How to choose a CCD camera

The full English name of CCD in CD cameras is: Charge coupled Device, and the full Chinese name is: charge coupled element, also known as CCD image sensor. CCD (image sensor) uses a high-sensitivity semiconductor material that converts optical fibers into charges and converts them into digital signals through an analog-to-digital converter chip. The digital signals are compressed and stored in the flash memory or built-in hard disk card inside the camera, so the data can be easily transmitted to the computer, and the image can be modified according to needs with the help of computer processing.

There are currently two core imaging components of digital cameras: one widely uses CCD (image sensor) components, and the other is CMOS (complementary metal oxide semiconductor). Let us learn about the relevant knowledge of CCD cameras:

At the same resolution, CMOS is cheaper than CCD, but the image quality produced by CMOS devices is lower than that of CCD. Most consumer-level and high-end digital cameras on the market use CCD as a sensor.

1. 1. Suitable resolution

   According to your own needs and requirements for accuracy, reverse the pixel accuracy of the CCD camera. The formula is: camera single-directional resolution = single-directional field of view divided by theoretical accuracy.

2. 2. Sufficient camera frame rate

   For example, when shooting moving objects, you should choose a CCD camera with a higher frame rate. Generally speaking, the higher the resolution, the lower the frame rate.

3. 3. The right lens

   The size of the lens you choose to support CCD must be greater than or equal to the size of the camera's CCD sensor chip. In addition, whether the mounting base is a C, CS, or F-type interface must also match. At the same time, you must also consider the working distance of the CCD camera, whether there is enough space, etc.
