What is the camera gray mode called?

A single tone represents an image. The gray-scale mode of camera is an exchange term of photography specialty, which refers to expressing an image with a single tone, which is used to convert a color image into a high-quality black-and-white image (with brightness effect). Up to 256 gray levels can be used to represent the image, which makes the transition of the image smoother and more delicate.
