During a final pass, the scene is tone-mapped to the desired luminancerange, and the post-process image effects are blended on top of the scene to create the final image.
在整个过程，色调映射场景到期望的亮度范围，快速处理图像效果混合到场景上以生成最终图像。

CCD imaging luminance meter of wider range measure is obtained by using CCD with the function of charge cumulation, using methods of charge and digital cumulation.
The functions can be realized by the system, for example, display in same time about image, test frame, luminance value and set parameter, and wide-range measure, etc.
