In
this exponential World, things are often complicated – you have mind blowing
variations and too much of information – in the end unable to comprehend some
simple things … long long ago ! ~ photography was an art, only Masters could
excel. Photo studios were thriving –
remember that for my marriage in 1992, 4 roll of photos were taken [ 4 x 36 !
+/-] .. .. some had Yashicas, could take photos and in the lab say ‘ogp’ (only
good prints !) – was stumped to read a post this morning of a new Xiaomi phone
with 108 MP camera !
About
2 decades ago, I was presented a Minota Dimage digital camera that came with a
3.2 MP !! ~ it was slightly odd looking,
powered by four AA batteries and stored images on SD/MMC
cards. It had a unique LCD monitor and came with a 16MB memory card !! - it was too precious and I would take it out
may be once a month or .. .. that way
digital photography changed the way, photos were taken on rolls – now there
would be no caution, besides the greatest advantage of instantaneous look of
the photos taken .. .. Digital photography uses cameras containing arrays of
electronic photodetectors to capture images focused by a lens, as opposed to an
exposure on photographic film. The captured images are digitized and stored as
a computer file ready for further digital processing, viewing, electronic
publishing, or digital printing. Until the advent of this technology, photographs were made by exposing
light sensitive photographic film and paper, which was processed in liquid
chemical solutions to develop and stabilize the image.

The
first consumer digital cameras were marketed in the late 1990s. Professionals
gravitated to digital slowly ! some leading Camera / film roll manufacturers
went out of business as they failed to change with the tides. At the dawn of the present century, cell
phones started having cameras initially VGA cameras. Slowly,
those mobiles with higher MP cameras were doing brisk business – MPs became the
cutting edge !!
A
megapixel, often shortened to MP, is equal to 1 million pixels. A pixel is an
individual element of a digital image. The number of megapixels determines the
resolution of an image, and a digital image with more megapixels has more
resolution. A higher resolution is certainly desirable in a digital photograph,
as it means the camera uses more pixels to create the image, which should allow
for greater accuracy. On a digital camera, the image sensor records the
photograph. An image sensor is a computer chip that measures the amount of
light that travels through the lens and strikes the chip.
The image sensors contain tiny receptors,
which are called pixels. Each of these receptors can measure the light that
strikes the chip, registering the intensity of the light.
However, .. .. … ….
Logically a camera with 24 megapixels should yield better image quality
than a camera that records 8 megapixels, not necessarily 3 times and sometimes not
always too. The physical size of the
image sensor plays a more significant role in determining the image quality of
a particular camera. A larger image sensor in physical size that contains 24 MP
will have larger individual light receptors on it, while a small image sensor
in physical size that contains 30MP will have very small individual light
receptors.
A larger light receptor, or
pixel, will be able to more accurately measure the light entering the lens from
the scene than a smaller light receptor. Because of the inaccuracies in
measuring light with a small pixel, you will end up with more errors in
measurements, resulting in "noise" in the image. Noise in photo
jargon are pixels that don't appear to
be the correct colour in the photograph.
A high number of megapixels matters most when zooming in or cropping a
photo. For example, some phones let users "zoom in" without losing
quality, without an optical zoom lens. They do this by simply cropping an 4-megapixel
photo from the centre of the original 24-megapixel image captured by the
camera. Photos with more megapixels are
larger in file size, and therefore can take longer to transfer or send, and
take up more storage space. To adjust
this, most equipments [camera and mobile phones] have the option of taking
photos at lower resolution, if so desired.
Moving
away, Xiaomi introduced the Mi CC9 series some months ago. So far the company
has launched two smartphones under the series - Mi CC9 and Mi CC9e. On Monday,
the company officially confirmed to launch another smartphone under the Mi Cc9
series called the Mi CC9 Pro. Xiaomi took to Weibo -- the Chinese microblogging
site -- to announce the launch timeline of the Mi CC9 Pro. The company has
officially confirmed that the Mi CC9 Pro will launch on November 5 in Beijing. Alongside confirming the launch date of the
Mi CC9 Pro the company also revealed the key highlight of the smartphone.
Xiaomi revealed that the Mi CC9 Pro will come with 108MP
main rear camera. This is the first Xiaomi phone to use 108MP camera
sensor. The Mi CC9 Pro will likely use the Samsung 108MP camera sensor as that
is the only one available right now.
The
post also offers a loser look at the Mi CC9 Pro's rear camera setup. It reveals
that the Mi CC9 will come with five cameras on the back panel where the primary
camera will use 108MP image sensor. The smartphone will also offer 5X optical
zoom. In the same post Xiaomi said that on November 5 the company will launch a
new watch and also a TV alongside the Mi CC9 Pro. Rumours and leaks suggest that the Mi CC9 Pro
will come with a 4000mAh with 20W+ charging support inside the box.
Xiaomi
is yet to confirm the official price of the Mi CC9 Pro but rumours suggest that
the smartphone will be priced around 2599 Yuan that roughly translates to Rs
26,000.
Interesting
!
