Research and Implementation of Image White Balance Based on FPGA
Abstrat Under light sources with different color temperatures,the color received by the image sensor deviates from the actual color,and color cast correction needs to be performed.In order to solve the shortcomings of existing white balance algorithms,this article proposes an improved automatic white balance algorithm.The algorithm transmits the 3 RGB channel images to the YCrCb color space,calculates the gain coefficient of the image and performs color correction.The algorithm uses FPGA as the hardware de-velopment platform and adopts parallel design,which reduces resource consumption and facilitates hardware development.Analysis of the test results shows that compared with the classic algorithm,this algorithm improves the white balance effect of color images and has good application prospects.
