Dynamic Magnification Adjustment for Targeted Image Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying images on a screen, such as maps or CAD images, require numerous repetitive operations to navigate to a targeted position, often involving unnecessary magnification changes and display of irrelevant areas, making the process inefficient and time-consuming.
Innovation Solution
A method that involves setting a point of symmetry with respect to the image center, reducing magnification to identify the targeted position, and then enlarging the image using the targeted position as a center, minimizing unnecessary area display and reducing the number of operations required to reach the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image is sequentially moved without changing magnification to reach the targeted position, then the current magnification is maintained, but the number of moving operations increases and the process becomes time-consuming
Solution Approach 1:
The patent applies dynamics by making the magnification level changeable and adaptable during the navigation process. Instead of maintaining a fixed magnification, the system dynamically adjusts magnification based on the distance to the targeted position and user needs, allowing efficient navigation at low magnification followed by automatic zooming when the target is reached.
Solution Approach 2:
The patent changes the magnification parameter automatically during the navigation process. The system transitions from one magnification level to another based on the navigation progress, eliminating the need for manual magnification adjustments and reducing the time required to reach the targeted position.
2Loss of information
If the magnification is reduced to display the targeted position, then the targeted position becomes visible, but unnecessary display areas increase and the relevant area decreases
Solution Approach 1:
The patent applies local quality by making different parts of the displayed image have different importance levels. The system identifies and emphasizes the area containing the targeted position while minimizing or excluding unnecessary areas, ensuring that the display focuses on relevant information rather than uniformly showing the entire image at reduced magnification.
Solution Approach 2:
The patent segments the display area into relevant and irrelevant portions. By calculating the position of the targeted position and determining the necessary display boundaries, the system effectively segments out only the necessary area for viewing, excluding unnecessary regions from the display.
3Loss of information
If the image is moved multiple times with changing directions to find the targeted position, then the targeted position can be located, but the number of operations increases and efficiency decreases
Solution Approach 1:
The patent implements feedback by continuously monitoring the position of the displayed image relative to the targeted position and automatically adjusting the image position and magnification accordingly. This closed-loop control eliminates the need for multiple manual moving operations with direction changes, as the system autonomously navigates to the target.
Solution Approach 2:
The patent replaces the manual mechanical operation of repeatedly moving and redirecting the image with an automated computational system. The calculation unit automatically computes the necessary image position and magnification changes, substituting manual iterative adjustments with a single automated navigation process.
4Ease of manufacture
If the center of the displayed image is used as the reference for magnification change, then the magnification change is simple, but unnecessary display areas increase on the opposite side of the movement direction
Solution Approach 1:
The patent applies asymmetry by using the targeted position itself as the reference point for magnification changes rather than the center of the displayed image. This asymmetric approach ensures that the magnification change is centered on the relevant area, eliminating unnecessary display areas that would otherwise appear on the opposite side of the movement direction.

AI summary
Method, apparatus and program product for efficient display of an image at a targeted position in an image on a display screen by displaying, on the display screen, an image on which the targeted position is not displayed; setting a first position specified on the image displayed on the display screen, and a second position having a point symmetry with respect to a center of the displayed image; displaying the image while reducing a display magnification of the displayed image to a certain magnification to a degree with which the targeted position can be identified in the image, employing the second position as a center; and displaying the image while enlarging the displayed image to a certain magnification, employing the targeted position or a designated neighboring point as a center on the image obtained after the magnification change.
