Pink/purple 'ghosts'\'dirt' shapes on camera - Why is it happens? - Galaxy S II Q&A, Help & Troubleshooting

Everyone knows the 'pink spot' of android cameras ( seems like android's patent ).
But annoying thing is the pink/purple 'dust'/'dirt'/'ghosts'/... shapes that showing clearly at white/bright background with and without flash. mostly at the top or around the picture.
Here is a good sample (found via google) : http://www.flickr.com/photos/jonblack901/5969646528/
at the top middle of the photo you can notice a pink dirt, also at some other places of the photo, custom pink shapes.
You can see it sometimes at sky's photos if you look closer.
I found its happen at every smartphone (include iphone), could happen also when you take a picture of object with dark background with flash (the area of background have these pink shapes).
At some devices that I've checked seems like there are square shapes in different sizes, at some its looks like a random shapes...
Why is it happens? because the camera module? the lens glass? or its just a problem with firmware (even though its happens with every firmware) or a software problem?
Seems pretty weird...

You can see that effect on all kinds of cameras.. just google, this effect happens to stand alone cams too,

There is any reason to this effect? just curios why is it happens...
At each camera it looks different.

BTW, to experience - should you put a piece of screen protector on the lens glass ?
Will it decrease the quality of the photo?

[Q] Camera pink hue :( anyone else?? - SOLVED (AUTO WB/INADEQUATE LIGHTING)

Auto WB issue! Video Link showing dynamic changing in light sources: http://www.youtube.com/watch?v=0F0x1wkt5EU
This ones to all you SGS2 owners...
Today whilst takin' pics of my son, i noticed whilst pointing the camera down at my cream coloured carpet a pink hue was clearly visible in the centre of the shot. I took a snap and the hue was on definitely there... this was during the day time with only ambient light from my large bay windows...
slowly panning up across the room towards the window it seems to fade away, but directly at the light surface its unmissable...
I double checked the shot on my partners DHD, her shot was completely pink, very poor camera!!
Anyone elses S2 suffering from this? a quick google search shows this has also been an issue on other handsets such as the Nexus One and Samsung Focus...
Cheers,
Dickie
This is very important.
Can you make some photos and upload it?
if someone more have the classic tint pink of cheap cameras like other HTCs I am going to cancel my order inmediately.
Here are some untouched Macro shots taken in my backyard in fading light with the Galaxy S II, was a bit windy so the flowers kept moving:

I don't know of any sansung Focus.
Can anyone shoot to white walls or cloudy sky?
It is the faster way to see if the camera have the pink tint.

The shot! 8mp default settings

Dickie
just to add, this has been the only time ive noticed this issue, shots taken across the room show no visible signs of this, just the straight shot...
tbh, with the quality of all the other shots ive taken, its not a deal breaker for me, this phone still blows away any other ive used, and i don't find blank white walls/carpets interesting enough to take photos of...
Dickie
That sure looks like something I read about some HTC phone a while back. I'll need to check my phone to see. I wonder if it's software or hardware related.
after some testing i believe this is a software issue, specifically with the AUTO White Balance setting, as i point it to the cloudy sky out the window it looks perfect and when switched to incandescent it goes away!!
like i said before, i don't make a habit of shooting my carpet or my white walls very often!
Dickie
EDIT: when switched to Daylight mode, it also goes away, although it makes the carpet look orange for obvious reasons... Definitely a White Balance issue, the lighting and colour of the carpet requires the correct setting as opposed to the Auto mode, outside or with good lighting the Auto setting is fine! as far as i'm concerned, panic over! lol

That it isn't a white balance issue, it is a hardware problem. HTC got the same problems on a lot of devices before, and they tried to hide it tweaking the colors, but that doesnt solve the real problem.
If I were you I will return the phone for another one.

then why when i switch to the correct WB setting for the lighting i'm in does the issue disappear?? the issue only arrises in Auto mode under certain lighting conditions. just took a white sheet outside on Auto - No issue!
Dickie
Maybe in a non-auto mode they know the color temperature that software will apply to the image and then they can tweak the pink tint of the image, but with an auto mode that changes dinamically the color grade they cant adjust the pink tint.
I really dont know, but all of the pink tints problems in all other phones are hardware related issues, I don't know why this is going to be different.
i get exactly what you are saying, but i'm only going by what i'm working out on my device...
at the end of the day, like i said before, its not a deal breaker for me, and ive not had a single issue with it in other lighting conditions...
Also, ive just walked around my room allowing the camera to adjust dynamically, and it does disappear!! i have a standing lamp on, a small window on the opposite wall, and the large bay window at the front of the room, the pink hue is not permanent and is just the Auto WB not being perfect.
Its even visible on video, so i'll upload a vid of the pink disappearing as i walk around the room and the light changes dynamically! Auto WB issue for sure!!
Dickie
Just registered after seeing this...
A pink hue like you describe usually means infrared contamination, and happens on any camera to varying degree. Some black clothing in direct sunlight suffers the most.
Edit: Extreme Example: vimeo (dot) com/5637250
Regards, Matt
I'm just uploading a video to Youtube 720p - WB AUTO
You can clearly see the pink hue fading in and out as the phone auto adjusts to the varying lighting in my home, namely Incandescent light fittings, Fluorecent light fittings and daylight outside.
If i set the camera to a setting for one of those lighting conditions specifically, there is no issue in said condition.
I will update this post when its uploaded with the link - THIS IS NOT A PERMANENT HUE CAUSED BY HARDWARE - ITS SOFTWARE STRUGGLING WITH THE LIGHTING CONDITION!! - phew!!
Dickie
EDIT: the hue becomes very apparent after pointing the camera and any of the light sources directly then quickly moving to a white surface, it then gradually adjusts away...

not sure its the same buddy, it appears in the centre of the image and fades out, i'm 100% certain that this issue is WB/lighting condition related, 10mins and the link will be up if your interested...

I can't agree more there, you should have seen the same shot on the Desire HD, the carpet was entirely pink!! not just a spot in the middle..
Dickie
BTW I just checked my phone and observed the same situation as described by Dickie. After checking for myself I'm certain it's software related. They may need to tweak their auto white balance algorithm.

[Q] Is my screen defective?

So I've been looking closely at my screen lately wondering if it might be defective. Gradients seem to look bad on all SGS phones, but the gradients on my phone seem to look extra bad. They don't just look banded, they look similar to JPEG artifacting as well.
Not only that, but in certain games there's almost a visible "film" over the screen, but under the glass. The best way I can describe it is an unchanging group of lines or artifacts on top of the actual screen itself. This is quite noticeable in person, but is probably going to be hard to see in the video I post due to the fact that I'm recording a screen. My suggestion is to take a look at the bottom left-hand corner. It's most noticeable there.
The image I posted I just noticed today. On the Netflix login screen, the red beside the email and password boxes is a lot brighter than the rest of the red. This is significantly more noticeable at low brightness, but still noticeable at regular brightness where I took the picture.
Is this normal or do I have something wrong with my screen?
Thanks!
EDIT: I took another video and another picture where everything is far more apparent.

White Glowing in Pictures

Every time I take a picture that includes white, the white looks like it is glowing.
Any ideas on how to fix this?
Pic below:

Check your exposure settings, you might be set too high. You can long press on the shortcuts at the top of the screen (assuming you're on stock) and add exposure to the shortcuts if you want too, so you can change them easily. I assume you're not using a flash, right? That could be the culprit too if the subject is lit well enough.
Could be your case also. IF you have one of those clear cases they tend to cause the camera to do that when the flash goes off.....not with all but some...just an idea
Turn the exposure down.
Mine looks exactly like this if I haven't cleaned the lens in a while. All the saltwater in the atmosphere here depositing junk on the lens.
First try different camera apps..If you see the exact light spots in different camera pictures..I would pull back case off there's 9 little screws..and use a wedge tool atounf the chrome casing and the glass..pulls off easy..abd clean the back of the lens..very easy to do..sometimes dust gets in there from the speaker and blows around...

[Q] White outline in pitch black images, faulty screen?

Hey guys, I've never posted here, I mostly just lurk and try to learn things.
My question is a bit difficult to explain but I'll try my best. Do me a favor and take a photo while completely covering the camera lens, then view the photo in the gallery. Make sure youre in a dark room and viewing the photo in full screen, wait a second for the back and task manager buttons to turn off as well.
Is your picture completely black or are the outside edges and corners fuzzy and white almost?
My previous phones are Galaxy S1, 2, 3 and 4 along with the Note 3 (which I miss :/ ) never had a problem like this, I do believe some GS2s had a similar problem with the screen being spotty in black images.
thanks.

Hello there, I did a test for you on mine, when i was in my room with my lights on but completely covered the lens and mine came out fuzzy. It seems that the s5 camera is very powerful picking up the slightest bit of light !
Then I turned off the lights in my room and did the same test, this time it was pitch black.
Did you try turning all your lights off in your room?
Thanks for your input, my initial test was in a room with the lights off. Looks so bad :/

I noticed that with my camera too. The exact same thing happens to me too when I cover the camera, in both lighted and unlighted rooms. But I'm pretty sure it's normal. When your ISO is on auto, you'll notice that the camera turns up the ISO past what you can manually set it at (800). So since they're bumping up the ISO so high (probably ~1600 in dark areas), there's going to be considerable amounts of noise, even with very low light.
You can see for yourself that if you compare auto ISO and ISO 800 in a dark room, the latter will be much more pitch black like you expect it to be.

Anyone else with very bad lens flare?

https://www.dropbox.com/sc/w3aflekki0thqhj/AABqSYnVucDo-QVQeqYJeb2Ba
Anyone have this wonderful issue? I used my note 8 in the exact manner and no issues. No case on the s9+ or anything that could cause this besides a possible hardware issue or I received a lemon. Please check out your camera's and let me know plz. I hope it's just my phone
Yes! Under certain angels it's unbearable. Even had to check if I left some of the film on there, nope..

Thanks for the response. I went back outside to take more pics and I noticed the camera module was very reflective. It was like i was reflecting light with a little mirror. I grabbed my note 8 to see how that module's reflected light. At first i barely saw the reflection. Then i had to really put the phone at a major angle to get a brighter reflection. I think the camera module's aren't positioned correctly or designed correctly to avoid recieving the sun's rays in an improper way which then produces these crazy sun rays in the pics. My pics were taken mid day so the sun was kinda just past it's peak height. I took more pics later on with the sun lower and couldn't recreate the crazy flare. This is a deal breaker for me. Do you plan on keeping yours? I called Samsung and they weren't any help. They told me to return the phone and order another if I wanted.. this sucks
Damn. That's some crazy lens flare. I'm heading to Hawaii next week, and I'll be taking my S9+ (if it shows up on time). I hope the lens flare isn't going to ruin all my pics.
My Note 8 does it at certain angles, I just use my hand as a lens hood on the side that the sun is coming from.

Yeah, it's bad. Just communicated with Samsung Support on Twitter and they blamed the dual aperture. Suggested I try different angles and tap to focus. Smh. Guess enough people will have to complain before they realize there's an issue.

lol Well, if it is the dual aperture, it's a design/manufacturer flaw.
They basically just fed you the "You're holding it wrong" Apple reply, lol.
Thought it was a rainbow. How did you get it to show? As none of my pics have that but it hasn't been sunny here
Yeah the 1st photo I took outside had lens flare. I'll deal. I got the phone for the stereo speakers and speed. Not the camera.
While it may not eliminate all of it, you do have something on the outer glass covering the lens. It needs to be cleaned with a lens pen. That's what's causing those little o shaped artifacts. Because of the tiny aperture and very wide (F 1.5), these objective element must be kept optically clean as if it were a laser optic! That's exceedingly difficult since its exposed. My suggestion is to purchase a lens pen and keep it with you if the best quality pictures are important. One can really see this at night when capturing dark scenes with bright pinpoint sources such as headlamps and streetlights, etc.
My biggest issue with camera phones (they all have it!) is the internal reflections producing ghost images. It's really apparent at events (i.e. concerts) with multiple bright points of light. Bathes the image in little blue-green dots everywhere.

The pic with the circled artifacts was the first pic I took. The lens was clean toothe best of my knowledge. The following pics didn't have and of those artifacts pop up. Nevertheless, I'm concerned that there is a design flaw. I've owned many phones and have never had such an issue with taking pics with the sun. I was tweeting Samsung support and said the light penetrating into the lens was the reason for the terrible pics. Idk.. the phone is very new so we'll see how many do or don't come forward with this issue. All I know is the afternoon sun was just at the right height to cause the angle that the camera didn't agree with.
It's possible as with wider apertures and very bright out of frame light sources striking the periphery of the aperture you will see this. This can't be avoided even with pro gear hence the use of bulky hoods.
The idea of a two step iris, even in its rudimentary form, is a new frontier for mobile devices and this could be a glaring limitation if not annoying. Just as when driving one uses a visor or their hand, you may have to improvise and provide some shading to limit these artifacts.
Used hand as a shield
Well, took some more pics and the results are terrible. I even had it in video. I used my hand as a shield and away went the lens flare. I even rotated the phone to were the modules were on the opposite side as I normally use the phone during picture and video taking. I think that made it worse. I'm just disgusted.
Another example of me shielding the sun.
Sorry but they were flipped during the upload process.

Thank you for sharing. The speakers and speed are great! I messed with the phone before it was released and thought the speakers were ok. When trying them when I recieved the phone i was very impressed. I take a ton of pics so I don't think I can tolerate this camera issue.
