Portable Terminal Application Installation via Screen Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable terminals face a cumbersome process when trying to install applications from another device, as they need to access a separate application server and search for the desired application by name, which is inefficient with increasing numbers of available applications.
Innovation Solution
A method that allows users to acquire a screen image from another portable terminal, extract application information, display a list of applications, request and receive an installation file for selected applications, and install them directly using the received file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users access a separate application server and search for applications by name, then they can install applications, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent uses camera imaging to capture the application icon from another terminal's screen, creating a visual copy of the target application. This copied visual information is then processed to extract application details and initiate installation, replacing the traditional text-based search method and significantly simplifying the operation process
Solution Approach 2:
The system introduces an image processing intermediary that acts as a bridge between the user's visual observation of another terminal's screen and the application installation system. The image processing module extracts application information from the captured screen image and translates it into installable data, mediating between visual input and system execution
2Reliability
If users access a separate application server and search for applications, then they can find and install applications, but the process takes excessive time
Solution Approach 1:
The system performs preliminary actions by capturing the application icon image in advance through camera imaging. The image is then pre-processed to extract application information before the actual installation is initiated. This preliminary extraction and preparation of application data eliminates the need for time-consuming server searches and direct installation steps
3Adaptability or versatility
If the number of application icons increases in portable terminals, then more functions are available, but the display screen becomes cluttered and harder to manage
Solution Approach 1:
The patent transitions the application selection process from the two-dimensional display screen to the three-dimensional visual space captured by the camera. By imaging the other terminal's screen through the camera, users can view and select applications in an external visual dimension, effectively bypassing the limited screen real estate and cluttered icon arrangement

AI summary
A method for installing an application in a portable terminal includes acquiring a screen image of another portable terminal and acquiring information about at least one applications from the acquired screen image, displaying a list of the at least one applications whose information is acquired, and requesting and receiving an installation file of an application selected by a user from the displayed list, and installing the selected application by using the received installation file.
