What is a computer camera?

Computer cameras, also known as computer cameras, computer eyes, etc., as a video input device, have been widely used in video conferencing, telemedicine and real-time monitoring in the past. In recent years, with the development of Internet technology, the continuous improvement of network speed, coupled with the maturity of photographic imaging device technology and the large amount of use in the manufacture of cameras, has made its price drop to a level that ordinary people can bear. Ordinary people can also have video and voice conversations and communication on the network through the camera, and people can also use it for current popular digital video and audio and video processing.

How to choose a computer camera?

1 , interface selection: At present, there are two kinds of connection methods for the computer camera, parallel port and USB interface. The advantage of the parallel port is that it has strong adaptability. Each machine has a parallel port, but the data transmission is slow and the practicality is greatly reduced. The parallel port camera is now a phase-out product. The USB interface is the current mainstream trend. Now the motherboard supports USB interface. It not only supports hot plugging, but also is easy to install. The main reason is that USB data transmission is fast.

2 , pixel selection: pixel value is an important indicator affecting the quality of the computer camera, the higher the value of the captured image is more clear. The pixel values ​​of the cameras produced in the early days are generally around 300,000 , and the current mainstream pixel values ​​should generally be around 5 million. 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, image capture delays and pauses may occur. In addition, the higher the pixel value, the more data needs to be processed and stored, and thus the requirements for the storage device are correspondingly high.

3 , from the color to compare: the color reproduction ability of the computer camera is strong, mainly through the naked eye to observe, when observing, pay attention to whether the color reflected on the screen is as real and clear as the original object. Most of the current cameras are equipped with manual focusing function. You can fine-tune the lens of the camera during observation. Take a picture when you adjust to the clearest picture to observe carefully. If the quality of the camera lens is good, the picture taken will be taken. Very clear and bright, colorful and true.

4 , through the speed of image capture to determine: the speed of image capture of the computer camera, as in the normal playback and slow playback when watching movies. Generally, the camera with poor quality will have intermittent image coherence and obvious delay or tabbing. A good quality camera will be smoother when capturing images, without smearing and delay, and the number of frames will remain at 20 frames per second.
