摘　　要：基于输入图像中需要调整的肤色区域动态地移向特征肤色区域的图像动态肤色校正方法,提出了一种适用于显示器件中硬件实现的动态肤色校正简化模型,进而设计实现了实时动态肤色校正电路,并将其应用于100 cm彩色交流等离子体显示器(AC PDP)中进行验证。仿真及实验结果表明,本文提出的实时动态肤色校正方法能够使得校正后的输出图像中皮肤颜色显得更加自然生动,更趋近于人们对肤色的先验理解,从而有效地提高了AC PDP的彩色再现能力。Based on the dynamic skin color correction method in which the skin color region which is required to adjust in the input image is shifted dynamically toward the characteristic skin color region,a simple dynamic skin color correction model,which is suitable for hardware implementation in display devices,is proposed.By adopting the proposed model,a real-time dynamic skin color correction circuit is implemented and validated on a 100 cm AC PDP.The simulation and experiment results show that the skin color corrected with the proposed method in the output image becomes more natural and more vivid and accords with that perceived by people much more.Consequently,the color reproduction capability of AC PDP can be enhanced effectively.
