B1 = light reflectance value (LRV) of lighter area. There are two tests, a color brightness test and a color difference test. Images usually tend to have different levels of sharpness or bluriness due to parts of the image being either in-focus or out-of-focus. Consequently, most current systems deal with contrast using heuristics. Changing the monthly recurring revenue or offering longer or shorter contract terms can have a dramatic effect on TCV.
