00:00:00.160 --> 00:00:07.160
When comparing the specs between the cameras on today's hottest cell phones

00:00:05.040 --> 00:00:11.480
one starts running into an awful lot of Photography specific terminology being

00:00:09.639 --> 00:00:16.760
thrown around and the term that seems to have been all the rage lately is Optical

00:00:14.200 --> 00:00:20.480
image stabilization or oi if you happen to be into the whole brevity thing now

00:00:18.880 --> 00:00:25.599
many phones offered today such as the iPhone 6 Plus are touting ois as the

00:00:23.160 --> 00:00:30.560
next great thing in cell phone camera technology and well it's not exactly new

00:00:28.760 --> 00:00:35.320
and this form of stabilization has been readily available in ordinary cameras

00:00:32.800 --> 00:00:39.719
for some years now but it's not all marketing fluff and unnecessary Fanfare

00:00:37.719 --> 00:00:45.800
either because what makes it special is not how new the idea is but how small

00:00:43.039 --> 00:00:49.320
and efficient these systems have become now in the past the only image

00:00:47.360 --> 00:00:54.039
stabilization readily offered on cell phone cameras was that of the digital

00:00:51.600 --> 00:00:58.840
variety which worked all right for minimizing that annoying bobbing effect

00:00:56.199 --> 00:01:03.879
NVIDIA footage but did squat in the way of reducing Shake shiness or motion

00:01:01.480 --> 00:01:07.600
blur that is caused by camera movement and this is where Optical image

00:01:05.360 --> 00:01:12.880
stabilizers come in they help to produce higher quality images by reacting to

00:01:10.240 --> 00:01:18.000
stimulus in real time ensuring that the path between the lens and the sensor is

00:01:15.280 --> 00:01:22.799
perfectly aligned before the subject is captured thus allowing you the user or

00:01:20.600 --> 00:01:26.640
an end software to more easily Focus the image so to accomplish this

00:01:24.479 --> 00:01:32.000
manufacturers utilize highly sensitive gyroscopic sensors in any range of two

00:01:29.320 --> 00:01:36.320
to many which provide data as to the angle and movement of the camera and

00:01:33.880 --> 00:01:40.200
some even exist specifically to provide extra functionality such as improved

00:01:38.600 --> 00:01:44.680
vertical stability while taking panoramic shots these directional

00:01:42.360 --> 00:01:49.119
sensors work in combination with tiny electromagnets that affect the angle of

00:01:46.960 --> 00:01:53.079
either the lens or the image sensor depending on the type of ois employed so

00:01:51.719 --> 00:01:57.560
the first type we'll be looking at lens-based applications are found in

00:01:55.079 --> 00:02:01.840
high-end cameras and worked by affecting the axis of the lens in response to

00:02:00.119 --> 00:02:06.439
movement keeping the image tracked on the sensor as squarely as possible the

00:02:04.439 --> 00:02:11.360
main advantage to this style is that the image seen by the user is as stable and

00:02:09.000 --> 00:02:15.319
clear as possible but it fails in applications where no distance can be

00:02:13.480 --> 00:02:18.800
created between the lens and the sensor so you're pretty much hooped if you want

00:02:17.120 --> 00:02:24.000
to jam this kind of tech into a cell phone which brings us to the second type

00:02:21.239 --> 00:02:28.760
sensor-based or inbody stabilizers which by contrast affect the angle of the

00:02:26.440 --> 00:02:32.360
image sensor in response to stimulus and have the added benefit of being able to

00:02:30.599 --> 00:02:36.720
adjust the focal length between it and the lens as well this type of

00:02:34.200 --> 00:02:40.879
stabilization can be compact enough to fit into small things like cell phones

00:02:38.640 --> 00:02:44.480
while also being a much more affordable and practical option as it prevents the

00:02:42.800 --> 00:02:49.239
user from having to haul around a bunch of really heavy not to mention expensive

00:02:46.840 --> 00:02:52.920
camera lenses of course that's not to say that sensor-based options are

00:02:50.879 --> 00:02:57.920
without their disadvantages since the image projected onto the sensor is not

00:02:55.519 --> 00:03:02.440
already stabilized negative qualities such as reduced low light Auto Focus

00:03:00.239 --> 00:03:06.360
performance can be an issue especially in instances where there is noticeable

00:03:04.120 --> 00:03:11.000
leg in the electronic viewfinder or screen image also these types of

00:03:08.599 --> 00:03:15.000
stabilizers are greatly dependent on their movement speed and the size of the

00:03:13.000 --> 00:03:19.560
lens in front of them meaning to improve long distance and Motion Performance at

00:03:17.280 --> 00:03:24.040
some point the lens must get bigger and as many of us know getting bigger to

00:03:21.840 --> 00:03:28.239
improve performance is simply not always an option speaking of improving

00:03:26.360 --> 00:03:32.599
performance Cooler Master thanks to great Partners like them fast as

00:03:30.200 --> 00:03:37.439
