  • Abstract
    A good automatic white balancing algorithm is an essential image pre-processing component in consumer digital still cameras, and it can greatly improve the final image quality. In this paper, an automatic white balancing algorithm based on the standard deviation of RGB components of the pre-captured image is proposed. A light source model for evaluation of an automatic white balancing is also described. The simulation results show that the proposed algorithm can improve the final image quality of the captured image.
