Front Camera Low Light Pink/Purple tint.. - Xperia Z3 Compact General

Anyone got a purple overlay on their front camera when there is no light?

I get heavy purple or blueish vignetting with the front camera in low light, but only with the stock camera app.
First pic is from stock app, second one is from Google Camera.

Does anybody else see what Fuzalert2k sees when the camera is covered, i.e. dark? That means the image enhancement algorithm goes crazy in low light conditions. Does your camera work normally otherwise?
PS: there's already a thread on this: http://forum.xda-developers.com/z3-compact/general/camera-pink-spot-poll-t2933507/

Yes, the purple hue is also apparent in not-so-low light as you can see from my sample.
No, it's not the same phenomenon at all. This effect is only visible in the end result picture and it's the entire picture rather than just a spot within it. This is also not related to white balance, just seems to be a problem in the post-processing of the stock camera app specifically.

Yeah definitely not the same thing.
Look's like I'll be using Google Camera in future.
I must say Sony really dropped the ball on the Z3C camera software, and have yet to fix it or even acknowledge it.

I come from the HTC One.
The "pink hue when dark situations" was a well known problem there.
For soem time HTC used faulty camera sensors, which caused this problem.
If you experience sthis problem with your HTC One you can send your device in and get a replacement.
I hope that this is not the same wit the Z3Cs.
I for myself can't reenact this behaviour with my Z3C.

You are trying it with the front facing camera, are you?
It wouldn't make sense if it was a faulty sensor because it only happens in the stock camera app.

Now went into a completely dark room.
You are right, with the front cam, there is little bit of pink hue on the edges.
Yes, it is very "good" that it's only visible with the stock app.
Therefore the sensor should be okay.

Nexus One Camera - Problematic Photos

I have the Nexus One Running on Cyanogen 5.0.4.1 and I love it
but the camera is giving me some problems,
For some reason I always have verticals lines on my photos and
it makes to photos look very bad! I've attached a photo so you can see
on what i am talking about.
I've tried to use different settings for the camera (2-3-5 mega pixel combined
with Normal - Fine - SuperFine quality) and it maybe helped a little but
still not very good.
Is there anything that can be done to solve this BIG issue?
I mean, Rom with a fix, some configurations I did not tried or there's nothing
to do - the camera is not great?
It was very surprising for me cause the developers of the phone
and camera module never checked this? the photos look really really bad.
Will appreciate some help....
Thanks,
Guy.
it's normal for camera phone to have the lines when the condition is not enough light...
Well, not really when a device also has a flash.
My photos are crisp although it's 3MP without flash...
in short...don't expect too much from a camera phone then it will be alright.
for me it's normal because the features exist in every single camera phones (nokia models) i've owned when taken picture in poor light condition.
did it have flash when you took those photos?
if not, did you try to enable the flash so it would always flash?
i don't have lines, but the flash not always goes off when it should on automatic (with pocket cams too) but usually the pics still worked out fine
did you try fx camera?
Flash on will improve the picture... but not necessarily good enuf... for good low light photos, you need to be able to play with the camera exposure settings which most phones don't have... else, you an external light source
I had once a digital camera with the same effect in the photos.
It was a problem in the CCD sensor. It had to be repaired.
Well try and wiping the phone or Nand restoring to a back up and check if the problem still is there.
maybe its a defective camera? i dont have an issue with the camera on my nexus and im running cm 5.0.4. i think it takes wonderful photos. here are a few

guy234 curious. does this happen with all of your pictures? or ones taken inside?
If its just inside, is the lighting fluorescent? Fluorescent lighting can cause these types of lines in photographs.

I am more concerned with the pink blob in the middle of your picture than the vertical lines LOL That pink blob is so annoying really wish they would fix this. It happens to everyone when taking pictures with a white background. Look at the wall, see how it is pink in the middle? That is a major problem with the camera on this phone for me.

It looks like you have some kind of clear cover over your camera lens. Do you have some kind of case on your phone?
Megapixel does not declare quality. Megapixel is a rating of picture size so changing the MP isn't going to make a difference. Try cleaning the camera lens with a Q-tip dabbed with rubbing alcohol.
I have never seen that on my pictures so it's not normal.
Also remember to post general questions in the right place.
Here are some of my pics

TMOUS HD2 still has the pink camera spot?

ROM 2.10.531.1 (82076) WWE still has a huge pink spot in attached pictures. Looks like it's definitely a hardware problem with probably the low-quality plastic lens. Possible chromatic aberration?
yup, my phone has it too. I took some pics of a blank sheet of paper and there was a nice pink hue in the middle of the paper!
Wasn't there a software fix for this?

The released hotfix is only for 1.66 roms and LOWER, and assuming this 2.10.x rom has all previous hotfixes rolled into it.
I see.
For the record, I have the same ROM as you and I don't seem to have the spot.
Camera
I have taken probably 100 + photos and have yet to notice any spots.
In fact, so far, I am very pleased with the quality of the photos the HD2 produces. By far the best camera on any phone I have owned, and thats been quite a few...
Stock rom installed.

take a pic of a blank sheet of paper in daylight and see if any pink shows up, or anything that's white will do.

Just tried it, and no spots. Someone mentioned the lens cover, possibly a lens to lens problem. Others are not effected by this problem as well.

I'm having a problem with green tint in my pictures. And sometimes the flash makes the pictures too bright. There should be a way to disable one of the lights in the flash. You don't need it all the time in my opinon. I called tmobile about the green tint in my pics. They are sending me a new phone. Hopefully it works out ok. Has anyone else experienced this??
I'm not having this issue. I would have to say it's probably a manufacturer's error.
Have you contacted T-Mobile or HTC about it?
BTW, this phone's video and picture capabilities are actually better than my $200 Cannon, LOL!
i only get the greenish-yellow tint only when it's a picture taken with flash, lol, pick your poison, no flash for pink, flash for green-yellow!
yes i did...they are going to send me a another phone. Wish me luck
I still have it after manually patching the phone. I think it has to do with shooting outdoors in sunlight though.
I've checked my history of FUZE/Touch Pro pictures and they have a pink spot too (visible in the histogram in Picasa)!
It looks like it's common HTC camera problem that I can date back possibly to the TyTN II which explains why it still shows up in TMOUS HD2 after all the European HD2 hubbub. So much for Quietly Brilliant.
That's unfortunate for ANYONE who has experienced this "apparently" still existing issue with the camera. I have had NO such trouble, whatsoever. All of my photos have been insanely crisp, and absolutely gorgeous.
Then again, I did perform a registry tweak to increase the maximum resolution that the camera is capable of outputting.
now that you mention it
Heres some pictures i snapped all of which have a slight pinkish tint to them i didn't notice it till today. Anyone working on a fix? Or should i see if T-mobile will trade me out phones?
Normally i wouldn't care but I take a lot of pictures like all the time and this is gonna start bugging me
HHHMMMMM Interesting
Look what I found
http://pocketnow.com/thought/clarification-the-pink-spot-syndrome
let me go take a picture with my Nexus see if it does it too
Edit: Ok Im back and so i guess HTC FTL!!! lol j/k oh well i guess I'm gonna have to settle for pink.
I'm gonna try my Dads 3GS next time I see him.

So that's why I see it in my Touch Pro too! So it must be camera optics.
It can't be sensor/uv burn-in because TMOUS HD2 is brand new less a week old spending most of its time in indoors and in pouches. It's very apparent on histograms.
If it's a white balance issue, it is contradicted by the fact it's a circle and not an overall image issue. It's also NOT present on DSLRs and other normal cameras that I've used.

Camera flash adds green hue to photos?

Hi, I'm just wondering if this is a problem with my phone or if its symptomatic across all DHD's. When taking photos using flash, the photos have a quite visible green hue across it (this is of course, set to no effect). Does anyone else have this issue? Ta
I have not noticed this yet, but in what lighting conditions are you shooting ? if it's in common bulb or fluorescent lighting then it might just be your whitebalance which is off. Adjust and try again, see if you replicate the same greenish hue.
/ Magnus
I tested in a pitch black room and there's definitely a greenish/yellowish hue across the photos. Looking at the LED flash itself i can see there is a yellowish plastic cover which i assume is the cause. Very odd that they would not go for straight clear plastic.

I think the yellowish flash module is normal. All the phones I have before with flash have the "yellowish plastic" background..whatever you called it. So I don't think this is causing the problem.
I too get a very yellow pic when using flash

I have the same problem. Bought two phones at once (myself and wife), one removes the normal, the other photos are very yellow. Terms of shooting the same. Original firmware, the latest.
Did you see what the solution to this problem?

Are there apps that take better photos and videos than the stock Camera app?

Hi, I don't know how various settings affect the results. However, I wish to be able to take excellent photos and videos under different conditions. Are there any good apps that take better photos and videos than the stock Camera App? I am using GB. Thanks

Perhaps it is better to talk about this via samples.
Any suggestion on better camera settings is appreciated.
I guess I may need an app that stores a set of preset settings
for taking photos/videos under different environments. Thanks.
In photo 1, I do not know why the ceiling lights are like that.
I changed various settings but there was no improvement.
In some cases, the overall color of the room changed.
In photo 2, the room appeared to be dark but it was not.
I changed the flash to auto, on along with changing other
settings. The room still appeared to be dark.
In photo 3, again, that place was not dark. Setting the flash
to auto or on did not help.
In photo 4, everything including the room appears to be somewhat yellowish.
In reality, the wall is white and the pillows are gray.

Thanks for the suggestion but I am not a professional. I don't know how various settings affect the results. By the time I have tested out various settings, things that I want to capture will have been gone.
ah now things are getting clearer . your pictures looks a little bit like something is wrong with the 'white balance' of your camera. so you can try different settings for the white balance, the default should be automatic (AWB). I'm not an photoexpert too, but maybe some one else can guide you further with this.
Thanks for pointing this out. I also tried white balance but it did not help. Perhaps I did not do it properly. Hoping somebody could provide some tips. Are the strong glares from the ceiling lights in photo 1 also caused by the white balance?

This effect on the ceiling lights is due to a hardware fault, there are no settings within the phone that can correct this. You can try, like me, and use photoshop. For me, its no problem because I have used photoshop for many years, but others are not so fortunate. This fault is well documented. Samsung know about it, yet have done nothing to correct it. The only way is to send the unit back to the retailer for a new unit. I tried three or four brand new units and they were all the same.
In general. The camera has limitations because of its size and proximity to other circuitry that may introduce noise etc. Its 8megapix with a tiny lens, so as is, I feel it does a pretty good job (apart from that pink dot that is). To get better pictures, consider post processing with photoshop. If that's not an option, and quite frankly I would not recommend purchasing it just for pics from any camphone, try the GIMP, its free and does an awful lot to enhance your pics. You can find the GIMP here www.gimp.org it will run on linux, windows and the Mac
Hope that helps
So, getting something like Camera ZOOM FX won't help.

Good question. I know the S2 does, and we all know about the Galaxy Note. I can see evidence of the problem on a slashgear.com presentation, and its that presentation that stopped me from going over to the S3. However, there are plenty of youtube tests where it seems pretty good. The S3 has only just been released, so it might be a while more before any issues become apparent. I think its one where you try before you buy. Personally, I'm not touching either the S3 or the 'Note until I have proof that the issue has been resolved.
Edit. The fault is commonly known as "the pink dot"
In photo 1 was the lens clean? Might sound obvious but even the slightest bit of grease or diet can affect how sources of light spear in photos. Typically in any photo I take where I light bulb or something similar is in the picture if the lens was not completely clean I got a similar effect as in photo 1

Well, there must be a lot of pink dirt around. My crappy clam phone must have pink dirt repellent, because no matter how greasy the lens gets, pics from it don't have a pink dot. Neither does my DSLR when the uv filter gets filthy, or my specs come to that. Sorry, but the dirt bit on this issue is a red herring. The camera has a defect.
I use UCam. A lot of "pro" settings and also some cool. And... you can disable shutter sound.

i think you should send the device to service/repair, because i think this is an hardware issue. i saw a lot of pictures taken by the note (not only my own device) and they are al just fine with the standard settings.
I just noticed that there is a protective film covering the back camera. Probably Samsung put it there to protect the lens. Do you think this is the cause to all of my problems? Am I supposed to remove it? For the first few days after purchase (3 weeks ago), the Note took excellent photos. As for last week and the week before that, it depends. The thin protective film has been there right from the beginning. Let's say the protective film covering the lens caused the pink dot, how do you explain why the cafe in photos 2 and 3 appeared to be dark whereas in reality, it was not. Also, photo 4 looks yellowish overall.
Hi,
Protective film would most likely create the effect on pic one. (which would be visible when a direct light source or reflection is in the frame.)
Pic two - could be a metering issue. Try changing the (cog wheel =>) metering setting and / or exposure level.
Yellowish photo is the result of incorrect "white balance". Change the white balance setting to incandescent.
I'm using both the stock ICS camera and camera zoom fx. On my previous phone the fx produced much better photos than the stock one. On my G - Note I don't see much difference.

Yes you are supposed to remove it. It does say so in the instructions that came with your phone. Check the camera after you have done this.

Nexus 6P: Camera Issues (Hot Pixels?)

6P Camera issues (hot pixels?)
I'm having issues with my brand new Nexus 6P device. While taking HDR+ photos under low light conditions, or using the flash with HDR+ I see a red dot on the right corner (vertical) or very center top (horizontal) in each single photo, while it is processing the image. After processing is done, the dot is being filtered out by the software, but I don't think this is normal... Since the dot is always in the same place. I have a few sample photos of how it looks in low light but not allowed to post links here yet.
The red dot does not appear when HDR+ is switched off, or when there's plenty of light when taking the photo.
I'm guessing nobody else has this issue, or I'm worried for nothing. It's just peculiar how the red spot is always at the exact same place, while processing. That got me wondering if there is something wrong with it.
I have not had this issue on the Nexus 6P. However, I've had this issue on a Canon digital camera before, although the dot appeared in all my photos!
What I can tell you is that stuck/hot pixels are common. In fact, almost all camera sensors are produced with some amount of bad pixels (on accident of course, just part of manufacturing tiny things), but they simply modify the firmware to edit the pixel out. This only works so long as there aren't a ton of bad pixels or no new bad pixels arise after the camera is shipped out. In the case of my Canon camera, I had to send it back under warranty for them to modify the firmware and map out the bad pixel. Later, when I got more bad pixels out of warranty, I sideloaded custom software on the camera to map out the new ones myself.
Now, what may be happening in your case is that the Nexus 6P firmware is designed to try to map out bad pixels on the fly. Does the dot appear in any final photos, or just in the processing preview? Either way, I would suggest contacting customer support immediately as your phone may require a replacement to prevent it getting any worse!

Check to see if there is any bleed on the screen, I had something vaguely similar on my s3 where I had some black dots, visible only in certain conditions, there is a screen test app which allows the screen to be on but whilst it's blacked out, at certain angles you can see the blotches.
Apogies if this isn't the case...
If not, take pics of clear and bright images eg: a white piece of paper or anything light and clear, take shots with different effects turned on on the camera to see if you can capture the speck.
If it does indeed appear to be a hardware fault the only fix is going to be a return or a hardware fix.
