Mobile Terminal Screen Preview and Editing Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for setting images as background pictures on mobile communication terminals are complex and prone to errors due to the lack of a preview function, requiring users to know the display device's resolution and often necessitating external editing through a PC, which is inconvenient.
Innovation Solution
A mobile communication terminal with a display unit, screen setting information storage, a key input unit, a controller, and an image processor that allows users to preview and edit images within the terminal, enabling preview of the edited image and reducing errors by displaying a preview domain identical to the selected screen type and size, and controlling image editing based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If image editing is performed through external PC with image editor, then image editing capability is improved, but operation convenience deteriorates
Solution Approach 1:
The patent merges the image editing function with the mobile terminal itself by integrating an image editor application and processing capabilities into the terminal. This allows users to edit images directly on their mobile devices without needing to connect to external PCs, thereby maintaining advanced editing capabilities while significantly improving operation convenience.
Solution Approach 2:
The mobile terminal is equipped with built-in image editing software and processing power, enabling it to serve its own image editing needs independently. Users can perform all necessary image editing operations directly on the terminal without external assistance, making the system self-sufficient and eliminating the need for PC connectivity.
2Area of stationary object
If image is enlarged to fit display region, then display coverage is improved, but image distortion increases
Solution Approach 1:
The patent applies partial action by selectively enlarging only the necessary portions of the image that need to be displayed, rather than uniformly enlarging the entire image. The system intelligently determines which parts of the image to display and enlarges only those portions, thereby achieving full display coverage while minimizing image distortion in the displayed areas.
Solution Approach 2:
The image processing is divided into segmentation where different regions of the image are handled differently. The system segments the image into displayable and non-displayable portions, applying enlargement only to the displayable segments that fit within the screen boundaries, thus avoiding unnecessary distortion while maximizing display coverage.
3Device complexity
If preview function is not provided, then device complexity is reduced, but user error increases
Solution Approach 1:
The patent implements a preview function that displays the edited image before finalizing the editing operation. This preliminary action allows users to review their edits and make corrections if needed, significantly reducing user errors. The preview is generated and displayed within the existing interface without adding substantial complexity to the device architecture.
Solution Approach 2:
The preview function serves as a feedback mechanism, showing users the result of their editing actions before they are committed. This immediate visual feedback allows users to verify that their edits produce the desired outcome, reducing the likelihood of errors and ensuring user satisfaction without requiring complex additional hardware or systems.
4Loss of information
If image is reduced to display whole image, then image completeness is improved, but display quality deteriorates
Solution Approach 1:
The system applies partial action by selectively reducing the image size only to the extent necessary to fit the entire image within the display region. Rather than uniformly reducing the quality of the entire image, the system reduces the dimensions while maintaining the highest possible quality, and only reduces further if absolutely necessary to achieve complete display coverage.
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting the reduction ratio based on the specific image dimensions and display region characteristics. The system calculates the optimal reduction parameters that maintain the best possible image quality while ensuring the entire image is displayed, avoiding excessive quality loss by precisely controlling the reduction parameters.

AI summary
A mobile communication terminal includes a display unit for displaying an image for screen setting; a screen setting information storage unit storing screen setting information; a key input unit receiving a type of screen for the screen setting and selection information of user for an image edit command; a controller displaying a preview domain identical with the selected screen in type and size based on the selection information of the user for the type of the screen, and controlling an image edit in the preview domain based on the selection information of the user for the image edit command; and an image processor changing indication information of the display unit by control of the controller.
