Display Control Device Scaling State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for wide TVs fail to properly display images with different aspect ratios and scaling superposed images, leading to issues like letter missing and requiring manual mode selection, especially when switching between ordinary 16:9 images and scaling superposed images.
Innovation Solution
A display control device and method that includes decision and display control means to determine changes in the scaling state of moving-image portions and select appropriate screen modes based on entire aspect information, ensuring proper display by automatically adjusting screen modes in response to changes in image formats and scaling states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screen mode is selected based on image format (e.g., 16:9, 4:3) in existing display control systems, then the display can show images in their native aspect ratio, but the system fails to properly display scaling superposed images where the moving-image portion is scaled to a different aspect ratio
Solution Approach 1:
The patent changes the parameter used for screen mode selection from image format type (16:9, 4:3) to scaling state (whether the moving-image portion is scaled). The decision unit detects the scaling state of the moving-image portion and triggers screen mode reselection based on this parameter change, enabling proper display of both ordinary images and scaling superposed images
Solution Approach 2:
The system dynamically adjusts the screen mode based on the detected scaling state of the moving-image portion. When scaling state changes (e.g., from unscaled to scaled), the screen mode is automatically reselected to match the current state, making the display system adaptive to different image formats and scaling conditions
2Reliability
If manual mode selection is required to properly display different image formats, then display accuracy can be maintained, but user operation complexity increases and convenience decreases
Solution Approach 1:
The display control system performs self-service by automatically detecting the scaling state of the moving-image portion and selecting the appropriate screen mode without user intervention. The decision unit monitors scaling state changes and triggers automatic screen mode reselection, eliminating the need for manual mode selection while maintaining display accuracy
Solution Approach 2:
The system implements feedback by continuously monitoring the scaling state of the moving-image portion and using this information to automatically adjust the screen mode. The decision unit detects changes in scaling state and triggers相应的 screen mode changes, creating a closed-loop control system that maintains optimal display settings
3Device complexity
If the screen mode remains fixed based on original image format, then the initial display setup is simple, but the system cannot adapt when switching between ordinary images and scaling superposed images
Solution Approach 1:
The system transitions from a static screen mode selection (fixed based on original image format) to a dynamic selection mechanism that responds to changes in scaling state. The decision unit detects when the moving-image portion is scaled and automatically reselects the screen mode, enabling the system to adapt to different image formats without increasing overall control complexity

AI summary
A display control device for controlling the display of an image in a display device includes a decision unit configured to decide whether the state of a scaling of a moving-image portion in a display object image or an image to be displayed in the display device has changed; and a display control unit configured to select a screen mode for displaying the display object image in response to the change in the scaling state of the moving-image portion in the display object image, and to display the display object image in the screen mode in the display device.
