   CCD industrial cameras are relatively sensitive to light. When shooting, there are often dark and bright lights. CCD industrial cameras can show better results in this respect. It is used in digital and machine vision cameras. A sensor for capturing stationary and moving objects. The CCD sensor captures the light and converts it into digital data for conversion to an image.
    CMOS sensors use a general semiconductor circuit, which is a technology that powers integrated circuits. CMOS technology can be easily integrated into sensor chips, including batteries, microprocessors, digital and smartphone cameras.

   Unlike the latest CMOS sensors, CCD industrial cameras require special manufacturing, which is usually more expensive. Therefore, CCD industrial cameras are usually of very high quality and light sensitivity, providing clear images with low noise.

   The CCD industrial camera has a very short shutter time and can capture high-speed moving objects. It has high long-term working stability, high requirements for industrial camera equipment selection, strict production process requirements, and generally can work in harsh environments. There will be no problems in long-term work. .
    From a technical point of view, the following indicators are often used to evaluate the performance of image sensors. CCD and CMOS image sensors have their own advantages and disadvantages. They are both a competing and complementary relationship in the entire image sensor market. In some cases, the two sensors are complementary and can be used in different applications. The CCD provides excellent image quality, noise immunity and flexibility in camera design. Although the size of the system is increased and the complexity is increased due to the addition of an external circuit, the circuit design can be more flexible, and the performance of the CCD camera with some special attention can be improved as much as possible.

    CCD is more suitable for applications where camera performance is very high and cost control is not strict, such as astronomical, high-definition medical X-ray images, and other scientific applications that require long exposure and strict image noise requirements.
CMOS is an image sensor that can be produced by applying large-scale semiconductor integrated circuit production processes. It has the characteristics of high yield, high integration, low power consumption and low price.

   There are many problems that need to be weighed when choosing a certain chip. The choice of industrial camera should meet the requirements of machine vision system. The choice of machine vision system should be based on the requirements of user production inspection and working condition monitoring. . Therefore, for machine vision systems and industrial cameras, no matter which kind of sensors are more powerful, their technological advancement will undoubtedly greatly promote the development of the industrial camera market and machine vision industry.
