Introduction
In the past, the only way people could meet other people was in person. Nowadays, people do not need to go to meet others in person, but also have the choice to meet others anywhere by the improvement of technology, which is webcam. A webcam that can check each other's appearance in real time through a computer and Internet network is an essential object used in non-face-to-face classes and business meetings in our daily life amid the Corona crisis.

Background of Webcam
It was 1991, and there was a research lab called 'Trojan Room' on one side of University of Cambridge at that time. A total of 15 computer scientists gathered here to study ways to improve wireless ATMs. They had heated debates every day, and the subject of this debate was none other than coffee. The reason is that there was only one coffee pot in this Trojan room. For them, the caffeine in coffee kept them alive on a murderous research schedule and also relieved the stress caused when ideas were blocked. However, the problem here is that some of these researchers lived in other buildings far from the Trojan Room, so they often went through countless doors and stairs to get a cup of coffee and then became annoyed at the coffee pot with only an empty barrel left. At a reason, one of the researchers, Dr. Quentin Fraser, came up with a very surprising proposal. The idea was to create a program that could install a camera near a coffee pot and view it in real time from a seated position through a network server. XCoffee, the first webcam program created in this way, takes a small-scale (128*128) image once per second and transmits it to the computer desktop through the network to see if there is any coffee left in the lab so that it can be checked in real time. In 1993, it has developed into a program that allows you to see the streets of other countries thousands of kilometers away through the Internet in real time.
