Display Mode Switching That Preserves Cross-Screen Image Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smartphones fail to maintain correlation between images displayed in large and small screen modes, leading to a lack of new information provision when switching between display modes.
Innovation Solution
An information processing device that switches between display modes by generating and displaying images using first, second, and third processing, where the third image is generated based on the result of the second processing, ensuring a correlation and providing new information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display mode is switched from small screen to large screen and back to small screen, then the display area can be flexibly adjusted, but the image displayed returns to the original small screen image without correlation to the large screen content
Solution Approach 1:
The system performs preliminary action by generating and storing a third image during the second period (large screen mode) that incorporates the result of second processing. This pre-prepared image ensures that when switching back to small screen mode, the displayed content reflects the large screen processing results rather than returning to the original first image, thus maintaining information correlation across display mode transitions.
2Device complexity
If the same image is displayed before and after switching to large screen mode, then the display processing is simple, but no new information is provided to the user
Solution Approach 1:
The third image acts as an intermediary that bridges the first and second images. It incorporates processing results from the large screen mode (second processing) and presents them in a format suitable for small screen display. This intermediary image ensures that information gained during large screen viewing is preserved and reflected in subsequent small screen display, preventing information loss while maintaining manageable processing complexity.

AI summary
A display device is capable of switching between a first display mode and a second display mode, the second display mode having a larger display area than the first display mode. When the display mode is the first display mode in the first period, the display mode is the second display mode in the subsequent second period, and the display mode is the first display mode in the subsequent third period, an image generator (CCP_1) makes an image to be displayed at a start point of the third period to be different from an image displayed at an end point of the first period. In the third period, the image generator (CCP_1) uses a result of the processing in the second period.
