding to different regions or objects in the image. Each region can have its own sound information processed and reproduced independently, enabling region-specific audio control without requiring a completely separate audio processing system for each region.
Solution Approach 2:
The patent implements dynamic audio adaptation where sound information is automatically adjusted based on real-time image analysis. The system dynamically selects, generates, or mixes sound information corresponding to detected objects or regions in the image, allowing the audio output to change adaptively as the image content changes without manual intervention.
2Speed
If previously stored sound information is provided, then the device complexity is reduced, but the real-time audio responsiveness deteriorates
Solution Approach 1:
The patent employs preliminary action by pre-processing and storing multiple types of sound information (e.g., sound effects, ambient sounds, dialogue tracks) that can be quickly retrieved and applied when needed. The system prepares sound libraries in advance so that when image content changes, the corresponding sound information can be immediately selected and reproduced without complex real-time generation.
Solution Approach 2:
The patent implements feedback mechanisms where the audio processing system continuously monitors image input and adjusts sound reproduction accordingly. When objects or regions are detected in the image, the system receives feedback about the current visual content and automatically selects or generates appropriate sound information, creating a closed-loop system that responds in real-time to changing conditions.
3Adaptability or versatility
If multi-sound information is generated by matching object sound information to image features, then the audio performance is improved, but the processing time increases
Solution Approach 1:
The patent applies local quality by processing and generating sound information specifically for identified regions or objects within the image rather than treating the entire image uniformly. The system analyzes image features to determine which regions require attention and generates or selects sound information locally for those specific areas, improving stereophonic capability while minimizing unnecessary processing time for regions that don't require audio attention.
