Guide Map Zoom Interface for Stable Target Area Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an electronic device shakes during image enlargement, especially at high magnifications, unintended areas may be displayed, causing confusion about the intended enlarged area.
Innovation Solution
The electronic device includes a processor that displays a guide map with varying or fixed-sized guide boxes to indicate the intended enlarged area, adjusting based on detected shaking and magnification changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user manually searches for a FOD map through multiple menus, then the FOD map can be found, but the operation time is excessive and user experience deteriorates
Solution Approach 1:
The system performs preliminary action by automatically obtaining and storing FOD map information from the server before the user needs it. When the user opens the navigation app, the FOD map data is already prepared and stored in local memory, eliminating the need for manual searching and reducing access time to nearly zero.
Solution Approach 2:
The system implements self-service by automatically fetching FOD map data from the server in the background without requiring user initiation. The electronic device autonomously manages the acquisition, storage, and updating of FOD map information, freeing the user from manual operations.
2Speed
If FOD map information is stored locally in the electronic device, then access speed improves, but device memory consumption increases
Solution Approach 1:
The system applies parameter changes by dynamically adjusting the storage state of FOD map data. FOD map information is stored in memory only when needed (when the navigation app is opened or before expiration), and automatically deleted after a predetermined time period. This on-demand storage approach optimizes memory utilization while ensuring fast access when required.
Solution Approach 2:
The system implements periodic action through the expiration mechanism that automatically deletes FOD map data after a predetermined time period. This periodic cleanup ensures memory is freed for other uses while maintaining up-to-date FOD map information through periodic refreshes from the server when needed.
3Reliability
If FOD map data is frequently updated from server, then data freshness improves, but network traffic and energy consumption increase
Solution Approach 1:
The system uses periodic action by implementing an expiration time mechanism for FOD map data. Instead of frequent continuous updates, the system refreshes FOD map data only when the existing data approaches its expiration time or when explicitly triggered by user action. This periodic update strategy ensures data freshness while minimizing unnecessary network traffic and energy consumption.
Solution Approach 2:
The system applies partial action by updating FOD map data selectively rather than continuously. The update operation is triggered only when necessary (at expiration or on-demand), performing the minimum required action to maintain data reliability without excessive network communication or energy expenditure.

AI summary
Disclosed is an electronic device including a display, a camera, and a processor. The processor may be configured to display, on the display, a first image obtained through the camera, display, in response to the first image being enlarged in one magnification in a designated first magnification range, the enlarged first image as a second image, display, in a designated area of the display, a guide map including a first guide box indicating a location of the second image and having a size which varies in response to a magnification change in the first magnification range, and when the first image or the second image is enlarged to a third image in response to the first image or the second image being enlarged by one magnification in a designated second magnification range greater than the first magnification range, change the first guide box to a second guide box having a fixed size. The second guide box may indicate a location of the third image on the guide map. Various other embodiments inferred from the disclosure are also possible.
