Video Processing Apparatus Optimizing Display Size for Low-Resolution Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When low-resolution videos are displayed on high-definition display apparatuses, they often appear small and blurry due to image quality degradation from magnification, making it difficult to maintain viewer visibility.
Innovation Solution
A video processing apparatus that determines the optimal display size based on image quality information, using a scaler unit to adjust the video signal and output it to a display apparatus, while minimizing image quality degradation by considering resolution, bit rate, and encoding format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If low-resolution video is magnified to full screen size, then the display area is increased, but the image quality deteriorates due to pixel interpolation processing
Solution Approach 1:
The patent changes the display parameters (display size, resolution, aspect ratio) based on the input video's resolution characteristics. By dynamically adjusting these parameters, the system optimizes the balance between display area and image quality, avoiding excessive magnification that would cause quality degradation while still maximizing the usable display area.
Solution Approach 2:
The patent implements dynamic adjustment of video display parameters based on real-time analysis of the input video signal's resolution. The display size and configuration are not fixed but are dynamically changed according to the source video characteristics, allowing the system to adapt optimally between full-screen display and image quality preservation.
2Manufacturing precision
If low-resolution video is displayed at original size, then the image quality is preserved, but the display area becomes too small for satisfactory visibility
Solution Approach 1:
The patent adjusts display parameters such as display size, resolution, and aspect ratio based on the input video resolution. This allows the system to expand the display area while maintaining appropriate image quality by selecting optimal display configurations rather than simply magnifying the video.
Solution Approach 2:
The patent utilizes additional display dimensions and configurations (different aspect ratios, resolutions, and display modes) to increase the effective display area without directly magnifying the video content, thereby avoiding quality degradation while improving visibility.
3Area of stationary object
If video is magnified using predetermined display mode, then the display area is maximized, but the visibility is lowered due to image quality degradation
Solution Approach 1:
The patent dynamically changes display parameters (size, resolution, aspect ratio) based on the input video's resolution characteristics. This ensures that the display area is maximized only when it does not compromise visibility, maintaining an optimal balance between the two factors.
Solution Approach 2:
The patent uses feedback from the input video signal analysis (resolution detection) to adjust the display parameters. By continuously monitoring the source video characteristics and adjusting the display configuration accordingly, the system maintains visibility quality while maximizing display area.

AI summary
A video processing apparatus uses information related to an image quality of an inputted video signal which is to be displayed on a display apparatus and a determination table in which video display sizes previously set in accordance with video resolution or bit rate are held to determine an optimal size for displaying the inputted video signal.
