Expanding the presence in the market of IT products, company Creative Technology Ltd — the known manufacturer of audiosolutions has developed and has released web camera Creative WebCam Live!. The given product is intended for input of the visual information with its subsequent transmission by means of local and global computer networks

The history of personal computers includes the little more than two tens years. Despite so short history, these arrangements have received a wide circulation practically in all spheres of human activity. It both defence, and the industry, both medicine, and derivation, and even leisure.

Added with the special hardware-software resources providing an output in local and wide-area networks, they provide a high-speed information transfer between computers. Quite often such computers are allocated on considerable distance from each other, as for example, in the network the Internet possessing high information capacity. Hooked up to such network, computers become access centres to the stored world informational resources of mankind.

Besides, these arrangements are also the centres of high-speed link successfully substituting traditional mail which does not possess due level of efficiency on delivery urgent messages. Thus handled information can be presented as in the form of electronic texts, and various multimedia files.

Special attractiveness the hardware-software resources providing transmission of audio and video in real-time mode possess. It became possible thanks to appearance of high-speed communication circuits, and also considerable productivity of the modern computers supplied with appropriate arrangements of input/output. These arrangements concern not only traditional mice and keyboards of desktop systems, but also both microphones, and the special videocameras known as the web camera (from English web-camera) — the cameras used for link through the Internet.

Generally speaking, cameras of this type are known for a long time. However it is necessary to recognise, that their popularity had nonconstant character. It had both growth, and lowering of interest among potential users of computer resources.

Popularity growth first of all has been linked, of course, to traditional waitings, characteristic for many new products and processing techniques. Really, with the advent of such arrangements there were a reality videophones about which so it was much written to steam tens years ago.

As to lowering it has been linked as to imperfection of a construction, and rather with much effort. To it low capacity of dial lines of the link presented nizkoskorostnymi by modems and traditional analogue phone lines was added also. And their quality to discuss it is not necessary: it extremely low, even today, not speaking about time of appearance of the first models of videocameras.

However process of perfection of input devices of a video information did not stand on a place. As a result of successes of solid-state technologies there were new high-speed photomatrixes of a high-resolution. Thanks to new protocols capacity of the analogue modems providing data transfer on traditional, commuted, to phone lines has essentially raised also. Moreover, have received a wide circulation and the special leased lines supporting very high speeds of data transfer, reaching hundreds thousand and even millions bats a second. In addition to it, productivity and functionality of personal computers have increased, whose average price nevertheless has essentially decreased for the last years.

All it promoted a new wave of popularity of web cameras as the computer industry offers wide gamma of models of these arrangements, differing the internal arrangement, functionality, hooking up interfaces, design, by etc .

As an example of such products it is possible to result modern web camera Creative WebCam Live!, created and released by company Creative Technology Ltd — the known manufacturer of popular audiosolutions for computers.

Features of a construction and usage

Web camera Creative WebCam Live! Provides reception of pictures and video: the hardware permission to 640х480, video with scanning to 30 frames in a second. Program interpolation allows to save pictures with the permission to 1024х768. It allows to use the camera for videoconferences and an exchange of instant video messages.

The separate high-quality microphone enters into a delivery package. Camera Creative WebCam Live! It is easily hooked up to the PC through port USB and can be allocated both on standard screen monitors, and on thin displays (the Photo 2).

High parametres are reached thanks to in a construction of the camera improved CMOS a sensor control with the own permission 640х480. Implementation of potential possibilities of the camera is carried out by means of applied program by support. The set applied ON includes all necessary for the organisation of libraries of maps, remote observation, camera usage in a mode of the detector of movement with transmission of short videos of fragments through LAN or the Internet, photography with delay, planning and operation recording, etc .

The example of operation with ON is presented on the Photo 3.

In the course of operation there is a possibility not only a choice of values of the permission and number of frames in second, but also such parametres as brightness, contrast, chromaticity, gamma-correction, etc. Special ON allows to edit pictures and to create various multimedia electronic messages. Certainly, except firm ON, it is possible as well application of programs from indirect manufacturers.

Estimating possibilities of web camera Creative WebCam Live!, it is necessary to mark, this arrangement not the only thing in the bar of similar products Creative Technology Ltd.
