CAMERA

A camera is a device that records and stores images. These images

may be still photographs or moving images such as

videos or movies. The term camera comes from the word camera obscura

(Latin for "dark chamber"), an early

mechanism for projecting images. The modern

camera evolved from the camera obscura.

CAMERA

Cameras may work with the light of the visible spectrum or with other

portions of the electromagnetic spectrum. A camera

generally consists of an enclosed hollow with an opening (aperture) at

one end for light to enter, and a recording or viewing surface for

capturing the light at the other end.

CAMERA

A majority of cameras have a lens positioned in front of

the camera's opening to gather the incoming light

and focus all or part of the image on the recording

surface. The diameter of the aperture is often controlled by a diaphragm mechanism,

but some cameras have a fixed-size aperture. Most

20th century cameras used photographic film as a

recording surface, while the majority of new ones now

use an electronic image sensor.

CAMERA

The still camera takes one photo each time the user presses the

shutter button. A typical movie camera

continuously takes 24 film frames per

second as long as the user holds down the shutter button, or until the shutter

button is pressed a second time.

CAMERA PHONE

A camera phone is a mobile phone

which is able to capture still

photographs (and usually video).

Since early in the 21st century the

majority of mobile phones in use are camera phones.

DIGITAL CAMERA

A digital camera (or digicam) is a camera

that takes video or still photographs, or both, digitally by recording

images via an electronic image

sensor. It is the main device used in the

field of digital photography. Most

21st century cameras are digital.

REMOTE CAMERA

A remote camera is a camera placed by a

photographer in areas where the photographer generally cannot be. This

includes areas with limited access, tight spaces

where a person is not allowed, or just another

angle so that the photographer can

simultaneously take pictures of the same

moment from different locations.

IP CAMERA

An Internet protocol camera, or IP camera, is a type of digital video camera

commonly employed for surveillance, and which

unlike analog closed circuit television

(CCTV) cameras can send and receive data via a

computer network and the Internet. Although most

cameras that do this are webcams, the term "IP

camera" is usually applied only to those used for

surveillance.

MOVIE CAMERA

The movie camera is a type of

photographic camera which takes a rapid sequence of

photographs on strips of film which was very popular for private use in the last century

until its successor, the video camera,

replaced it.

TRAFFIC CAMERA

A traffic camera is a video camera which observes vehicular traffic on a road.

TWIN-LENS REFLEX CAMERAHisA twin-lens reflex

camera (TLR) is a type of camera

with two objective lenses of the same focal length. One

of the lenses is the photographic objective or

"taking lens" (the lens that takes the picture), while the other is used for the viewfinder

system, which is usually viewed from above at

waist level.

VIDEO CAMERA

A video camera is a camera used for

electronic motion picture

acquisition, initially developed by the television industry but now common in other applications as

well.

Video cameras are used primarily in two modes.

The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required.

In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but optical disc media, hard disk, and flash memory in tapeless camcorders are all increasingly used.

VIEW CAMERA

The view camera is a type of camera first

developed in the era of the Daguerreotypeand

still in use today, though with many

refinements.It comprises a flexible

bellows which forms a light-tight seal between two

adjustable standards, one of which holds a lens, and the other a

viewfinder or a photographic film

holder.
