Auto White Balance Algorithm in Digital Camera
Auto white balance (AWB) is an important function of digital camera.The purpose of white balance is to adjust the image to make it look like taken under standard light conditions.We present a new technique to detect the reference white point of image in this paper.This technique detects the white point of image by using dynamic threshold method,thus making it more flexible and more applicable compared to other algorithms.We test 50 images which were taken under different light sources,and find that this algorithm is better than or comparable to other algorithms both in subjective and objective aspects.At the same time,this algorithm has low complexity,and it can be easily applied to hardware implementation.
