摘要
基于RGB三基色的神光Ⅲ原型近场场图的图片需要在控制计算机上处理并调整参数,实现多图层的叠加运算。传统图像处理算法不能满足需求,利用新算法后,图片重叠过渡部分的灰度值按需求平滑过渡,没有突变现象出现,图片旋转缩放后也没有锯齿状边缘,符合近场液晶光阀(Liquid Crystal Light Valve,LCLV)场图靶的要求。
LCLV pictures of SG-Ⅲ need to be displayed in computer and adjusted by move, zoom, circumrotation and anti-color. Multi-layer pictures are superposed by one arithmetic. Traditional display arithmetic can not implement the function. The transition of superposed pictures by new arithmetic does not appear color mutation. Picture color transfers smoothly when many layers superposed. Indention brim disappears when zoom and circumrotation are performed.
