What is a computer camera?
Computer camera, also known as computer camera, computer eye, etc., it as a video input device, in the past was widely used in video conferencing, telemedicine and real-time monitoring and other aspects. In recent years, with the development of Internet technology, the speed of the network continues to improve, coupled with the maturity of the light-sensitive imaging device technology and a large number of cameras used in the manufacture of the camera, which makes it possible to reduce the price to the ordinary people can afford the level. Ordinary people can also each other through the camera in the network with images, sound conversation and communication, in addition, people can also be used for a variety of current popular digital imaging, audio and video processing.
How to buy a computer camera?
1, the choice of interface: the current computer camera has two ways to connect, parallel port and USB interface. The advantage of the parallel port is more adaptable, every machine has a parallel port, but the data transfer is slow, the practicality of the big drop, and the port camera is now belong to the elimination of the product. USB interface is the current mainstream towards the current motherboard support for the USB interface, which not only supports hot swap, and easy to install, but also the main is the rapid transmission of USB data.
2, the choice of pixels: pixel value is an important indicator of the quality of the computer camera, the higher the value of the image captured the clearer. Early production of the camera pixel value is generally in the 300,000 or so, now the mainstream pixel value should generally be in the 5 million or so. However, the pixel value does not completely determine the quality of the image, it must be compatible with the computer system, because it requires a wider data transmission channel and faster data processing capabilities; otherwise, there may be delays in image capture, stuttering phenomenon. In addition, the higher the pixel value, the more data to be processed and stored, and thus the requirement for storage devices is correspondingly high.
3, from the color to compare: the color reproduction ability of the computer camera is strong or weak, mainly through the naked eye to observe, observe the time to pay attention to the screen to reflect the color and the original object is as real and clear. Now most of the camera is equipped with a manual focus function, in the observation can be fine-tuned to the camera lens, adjusted to the most clear picture when you take a picture to carefully observe, if the camera's lens quality is good, the picture taken is very clear and bright, colorful and true.
4, through the image capture speed to judge: computer camera image capture speed, as watching a movie when the normal playback and slow playback. General quality of the camera, the image coherence will appear intermittent phenomenon, and there is a significant delay or jump frame phenomenon. A good quality camera will capture images more smoothly, with no shading or delay, and will maintain a frame rate of 20 fps.
