摘  要： 针对原有CG数字绘画色彩调控系统调控结果色差较大的问题，设计基于多媒体技术的CG数字绘画色彩调控系统。制定硬件设计框架进行硬件设计，采用电磁感应数位板进行数字绘画图像输入，选用双内存卡槽计算机进行图像显示与处理。为保证多媒体技术的正常运转，设定端媒体设备参数。完成系统硬件设计后，采用Photoshop色阶获取数字绘画色彩信息，将色彩信息还原。还原后的色彩信息代入色彩增强因子，完成数字绘画色彩调节，采用RGB色彩模式进行色彩控制程序编写。设计完成后设计对比实验，与原有系统相比，所设计系统图像与样本图像色差较小，更具有优越性。

Abstract： A CG digital painting color regulation and control system based on multimedia technology is designed to improve the color difference of the regulation and control results in the original CG digital painting color regulation and control system. The hardware design framework is established for the hardware design， the digital painting image input is performed by electromagnetic induction digital panel， and the image display and processing are carried out by means of the dual memory card slot computer. The parameters of end media equipment are set to ensure the normal operation of multimedia technology. After the completion of the hardware design of the system， the color information of digital painting is obtained by means of the Photo Shop color ramp， and then the color information is restored. The restored color information is brought into the color enhancement factor to complete the color adjustment of digital painting， and RGB color mode is used to compile the color control program. The contrast experiment is designed after completing the system design. The results show that， in comparison with the original system， the color difference between this designed system image and the sample image is smaller， which has more advantages.

随着现代科技的不断提升，计算机绘画技术飞速发展，绘画艺术表达形式层出不穷，其中最有代表性的就是CG数字绘画，以其高效、便捷的特征逐步在设计师、建筑行业以及商业插画师之间推广，并广泛的应用于动画概念设计、绘本设计、服装设计等行业之中[1]。数字绘画与传统绘画相比，无论是绘画风格与创作理念上都有本质的区别，这种区别着重体现在绘画的色彩关系上。

基础色彩与数字绘画相辅相成，通过对色彩进行把控，使绘画艺术创作进入一个崭新的时代。在各类绘图软件的支撑下，不论是对绘画作品进行修改还是效果烘托都更有优势[2]。……
