Then, exposure parameters of the space camera can be calculated by setting the highest luminanceinformation measured before as the saturation luminance of the space camera.
再将该高亮度设为空间相机的饱和亮度，解算空间相机的曝光参量；

At the same time, the array of three values simplifies the complexity in the image, so even if a video is of poor quality or a different hue, the information about its relative luminance is retained.
Through this system, it is able to cut and extract photo information automatically, correct slant quickly, adjust luminance and chrominance, cut and rotate pictures, and make ratio prints.
