The difference between sensor CCD and CMOS 2026-09-02 .gtr-container-xyz123 { font-family: Verdana, Helvetica, "Times New Roman", Arial, sans-serif; color: #333; line-height: 1.6; padding: 20px; box-sizing: border-box; font-size: 14px; } .gtr-container-xyz123 p { margin-bottom: 1em; text-align: left; font-size: 14px; } .gtr-container-xyz123 h2 { font-size: 18px; font-weight: bold; color: #0000FF; margin-top: 1.5em; margin-bottom: 0.8em; text-align: left; } .gtr-container-xyz123 h3 { font-size: 16px; font-weight: bold; color: #0000FF; margin-top: 1.2em; margin-bottom: 0.6em; text-align: left; } .gtr-container-xyz123 ul { list-style: none !important; padding-left: 20px !important; margin-bottom: 1em; } .gtr-container-xyz123 ul li { position: relative !important; padding-left: 15px !important; margin-bottom: 0.5em !important; font-size: 14px; list-style: none !important; } .gtr-container-xyz123 ul li::before { content: "•" !important; color: #0000FF !important; position: absolute !important; left: 0 !important; font-size: 1.2em !important; line-height: 1 !important; } .gtr-container-xyz123 ol { list-style: none !important; padding-left: 25px !important; margin-bottom: 1em; } .gtr-container-xyz123 ol li { position: relative !important; padding-left: 20px !important; margin-bottom: 0.5em !important; font-size: 14px; list-style: none !important; } .gtr-container-xyz123 ol li::before { content: counter(list-item) "." !important; color: #0000FF !important; position: absolute !important; left: 0 !important; font-weight: bold !important; width: 18px !important; text-align: right !important; } .gtr-container-xyz123 strong { color: #0000FF; } @media (min-width: 768px) { .gtr-container-xyz123 { padding: 30px 50px; } } The sensor is the core component of the camera. It has functions such as photoelectric conversion, information storage, delay and sequential transmission of electrical signals. It has high integration and low power consumption, so it has subsequently developed rapidly. It is an indispensable key device for image acquisition and digital processing. Currently, there are two types of photosensitive chips commonly used in cameras on the market: CCD and CMOS. Below, the editor of TEO Dior Technology will introduce to you the differences between the two. 1. CCD (Charge Coupled Device) Currently, there are three structures of commonly used CCD cameras: full frame transfer, frame transfer and line transfer. Interline Transfer Among the three structures, row transfer is the most commonly used one, and most mid- and low-end products use this method. Full frame transfer (Full frame) The full frame transfer structure is the simplest, the photosensitive area and the storage area are together, and a 100% fill factor can be obtained. The disadvantage is that in order to avoid image light leakage, external light must be prevented from entering during readout. This can be achieved by using a mechanical shutter, using a strobe, or making the exposure time much longer than the readout time to minimize light leakage. Frame transfer The frame transmission structure is that the photosensitive area and the storage area are completely separated and equal in size. The exposed signal charge is transferred to the storage area at a very fast speed (usually less than 1% of the frame period) and then output line by line. It is obvious that the frame transfer sensor achieves 100% fill factor and during readout the next frame is exposed. The disadvantage is that the chip size is large and the cost is high. 2. CMOS (Complementary Metal Oxide Semiconductor) Sensor The principles of the photosensitive part of CMOS sensors and CCD sensors are the same. The difference is that in each pixel unit, in addition to the photosensitive part, there is also an amplifier and readout circuit part. The entire CMOS sensor also integrates an addressing circuit, amplifier and A/D. Comparison of the main performance of CCD and CMOS The first point is the difference in full well capacity: Since each pixel of the CMOS sensor includes a photosensitive diode, amplifier and readout circuit, and the entire sensor also includes an addressing circuit and A/D, the photosensitive area of ​​each pixel is much smaller than the surface area of ​​the pixel itself. Therefore, with the same pixel size, the full well capacity of the CMOS sensor is lower than that of the CCD sensor. The second point is the cost difference: Since CMOS sensors use the CMOS process, which is the most commonly used in general semiconductor circuits, peripheral circuits (such as AGC, CDS, timing, or DSP, etc.) can be easily integrated into the sensor chip, thus saving the cost of peripheral chips. The third point is that the CMOS sensor can be randomly addressed and can easily read out only the interesting part of the queue to increase the frame rate. The fourth point is noise difference: Since each photodiode of the CMOS sensor is equipped with an amplifier, and the amplifier is an analog circuit, it is difficult to make the results obtained by each amplifier consistent. Therefore, compared with a CCD sensor with only one amplifier at the output end of the horizontal register, the noise of the CMOS sensor will increase a lot, affecting the image quality. The fifth point is the difference in power consumption: the power consumption of CMOS sensors is lower than that of CCD sensors. To sum up, the advantage of CCD is that the image quality is better than that of CMOS, but the disadvantages are also obvious. Its process is too complex, and there are very few manufacturers that can master its technology, so the price is destined to not be cheap, especially for some large CCD components, the price is even more unacceptable. Therefore, in the current camera market, high-end cameras generally use CCD imagers to demonstrate identity and status. The biggest advantage of cmos imager is that it saves power. With the same battery and the same configuration, cmos can be used 1-2 hours longer than ccd, because it only consumes power when the circuit is connected, while ccd consumes power all the time. It is the so-called "electric tiger". Based on this, we can maximize our strengths and avoid weaknesses, and reasonably choose CCD or CMOS cameras for different applications.

Throughout the development of the entire industry, USB industrial cameras have become popular all over the world. 2.0 industrial cameras, 1394 industrial cameras and GigE industrial cameras have gradually replaced the dominant position of analog cameras and become the three mainstream digital cameras in the industrial camera market. In industrial applications, USB industrial cameras have gradually shown their application strength and product charm, and will become the new overlord of the industrial camera market. USB industrial camera 1. The cost advantage of USB industrial cameras: As the most widely used interface in the world, the cost of USB interface driver chips and driver circuits is extremely low, while the cost of the camera is mainly composed of imaging chips and circuits, interface driver chips and circuits, and casings. Since the cost of USB interface drivers is much lower than that of 1394 and GigE interface drivers, the price of USB industrial cameras is not only cheaper than the original analog cameras with analog capture cards, but also cheaper than 1394 and GigE interface cameras. The total cost of a USB industrial camera (the camera itself and supporting cables) is 15%-30% lower than other digital cameras. 2. Ease of use of USB industrial cameras: As the most widely used interface in the world, USB interfaces are equipped with 2-4 USB interfaces on various computers. USB industrial cameras can be directly connected to the USB interfaces of these computers to work stably, while 1394 cameras require a separate 1394 capture card to be installed in the computer to work. In addition, the USB interface can directly power USB industrial cameras without preparing a separate camera, while GigE cameras require a separate camera power supply. Therefore, the ease of use of the USB industrial camera is the best among the three digital cameras. 3. USB industrial cameras will continue to be upgraded in the future: As the most widely used interface in the world, the USB interface protocol is continuously promoted by world-class associations. USB3.0 is becoming the standard interface for a new generation of computers and electronic products. At present, USB3.0 industrial cameras have been released. Its transmission speed is 5 times faster than USB2.0, reaching 2.5gbit/s, 3 times faster than 1394b, and 2.5 times faster than GigE. In the next two to three years, it will become the main interface for high-speed industrial applications. 4. USB industrial camera stability: USB industrial camera is very suitable for one computer with 1-2 cameras, and has good stability. USB industrial cameras are the best choice for most medium and low-speed industrial applications and can greatly save user costs. At the same time, with the continuous popularity of USB3.0 interface, USB industrial cameras will solve the problem of high-bandwidth transmission and achieve high frame rate, high resolution, and remote real-time.

Cost advantages of USB industrial cameras: As the most widely used interface in the world, the USB interface has extremely cheap interface driver chips and driver circuits. The cost of a camera mainly consists of three parts: imaging chip and circuit, interface driver chip and circuit, and housing. The cost of the USB interface driver is much lower than that of the 1394 and GigE interface drivers. Therefore, the price of the USB industrial camera is not only cheaper than the original analog camera with an analog capture card, but also cheaper than the camera with the 1394 and GigE interface. The overall cost of USB industrial cameras (the camera itself and supporting cables) is 15%-30% lower than other digital cameras. 2. Ease of use of USB industrial cameras: USB interface is the most widely used interface in the world. Various computers come with 2-4 USB interfaces. USB industrial cameras can be directly connected to the USB interfaces of these computers to work stably, while 1394 cameras require a separate 1394 capture card to be installed in the computer to work. In addition, the USB interface can directly power USB industrial cameras without the need to prepare a separate power supply for the camera, while GigE cameras require an independent power supply to power the camera separately. Therefore, the ease of use of USB industrial cameras is the best among the three digital cameras. 3. The future continuous upgradeability of USB industrial cameras: As the most widely used interface in the world, USB interface is continuously promoted by world-class associations to upgrade the USB interface protocol. USB3.0 is becoming the standard interface for the new generation of computers and electronic products. At present, USB3.0 industrial cameras have come out. The transmission speed is 5X higher than USB2.0, reaching 2.5Gbit/s, which is 3 times the 1394B transmission speed and 2.5 times the GigE transmission speed. It will become the main interface for high-speed industrial applications in the next 2-3 years. 4. USB industrial camera stability: USB industrial cameras are very suitable for applications where one computer is equipped with 1-2 cameras, and the stability is very good. USB industrial cameras are the best choice for most medium and low-speed industrial applications and can greatly save user costs.
