Dynamic Display Scaling for Accurate Image Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multifunctional digital image forming apparatuses face difficulties in perceiving and editing images due to small, low-resolution touch-screen displays, which hinder accurate dragging and dropping of images, especially with complex layouts or patterns, as they can only see a part of the image at a time.
Innovation Solution
A display control device and method that dynamically adjusts the display to show a larger area of the first image by reducing its size when a second image is dragged a certain distance, allowing users to obtain a full view and accurately place the second image at a desired position without needing to constantly scroll or reduce the image manually.

1Length of moving object
If the display screen size is kept small for portability, then the device is more portable, but users cannot see the full image layout and have difficulty in accurate image placement
Solution Approach 1:
The patent introduces a temporal dimension to the display by dynamically changing the displayed content based on drag distance. Instead of trying to show all images simultaneously on a small screen, the system transitions between different display states (full view vs. detailed view) as the user drags images, effectively using time to resolve the spatial limitation of the small screen.
Solution Approach 2:
The display content is made dynamic rather than static. The system automatically adjusts what is displayed on the screen based on the real-time drag distance of images. When drag distance exceeds a threshold, the display switches from showing the full layout to showing detailed information, allowing the same small screen to serve multiple functions throughout the editing process.
2Loss of information
If users manually reduce the image to see the full layout, then they can perceive the complete image, but they need to devote extra time to create a reduced version
Solution Approach 1:
The system performs the image reduction operation automatically without requiring user intervention. When the drag distance exceeds the threshold, the control device automatically generates and displays a reduced version of the first image, eliminating the need for users to manually create reduced versions and saving their time.
Solution Approach 2:
The system prepares the reduced version of the image in advance by automatically generating it when needed during the drag operation. This preliminary action of automatic image reduction ensures that the full layout is immediately visible when required, without requiring users to spend time on manual preparation.
3Measurement precision
If the display shows only a part of the image at a time, then the screen can display detailed content, but users cannot perceive the full view and have difficulty in accurate dragging
Solution Approach 1:
The display dynamically switches between showing the full image layout and showing detailed content based on the drag operation progress. When drag distance is small, the display shows the full layout to provide spatial context. When drag distance exceeds the threshold, it transitions to showing detailed content or reduced views, allowing the high-resolution screen to serve both overview and detail needs at different times.

AI summary
A display control device comprises: a display; a movement judgment portion that judges whether or not a second image moves a certain distance by user dragging the second image to an arbitrary position of a first image on the display, a controller that allows the display to show a larger area of the first image at least by reducing the first image in size, if the movement judgment portion judges that the second image moves a certain distance; and an image giving portion that gives the second image to a user desired position on the first image by user dropping the second image at the position.
