Portable Terminal Screen Region Extraction for Image Forming Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in easily viewing and operating application screens on image forming apparatus displays due to varying screen sizes of portable terminals, leading to intricate operations when sharing screens between portable terminals and image forming apparatuses.
Innovation Solution
An information processing system that determines the presence of an operation-receiving region on the portable terminal's screen and extracts the corresponding operating region, then displays it on the image forming apparatus in a larger format, maintaining the aspect ratio to facilitate user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the application screen from a portable terminal is displayed on the image forming apparatus display, then the user can operate the application through the image forming apparatus, but the screen elements become too small to easily view and operate due to size reduction
Solution Approach 1:
The patent divides the portable terminal screen into multiple regions: a full screen image display region and an operating region display region. The operating region (containing buttons, input fields, and interactive elements) is extracted and displayed separately in a magnified format on the image forming apparatus display, while the full screen image provides contextual background. This segmentation allows users to easily view and interact with screen elements without sacrificing the overall screen sharing functionality.
2Loss of information
If the entire application screen is displayed on the image forming apparatus, then the user can see the full context, but the operating elements become difficult to distinguish and interact with
Solution Approach 1:
The patent applies local quality by giving different display treatments to different parts of the screen. The operating region (containing interactive elements like buttons and input fields) is displayed with enhanced size and prominence in a dedicated operating region display area, while the rest of the screen content is shown at normal scale in the full screen image display region. This allows contextual information to remain visible while making operating elements easily detectable and measurable.

AI summary
An information processing system including an image forming apparatus and a portable terminal that is allowed to communicate with the image forming apparatus, includes a hardware processor that: determines whether a cooperative screen for cooperating with the image forming apparatus includes an operation-receiving region for receiving an operation by a user, the cooperative screen being displayed on a display of the portable terminal; extracts, from the cooperative screen, an image corresponding to an operating region including the operation-receiving region when the hardware processor determines that the cooperative screen includes the operation-receiving region; and displays, on a display of the image forming apparatus, the image corresponding to the operating region extracted by the hardware processor.
