| Digital chambers reconstructed a way which we have grasped images. Study more. |

The technology reconstructed concept of a gain of live images. Earlier concept of manufacture of a constant photo has been based on pure chemistry. In 1830, Lui Daguerre, developed the first practical way to make constant photos. Today we speak about the computerised images of a photo on filmless a picture done by the device which is clever in electronic investigation and on appearance - the digital chamber.
The digital chamber takes video, still photos, or both in the digital form. It makes entry of images on the easy sensitive gauge. Instead of using a film, the arrangement of is charged-double lungs devices of sensitive semiconductors which stores electric charges, - does work. They digital made of gauges from pikselov - transform light from a scene photographed in an analogue signal which then is transformed to the digital version. One electronic system of filtering regulates colour and other picture components. Other system reduces a picture. The image at last send to a temporary warehouse and finally on a card with memory. Many compact digital chambers can make a sound recording, video and still photograph.
Images are transferred the computer where they can be changed, printed, enclosed to e-mail inserted into web pages, etc. the Most essential advantages of the digital chamber - its ability of memory and ability to show on the image screen, taken tiny video the monitor.
The technology of the digital chamber concerns with the same technology of the Registrar of the Video tape. The first VTR in 1951 has grasped images from TV, transforming the information in electric (digital) impulses and subsequently saving them on a magnetic tape. It was in 1960 when NASA has achieved the main progress, transforming analogue in digital signals by means of a space probe to plot a moon surface. Also digital display had other use in companions of the spy.
Scientists kodaka have invented the gauge first mega piksela, capable to registration of 1.4 million pikselov. In 1991, Kodak has let out the first digital system of the chamber - Nikon F-3 the chamber equipped 1.3 megapikselami, aimed at journalists. The first digital chamber for consumers which worked with house PC through a consecutive cable, was chamber Apple Quick Take 100 (1994), chamber Kodak DC40 (1995), Casio QV-11 with the monitor of the LIQUID CRYSTAL MONITOR (in the end of 1995) and Sony ` s Kibervystrel, Digital Still the Chamber (1996).
The main features of the digital chamber can be received as a result as follows:
The decision: the Decision means accuracy of a picture. The above number pikselov, the above the decision.
Memory: pictures are kept as a card file of data in the digital chamber. The size of memory defines number of a picture which can become, is kept and loaded in the computer.
Flash type: the Majority of digital chambers has constructed in range flash approximately 10-16 foots which is obliged to provide, additional light should take photos in insufficient light.
Optical Scaling: Usually two types of lenses of scaling are used that is, digital and optical. Optical lenses of scaling satisfy bolshemu to quantity of the purpose as adding details and accuracy.
Compression: This process helps to reduce the size of a file.
Lens: the length of a lens defines, how many from a scene will be entered in a picture.
The screen of the LIQUID CRYSTAL MONITOR: very interesting feature of the digital chamber - screen LCD which allows to see that, on what a photo will be similar before and after a capture of photos, leaving a room to solve, whether to erase or to rescue a photo.
In the market there are some marks of the digital chamber which sell successfully, and continuous improvement of Technology leads a way to introduction of more fascinating features in the digital chamber. |
