Digital Image Processor GPS Position Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital image processing devices cannot effectively store or input location-specific information, such as GPS data, into captured images, leading to a lack of contextual information for images taken in various locations.
Innovation Solution
A system and method that integrates a digital image processing device with a GPS device to receive and store position information at regular intervals, allowing for real-time storage and input of this data into image files, excluding timestamps, enabling the recording of location information on captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time wireless communication is performed between GPS receiver and image capture device, then position information can be transmitted in real-time, but the image capture device fails to add position information when it stays in a location where it has already received GPS information
Solution Approach 1:
The image capture device stores received position information in advance in a storage unit before image capture. When an image is captured, the device checks whether position information is already stored and uses that stored information to add location data to the image, ensuring reliable position information addition even when the device cannot receive new GPS information at the moment of capture.
2Measurement precision
If the image capture device continuously receives GPS information, then position information is updated in real-time, but the device cannot retain position information when it cannot receive new GPS data
Solution Approach 1:
The system performs preliminary storage of position information in the storage unit before the device loses GPS reception capability. When the device cannot receive new GPS information, the pre-stored position information is retrieved and used to add location data to captured images, preventing loss of position information.
Solution Approach 2:
The storage unit acts as a buffer or cushion that holds position information in advance. This beforehand cushioning ensures that even when the device cannot receive new GPS data, the position information is retained and can be added to images, preventing information loss during periods of GPS unavailability.

AI summary
A system and method for connecting a global positioning system (GPS) device with a digital image processing device and inputting position information into an image file captured by the digital image processing device. A system and method for inputting position information into a captured image employ a digital image processing device which generates an image file by capturing an image, and stores the image file, a GPS device which receives position information from a GPS satellite at regular time intervals; when the digital image processing device is connected with the GPS device, a GPS information storage unit which receives position information from the GPS device and stores the position information, and a GPS information input control unit which inputs position information excluding a timestamp, into an image file.
