contrast ratio
反差比
One of measuring methods of contrast that is a description of the degree of the brightness difference between image or object and background. The definition of the contrast ratio is C&-{r}=B&-{max}/B&-{min} where B&-{max}is the maximum brightness value of image and B&-{min}is the minimum brightness value of image.
反差(对比度)的测度方法之一,它是图象或目标与背景之间亮度差异程度的一种描述。 反差比定义为C&-{r}=B&-{max}/B&-{min},其中B&-{min}为图象的最大亮度值, B&-{max}为最小亮度值。 |
