Source Sink Image Quality Data Transmission for Display Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses do not perform an image quality improvement process considering various image quality-related parameters, limiting the output image quality to be close to the original.
Innovation Solution
A source device transmits image quality-related data for upcoming scenes to a sink device, allowing the sink device to perform an image quality improvement process using this data, which includes receiving, storing, and applying the data during output to enhance image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display apparatuses do not perform image quality improvement process, then device complexity is reduced, but image quality is limited and cannot reach original quality
Solution Approach 1:
The source device performs preliminary actions by extracting and transmitting image quality related data (such as brightness, contrast, color information) before the actual image display. This allows the sink device to have the necessary data ready for quality improvement without requiring complex real-time analysis capabilities.
Solution Approach 2:
Image quality related data acts as an intermediary between the source content and the display output. This mediator carries essential quality parameters that enable the sink device to perform improvement processes without needing to reconstruct or analyze the original source material, thus reducing processing complexity while maintaining image quality.
2Manufacturing precision
If image quality related data is transmitted for next scene, then image quality improvement is enabled, but data transmission and processing time increases
Solution Approach 1:
The system transmits image quality related data for the next scene in advance during the current scene's display. This preliminary transmission ensures that when the next scene begins, the quality improvement data is already available, eliminating processing delays and maintaining real-time display performance.
Solution Approach 2:
The transmission of image quality related data occurs continuously and overlap with scene playback. While the current scene is being displayed, the system simultaneously prepares and transmits quality data for the upcoming scene, ensuring continuous useful action without interrupting the display flow or causing time loss.
3Manufacturing precision
If image quality improvement process is performed, then output image quality approaches original quality, but device complexity and processing requirements increase
Solution Approach 1:
The patent uses image quality related data as an intermediary that carries essential parameters (brightness, contrast, color statistics) from the source to the sink device. This mediator enables the quality improvement process by providing necessary reference information without requiring the sink device to handle complex original source material, thus reducing processing complexity while achieving near-original image quality.
Solution Approach 2:
The image quality improvement process works by adjusting display parameters (brightness, contrast, color saturation) based on transmitted quality related data. Rather than performing complex full-image processing, the system modifies key parameters to match the original quality characteristics, achieving high output quality with reduced processing complexity.
