Display Control Apparatus for Satellite Positioning Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems that record positional information with images lack accuracy verification, relying solely on the presence or absence of information without assessing its reliability, which can lead to incorrect data due to environmental and satellite system limitations.
Innovation Solution
A display control apparatus that determines the type of satellite used for positional information and displays this information, allowing users to estimate the accuracy and reliability of the photographing position by recognizing the satellite types and methods used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only the presence or absence of positional information is determined, then the determination process is simple, but the accuracy and reliability of the positional information cannot be assessed
Solution Approach 1:
The determination process is segmented into multiple levels: first determining whether positional information exists, then determining the type of satellite used, and finally displaying this information in a structured manner. This segmentation allows the system to maintain operational simplicity while providing comprehensive reliability assessment through incremental information gathering.
Solution Approach 2:
The system adds a new dimension of information display by showing satellite type icons alongside image thumbnails. This transforms the one-dimensional presence/absence determination into a multi-dimensional assessment that includes satellite type identification, enabling reliability evaluation without complicating the basic determination process.
2Adaptability or versatility
If multiple types of positioning methods are used, then positional information can be obtained in various environments, but accuracy varies depending on satellite environment and system types
Solution Approach 1:
Different satellite types are represented by distinct visual icons and color schemes in the display interface. GPS satellites have one visual representation, while QZSS satellites have another, allowing users to quickly identify the positioning method used and estimate accuracy based on the visual cues provided for each satellite type.
3Ease of operation
If manual positional information input is allowed, then images without positional information can be supplemented, but wrong information may be input
Solution Approach 1:
The system provides visual feedback by displaying icons that indicate how positional information was obtained (automatic satellite-based vs. manual input). This feedback mechanism allows users to identify manually input positions and verify their accuracy, reducing the risk of propagating incorrect information while maintaining the ease of manual supplementation.

AI summary
A display control apparatus includes a storage unit configured to store image data associated with positional information, a determination unit configured to determine whether information representing a type of satellite used for determining the positional information associated with the image data stored in the storage unit is associated with the image data, and a display control unit configured to control, in accordance with a result of the determination performed by the determination unit, display of information representing a type of satellite used for determining the positional information associated with the image data in a form in which the type of satellite is recognizable.
