Comment Comment by IvanK_net Fun fact: USB 2.0 webcams have been existing for over 10 years. USB 2.0 is 60 MB/s.A pixel of an image is 3 Bytes. A 1920x1080 FullHD image is 6.2 MB. At 30 frames per second, second of a FullHD video is 186 MB. How did they do that?Answer: frames are transferred as JPEG files. Even a cheap $15 webcam is a tiny computer (with a CPU, RAM, etc), which runs a JPEG encoder program. parent IvanK_net 4 years ago
