Camera Device Automatic Mode Setting via Location Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera devices provide various photographing modes but lack an automatic setting function that adapts to user requirements based on location and subject information, making it difficult for inexperienced users to take high-quality photos.
Innovation Solution
A method and device that utilize location and subject information to automatically set camera parameters by acquiring metadata from a server or local memory, allowing for intelligent camera setting and composition guidance, enabling users to capture high-quality images without manual expertise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If various photographing modes are provided to enable high quality photography, then photo quality can be improved, but the ease of operation deteriorates because inexperienced users cannot properly use or understand the different modes
Solution Approach 1:
The camera device automatically determines the user's location using GPS, retrieves appropriate photographing mode information from a server based on location data, and applies the settings without requiring user intervention. This self-service approach eliminates the need for users to understand or manually select from multiple photographing modes while still achieving high quality photos appropriate for the location.
Solution Approach 2:
Photographing mode information is pre-stored on servers for various locations before the user arrives. When the user visits a location, the camera automatically retrieves and applies the pre-prepared mode settings, eliminating the need for users to make decisions about photographing modes in the moment.
2Ease of operation
If automatic photographing mode determination based on location information is implemented, then ease of operation is improved for inexperienced users, but device complexity increases due to additional location acquisition and server communication functions
Solution Approach 1:
A server acts as an intermediary between the camera device and the photographing mode database. The camera only needs to send location information to the server and receive mode settings in return, rather than storing complex mode determination logic locally. This distributes system complexity to the server while keeping the camera device relatively simple.
Solution Approach 2:
The server provides a universal solution that can serve multiple camera devices and multiple locations. By centralizing the photographing mode information on a server, the system achieves multi-functionality where one server infrastructure supports numerous devices across various locations, reducing the complexity burden on individual camera devices.
3Adaptability or versatility
If photographing mode information is stored on a server and retrieved based on location, then adaptability is improved for different locations, but loss of time occurs due to network communication delays
Solution Approach 1:
Photographing mode information for various locations is pre-stored on the server before users need it. When users visit locations, the information is already prepared and can be quickly retrieved using location-based search, eliminating the need for real-time analysis or processing delays.

AI summary
Provided are a method of controlling photographing in a camera device such as a portable terminal, which automatically sets a photographing mode using at least one of location information of the device and subject information, and a camera device thereof. A camera captures an image during a photographing mode of the device. A controller acquires meta data corresponding to the image based on at least one of the location information and subject information included in the image. A camera setting value is determined based on the acquired meta data, and the camera is automatically set according to the determined camera setting value.
