How to choose a suitable camera

with the vigorous development of the digital camera market, manufacturers continue to launch new products, and the functions of products are becoming more and more powerful. In the face of a variety of digital cameras and various technical parameters, it is inevitable to confuse some consumers who are not very proficient in this field. In fact, for any digital camera, the imaging quality is a matter of concern to everyone. The two points that have a direct impact on the imaging quality are the sensor and lens. In the process of use, the LCD and the medium used for storage are also two key issues. The small displacement is often detected by strain, inductance, differential transformer, eddy current and Hall sensors. As long as you pay attention to the above four points, you can choose a satisfactory digital camera

sensors and pixels

in the past, the image sensors of digital cameras used single CCD or 3CCD. For example, many Panasonic products used 3CCD. However, in 2005, Sony Handycam took the lead in installing CMOS sensors on tape dv-dcr-pc1000e. The emergence of CMOS sensors on digital cameras is a requirement for digital cameras to enter the era of high-definition. Its emergence has accelerated the process of high-definition cameras and the popularization of high-definition cameras. For digital cameras, we all have a common sense that the higher the pixel, the better the image quality. At present, mainstream products have reached more than one million pixels. At present, products with a total pixel of 3million and 4million pixels are also common in the market. If the purchase budget is sufficient, choose products with high pixels or CMOS sensors as much as possible

lens and zoom

for digital cameras, lens is like eyes. The quality of the lens also has an impact on the imaging of digital cameras. The person in charge: we will further implement the function of quality supervision and detection. Excellent lenses are the guarantee of imaging quality. As we all know, the imaging quality of German optical lens is well-known all over the world. Sony and Carl Zeiss have a long history of cooperation. Many Sony digital cameras use the famous Carl Zeiss vario sonnar t* lens, which has laid a solid foundation for the imaging quality of Sony digital cameras. In addition, Panasonic and Leica also have cooperation

the lens of digital cameras has zoom function. The more common ones use 10x Optical Zoom lens, but some products use 20x optical zoom lens. The optical lens with large zoom ratio can clearly magnify and reproduce the scenery that could not be seen in the distance in the past. Generally, digital cameras also have the function of electronic zoom, but when the electronic zoom is turned on, the image quality will be greatly affected, so there is not much practical significance

liquid crystal display screen

for any digital camera, the liquid crystal display is also very critical because it undertakes the tasks of viewfinder, playback and menu viewing. At present, the more mainstream digital camera screens have reached more than 2.5 inches. The larger the size of the screen, the better the effect can be obtained in terms of viewfinder, playback and menu operation. At present, some 3.5-inch products are gradually emerging in the LCD of digital camera. The screen has a touch function, and the menu operation can be operated intuitively on the screen, which is very convenient for those who are not very proficient in digital products. After Sony first launched the touchable screen, Canon, Panasonic and other manufacturers have also launched such products

16:9 is another popular direction of DV screens. It is said that the 16:9 display is the best size designed according to the distance between human eyes, which can make people feel the best visual impact when watching video content. In addition to DV, in fact, 16:9 widescreen mode has become popular in both LCD TVs and computer monitors

storage media

storage media of digital video cameras can be divided into four categories: magnetic tape, DVD disc, hard disk and flash memory. Hard disk and DVD disc are the mainstream products in the current market and have become the first choice of consumers. The hard disk digital camera stores the captured images in MPEG-2 format on the hard disk. It omits the steps that the previous tape digital camera needs to collect and convert formats. After connecting with the computer, it can directly burn DVD discs. The capacity of hard disk digital cameras on the market ranges from 20g to 60g, and the maximum capacity is 60g

a digital video camera using a disc as the storage medium can synchronously burn a DVD disc while shooting. If there are no too many requirements for users in the later stage, such products can be considered. At present, several major manufacturers, including Sony, Canon, Hitachi, Panasonic and Samsung, have DVD digital video camera products

summary

I believe that after reading the above words, you can have a basic understanding of digital video cameras. You should pay attention to what you need to pay attention to when shopping, and you should also be aware of being widely used. Choosing a satisfactory digital camera is only the first step towards image life. Mastering the equipment in your hand and constantly improving your shooting experience are also necessary lessons for a DV lover. (end)
