Is the camera compatible with monochrome?

There are monochrome (black and white) mode and pure monochrome in camera (black and white camera).

Either case may be good when used for applications such as contrast emphasis of edge noodles of observation objects.

Monochrome mode of color camera originally expresses color image in black and white

What is the advantage of a pure monochrome camera?

Generally, monochrome camera  is more sensitive than color camera

 

Higher sensitivity works well for adjusting the shutter speed and depth of focus.

Besides that, wavelength sensitivity characteristics are different.

The sensitivity of the sensor itself may not change very much.

However, color cameras often contain filters. Thus, most of color cameras has the wavelength cut at about 650 nm.
