As a key component of the machine vision system, the most essential function of the auto focus camera is to convert the optical signal into an ordered electrical signal. Choosing the right camera is also an important part of the design of the machine vision system, the choice of the camera not only directly determines the resolution of the captured image, image quality, but also directly related to the operation mode of the entire system. The auto focus camera has many categories according to different indicators, the following is the Xuanzhan technology to introduce the more common classification of the camera:
Auto focus cameras have different classification methods according to chip type, sensor structure characteristics, scanning mode, resolution size, output signal mode, output color, output signal speed, response frequency range, etc.
1, according to the chip type: can be divided into CCD camera, CMOS camera;
2, according to the structural characteristics of the sensor: can be divided into linear array camera, surface array camera;
3, according to the scanning method: can be divided into interlace scanning camera, progressive scanning camera;
4, according to the resolution size: can be divided into standard definition camera, HD camera, 4K ultra high definition camera;
5, according to the output signal mode: can be divided into analog camera, digital camera;
6, according to the output color: can be divided into monochrome (black and white) camera, color camera;
7, according to the output signal speed: can be divided into ordinary speed camera, high-speed camera;
8, according to the response frequency range: can be divided into visible light (ordinary) camera, infrared camera, ultraviolet camera.
