    CCD: Charge Coupled Device (CCD), which uses a high-sensitivity semiconductor material, can convert light into charge, and convert it into a digital signal through an analog-to-digital converter chip, and the digital signal is saved by the flash memory or built-in hard disk card inside the camera after compression, so it can easily transmit the data to the computer, and with the help of the computer's processing means, the image can be modified according to the needs and imagination. CCDs are made up of many photosensitive units, usually measured in megapixels.

    When the surface of the CCD is illuminated by light, each photoreceptor unit reflects the charge on the component, and the signals produced by all the photoreceptors together form a complete picture.

    CMOS: Complementary metal-oxide semiconductor, like CCD, is a semiconductor that records changes in light in digital cameras. The manufacturing technology of CMOS is no different from that of general computer chips, mainly using semiconductors made of silicon and germanium, so that semiconductor with N (charged) and P (charge + charged) classes coexist on CMOS, and the current generated by these two complementary effects can be recorded and interpreted into images by processing chips.

    However, the disadvantage of CMOS is that it is too prone to noise, mainly because the early design of CMOS caused CMOS to overheat due to frequent current changes when processing rapidly changing images.

    The advantage of CCD lies in imaging, but due to the complex manufacturing process, only a few manufacturers can master it, so the manufacturing cost remains high, especially for large CCD, which is very expensive. At the same resolution, CMOS** is cheaper than CCD, but CMOS devices produce lower image quality than CCD. So far, the vast majority of consumer-grade and high-end digital cameras on the market use CCDs as sensors; CMOS sensors are used as low-end products in some cameras, and if any camera manufacturer uses CCD sensors for camera heads, manufacturers will spare no effort to hype it as a selling point, and even name it as a "digital camera".

    For a time, whether it has a CCD sensor has become one of the criteria for people to judge the grade of digital cameras.

    One of the advantages of CMOS image sensors is that the power consumption is lower than that of CCDs, which require high differential voltage to improve transmission in order to provide excellent image quality at the cost of higher power consumption. However, the CMOS image sensor converts the charge of each pixel into a voltage, amplifies it before reading, and uses a power supply to drive it, which consumes less power than a CCD. Another advantage of CMOS image sensors is that they are highly integrated with peripheral circuits, and the ADC and signal processor can be integrated, resulting in a significant reduction in size.

    A CCD camera means a camera that relies on a charge-coupled device to image the image.

    CCD, is the abbreviation of charge-coupled element, and the camera with it as the image sensor is called "CCD camera", which was popular in the 90s of the last century, and is called "card camera" because of its light and compact, and is also called "point-and-shoot camera" because of its simple operation. From the current point of view, it has few functions and low pixels, and has long been eliminated by the market in the technology iteration. But it is Youling's reputation as "electronic waste", but it has become popular among young people again, the difference is that it was trendy back then, and now it is "retro".

    In the security system, the image generation is mainly from the CCD camera, which can turn the light into an electric charge and store and transfer the charge, and can also take out the stored charge to change the voltage, so it is an ideal CCD camera element, and the CCD camera composed of it has a small size, light weight, is not affected by the magnetic field, and has the characteristics of anti-vibration and impact and is widely used.

    Retro-style film skills

    Flash is the "essence" of vintage style, especially in low-light environments. When shooting with flash, don't move too far from the camera, as if the flash is off, the subject's skin will look dull and greasy. Because the CCD camera has a low pixel, it is necessary to choose clothes and backgrounds with higher color saturation, which can make the subject more prominent and have a more rich retro texture.

    Skillfully use simple props such as umbrellas, soup spoons, and head ropes to make ** "move" and add a sense of daily life and fun. Sunlight is the best light, whether it is a landscape or a portrait, choosing to shoot on a sunny day can effectively reduce the "waste rate".

    Charge-coupled devices.

    A charge-coupled device is an image sensor that converts an optical signal into an electrical signal. In addition, CMOS, or complementary metal-oxide semiconductors, is an image sensor commonly used in digital cameras. According to the different structures, CCD can be divided into linear CCD and area array CCD.

    Area array CCDs are divided into full-frame type, frame transfer type, interline transfer type, TDI type, and so on. The function is photoelectric conversion, and the imaging device is used for imaging. The optical signal is converted into an electrical signal and then processed by the back-end circuitry.

    Main Uses of CCD:Solid-state imaging, signal processing, and mass memory are the three main uses of CCDs. Various linear array and area array image sensors have been successfully used in astronomy, remote sensing, fax, card reading, light testing and television camera and other fields, and low-light CCD and infrared CCD have shown great effects in military applications such as aerial remote air sensing and thermal imaging.

    CCD signal processing combines the advantages of both digital and analog signal processing technologies, and is widely used in medium-precision radar and communication systems.

    CCD camera stands for charge-coupled device.

    CCD, English full name: charge coupled device, Chinese full name: charge coupled element, can be called CCD image sensor. CCD is a semiconductor device.

    It is capable of converting optical images into digital signals.

    The tiny light-sensitive substance implanted in the CCD is called a pixel. The more pixels a CCD contains, the higher the resolution it provides.

    CCD acts just like film, but it converts image pixels into digital signals. There are many neatly arranged capacitors on the CCD that sense light and convert the image into a digital signal. Controlled by an external circuit, each small capacitor can transfer its charge to its neighboring capacitors.

    As an optical number conversion element, CCD cameras have been widely used.

    Division

    1) MV color CCD camera: suitable for distinguishing the details of the scene, such as distinguishing the color of clothing or scenery. The amount of information is increased by color, and the amount of information is generally considered to be 10 times that of a black-and-white CCD camera.

    2) MV monochrome CCD camera: It is used in low-light areas and areas where lighting equipment cannot be installed at night, and when only monitoring the position or movement of the scene, the resolution is usually higher than that of the color CCD camera.

    When you say CCD camera, you may be referring to a camera that uses a CCD as an image sensor.

    At present, the image sensor of digital cameras is divided into CCD and CMOS, generally speaking, the image quality and irritation control of CCD are better than CMOS, but the power consumption is large and the cost is higher. CMOS, on the other hand, is mostly used in cameras, mobile phones and other devices that do not require high imaging quality. However, with the improvement of the CMOS process, it is also used in the high-end market, but limited to the process, the yield rate of high-end CMOS is not high, so it is only used in some high-end SLR machines, mainly Canon's.

    Therefore, in the current market, most mainstream digital cameras use CCD as the image sensor (that is, the CCD camera you said), and the use of COMS is either low-end miscellaneous or some high-end SLR, which is more extreme, hehe.

    SLR has two meanings. Optically, SLR refers to single-lens reflex, that is, SLR (singlelensreflex), single-lens reflex digital camera, that is, digital, single, lens lens, Reflex reflection English abbreviation DSLR. It keeps the image in the viewing window the same as on the film, and its framing range is essentially the same as the actual shooting range, eliminating the parallax phenomenon of the rangefinder head-up camera.

    In sports, it refers to one of the tennis backhand techniques, and the tennis backhand technology includes one-handed backhand (referred to as "single-handed reflex") and two-handed backhand (referred to as "double-reflex") and single-handed backhand (referred to as "double-reflex") SLR is elegant and stable.

    SLR refers to single-lens reflection, or SLR (single-lensreflex), which is the most popular framing system today.

    In this system, the unique design of the mirrors and prisms allows the photographer to observe the image passing through the lens directly from the viewfinder. As you can see from the construction of a single-lens reflex camera, the light passing through the lens reaches the mirror, is refracted to the upper focusing screen and forms an image, and through the eyepiece and the pentaprism, we can see the outside through the viewing window. When shooting, when the shutter button is pressed, the mirror pops up, and the shutter curtain in front of the film opens at the same time, and the light (image) through the lens is projected onto the film to make the film sensitive, and then the mirror immediately returns to its original state, and the image can be seen in the viewing window again.

    This structure of the single-lens reflex camera determines that it is completely shot through the lens focus, it can make the image seen in the viewing window and the film forever the same, its framing range is basically the same as the actual shooting range, eliminating the parallax phenomenon of the rangefinder head-up framing camera, from the perspective of learning photography, it is very conducive to intuitive framing and composition.
