Map Visualization for Chronological Geotagged Image Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for visually and intuitively confirming the photographing locations of image files embedded with GPS information in chronological order, as digital cameras and mobile terminals with GPS capabilities become more prevalent, but existing solutions do not effectively display this information in a user-friendly manner.
Innovation Solution
An electronic apparatus with a storage device and display processor that displays a map image with pins and lines representing photographing locations and times, allowing users to visualize the sequence of photographing locations over time by connecting pins on the map with lines based on geotag and date/time information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GPS information and date/time information are embedded in image files, then location and timing data are preserved, but visual and intuitive confirmation of photographing locations in chronological order becomes difficult
Solution Approach 1:
The patent transforms one-dimensional data (lists of locations and times) into a two-dimensional visual representation by mapping photographing locations onto a map image with pins, and connecting them with lines that represent temporal sequences. This dimensional transformation enables intuitive visual confirmation of both spatial locations and chronological order simultaneously.
Solution Approach 2:
The patent creates visual copies of the abstract GPS and date/time information by representing each photographing location as a pin on the map and each time interval as a connecting line. These visual copies allow users to intuitively perceive the chronological sequence and spatial distribution without directly interpreting raw data.
2Ease of operation
If photographing locations are displayed on a map, then spatial distribution is visualized, but chronological sequence becomes difficult to perceive
Solution Approach 1:
The patent adds a temporal dimension to the spatial map display by using lines to connect pins representing different photographing locations. The lines visually encode the chronological sequence, allowing users to perceive both spatial distribution on the map and temporal progression through the connected path of pins.
Solution Approach 2:
The patent employs color variations in the connecting lines to indicate different time periods or intervals between photographing events. This color coding enables users to quickly distinguish chronological sequences and time-based patterns while viewing the spatial distribution on the map.
3Quantity of substance
If multiple image files with geotag information are processed, then comprehensive location data is available, but complexity of display increases
Solution Approach 1:
The patent merges multiple discrete pieces of location and time information from numerous image files into a unified visual representation on a single map image. All pins and connecting lines are integrated into one coherent display, allowing users to comprehend the entire set of photographing locations and their chronological relationships without being overwhelmed by individual data points.
Solution Approach 2:
The patent segments the large set of photographing events into individual pins on the map, with each pin representing a specific location and time point. This segmentation allows the complex data set to be broken down into manageable visual elements that can be individually perceived and collectively understood through their spatial and temporal relationships.

AI summary
According to one embodiment, an electronic apparatus includes a storage device which stores first image files includes location information and time information and a display processor which displays, on a screen, a map image, a plurality of objects on the map image, and lines on the map. Locations of the plurality of objects correspond to location information of the first image files. Shapes of the lines are determined based on location information and time information of the first image files. A line is drawn between a first object corresponding to first time information regarding a first timing of photographing and a second object corresponding to second time information regarding a second timing of photographing next to the first timing of photographing.
