2. 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.
3. 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.
4. 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.
5. 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.

7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. A traffic camera is a video camera which observes
vehicular traffic on a road.
13. HisA 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.
14. 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.
15. 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.
16. 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.
