White Balance Adjustment via User-Defined Color Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing white balance adjustment methods in photography lack user interference and customization, making it difficult to achieve highly individualized photographic effects, as they rely on automatic adjustments or limited preset modes that do not cater to diverse user needs.
Innovation Solution
A method and device that allow users to input and adjust white balance based on a user-defined colour temperature value, using a preset algorithm, enabling customization through manual input or selection of specific image areas, and locking the adjusted white balance for consistent results across environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic adjustment mode is used, then white balance is adjusted automatically according to external environment changes, but user interference is not allowed and customization is limited
Solution Approach 1:
The patent implements a dynamic white balance adjustment system that combines automatic adjustment with manual customization. The system allows users to switch between automatic mode, preset modes, and manual mode, enabling dynamic adaptation to different needs. Users can define custom color temperature values and select specific measurement areas, making the system flexible and adaptable to individual requirements while maintaining automation capabilities.
2Ease of manufacture
If preset environment adjustment mode is used, then limited environment modes are provided, but user individual needs cannot be satisfied
Solution Approach 1:
The patent enables parameter changes by allowing users to define custom color temperature values outside the preset ranges. Users can input specific color temperature numbers or select from a range of values, transforming the fixed preset system into a flexible parameter adjustment system. This enables infinite customization of white balance settings to achieve highly individualized photographic effects while maintaining the ease of preset options.
3Adaptability or versatility
If manual color temperature input is added, then user customization is enabled, but interface complexity increases
Solution Approach 1:
The patent implements a multi-functional interface that handles multiple input methods through a unified structure. The same interface component can accept both preset mode selections and manual color temperature inputs, as well as process both single-point and multi-point measurements. This universal interface design enables user customization without proportionally increasing system complexity.
4Measurement precision
If multiple measurement areas are supported, then measurement precision is improved, but processing complexity increases
Solution Approach 1:
The patent applies segmentation by allowing users to divide the measurement area into multiple independent regions. Users can select one or more specific areas within the image for color temperature measurement, and the system processes each selected area separately. This segmentation enables precise measurement of specific regions of interest while maintaining manageable processing complexity through selective measurement rather than comprehensive analysis of the entire image.

AI summary
A method and device for adjusting white balance are provided. The method includes acquiring a user-defined color temperature value, and adjusting white balance according to the color temperature value and a preset algorithm. Thus, a user may acquire various white balance effects through adjustment according to preferences, take individualized photographs with various effects, thereby satisfying individual requirements of the user. The user may also lock the white balance adjusted currently, and the white balance is automatically applied to another photographing environment, so as to acquire a special photograph effect, thus enabling the user to acquire a photograph with a unique artistic effect according to an individual requirement, and greatly improving the user experience.
