Display Device With Guided Partial-Screen Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, such as smart TVs, lack the ability to enlarge a specific user-desired portion of an image and provide quick and easy access to the enlarged area, while also addressing the mismatch between coordinate information of video data and remote controller inputs.
Innovation Solution
A display device that allows for automatic execution of a specific area enlargement mode based on video data category, enabling a graphical user interface for quick and easy checking of enlarged areas, and synchronizing coordinate information between video data and remote controller inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen ratio adjustment function is used to enlarge full screen, then the entire screen can be enlarged, but a specific user desired portion cannot be enlarged
Solution Approach 1:
The screen is divided into a first display area showing the entire video signal and a second display area showing an enlarged partial image signal from a specific region. This segmentation allows users to view both the full screen and a magnified portion simultaneously, enabling targeted enlargement of specific areas while maintaining overall context.
2Adaptability or versatility
If picture in picture function divides display area into first and second display areas, then partial image can be displayed, but the function is complex and not automatically executed
Solution Approach 1:
The system automatically determines whether to execute the specific area enlargement mode based on category information of the video data without requiring manual user selection. The controller automatically switches between full screen display and specific area enlargement display according to the video category, simplifying user operation while maintaining display flexibility.
3Measurement precision
If manual selection of enlargement area is required, then specific area can be enlarged, but user cannot quickly check enlarged area and coordinate mismatch occurs
Solution Approach 1:
The system pre-processes video data to identify category information and automatically determines the appropriate display mode before user interaction. By preliminarily analyzing the video content and setting the enlargement parameters automatically, the system eliminates the time required for manual area selection and coordinate matching, while maintaining precise enlargement of relevant areas.
