Smartphone cameras step closer to high-end power

0

SEOUL, South Korea (AP) — Expect sharper, clearer selfies this year.
Samsung
Electronics Co. has beefed up the camera in its Galaxy S5 smartphone
due for April release and added smarter camera software, following Sony
and Nokia in their upgrades of handset cameras. The tweaks mean
smartphone photos, ubiquitous nowadays because of social media such as
Facebook and Twitter, will be closer in quality to images captured by
digital single-lens reflex cameras, also known as DSLR.
How to
give a super-thin smartphone the power of a DSLR camera that can capture
moving images with clarity is a key challenge for the likes of Samsung,
Sony, Nokia and LG as they try to differentiate their offerings in a
crowded handset market. Their efforts to make smartphone cameras more
powerful have taken a toll on the compact, point-and-shoot camera
market, but catching up to the high-end cameras used by professional
photographers had appeared a far-fetched ambition.
The gap is
getting narrower thanks mainly to improvements in camera software and
other technologies, but may never close completely.
The global
wireless show that wraps up in Barcelona on Thursday showed smartphone
makers using software trickery to offset their camera weaknesses:
inferior image sensors and lack of optical zoom lens. The companies are
also making photo manipulation on the phone easier to learn than
manually controlling DSLR cameras.
Instead of touting their
smartphones as thinner, lighter or bigger screened, Samsung, Sony and LG
were boasting how their latest mobile gadgets can record ultra-high
definition videos known as 4K, take big-pixel pictures without a second
of delay and capture clearer images even at a low-light settings and
when a subject is moving.
One trend in smartphone camera this year
will be phase detection autofocus, previously available only in cameras
with interchangeable lens, said Chris Chute, a director at research
company IDC.
Samsung showcased the feature in the Galaxy S5, the
latest version of the South Korean company’s flagship smartphone. It
reduces the time it takes to focus on a subject to 0.3 second so even
when the subject is moving, the image can be captured with a sharp edge,
said Seshu Madhavapeddy, Samsung’s senior vice president for U.S.
product and technology.
"Now that phones are starting to have
this, consumers will only be more likely to use phones for not just
everyday pictures, but more and more for special event photography,"
Chute said.
With the 16 megapixel rear camera in the Galaxy S5, it
is possible to preview the result of applying high dynamic range
imaging to pictures. HDR imaging usually helps create better pictures in
extreme lighting conditions but with digital cameras, it is processed
after snapping a photo.
LG showed off how its high-end G Pro 2
smartphone can selectively blur and sharpen a picture by tapping the
area that a user wants to adjust. This feature, which adds depth to a
photo, was a major trait in DSLR cameras. While DSLR cameras did this
trick in the image’s raw data by changing the lens aperture, the G Pro 2
does it through software after the photo is taken in a special mode.
The Galaxy S5 offers a similar option though less sophisticated.
Nokia
is also betting big on powerful camera features to lure buyers from
Samsung and Apple Inc. Among Nokia’s major products is the Lumia 1020
smartphone announced last year, which can take 38 megapixel images.
Larger pixels in the camera don’t necessarily mean a better picture,
which also depends on the lens and image sensors. But bigger pixels
allow taking photos with sufficient details for poster-size prints,
something that professional photographers are keen on. Other high-end
smartphone cameras are around or below 20 megapixels.
Sony’s
Xperia Z2 smartphone, announced at the Mobile World Congress, has a rear
camera with 20.7 megapixels, same as the predecessor Z1, but Sony
upgraded the camera’s video-recording power to 4K. The Z2 is also
equipped with technologies that allow users to capture moving subjects
blur-free.
All these handsets from Samsung, Sony and LG can record
ultra-HD picture quality video, something that isn’t widespread among
stand-alone cameras.
"This trend is happening much faster than most predicted," said IDC’s Chute of the 4K video
recording in high-end smartphones.
But will these moves push smartphone cameras to reach the market reserved for premium cameras over
$1,000?
"You’re
getting to the stage where cameras in high-end models are good enough
for the majority of consumers in most environments," said Nick Dillon, a
senior analyst at Ovum. But there will be a significant quality gap
between the pictures from DSLR cameras and smartphones for the
foreseeable future, he said.
One reason is the sensor. The larger the sensor is, the better the image’s quality because it can capture
more light.
"There is a limitation in the sensor size you can put in smartphones because it would make
smartphones bigger," Dillon said.
And that’s one crucial reason why professional photographers haven’t swapped their cameras for
smartphones.
Smartphone
cameras have yet to match high-end digital cameras especially in
low-light settings, said Jun Michael Park, a freelance photo journalist
in Seoul.
"I still wouldn’t switch. Smartphone’s small camera
comes in handy, but when I take pictures I always think about getting it
printed, having a show, or getting them published," Park said.
Winning over photographers like Park could be the next trophy for smartphone makers.
