Multi-Display Magnification Control via Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for displaying images on multiple devices, such as those described in JP-A-2008-008917, are limited to showing the same image on two displays in the same manner, lacking flexibility in magnification and scrolling capabilities, which hinders user convenience when viewing the same image data on separate screens.
Innovation Solution
A system comprising a first and second display, along with a controller that allows the first display to show an image with a first magnification and the second display to show either the same image with the first magnification or a partial image with a higher second magnification, enabling selective magnification and scrolling of specific image portions, while detecting user motion and holding to manage display positions and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the same image is displayed on two displays in the same manner, then display consistency is maintained, but flexibility in magnification and scrolling is limited
Solution Approach 1:
The patent implements dynamic display control where the second display can switch between displaying the full image at first magnification and a partial magnified image at second magnification. The controller dynamically adjusts display parameters based on user interaction, allowing the magnification level to change from a first level to a second level greater than the first, thereby providing adaptability without requiring multiple fixed display modes
Solution Approach 2:
The patent segments the image display function across two displays, with the first display showing the full image and the second display showing either the full image or a magnified portion. This segmentation allows independent control of each display, enabling the second display to provide detailed views of specific regions while the first display maintains the overall context, thus achieving magnification flexibility through functional division
2Measurement precision
If a partial image with higher magnification is displayed on the second display, then detailed viewing of specific image parts is enabled, but the ability to view the broader image context is reduced
Solution Approach 1:
The first display acts as an intermediary that maintains the full image context while the second display provides magnified views of specific portions. The controller coordinates between the two displays, allowing the user to view detailed information on the second display while the first display preserves the overall image context, thus the intermediary display compensates for the context loss in the magnified view
Solution Approach 2:
The patent adds a spatial dimension to the display system by using two separate displays positioned in different locations. The first display provides the global view while the second display provides local detailed views, effectively using the spatial arrangement of multiple displays to simultaneously present both overall context and detailed information that would be mutually exclusive on a single display
3Ease of operation
If motion detection is used to control display position, then user interaction convenience is improved, but unintended motion may cause unwanted display changes
Solution Approach 1:
The patent inverts the typical motion detection approach by using the absence or type of holding detection to gate the response to motion. Instead of responding to all motion, the system only responds to motion when proper holding is detected, effectively inverting the control logic from motion-triggered to holding-validated motion-triggered, thereby preventing unintended activation while maintaining ease of operation

AI summary
An information-processing system causes an image to be displayed in display region 101 of a first display and in display region 241 of a second display in either of a first operation mode, in which images Im11 and Im12 are displayed, or a second operation mode, in which image Im11 is displayed in display region 101 and partial image Im12a is displayed in display region 241. Partial image Im12a is obtained by magnifying and displaying a part of image Im12. A user can switch the operation mode by a predetermined operation or in accordance with a setting determined in advance.
