结论总结：

white balance drifting is an important issue in digital image processing, which affects the quality of images captured under varying lighting conditions.

The study demonstrates that direct methods and adaptive algorithms have their own strengths and weaknesses, but adaptive algorithms show more potential for practical applications due to their ability to adjust automatically according to different scenes.

Future research directions include the integration of artificial intelligence into self-adaptive algorithms and the development of multi-scale fusion techniques for improved stability and efficiency.

In summary, this paper provides an overview of white balance drifting phenomena in digital image processing, discusses various methods for adjusting white balance, presents experimental results and case studies, explores application fields, and offers insights into future research directions.

By addressing these issues through rigorous analysis and experimentation, we hope to contribute significantly to improving the accuracy of color reproduction in digital images across various domains such as photography artistry medical imaging virtual reality augmented reality etc., ultimately enhancing our overall understanding of white balance drifting problems in real-world scenarios
