Ok, it seems like every picture taken under the conditions mentioned above(sorry forgot to write them: natural light, inside my room, pretty much a well lit room, besides the fact i didn't turn on the lights) and everything else set on auto, have the same result. I get either a blurry shot, without the antishake option and a noisy one, when having antishake on.
Also i would like to mention, that this particular behaviour happens in a rather well lit environment. The only time i get acceptable results is when i go out and shoot in the natural sunlight.
Is this normal?
You didn't list any conditions above.
Let me just add some examples, maybe you will understand what i'm talking about a little bit better

3. stock samsung camera
4. lg camera pro
Your iso settings are wrong. Change it to auto.

it's normal for a cell phone camera - or any type of small sensor camera, actually
Well then, why other camera apps shoot a little bit better? My old Samsung Omnia was a better shooter in this regard. Also, could you provide some photos too?

I did, but my iso is always on auto nevertheless
I would try three things:
- Set ISO manually. I don't have an S3, but with my S2 I get the best results by setting ISO manually.
- Turn antishake off. In general, electronic stabilization adds noise (unlike mechanical/optical stabilization which does not add noise).
- Try to hold the phone a still as possible while taking the picture.
That said, keep in mind that any small sensor camera like what you have in any phone is not going to perform well without good lighting. However the S3 should be one of the best of the phone cameras.
yes u r right that while using antishake option it produces noise thats y its off by default!! and u r wrong that it is blurry bcoz if antishake is off my gs3 takes noise free perfect pictures its has a gud BSI sensor (Cmos) try not to shake ur hands while taking pic.!

my first gs3 phone's pictures were immaculate in doors and out, but i had overheating issues so i got a replacement...this new phones camera does this...too much noise, didn't have that with the first phone the replacement phones case came damaged so i'm hoping to exchange it once more...hopefully the next phone won't have this camera problem....
I have the same issue, I've been comparing the pics with my S2 and results are really bad indoor, except with flash. much better than S2 with flash! im really puzzled
I had posted here my cam firmware version, I'm wondering if it's the camera app or else

okay....i am not sure whether you guys have knowledge about photography
exposure is measured by 3 component
ISO, shutter speed, and aperture
as long you have sufficient light (outdoor during daylight), lowest ISO will be used by the camera and it results no noise
ISO --- sensitivity to light
you will have noise or sometimes blur in door or low light situation...
that is because aperture of camera has opened wide then it results other two components compensate to maintain proper exposure
that will increase higher ISO (more noise) and shutter speed is slower to get more light ...
hope this explains why

Hello Guys, Im new to this forum with N number of Qns , because Im just a beginner of the smart phone users. I have got a new SE Xperia x10 and was very excited to capture the pictures using 8.1M camera.. But unfortunately the quality of the pictures that I have taken so far made me disappoint, still the HD video recording looks good. My question here is when the Video quality is good, how can the image quality be poor that we use the same camera for both the purpose. Also, is there any fix available to improve the camera quality, because i strongly believe that its not a hardware issue.
Thanks in advance
Most people have found that using a camera app called "Vignette" improves photos taken greatly.

Yes..

I beg your pardon if I have been so much curious.
One thread is enough.
Also, practise with the camera.
It's one of the best 8MP phones so the problem shouldn't be the phone

I really think you need to learn more about photography. Mp dont mean anything when it comes to camera quality. I take outstanding pictures with this phone...and if you would like a link to another forum on pictures taken with this camera i can show you....it will blow your mind. I already explained how to get the best out of your camera in another thread. Did you turn off image stabiliser?
Do you expect dslr quality from a smartphone? Cuz it wont happen.
I would strongly suggest practicing with your camera like flo said.

Ok, here are my settings:
Capturing Mode: Normal
Resolution: 6mp Wide (16:9) I use that more that 8mp because I like the widescreen pictures...and remember lower mp doesn't mean less quality!
Scenes: Normal
Focus Mode: Infinity...or macro for close up shots
photo light: always off
self timer: off
metering: Center weighted or average...spot metering is used for when your taking a picture and the light from the background is darkening your subject. Its not what you wanna use all the time...only for those situations when needed. average metering also known as matrix would be the most accurate.
White Balance: depends...if its cloudy outside ill use cloudy, if its bright and sunny ill use daylight or just auto. Most of the time I stick with auto. But playing with it properly gets nice results
image stabilser: always always off!
smile level: Normal
the +/- is the EV control I was talking about. yes it goes from -2 to +2.
And here is how I always always use it.
if its bright and sunny outside, or you just have alot of light, I will usually lower it to -1 or -0.7
Inside pictures, or low light situations I lower it to about -0.3 maybe -0.7. What that does if darkens the photo but eliminates low light noise.
Try that for a while and see what kind of pics you get. Also, keep a steady hand. When I take pictures with my phone I wrap both hands around the phone and hold it firmly to reduce any hand shake that might happen. I just find that works best for me.

the software is what determines the quality you are looking for. The camera will construct the picture/video information like pixel info, frames, etc. but the software is responsible for cleaning it up.

I don't think they should be in the same thread because they are different issues. Perhaps they are related, but then it would be do to a hardware issue.
What's the preferred means of posting examples?
If your having problems with both stills and videos, then it is likely related. You can attach jpg files to your post. You can upload vids to YouTube and post the links here.
Here are a few example shots.
The 1st shot is with the camera settings at default. The 2nd shot has anti-shake on. The 3rd shot has auto-contrast enabled.
As you can see they are all grainy and blurry even though I'm taking an image of something that is not moving.
The light produced from an overhead halogen. However, the pictures turn out similar under standard incandescent, fluorescent, or any other non-natural lighting. Also I tried out several other settings without any improvement (e.g. setting white balance to incandescent, setting the scene to party indoor, using macro focus instead of auto, etc.).
That's sensor grain. It happens when there is insufficient light as the sensor has to work harder to expose the scene and it heats up. Also, since the scene is so dim the camera is using a slower shutter speed, which results in some camera shake that causes a less sharp photo. Can you take a pic with the flash on? Also, if you are expecting Canon-level photography from this (or any cell phone camera) expect to be disappointed more often than not.

Cool, thanks so far. I will try it with the flash on. I have taken pictures in a lot of indoor light and if anything is moving the whole image is blurry. Sometimes it looks like the air is shimmering.
Perhaps what I need to do is to use something other than auto ISO?

Nope, just like Miami_Son said, auto flash will make the difference. That or bright enough lighting. Try it during the day time.

Like I said, in low light the camera will pick a slower shutter speed, which causes camera shake and blur of anything moving. What seems well lit to the eye is different for a camera sensor. Either use flash or turn on more lights. You can try turning up the ISO, but that can also increase grain.
Record video in 720p and the autofocus issues should go away.
Quite strange that they declared the Xperia S to be the worst performer in the group and said:
But, it does look like the 12.1MP Sony Xperia S is the least impressive of the four devices, even with its megapixel superiority. The poorer quality can possibly be attributed to its lower cost and hence, cheaper hardware

True. I am surprised to see such horrible photos taken with the Xperia S. XS can do much better than what the author managed. Pretty sure he used auto mode and didn't let the phone focus properly. Or maybe messed up the settings to make it seem worse.
well
XS camera is great and compare to my previous SGS 2, XS has fast focus and fast shutter speed.. even the color is better

The noise is caused by the small (better say tiny) light sensor on the phone. Sony makes the best sensor. I don't think any other phone uses better sensor than XS.
Photos from some phones "looks" better because they apply a stronger software noise reduction than SX does or they have a bigger apperture (e.g. HTC One X has F2.0 compare to F2.4 in XS). My solution to this is to apply noise reduction after I've loaded the photos to my PC using Lightroom.
Any way to applied it in the phone not in pc? Better is there a software to reduce the noise before shooting? You said that it's sensor was good but tiny right? So is it hardware problem ? Or software? Or both?

Can you post link to the comparo where XS beat them all ?
The original review work comes from the mobile reviewer at cnet. Having read her reviews in the past she is very apple biased and seems unable to operate phones correctly.
In her original review of the xperia s (put up against iphone 4) she complained about the xs' camera taking 'letterbox' photos and that she prefered the iphones 4/3 images. If she'd of bothered to hit the menu button when using the camera she'd of found it was set to 9mp 16/9 and that a couple of clicks would of then set it to 12mp 4/3.
So dont expect her to have used anything but full auto mode.
The manual options in the xs' camera are great with things like target iso, and multi point auto focus.
If only they'd bothered to include the jpeg compression options as the default level dratically over compresses images and introduces artifacts.
Also on her low light test (and most of the tests tbh) ... the iphones colours look artificially over saturated (post process) the noise level on the iphone is also horrific yet she complains at the rest!
It's also funny to see her complaining about the iso effect, its probably because the xs and gs3 can change there iso and the rest cant! Try having some movement in the image and then see how well the iphone copes.
What is also funny is that the images have all been resized for web display, having 50% more pixels to start with gives you more options for post processing and thus noise reduction
So if we could adjust the jpeg compression the noise would be reduce right?

That's not strictly true, the noise comes from the software raising ISO in low light, all sensors from the tiny ones in a phone to a full frame 35mm one will suffer from noise as the ISO is raised. Its just that the bigger the sensor the higher the ISO needs to before it to become a problem.
If noise is a problem then just use Neat Image, nothing comes close to it http://www.neatimage.com/
The noise in this camera is not particularly bad, tbh in low light every digital camera will have noise because of the use of higher ISO. I think the 12mp sensor also make the noise more visible...I'm not sure about the technical details though...
Sent from my LT26i using XDA
The basic gist of iso levels is as follows.
For a given amount of light hitting the sensor (metered) an exposure duration is determined.
Increasing the iso level decreases the exposure time for the same amount of light.
A shorter exposure time reduces the signal to noise ratio significantly, but it also reduces motion blur. Noise can be post processed, blur not so much.
My old nokia n95 would have exposure times of over 2 seconds in low light conditions, chance that everything remained totally motionless in this time is very small!
The exposure duration is usually stored in the exif file, I hope her original files kept all this sort of info!
The xs' camera has potential because we can change the target iso value (though compared to a still camera they're still low) we can also change the metering method as well. I haven't seen either of these features before in a phone camera.
The only thing we are missing is the ability manually specifiy exposure duration.
You are also correct in that the higher pixel density of a sensor the higher probabiltiy of noise.
Ability to take raw photo's or 100% quality jpegs would be nice (people have done mods to enable 100% jpeg quality, but I cant root my phone at present to test it as i use sky go)
Edit - Just checked the exif info on the 'original full size' images and its been wiped file sizes are interesting though.
GS3 - 2.1mb, IP4 - 2.6mb, 1X - 1.5mb, XS - 2.0mb
Have just noticed all the 1x pics are 6 megapixel images in 16:9 format which seems suspicious to me. But it says it all for the XS when it has a smaller file size than the GS3 and IP4 yet 50% more pixels.
Rough rule of thumb is that you need at least 1/2mb per megapixel to avoid any degradation on a full image (ie no patches of black or white)
I've messed with various camera settings, set them back to default, made sure the camera lens was clean, but my photos are always so damn grainy, especially in low light. Does anyone know how to fix this or why it might be happening? Does it have anything to do with a custom ROM/Kernel?

I'm not sure what rom you're running, so this might not be the complete source of your issue, but graininess in digital photography generally comes from the ISO. Higher ISO settings mean more grains, especially in low light. I've been on AOSP for so long that I can't remember if TW lets you mess with ISO settings on the stock camera, but if possible set your ISO to 200 and take a picture in good lighting and see if the graininess persists. I recommend leaving it on 200, anything more is going to be pretty noisy in most situations. for reference, set it to 800 and compare.

I have noticed anti-shake reduces the quality of photo's check to see if you have that on or off.
anti shake also cuts off quite a bit from the edges of the picture and enlarges what's left to fill the difference, thus amplifying any poor quality there to begin with.

In addition it boosts the ISO to increase the shutter speed, causing grainy photos.
Anti shake is basically Hitler
Awesome, thank you for the help guys.I'll let you know how it turns out with those settings
Yes, absolutely avoid using Anti-Shake at all costs. As has been said it attempts to increase shutter speed to reduce motion blur, but it comes at the cost of increased ISO. Don't use it if you can.

Sorry, didn't mean to sound so chippy. The fact of it is though that this is not a problem. The phone's software adjusts depending on lighting conditions so when you change the lighting it's gonna change its behaviour. Go take some pics in daylight and other real world conditions if you want to confirm whether it's operating correctly. You can always find ways to catch these algorithms out with artificial situations

Go take some pics in daylight and other real world conditions if you want to confirm whether it's operating correctly. You can always find ways to catch these algorithms out with artificial situations

Thanks...
I didn't wanna run out of my replacement period and then realise that I should have acted
Yes, this is not a problem, a reviewer showed how the camera reacted when photo was taken from two different angles, at one angle green color was dominant while on different angle it was not.

Hi guys...
How is everyone?
Kindly see the following two pics.
When the focus is on the tubelight the screen goes all yellow and thus the resulting pic as well.
but when I covered the tube light with my hand IT returns to normal the actual colour that is there.
Do any of you guys have this problem how should I get my unit replaced?
Is this even a problem or normal white balance stuff?

If you happen to still have your Poco, this condition is NOT a hardware nor a white balance problem on Poco. This is a normal behaviour of the flourescent lighting especially when the camera is using fast shutter speed. The yellowing is a phenomenon in which the camera captures the lower portion of the flicker curve, in laymans term, when the light has just turned ON and is not on its peak power yet.
But why was it using fast shutter speed? It should use low shutter speed!
You have a camera with a sensor that can capture huge amount of light at a given intensity and has the capability to use fast shutter speed in order to not blind itself (to not overblown the image). If you ever do use a slower shutter speed, there is a huge probability of the image of being overblown or for the moving subjects to have trails. You could still make some few adjustments in manual mode.
But my old smartphone renders the proper white color!
It is true, it renders white colors because it might be having a lower aperture, smaller sensor or even smaller photocells. To put it simply, it is using slower shutter speeds because it is what it can do and it is doing well with flourescent. It is not being blinded by the light because its camera configuration is not advanced enough to capture more light on a given amount of intensity, does slow shutter speed.
Put this into your mind: At a given constant white balance, a magnetic ballast flourescent lamp will still emit yellow tint/cast whenever the camera is using fast shutter speed. This is NOT an issue of the camera itself but a limitation of of the light source itself because advanced camera systems were now fast enough to capture its low power phase/state.
This phenomenon DOES show on full flrame cameras ie Nikon D90 and Canon Rebel XSI 450d, due to them having bigger sensors therefore using even more faster shutter speed. This doesn't mean that they're defective.
This phenomenon DOES NOT show on high frequency lamps such as midrange LEDs and mostly Flourescents with electronic ballast.

If you read them properly, you should know that this do happen even on Full frame cameras. The main culprit was the magnetic ballast flourescent.

Thanks for the explanation! I'm having some problems in places with that type of lights but not when pointing to them, just taking a normal picture, same picture can have that yellow tint, or not, just changing from one camera to the other one or moving around the photo a little bit....
