It turns out that the CCD industrial camera has such parameters

CCD is currently the most commonly used image sensor for machine vision. As a key component in the machine vision system, the CCD industrial camera's most essential function is to convert optical signals into ordered electrical signals. Choosing a suitable CCD industrial camera is an important step in the design of a machine vision system. The quality of a CCD industrial camera not only directly determines the resolution and image quality of the collected images, but is also directly related to the operating mode of the entire system.

1. 1. Resolution: The number of pixels (Pixels) of each image collected by the camera. For digital industrial cameras, it generally corresponds directly to the number of pixels of the photoelectric sensor. For analog cameras, it depends on the video format. The PAL system is 768*576 and the NTSC system is 640*480.
2. 2. Pixel Depth: The number of bits per pixel of data. Generally, 8Bit is commonly used. For digital industrial cameras, there are generally 10Bit, 12Bit, etc.
3. 3. Maximum frame rate (Frame Rate)/line rate (Line Rate): The rate at which the camera collects and transmits images. For area array cameras, it is generally the number of frames collected per second (Frames/Sec). For line array cameras, it is the number of lines collected per second (Hz).
4. 4. Exposure method (Exposure) and shutter speed (Shutter): For line array cameras, both are line-by-line exposure methods. You can choose the collection method of fixed line frequency and external trigger synchronization. The exposure time can be consistent with the line cycle, or you can set a fixed time; area array industrial cameras have frame exposure, field exposure and rolling There are several common methods such as line exposure. Digital industrial cameras generally provide the function of external triggering to collect images. The shutter speed can generally reach 10 microseconds, and high-speed industrial cameras can be even faster.
5. 5. Pixel Size: The pixel size and the number of pixels (resolution) jointly determine the size of the camera target surface. At present, the pixel size of digital industrial cameras is generally 3μm-10μm. Generally, the smaller the pixel size, the more difficult it is to manufacture and the harder it is to improve the image quality.
6. 6. Spectral response characteristics (Spectral Range): refers to the sensitivity characteristics of the pixel sensor to different light waves. The general response range is 350nm-1000nm. Some cameras add a filter in front of the target to filter out infrared light. If the system needs to be sensitive to infrared light, the filter can be removed.
