The digital signal output by the digital camera, that is, the gray value of the pixel, has a special number of bits, which is called the pixel depth. For black-and-white cameras, the orientation of this value is usually 8-16bit. The pixel depth defines the number of gray levels from dark to bright. For example, for an 8bit camera, 0 means full dark and 255 means full light. A number between 0 and 255 represents a certain measure of brightness. 10bit data has 1024 gray levels and 12bit has 4096 gray levels. For each application we have to carefully consider whether a very fine gray scale is required. Upgrading from 8bit to 10bit or 12bit can indeed enhance the accuracy of measurement, but it also reduces the speed of the system and increases the difficulty of system integration (increased cables and larger size), so we must choose carefully.

The interface refers to the interface between the camera and the lens. Commonly used lens interfaces include C-mount, CS-mount, and F-mount.
