Camera

A camera is a device used to take pictures, either alone or in series, with or without sound, such as with video cameras. The name is resulting from camera obscura, Latin for dark chamber, an early mechanism for projecting images in which an whole room functioned much as the internal workings of a modern photographic camera, except there was no way at this time to record the image little of physically tracing it. Cameras may work with the chart spectrum or other portions of the electromagnetic spectrum.

Every camera consists of a number of enclosed chambers, with an opening or aperture at one end for light to go into, a recording or viewing surface for capturing the light at the other conclusion. This diameter of the aperture is often forbidden by a diaphragm mechanism, but some cameras have a fixed-size opening.

Video and digital cameras use electronics, frequently a charge coupled device or sometimes a CMOS sensor to detain images which can be transfer or stored in tape or computer memory within the camera for later playback or processing. Traditional cameras capture glow onto photographic film or photographic plate.
