Adaptive Image Display for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminal devices, such as mobile phones, are limited in displaying images and information in a manner that is suitable for different use modes, including screen direction changes and input operation methods, as they typically only show thumbnail lists or file names and title information without adapting to these changes.
Innovation Solution
A portable terminal device equipped with a use mode change detecting unit and a display method changing unit that adapts the image and information display based on detected changes in use mode, allowing for multiple input operation methods and screen orientations, such as touch panel and keypad usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the portable terminal device displays only typical information such as thumbnail lists or file names based on user setting, then the display method is simple and easy to implement, but the display is not suitable for different use modes such as screen direction changes or input operation method changes
Solution Approach 1:
The patent implements dynamic display adaptation by detecting use mode changes (screen direction, input method) and automatically adjusting the display method accordingly. The display control unit dynamically switches between different display methods based on detected use mode, making the system adaptive rather than static.
Solution Approach 2:
The patent employs feedback mechanisms where the display control unit detects use mode changes and uses this information to adjust the display method. The detection unit provides feedback about the current use mode, which the display control unit uses to select the appropriate display method, creating a closed-loop adaptive system.
2Ease of operation
If the portable terminal device changes display method according to screen direction and input operation method, then the display suitability for different use modes is improved, but the device complexity increases due to additional detecting and changing means
Solution Approach 1:
The display control unit serves multiple functions: it detects use mode changes, determines appropriate display methods, and controls the display output. By making this single component multi-functional, the patent avoids adding separate dedicated components for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent combines the detection function and display control function into an integrated display control unit. Rather than having separate detection hardware and control logic, the system merges these functions, reducing the number of discrete components and simplifying the overall device structure.

AI summary
Provided are a portable terminal device, an image display method used for same and a recording medium to record a program for same that enable display of images suitable for various forms of use, such as when the screen orientation or input operation is changed, and display of information pertaining to the images. The portable terminal device can make changes for multiple forms of use and has detection means for detecting a change in the form of use, and changing means for changing the method to be used to display image-related information on a display screen according to the detection result by the detection means.
