Shooting Device Scene Recognition Using GPS and Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting devices struggle to recognize shooting scenes with high precision, particularly when GPS information is unavailable or when categories are catch-all and not unique to the location, leading to unreliable scene recognition.
Innovation Solution
A shooting device that utilizes GPS information to identify the shooting location and correlates position information with shooting scene data, using scene recognition algorithms to select the most similar scene candidates based on acquired images and support information, even when GPS is unavailable, and incorporates reliability and time information to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS information is used to identify shooting location, then scene recognition accuracy is improved, but reliability deteriorates when GPS information is unavailable
Solution Approach 1:
The patent introduces image recognition technology as an intermediary method to determine shooting scenes when GPS information is unavailable. The image processing unit analyzes the captured image to identify scene characteristics, serving as a backup mediator when the primary GPS-based method cannot function, thus maintaining system reliability.
Solution Approach 2:
The patent implements a dynamic switching mechanism that adapts the scene recognition method based on GPS availability. When GPS information is available, the system uses location-based recognition; when unavailable, it dynamically switches to image-based recognition. This dynamic adaptation resolves the contradiction by optimizing accuracy when possible and ensuring reliability when conditions change.
2Device complexity
If catch-all categories are used for shooting locations, then device complexity is reduced, but scene recognition accuracy deteriorates
Solution Approach 1:
The patent segments the scene recognition process into two independent components: location-based recognition (using GPS and category databases) and image-based recognition (using image processing). This segmentation allows the system to use simple catch-all categories when location data is available while falling back to detailed image analysis when needed, resolving the contradiction between simplicity and accuracy.
Solution Approach 2:
The patent creates a universal scene recognition system that can operate through multiple pathways: GPS-based category matching, image-based scene identification, or a combination of both. This multi-functionality allows the system to maintain accuracy across different operating conditions without requiring complex specialized systems for each scenario.
3Measurement precision
If multiple scene candidate information items are selected based on similarity, then scene recognition accuracy is improved, but processing time increases
Solution Approach 1:
The patent implements a partial action approach by selectively applying image-based scene recognition only when GPS information is unavailable or insufficient. When GPS data is available, the system uses the simpler location-based category matching without performing additional image analysis, thus achieving the necessary accuracy without excessive processing time.
Solution Approach 2:
The patent performs preliminary scene recognition using GPS-based category matching before considering image-based analysis. This preliminary action quickly identifies potential scenes using simple location data, and only proceeds to more time-consuming image analysis when the preliminary result is insufficient or GPS data is unavailable, optimizing the balance between accuracy and processing time.

AI summary
The present invention provides a shooting device and a program that can recognize shooting scenes according to the situation with a high degree of precision. In at least one of a case where GPS information has not been acquired by a GPS receiver 58 within a predetermined period after the GPS receiver 58 has been activated, a case where the GPS information has been acquired by the GPS receiver 58 within the predetermined period after the GPS receiver 58 has been activated but the acquired GPS information has not been stored in a database C, and a case where a subject image has been acquired by shooting without the GPS receiver 58 being activated, the shooting device recognizes the shooting scene at the current shooting location on the basis of at least one of the subject image acquired by the shooting and shooting support information.
