1、Introduction of New Digital CameraI OverviewDigital cameras, digital cameras is short; also known as: Digital camera; English full name: Digital Still Camera (DSC), referred to as: Digital Camera (DC).Digital cameras, is an electronic sensor to convert optical images into electronic data camera. And
2、 ordinary cameras on film by chemical changes of silver bromide to record images of the principles of different digital camera sensor is a light-sensing charge-coupled - (zh-cn: device; zh-tw: Component) - ( CCD) or complementary metal oxide semiconductor (CMOS). In the image transmitted to a comput
3、er before will usually stored in a digital storage device (usually flash memory; floppy disk and CD Rewritable (CD-RW) has been rarely used in digital cameras, equipment).II The Working PrincipleDigital Camera is a optical, mechanical, electronic integrated products. It integrates image information
4、conversion, storage and transmission components, with digital access mode, with computer processing and real-time interactive shooting and so on. Light through the lens or lens group into the camera, the imaging device into a digital signal, digital signal through the images stored in the memory chi
5、p computing device.Digital camera is the CCD imaging device or a CMOS, the imaging component is characterized by the light through, according to the different light into electronic signals. Digital cameras first appeared in the United States, more than 20 years ago, the United States had to use it t
6、o send photos via satellite to the ground, and later converted to civilian use of digital photography and constantly expanding range of applications.Advantages:1, can immediately see the picture after picture, which provides a right not satisfied with the work immediately to remake the possibility o
7、f reducing the incidence of regret.2, only for those who want to pay for washing photographs, and other unwanted pictures can be deleted.3, color reproduction and color range are no longer dependent on film quality.4, sensitivity is no longer a result of the film and fixed. Photoelectric conversion
8、chips can provide a variety of sensitivity options.Disadvantages:1, due to the imaging devices and image processing chip conversion, optical cameras, image quality compared to the lack of layering.2, due to the various manufacturers of different image processing chip technology, imaging performance
9、of the color photos and actual objects, a different difference.3, due to a lack of core technologies in China, the latter part of the use of the higher maintenance costs.III The Product ClassificationAccording to the most common use of a digital camera can simply be divided into: single-lens reflex
10、camera, card camera, telephoto cameras, cameras and home.SLR Digital CamerasSLR means single lens reflex digital cameras, namely digital digital, single individual, lens lens, reflex reflectors abbreviation dslr. The representative of the market model is commonly found in Nikon, Canon, Pentax, Fuji
11、and so on. Such cameras typically larger, heavier.The use of electronic viewfinder evf models, but also classified as single-lens reflex type, but generally add the word similar or an indication of evf viewfinder, such as the Olympus c-2100uz, Fuji finepix 6900 and so on. The work of the SLR digital
12、 camera system, the light through the lens reach the mirror, the refraction to the top of the focusing screen and the images formed through the eyepiece and the five prism, we can see outside the viewfinder scenery. In contrast, usually only through the lcd screen digital camera or an electronic vie
13、wfinder (evf) to see the captured images. Clearly see the image directly than by processing the image to see more conducive to filming.SLR digital cameras feature a large lens can be exchanged with different specifications, it is natural advantages of SLR cameras, an ordinary digital camera can not
14、be compared.Card cameraCard camera in the industry there is no clear concept refers only to those compact shape, relatively light and slim stylish body design is a measure of the main criteria for such a digital camera. In which Sony T series, Olympus AZ1, and Casio Z series should be classified in
15、this area.Main Features: Card is not a digital camera can be cumbersome to carry; and put them in formal occasions, suit pocket and will not fall too jacket deformation; the little hand bag ladies no longer difficult to find space for the next squeeze them; in the other occasions, the camera stuffed
16、 into jeans pockets or simply hang around the neck is also acceptable.Although they function is not powerful, but the most basic exposure compensation function is standard in ultra-thin digital cameras, combined with regional or spot metering mode, these small things are sometimes still able to complete some photography. At least you can have a basic picture of the exposure control, and then with the color, clarity, contrast and other options, a lo
