3D Subtitle Processing Device Dynamic Audio-Driven Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D image reproduction devices do not effectively change the display state of subtitles, such as color, transparency, or position in response to changes in the volume of the accompanying main image, limiting the immersive 3D experience.
Innovation Solution
An image processing device that includes a video decoder, subtitle decoder, superimposition unit, audio decoder, and display unit, which modifies subtitle data based on audio volume levels to create combined left-eye and right-eye display patterns, changing the color, transparency, and position of subtitles to enhance the 3D effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If subtitle data is superimposed on the main image without modification, then the subtitle display is simple and stable, but the visual impact and user engagement are limited
Solution Approach 1:
The patent applies dynamics by making subtitle display parameters (position, transparency, color) variable rather than fixed. The subtitle display position changes dynamically based on audio volume levels, transparency adjusts according to sound intensity, and color shifts respond to audio characteristics, creating an engaging dynamic visual experience that adapts to the content being played
Solution Approach 2:
The patent implements parameter changes by modifying multiple subtitle display parameters simultaneously - position coordinates (x, y), transparency levels, and color values - based on audio analysis results. These parameter changes enable subtitles to respond to audio volume and characteristics, enhancing visual impact while maintaining readability
2Productivity
If subtitle display parameters are modified to enhance 3D effect, then user engagement increases, but the processing complexity and computational load increase
Solution Approach 1:
The system performs self-service by automatically analyzing audio characteristics and autonomously adjusting subtitle display parameters without requiring manual intervention. The audio analysis unit processes sound data and the control unit automatically modifies subtitle parameters based on the analysis results, enabling the system to enhance itself independently
Solution Approach 2:
The patent implements feedback by using audio analysis results to continuously adjust subtitle display parameters in real-time. The system analyzes audio volume and characteristics, then feeds this information back to modify subtitle position, transparency, and color, creating a closed-loop system that responds dynamically to content changes
3Reliability
If subtitles are displayed with fixed position and transparency, then readability is maintained, but the immersive 3D experience is reduced
Solution Approach 1:
The patent applies dynamics by making subtitle display parameters (position, transparency, color) variable rather than fixed. The subtitle display position changes dynamically based on audio volume levels, transparency adjusts according to sound intensity, and color shifts respond to audio characteristics, creating an engaging dynamic visual experience that adapts to the content being played
Solution Approach 2:
The patent applies local quality by making different parts of the subtitle display have different properties based on audio characteristics. Specifically, the transparency of subtitles varies locally according to audio volume, allowing subtitles to appear more opaque during quiet passages and more transparent during loud passages, thereby maintaining readability while enhancing immersion

AI summary
A processing device for adding a subtitle to a three-dimensional (3D) image produced by left-eye and right-eye display patterns displayed on a display is disclosed. The processing device may include a video decoder configured to receive video content data representing content left-eye and content right-eye display patterns. The processing device may also include an audio decoder configured to receive sound data indicative of an audio volume level. Additionally, the processing device may include a subtitle decoder configured to receive subtitle data indicative of a subtitle display pattern, and modify the subtitle data based on the sound data. The processing device may also include a superimposition unit configured to combine the modified subtitle data with the video content data to create combined pattern data representing combined left-eye and combined right-eye display patterns.
