A native 16MP resolution is 4608x3456, thats a 4:3 aspect ratio, but the Note 4 says the 16MP resolution is 5312x2988 and thats a 16MP 16:9 default, fair enough, but this is where it gets interesting. The Note 4 camera sensor is the IMX240 made by Sony, the sensors native resolution is 16MP at 4:3, so how the hell is Samsung taking a 16MP 4:3 4608x3456 sensor, and producing a default 16MP 16:9 5312x2988 photo that has more pixel width then the sensor actually has? Its like Samsung magically produced pixels the sensor can't even see lol.
They advertise 16MP photos, but the only possible way for this to work is the phone takes a photo at 13MP in 16:9, and then converts the resolution to a fake pixel stretching 16MP resolution and then advertises a 16MP camera, sure its a physical 16mp sensor, but only at 4:3, not the 16:9 like they have it set to by default.
So anyone know what the deal is with this? Is the Note 4's 16MP setting really just a 13MP photo thats stretched to 16mp? Or is there some kind of sensor trickery I'm not aware of?

Unicorn blood? The bathwater of a thousand virgins?
Seriously though i think i read somewhere that the Sony sensor in the Note 4 is a customized IMX240 that that is 16:9.

*slaps forehead* of course, what was I thinking! It all makes sense meow.
A custom sensor would make sense but I'm having trouble finding specs.
I think I've figured it out, I started looking into the sensor a bit more and this mythical custom note 4 sensor, turns out there may be more truth to this then I though, the IMX240 sensor uses 1.2um pixels where as everything I've read says the Note 4 uses 1.12um pixels, so the 0.08um smaller pixels would be the missing width to make the IMX240 a 16:9 16MP sensor.
Can anyone confirm that the Note 4 really does use a custom 1.12um IMX240 sensor?
I personally think the wide angle lens is amazing..that is until you zoom in at all on a picture after it was taken now if considered taking them in 4:3 to get a true 13mp camera thinking that would result in more pixels equals better chance of retaining image quality. Please post all thought thank you
Zooming with wide angle at full resolution or cropped result in the same inkyness. Wide angle isn't really for zooming.

I mean taking a photo in wide. Going into gallery than zooming in on that photo
front camera ok
2592x1458 16:9
2592x1944 4:3
but rear camera its where it get weird
5984x3366 16:9
5520x4140 4:3
on front camera you don't lose width when change to 16:9
but on rear camera you lose width,so they could add 5984*4140 even if it will be 1.36 Ratio

this is not funny and wrong section..
No they can't add 5984*4140. This image explains.

They can't
The IMX300 which we have on our Z5 devices are Multi Aspect sensors.
In real our device have 25MP Cam's inside but due multi aspect Sony branded it to 23MP which is what a multi aspect sensor with a size of 25MP uses. That's easier for Sony because they don't have to explain why their 25MP cam can just take 23MP pics

Why is 16:9 Ratio locked to 12MP? When the main camera is 16MP, 4:3 Aspect Ratio can go up to 16MP, so why can't 16:9? And could somebody possibly develop a mod to allow 16:9 to take full capability of the camera, I would try but I don't know how to, just a question I thought I'd ask, thanks in advance for replies

16:9 just isn't a thing for 16MP. On any camera really. I'd try to explain it but I'm bad at explaining so I'll try to summarize (or at least how I like to think of it, someone can correct me). Think of megapixel as a large portion of a photo. When you have 12 it's basically 4 megapixels across and 3 megapixels tall, making 12. 16 just adds 4 more to the top or bottom row of the photo. So it's not a limitation of the phone, just of cameras in general.

The 16:9 (12MP) Toggle comes enabled on the phone out of the box (at least I think it does) (and if not, the stock rom I'm using, the Creator might have switched it, but it's not mentioned anywhere else in his thread) and 4:3 (16MP) won't let a picture fill the screen completely, I know MP isn't everything when it comes to a camera, but it's just odd that it's a 16MP main sensor with it only using 12 of 16 out of the box, it's possible I'm not comprehending this and all the last phones I've had (GS6 and LG G5) Both have had camera mods that's gave them 60FPS recordings, improvements in general, and 100% JPG Quality, I appreciate your answer, and as I've said I might be just not grasping it or not understanding the reasoning behind it, just was digging around the stock camera app came upon the setting and thought I'd ask people that know more about this stuff then me. Thank you.
It's a hardware sensor limitation in the 16mp camera for the LG V20, and while you could get an app on the market that takes 16:9 pictures on the v20 by stretching the 4:3 picture to fit the ratio, I would just accept what we have ATM considering the alternative is kinda harmful to image fidelity
EDIT: Yes there is an option to switch to 16:9 with the drop to 12mp/6-mp depending on the options you choose obviously (just looked thanks to the post Joe199799 made just before mine)
This "degradation" in Megapixel count is actually fairly normal and happens in most cameras. My previous phone had a 13MP camera but recorded 9.7MP 16:9 shots. Here's a detailed explanation for why this happens:
If you think about how a camera works, light passes through the lens to hit the sensor. Making this lens round is the easiest option to make the image projected onto the sensor as close to reality without any distortion. Making the lens another shape would distort the image, ab bit like using the wide angle camera does, which is difficult to correct in post.
The lens projects a circular image, which you want to record as much of as possible. A circular sensor could capture everything, but circular content on rectangular screens doesn't make much sense.
The next shape that takes up the most area within a circle is a square. But at the time digital image sensors were developed, computer screens had adopted ratios of 4:3 or 3:2, slight deviations from the square.
As a result, image sensors were also built in 4:3 ratios, which sacrifice some, but not too much of the entire projected image. Now, with screen ratios favouring more width, we could adapt our sensors, however, to capture images of comparable quality, lenses would have to become larger or sensor electronics would need to shrink. Neither option is particularly preferable, which is why the 4:3 ratio has stuck around and most cameras recording 16:9 images simply crop out part of a 4:3 image. Because it arguably makes sense, megapixel count refers to the entire area of the image sensor. By cropping the image, the megapixel count will obviously decrease as a certain amount of pixels is deleted.

Thank you for the explanation it's very through and fleshed out, I think I understand now
Hi everybody
This bothers me a while: When I switch from 12mp to 48mp in camera mode to do a 'wider' picture, the camera only uses a part of the screen although "full" aspect ratio is selected. In 12mp mode the whole screen is used for the camera. Am I the only one?
Thanks for your answer and explanaition (I don't have one).
BR
you have it backwards. the "full" ratio is actually cropped in order to fit the phone's screen. the 4:3 ratio has the full resolution and captures more of the image.
