Dual Camera Technology in Smartphones
2k16:
LG and Huawei ,both
in the last year worked with Google to make the Nexus smartphones that we got,
and then exactly one year later now here both companies also have a dual camera
smartphone out on the market. With VR(VirtualReality) having a really big year
and 360 degree video having a really big year and you could argue that the
features in smartphones over the past couple years have slowed down a little
bit, it wouldn't be a huge surprise to see a bunch of smartphones in the next
one or two years that have dual cameras on the back. One of the smart phones
with dual cameras on the back is the LG G5 it's also really interesting phone.The
thing to note is there is almost never two identical cameras its usually one
main camera and then also another secondary camera and the secondary camera
captures sort of extra information or
entirely different image that's usually given back to add to the
original, one of the starter at this whole dual camera in a smartphone thing
was the “HTC EVO 3D” back in 2011 and this one had identical cameras on the
back so two of the same camera the back module was huge and it used both of those cameras to take a slightly different image from that slightly
different angle it was stick them together from software to create a 3D image that you can
look at it on its glasses-free 3D display and, this flopped!!! but it kind of did, I mean this was back in
2011 and how many other 3D smartphones have you seen since then.
Recently a phone came out with dual camera lenses on the back was probably more recognizable is the HTC One M8, so this one had a name 4 megapixel camera on the back and a second sensors specifically for recording depth information of the whole scene, so this would be able to tell what was in your photo in the foreground, what was for the way in the background and they can apply some software effects to like fake Boca or wherever artsy stuff to take advantage of this separation , now again I wouldn't say this one also flopped either in fact the 1-series is still part of HTC's most important line of smartphones right now but this “first” one and the software wasn't that it was subpar the best. A lot of times you couldn’t even tell if it was really even using that depth information. Now in 2016 we have smartphones like the LG G5 and the Huawei P9, from the too manufactures that happened to work with Google on a smartphone last year this G5 has a regular 16 megapixel camera on the back with a regular field of view but then right next to the laser autofocus is an additional camera a super wide-angle 135-degree 8-megapixel camera for those crazy super wide shot ,so you can switch between them on the fly if you want to, so they don't really work together to add information to one image but it can be pretty fun to play with this super wide angle travel like a GoPro camera a lot of times we can get these cool Landscapes or architecture is in the city.
The Huawei P9 is the same deal primary camera and secondary
the primary is a regular RGB sensor and the secondary camera is a monochrome
sensor so it's like a black and white camera but because it's less color
information it can do additional detail and sharpness and dynamic range and
it'll take that image information and use software to stitch it together with
the original RGB image to create a much better-looking original photo, now why smartphones have dual cameras on the back it's
just sort of mix and match ,do whatever you want with it so I was expecting
Apple to probably have an iPhone 7 or 7 Pro or something like that with maybe 2
camera lenses on the back but we don't know what Apple would be doing with that
,we don't know if it would be maybe two identical image sensors doing
stereoscopic 3D or would they be like a primary secondary type of thing or the
secondary one will pick up additional color information or light values we just
don't know who we do know is it's a feature and it's not really quite up to its
full potential right now in smartphones. Or something else related to the VR we
see all these 360 degree videos all the time now on Facebook and on YouTube
obviously having a smartphone I can capture 360 degrees without an extra accessory that you have to carry around would
be pretty cool but again this is wishful thinking .
I hope you guys liked this review.
