Press Release Summary = High-end digital camera backs used by professionals are
usually separate devices from the camera bodies which they are used with. (This is
because most of the large- and medium-format camera systems in professional use at
the time that digital capture overtook film as the professional's medium of choice
were modular in nature, i.e. the camera body had multiple lenses, viewfinders,
winders and backs available for use with it to fit different needs.)
Press Release Body = A digital camera, as opposed to a film or videotape camera,
uses an electronic sensor to transform images (or video) into electronic data.
Modern digital cameras are typically multifunctional and the same device can take
photographs, video, and/or sound.
In 2005, digital cameras are starting to push traditional film cameras out of many
markets. Shrinking device sizes have recently allowed miniaturized digital cameras
to be included in multifunctional devices, such as cell phones and PDAs.
Video cameras
* Professional video cameras such as those used in television and movie
production. These typically have multiple images sensors (one per color) to
enhance resolution and color gamut. Professional video cameras usually do not
have a built-in VCR or microphone.
* Camcorders used by amateurs. These are a combination of camera and VCR to
create an all-in-one production unit. They generally include a microphone to
record sound, and feature a small LCD to watch the video during filming and
playback.
Professional modular digital camera systems
High-end digital camera backs used by professionals are usually separate devices
from the camera bodies which they are used with. (This is because most of the large-
and medium-format camera systems in professional use at the time that digital
capture overtook film as the professional's medium of choice were modular in nature,
i.e. the camera body had multiple lenses, viewfinders, winders and backs available
for use with it to fit different needs.)
Webcams
* Webcams are digital cameras attached to computers, used for video conferencing
or other purposes. Webcams can capture full-motion video as well, and some
models include microphones or zoom ability. These devices range in price from
very inexpensive to expensive higher-end models; many complex webcams have a
servo-controlled base capable of tracking facial motion with the help of
software.
Connectivity
Many digital cameras can connect directly to a computer to transfer data. USB is the
most widely used method, though some have a Fire wire port.
Integration
Some devices, like mobile phones integrates digital cameras. Mobile phone cameras
are much more sold than standalone digital ones.
Storage
Digital cameras need memory to store data. The higher one goes in pixel size, the
more memory will be needed. Cameras use a removable memory card to store data, but
the cheapest and smallest cameras may simply use fixed internal memory instead. Some
cameras come with inbuilt memory as well.
Autonomous devices
An autonomous device, such as a PictBridge printer, operates without need of a
computer. The camera connects to the printer, which then downloads and prints its
images. Some DVD recorders and television sets can read memory cards too.
