Mobile Terminal Geotagging with Location Module Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of large numbers of captured images on mobile terminals is challenging due to the difficulty in organizing and geotagging them with location information, especially when acquiring location data is ongoing.
Innovation Solution
A mobile terminal with a camera and a location information module, where the controller automatically drives the location information module when the camera is activated, allowing users to choose whether to wait for location data acquisition before capturing images, and optionally tags this information to the images or stores them without it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the location information module is automatically driven when the camera is activated, then the geotagging of images is improved, but the time required for image capture is increased due to location information acquisition
Solution Approach 1:
The location information module is driven in advance before image capture to acquire location data. The controller checks whether location information has been acquired before allowing image capture, ensuring that location data is ready beforehand rather than during the capture process, thus avoiding time delay.
Solution Approach 2:
The system dynamically adjusts the image capture process based on the acquisition status of location information. The controller displays different messages and waits for user input depending on whether location information is available, making the capture process flexible and adaptive to the current state of location data acquisition.
2Manufacturing precision
If the controller waits for location information acquisition completion before capturing images, then the geotagging quality is improved, but the user convenience is reduced due to extended waiting time
Solution Approach 1:
The location information module is driven in advance before image capture to acquire location data. The controller checks whether location information has been acquired before allowing image capture, ensuring that location data is ready beforehand rather than during the capture process, thus avoiding time delay.
Solution Approach 2:
The controller provides feedback to the user through displayed messages indicating the status of location information acquisition. When location information is not yet acquired, the controller displays a message asking the user to wait or proceed without location data, allowing users to make informed decisions based on real-time system status.
3Adaptability or versatility
If the controller displays messages requesting user input when location information is not acquired, then the user control over the process is improved, but the device complexity is increased due to additional message display and user interaction handling
Solution Approach 1:
The controller's functionality is segmented into distinct modules: one for driving the location information module, another for capturing images, and a third for handling user interactions and displaying messages. This segmentation allows each module to perform its specific function independently, reducing overall system complexity while maintaining user control flexibility.
Solution Approach 2:
The system provides self-service by automatically driving the location information module when the camera is activated and automatically checking the acquisition status. The controller handles user interactions and message display autonomously based on the current state, reducing the need for complex external control mechanisms.

AI summary
A mobile terminal (100) and its geotagging method are disclosed. When a camera function of the mobile terminal is selected, a camera (121) and a location information module (115) are driven , and an indicator (401) indicating whether or not location information has been acquired by the location information module is displayed. When an image capturing command is input, the captured image data is geotagged according to whether or not the location information has been acquired.
