Image-Audio Synchronization for Moving Object Selection on Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for outputting audio data corresponding to image data on a display screen have low directivity, making it difficult to distinguish multiple sounds and determine which image data item is moving, especially when image data items are moved.
Innovation Solution
An information processing device that detects the position change of image data items and performs image and audio processing accordingly, allowing for easier selection by correlating image and audio data item changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only sound volume and sound field adjustment is performed on audio data items, then the audio output can be generated, but the directivity is low and it is difficult to distinguish multiple sounds and determine which image data item is moving
Solution Approach 1:
The patent applies dimensionality change by introducing motion state information as an additional dimension for audio processing. Instead of only adjusting sound volume and sound field based on position, the system now processes audio data items differently based on both their spatial position and their motion state (moving vs. stationary). This creates a multi-dimensional audio output that provides directional cues about which image data item is moving, thereby improving position detection precision and making image data item selection easier.
2Device complexity
If audio data items are processed only by adjusting sound volume and sound field, then the processing is simple, but the ability to distinguish multiple sounds and identify moving image data items is poor
Solution Approach 1:
The patent applies preliminary action by detecting the motion state of image data items before performing audio processing. The system first determines which image data items are moving and which are stationary, then applies different processing strategies to audio data items based on this pre-detected motion information. This allows the system to preserve motion information in the audio output without requiring complex real-time processing during the audio generation phase.
Solution Approach 2:
The patent applies segmentation by dividing audio data items into different groups based on the motion state of their corresponding image data items. Audio data items are processed separately according to whether their associated image data item is moving or stationary, creating distinct audio processing paths. This segmentation preserves motion information while keeping each processing path relatively simple, avoiding the need for overly complex unified processing.
