Image Capture Device Weather-Based White Balance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern image capture devices often produce images with undesirable color casts due to varying lighting conditions, as manual white balance settings can be incorrect and automatic settings may not always be optimal.
Innovation Solution
An image capture device system that determines its location using electromagnetic signals and retrieves weather information from a remote server to automatically adjust settings such as white balance, hue, saturation, and contrast for improved image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual white balance setting is used, then user can control color settings, but setting may be incorrect due to user error or failure to update
Solution Approach 1:
The system automatically determines location via GPS, retrieves weather information from remote servers, and adjusts white balance settings without user intervention. The processor autonomously selects optimal color temperature based on environmental conditions, eliminating the need for manual user input while ensuring accurate color representation.
Solution Approach 2:
The system continuously monitors location and weather data, using this feedback to dynamically adjust white balance settings. By comparing real-time environmental conditions with stored lighting profile data, the system automatically updates color settings to match current conditions, ensuring ongoing color accuracy.
2Extent of automation
If automatic white balance setting is used, then device automatically identifies white color, but setting may not be optimal for present lighting conditions
Solution Approach 1:
The system transitions from analyzing only local scene data to incorporating external dimensional data sources including GPS location coordinates and remote weather server information. By adding these external dimensions of environmental data, the system achieves more precise lighting condition detection than traditional scene-based automatic white balance methods.
Solution Approach 2:
The system pre-establishes a database of lighting profiles associated with specific weather conditions and locations before image capture. By retrieving relevant weather and location data in advance and matching it with pre-stored lighting characteristics, the system prepares optimal white balance settings beforehand, ensuring accurate color representation from the moment of capture.

AI summary
Disclosed herein is a method for capturing an image using an image capture device equipped with a processor. The method includes receiving an electromagnetic signal transmitted from a remote station, determining a location of the image capture device based on the received electromagnetic signal, establishing communication over a network between the image capture device and a remote server, transmitting a request to the remote server for weather information pertaining to the determined location; receiving the weather information, determining an ambient lighting value based on the weather information, capturing an image using the image capture device, and processing the captured image using the determined ambient lighting value.
