Slide Show Generation Using Location-Based Video Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current slide show generation devices face challenges in properly classifying and generating slide show data from video data items due to differences in GPS data formats and the absence of common standards for location information, making it difficult to organize and display video data from various devices effectively.
Innovation Solution
A method that classifies video data items into groups based on generation location and date, using first and second classifiers to organize items with and without location information, and generates slide show data for sequential playback, ensuring appropriate selection and display of video data items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video data items from multiple devices with different GPS data formats are classified using location information, then the ability to organize video data by location is improved, but the complexity of handling non-standardized location information increases
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms various GPS data formats from different devices into a standardized location information format. This mediator layer handles the complexity of format differences internally, allowing the classification system to work with unified location data without users directly dealing with format inconsistencies.
Solution Approach 2:
The system changes the parameter format of location information by converting GPS coordinates from multiple device-specific formats into a standardized representation. This parameter transformation enables consistent classification of video data items by location while managing the diversity of source formats through systematic format conversion.
2Stability of the object's composition
If video data items are classified into groups based on generation location and date, then the coherence of slide show playback is improved, but the time required for classification and processing increases
Solution Approach 1:
The patent applies preliminary action by pre-extracting and storing location information and generation dates from video data items during the import phase, before classification is needed. This advance preparation reduces the processing time during actual classification operations, as the system already has the necessary metadata ready for grouping without needing to re-analyze the video files.
3Adaptability or versatility
If a classification system handles both video data with and without location information, then the versatility of the system is improved, but the complexity of the classification logic increases
Solution Approach 1:
The patent extracts location information as a separate, optional attribute from video data items. The classification system is designed to handle this extracted attribute when present, while automatically adapting to classify items without location information using alternative criteria such as generation date only. This extraction approach allows the system to manage heterogeneity in data attributes without requiring complex conditional logic for every possible scenario.

AI summary
A slide show generation method according to the present disclosure includes: obtaining a plurality of video data items; classifying first video data items, among the plurality of video data items, which were generated at the same generation location on the same generation date into the first group; classifying, into the first group, a second video data item among the plurality of video data items which was generated between the generation dates and times, in chronological order, of any two first video data items among the first video data items belonging to the first group; and selecting one or more video data items from among a plurality of video data items which belong to the first group and each of which is a first video data item or a second video data item, and generating slide show data for sequentially playing back the selected one or more video data items.
