External Display Screen Resizing for Aspect-Ratio Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen display technologies on external terminal devices may result in poorly visible images due to alterations in vertical and horizontal widths, leading to reduced visibility.
Innovation Solution
An information processing device adjusts screen data based on the vertical and horizontal dimensions of the external display unit, generating and transmitting screen data that maintain image visibility by accounting for alterations in these dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the external terminal device reconstructs the screen image to accommodate changes in display unit dimensions, then the screen can be displayed on the external display unit, but the screen image becomes stretched and visibility deteriorates
Solution Approach 1:
The information processing device performs preliminary actions by generating alternative screen data in advance that is pre-adjusted for different display unit dimensions. When dimension changes occur, the device transmits the pre-generated alternative screen data that maintains proper aspect ratio and visibility, preventing the need for post-hoc reconstruction that would cause stretching.
Solution Approach 2:
The system changes the parameter of screen data generation by creating multiple versions of screen data with different dimensional parameters. Instead of transmitting a single screen data set that may not match the current display unit dimensions, the system generates and transmits alternative screen data with adjusted parameters to match the actual display dimensions, thereby maintaining image quality.
2Ease of operation
If the external terminal device transmits screen data to the information processing device, then the screen can be displayed on the external display unit, but the screen image may be stretched when dimension alterations occur
Solution Approach 1:
The system implements feedback by having the external terminal device transmit information about the display unit's vertical and horizontal widths to the information processing device. The information processing device uses this feedback information to generate appropriate alternative screen data that matches the current display dimensions, ensuring the screen image is not stretched while maintaining proper aspect ratio.
Solution Approach 2:
The information processing device performs preliminary generation of alternative screen data based on the received display unit dimension information. This pre-adjusted screen data is then transmitted to the external terminal device, which displays it without needing to perform reconstructive operations that would cause stretching.

AI summary
An information processing device receives information on a vertical and horizontal width of an external display unit, and generates screen data on a screen image to be displayed on the external display unit. When an event requiring an alteration in the vertical width and/or the horizontal width occurs, the information processing device transmits screen data including: screen data on a first content obtained by altering the screen displayed on the external display unit at that time to a size corresponding to an altered vertical and horizontal width; and screen data on a second content to an external terminal device. The second content, generated in the external display unit, is displayed in a region due to a difference between a pre-altered vertical width and the corresponding post-altered vertical width displayed on the external display unit, and between a pre-altered horizontal width and the post-altered horizontal width of the external display unit.
