Cell Phone Cameras
A lot of myths exist regarding as to
whether the cell phone cameras are any good or not.
The fact that people require to admit that these cameras
are also digital cameras and they exhibit the same
facilities irrespective of the fact that their sizes
are much smaller and their functionalities are curtailed
due to this particular reason. Hence some introspection
needs to be done regarding the digital cameras and
cell phones in their joint venture together in the
technological world!
Looking back into the initial stages
of development the availability of low-cost, low-power
CMOS imaging modules helped to charge up the popular
craze camera enabled cell phones in today's world
that primitively began in Japan. That proved to be
contagious for the rest of the world. From young students
to even busy business people avidly annals photos
of colleagues and whatever else passes in front of
their phones. The popularity has touched sky high
and the reason being the good quality that people
seek at grass root level endeavors of photography.
Americans have the urge to seek betterment in these
areas also. They go about to seek cool new digital
camera phones that all have VGA resolution 640 x 480
pixels. This is considered a safe bet that this phone
is the most expensive model.
Much of a kind of ignorance exists apart
from all this regarding the cell phones cameras and
it crops from the fact that no benchmarks exist for
objectively comparing picture quality in image sensors,
camera modules, or end products. The helpless consumers
thus have to rely upon advertisements to tell them
much. Yet this is not a correct way to knowing a technical
device. Considering the technological portion it can
be said here that in the cell phone cameras some of
the VGA handsets offer fairly good image quality.
When you consider that the resolution comes from an
imaging module that measures only 6 mm square, its
actually pretty amazing quality. That square includes
an imaging chip, a digital signal processor (DSP)
that supports the VGA format, and a double lens that's
packaged in a light-tight module. Finding room for
this module is easy. Plus, power consumption is low
because the imaging chip is CMOS.
Considering the further improvements
in the cell phone camera technology it can be stated
here that some cell phones have incorporated conventional
CCD imaging units that are still used in most digital
cameras today. These devices require high voltage
and a bigger a battery. As a result, CMOS has taken
over in VGA-resolution applications. It provides increasingly
good image quality. All this discussion shows the
various achievements in the technology. However it
must be stated here that the cell phone cameras are
really good but they are nothing compared to the actual
digital cameras. The sole reason being that they are
much larger and contain far more features. It must
be admitted here that such comparison is irrelevant
because they are definitely two separate areas of
work in spite of the fact that they are both digital
cameras. Yet they are diverse in 100% of all their
aspects. Hence the comparison is irrelevant.
Considering all the important points
discussed in the above lines regarding the various
areas of the cell phone digital cameras it comes out
to be something that is worth appreciation. Leaving
aside all comparisons they cell phone cameras are
digital cameras that are certainly good in their areas
of applications and mass acceptance and popularity
would some day make them as advanced as their pioneer
professional digital cameras.
