Improvement and Implementation of the Adaptive and Automatic White Balance Algorithm
In order to correct the unrealistic color of the images captured by the highresolution image acquisition system in real timean improved adaptive and automatic white balance algorithm was proposed.The color temperature estimation in the YCbCr color space was completed by this algorithm,and a regulation module was added to improve the calculation precision of channel gain continuously.Compared with some other automatic white balance algorithmsit could obtain better color correction performance.The circuit design was optimized according to the characteristic of FPGA.The experiment results show that the algorithm consumes less hardware resourcesis fast in image processing and can meet the realtime requirement of highresolution image acquisition system.
