OIS... it's the optical image stabilization feature to allow for less motion blur in low light photos and less shaky video. :good:

Is there a way to disable it? 1st time LG user..before this samsung s3
Um... not sure how to disable it... maybe I am not understanding the problem?
Generally OIS is thought of as a desirable feature...

The problem is that when i already focus to an object, but the lens is still moving. Is it normal?
The object is in non moving motion. But lens still moving..like a gyroscope not in balance..
In my camera test,it stated fail for my gyroscope test..any chance to calibrate it?
edit; already found how to calibrate it, but during system test found my laser detect test is fail...how to do?
The subject may not be moving but the camera is compensating for the phone being moved.
Are you using a tripod? Are you experiencing poor camera performance? Why are you looking at the lens while focusing?
I'm sorry, I don't know how to do those calibrations, but there may be certain external requirements to pass/calibrate them. I don't understand what problem you are experiencing or what you are trying to correct... I am guessing your using the hidden menu tests?

Hi,
I have searched from all over the web app that could change camera's exposure time. I like to take good nigh photos, or anyway as good as it's possible with mobilephone camera, but like in mine HTC Desire exposure time is way too short.
I have tried many of those camera apps from market, like camera 360, but non of them can adjust shutter speed/exposure way I wanted. Say, I want a long exposure for night photo. For example I would like input exposure value to app, so that it would expose photo for 10 seconds.
So, do anyone know app to change exposure/shutter speed?
And my Desire is not rooted and I'm currently not planning to do so.
Would love to know about this, too; any ideas for this?
Sign me up for this as well.
Long exposures would be great. Would need some sort of remote shutter release or time delay ideally and a mounting system, tripod fashion.
Problem is - you'd also need a mount or tripod of some sort to hold the camera still enought to make long exposures work
I don't know about the rest of you but I can only handhold steady my DSLR down to about 1/80th of a second

I have managed 1/15 and 1/8 (the latter very rarely) handheld with my Pentax (image stabilisation built into body FTW), but yeah, you would have to use a tripod or to prop it up and have a timed shutter release for the phone. This isn't a problem as such, even just being able to specify the aperture would be welcome.
Well a mount can be anything...jumper, phone leaned against a wall. Would be awesome for cityscapes and such. Anyone found anything which indicates this is possible with a software patch? New to android and just tearing through my first rom package
Exactly, it doesn't have to be anything serious, just lean it against a beer for example.
I can't see a reason why you couldn't manually control everything, I can control ISO, metering, etc on my SGS, adding aperture and shutter shouldn't be outside the realm of possibility.
Had a look around as a noob to Android dev/roms etc. and I don't think it's possible to control the hardware to that level :/
Would love to be corrected on this, though!
I don't have the SDK installed anymore, can someone test what camera.getParameters gives on a device?
This would be great, the DX has a nice camera but additional lens control would put the icing on the cake

I can handhold my Leica down to 1/15. You need more practice (a lot of it).

Not to be too big a jerk here, but if you can only hand-hold an SLR steady, any SLR, at 1/80 or faster then I'm sorry to say that you may have a serious case of parkinson's, or are the most ADHD person who ever picked up a camera.
1/60 is recognized as the speed at which regular hand-held motion is mitigated, and unless you're actively moving the camera (or standing on top of a paint-mixer), you will not get camera-shake at that speed. Most photographers are able to hand-hold, and get a shake-free shot, down to about 1/8 on a good day.

What was the rest of the code? and did you try this on actual hardware or the emulator?
I will try to code an app for that. Plus FFC Support...
but you'll have to wait until I'm back from Japan
EDIT: It's not possible to really influence the shutter-speed or the aperture, because it is non-existent in the hardware, but there can be an interpolation of both values that are calculated from ISO settings and exposure calculation. It won't be perfect in any way, but it might be possible to do something similar... probably it is possible to gain more control via the ndk or by "cheating".
Thanks Flokey!
Does anyone knows if there is such a program?
I don't think a long shutter on todays camera phones would be useful as the sensor noise would be crazy bad.

Whenever I am recording video it seems to be constantly going in and out of focus. Any idea what I'm doing wrong?

You couldn't ask both your questions in one thread? Post some examples.
I'm not sure what else to say besides it oscillates constantly, meaning fractions of a second.

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.

Manual focus would also be good when taking pics up real close. My cam will get in focus but the autofocus adjusts it, and its no longer in focus, this only happens up really close...lmk if you find one.

Yes, but it doesn't work at like 4 inches. But the phone is capable of focusing there, because in the middle of the auto focusing its clear for a second, but when it finally "focuses" its out of focus. All of my smart phones have done that.....also sometimes clear water throws off the autofocus.

Use your finger and focus on the specific item on the screen, have your scene set to auto, that seems to work for me.

And when you do get it focused, it focuses on something else.
So anyone tried camera 360 as yet?
Even with camera 360, on some shots I see it focus perfectly, and then it loses the focus.

Cool app, allows a lot of extra settings(like bracketing, so you can manually create HDR thru pc apps or photoshop, better quality) - but still no manual focus(check instructions here http://www.camera.flavionet.com/tutorials/camera_manual.php)
A cool app, but I for one am still wanting to find an app that allows manual focus while still doing high quality - I don't want an app that only takes lower resolution pictures..

I'm just not sure an app like that exists, based on design (of our camera and its image sensor) it seems that a manually focusing camera app would only be imitating the actual function of manual focus.
This option in fv-5 is the closest I've seen yet, though its not even similiar to true MF
" Infinity. Set the focus to infinity. Tapping on the screen always result in focus confirmation and AF is not triggered."

A manual focus app doesn't exist because, simply, the functions to support it do not exist.
Look on developer.android.com and you will only find autofocus functions for adjusting camera focus, like:
public final void autoFocus (Camera.AutoFocusCallback cb)
public final void cancelAutoFocus ()
public void setAutoFocusMoveCallback (Camera.AutoFocusMoveCallback cb)
Just curious why you would want to use a phone to skating? Invest a couple hundred bucks and make good quality ish.

Probably the only good quality camera they have/can afford. The camera on this phone is better than any digital camera I've bought yet. Lol also, I know after buying this phone, I was broke for awhile. I didn't have an upgrade and bought it out right.
But it is frustrating as hell when I get a picture I want to take, it focuses perfectly on the object, just to auto focus and lose it. Like, ill try and focus on an object, and during the auto focus I see it go clear for a second just to skip over this perfect shot and blur the image instead.

A few months back I upgraded my phone from op2 to LG g5 H860.
So, I've been playing around with my phone and I noticed that my camera pictures are grainy. Seems like pictures taken on a 5mp (or lesser) camera.
I took pictures with my camera (all default settings and auto mode) without any zoom and after capturing I tried to zoom in into the picture, like 20% zoom to notice that they are very noisy. I'm not so good at photography, so I never bothered to check this kind of stuff with my other phones before.
I have taken pictures with both rear and front cameras and they both look very noisy. Like water color painted pictures. I'm not sure if I'm putting the right words here but I think you get what I am talking about. I am adding a sample attachment.
Can someone tell me if this is normal or am I missing something here or if there's some problem with my phone itself?
I am already frustrated that I can't unlock my bootloader and I hope this wouldn't add more to it.
Do you tried clear the lenses?

Yes I did. But that doesn't seem to be like a problem with dirty lenses?
Man, I had the same exact problem.. buy new lens.
Try manual mode and turn down the iso speed. Sometimes higher iso speeds produce heavy grain. See if that helps any.

I guess it's the only solution. Thanks.
I had this problem as well. I turned off HDR under settings and that fixed it.
Anyone else notice a rattle in the camera when the screen is off or when not using the camera app? It's noticeable when you gently shake the phone.
It goes away when you open the camera outside of macro mode. Just making sure I'm not the only one.
Yeah, me too, but that's normal, because cameras have optical stabilization，You can find help in the Settings, which will explain the device in detail
