Camera quality - MDA II, XDA II, 2060 ROM Development

This is a question about the 1 megapixel MDA II camera...
Is the quality (or, rather, the lack of it) due to the hardware or to the software? If it's a software thing, has anyone done better camera software somewhere?

it's not 1Mpixel
i never seen a cmos based camera which took really good pictures
think it's hardware limited

Not 1 megapixel? That's new to me.

[Q] Future owner, Camera quality

Hello everyone. I've had a Note 2 since it came out 2012, and so far the Z2 is the only phone that I think is a good enough replacement. I want to get one in December for my birthday, but one thing isn't clear to me.
In a lot of reviews, the camera quality, especially in 20mp manual mode, isn't that good, it looks out of focus or has blurry spots. Other, more recent reviews, show a better camera quality, and when I handled one myself in a showroom for an hour or so, testing it against my N2, the quality was much better, like what I expected from this phone.
Were the bad reviews, like the one on GSMarena, made with pre-production phones, or are there earlier revision phones out there, with worse cameras than the more recent ones? I'm going to order mine online, I don't know if it's from newer or older stock, and as much as I browsed the forum, it isn't clear to me if there are camera differences between revisions.
Its actualy not that bad
Ill attatch some pics i took a couple months ago

20 mp manual mode may not be satisfactory, i agree. but you should decide if 20mp is necessary or necessary in what circumstances.
What Sony did is concentrating on 8mp Auto mode with extensive image post-processing and 8mp photos are pretty good (for me).
Camera isnt the only thing I've looked for in a smartphone. Looks and material quality, battery life, dust and water ressistance... together with a maybe-not-the-best-but-good camera did it for me.
Using the auto mode (8mp) is indeed fine.
Im perfectly satisfied, maybe because I dont expect much from a phone. I mean, sure, the megapixels are high these days but that doesnt change the fact that the sensors are so small and quality will always be inferior to a "real" camera.

Can Camera Performance be improved on Redmi Note 3

Can camera performance be improved with software tweaks or is it just that Redmi Note 3 uses uses bad hardware/sensor?
I suspect that the problem is related to the sensor/hardware
In poor light conditions the camera is bull****, but in good light is pretty good, idk why because the sensor is f/2.0
Yeah, I'm pretty sure, it's a hardware thingy. Numbers aren't meant anymore. You can see, the camera is 16MP with f/2.0, but it's quality says otherwise.
I compared photos taken with RN3 with Mi4i's, having f/2.0 sensor as well. The photos taken with Mi4i were crisp & clear and with RN3, were noisy & grainy. I guess, Xiaomi didn't use a good sensor to cut down the price.
I wonder if it is upscaling some phones are really like 8 MP but use software interpoling to upscale, so I guess you could try taking a picture at 8 or 13 MP and see if there is any difference - just an idea, I will test when I get some time.

I don't think this is happening. It's not a matter of lack of resolution, it's more to do with sensor quality. Xiaomi wouldn't lie about their cameras.
Guys the pixel size from the kenzo is one of the smallest on the market. In good light the pictures are pretty good. But in more dark areas the pictures are really bad, thats because of the pixel size. Its hardware limited and there aren't many software improvements. So live with it or buy another phone
Can use hardware camera from other device and patch kernel and drivers?

I have no complaints, the pictures look similar to my Samsung Galaxy Tab Pro 8.4 , perhaps because of the samsung brand cmos ..ok actually I'm not sure what sensor is in the samsung tablet,
I did notice my samsung tablet has way better closeup zoom capabilities though, where the kenzo will start to blur at same range - not a huge deal unless you need to take pictures of flowers or bugs ...etc, perhaps it has a macro mode I missed, haven't had too much time to mess around with the camera - I'll get to it eventually
(Camera)Damn that's saddening.But maybe the little software improvements can give some changes you know...
Everyone should post a sample picture from their device using the stock camera app(don't forget to turn off geo-tagging), to see if the output is similar across multiple rn3p maybe some have better/worse sensors?

Poor Camera in Redmi Note 3 - Hardware or Software issue?

Hi there,
As you guys know, camera of Redmi Note 3 performs poor in indoor conditions. But from the reports, I heard, are saying that camera manufacturer is samsung, and resolution is 16MP. Then it must not be hardware issue, right? Could it be a software issue? By software issue, I dont mean camera app, I actually meant the driver software of camera. So, what do you think? Camera is the only downside of this phone. Even cheap samsung phones below 10000₹ has higher indoor quality.
Bump.
Any response?

I am pretty sure its an hardware issue. Because area of the sensor dedicated for each individual pixel is very less. Which in turn results in less photons recieved by each pixel when in low light situatuon. This problem can be tacjled by software optimizations but it will never behave like other camera sensors with comparatively larger sensor size. Note: megapixels is not the only parameter to judge a camera.

Redmi Note 3 Camera Quality

Hi,
A camera is a very important factor for me when buying a phone,
I bought my Redmi Note 3 after reading some underwhelming reviews about the camera, thinking "oh well, how bad can the rear camera be?" - well, the camera is really under performing, very soft images, noticeable noise in almost every scenario, very disappointing.
My question is that,
Is it really a hardware issue, or just poor camera algorithms coding?
if the former, I will just look for another phone and sell mine,
otherwise, I will (try to) wait patiently until the appropriate software update will come
Thanks

Camera is nothing but decent , specially at natural light conditions.it seems great at night condition without flash due to low aperture.miui 8 greatly improved my camera experience.i found alomost zero noise in night shots. Enough for a $200 phone
I think it takes good pictures but I found that any kind of motion will blur the picture (even just walking and snapping a pic), so motion sucks, try taking a picture of a moving dog it will just be a blur, low light also sucks, but if you take still pictures under good lighting pictures look great, I think there is a soft spot for this camera it's just hard to find, also lowering the resolution to 12MP will take 16:9 widescreen photos rather then 4:3 photos in 16MP mode
Part of the problem is it never wants to increase the shutter speed properly in order to keep iso low. It tends to take most pictures at 1/25th or so, which is great for static but not for moving objects where you need a faster shutter speed to freeze motion.

low light shots are average.
daytime shots are great.
did you tweak the default settings?
which ROM are you on?....try to be on latest MM dev or china rom
also try using open camera.
at this price range, show me a phone which gives better images?
I tried all the tweaks available including using Open Camera, nothing really helped.
I ended up selling it and buying an Mi4C - the difference in photo quality is unbelievable (at a price of around 90$ new)
Had 7 different smart phones this year, and Redmi Note's camera was the weakest among them, for me it's very noticeable.

Why is the front facing camera so awful?

I'm comparing it to my old HTC 10 and the quality is night and day. It's blurry/fuzzy, the colors are washed out. It reminds me of the quality of my old cheap webcam from 10 years ago.
Because you didn't turn off all the skin toning and skin lighting junk that's on by default. I was able to shoot selfies with more detail than any model would ever want to see on themselves so I know it isn't the camera's fault.

No, everything is disabled. It's terrible quality.

My testing and photos say otherwise. Like I said, way more detail in the selfies I've taken than most people who sit for me would ever want to see in a photo. It's not the camera.
Hey, coming from a Nexus 6 ... this is a major improvement.
Okay let's settle this, 5 mp camera is not the best out there, especially compared to iPhone 8's new front facing camera or even Samsung's I guess, although I can only tell based on what I see on internet, as I don't own them. Makes me wonder why it's so hard to create a perfect phone? I mean you did almost everything perfectly right, put a damn 8 mp camera with ois or whatever and hit a home run, why did they choose this front facing camera is beyond my understanding

Because the reality is that in order to actually see a doubling of resolution, you actually have to quadruple the megapixel count. So to see twice the detail of a 5mp sensor, you would have to use a 20mp sensor. 20mp at selfie cam size would be insane. The cameras that are using 16mp selfie cameras (such as the HTC U11) are actually using the main shooter from the V30. But to squeeze that extra sensor in with OIS would require more room and produce more heat which would cause issues with amp glow on your other sensors. Digital imaging can be a real P.I.T.A. even with dedicated cameras. Cellphone cameras are a miracle that they even produce anything worthwhile. And that's usually due to being conservative in your approach to what hardware you use.

Thanks! I already learned something interesting today Is that the reason why the Nokia 8 and the HTC U11 have larger bezels as well in order to have enough room to tackle these technical challenges?

Yes, bezels really only exist to hide hardware that they haven't figured out how to downsize or place elsewhere. To get tiny bezels, you have to use tiny camera, earpiece, and proximity sensor hardware or just get rid of them. OIS units make things much bigger as you have to put a ring of motors around the object you're stabilizing. Earpieces/speakers take up a lot of space. I'm guessing Google used the headphone jack space to add more battery and the second speaker, with the second speaker adding more bezel. Proximity sensor is probably the smallest thing in the bezels. Display drivers used to be a big contributor (Moto 360 flat tire was a display driver if I remember right) but with the modern OLED panels they just, er, tuck 'em.
Not passing judgement on the quality of the selfie cam, but I notice that as with the main camera, it too has a "wide angle" setting.
But with only the single camera, necessarily this means that the non-wide setting is digitally zoomed, plus I'd bet there's heavy software correction going on to get rid of all of the wide angle distortion. Perhaps that's asking too much from a 5 MP sensor?
However, I rarely take selfies, and when I do, I'm often trying to squeeze in the other people that are with me, or some scene in the background, so maybe I'll find the native wider angle appealing? Hard to tell in-store with all the florescent lighting.

Agreed, turned all that off too and it still looks like crap.
Maybe find something better looking to shoot? The camera does really well.

Lol wow dude is talking about a selfie this guy says find something better to shoot lmao.
I've never taken an awful photo with the front facing V30 camera. I really don't understand how anyone thinks it's awful.

From my experience, it only does poorly in low light, that is, compared to 2017 flagships. I don't think it's nearly as bad a many claim it is.
If you look at a lot of of comparisons with the between the likes of the note 8, iphone x and pixel 2, it holds up really well. The biggest difference is really between the pixel 2 and pretty much every other flagship front facer, it has by far the best front facing cam on the market by a good margin imo. The v30 front cam can look really good, is just dosen't produce quite as much detail as the others, and maybe lacks in dynamic range a bit.
If you turn on flash in low light, you see better results. It’s not real flash obviously but I’ve been impressed when it gets it right.
maybe youre ugly lol jk
