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.
The video streams provided by webcams can be used for a number of purposes, each using appropriate software: Most modern webcams are capable of capturing arterial pulse rate by the use of a simple algorithmic trick.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.As a camera system's depth of field is greater for small image formats and is greater for lenses with a large f-number (small aperture), the systems used in webcams have a sufficiently large depth of field that the use of a fixed-focus lens does not impact image sharpness to a great extent.Most models use simple, focal-free optics (fixed focus, factory-set for the usual distance from the monitor to which it is fastened to the user) or manual focus.
The Wii Remote contains an image sensor with a resolution of 1024×768 pixels.
