Support electronics read the image from the sensor and transmit it to the host computer.

The camera pictured to the right, for example, uses a Sonix SN9C101 to transmit its image over USB.

the sensor and the support electronics are built on a single silicon chip to save space and manufacturing costs.

Most webcams feature built-in microphones to make video calling and videoconferencing more convenient. The USB video device class (UVC) specification allows inter-connectivity of webcams to computers without the need for proprietary device drivers.

Most consumer webcams are capable of providing VGA-resolution video at a frame rate of 30 frames per second.

As you noticed, this webcam testing tool does not require any additional software like Adobe Flash, Microsoft Silverlight or browser add-ons.Webcams are known for their low manufacturing cost and their high flexibility, making them the lowest-cost form of videotelephony.As webcams evolved simultaneously with display technologies, USB interface speeds and broadband internet speeds, the resolution went up from gradually 320×240, to 640×480, and some even offering 1280×720 (aka 720p) or 1920×1080 (aka 1080p) resolution.Despite such an easy way, you can start testing your webcam “in one click” on different devices, including laptops, smartphones, TVs, tablets and others.Regardless of the device and the operating system, as a result of testing, you will not only know if your webcam is working, but also find out a lot of useful information about it (i.e, webcam name, resolution, frame rate, number of colors, image quality and many other specifications).
