Hi Guys,
I am woring on an image processing project on the ATT tilt and I needed some vital information on the camera
1) Manufacturer and model
2) Focal Length of camera
and has a fix been found to disable the autofocus as that i causing some problems in the image processing.
Does anybody have any registry tweaks that can be used for the camera to speedup the autofoucs/disable it.
Any help would be appreciated.
Thanks
There was a previous thread showing that you can speed up the frame rate with a simple 3 step process. It does work but it has to be done every time you start the camera up and it removes the cameras ability to autoadjust light settings. Not sure how it effects focus.
1. Start up the camera.
2. Put the phone to sleep (just click power button)
3. Cover the camera lens with your palm or point it towards a dark place ( i have found a SMALL amount of light help)
4. With camera still in the dark, wake the phone back up.
You will notice the camera stutters for a second and then the frame rate jumps up incredibly. You are almost seing real time action (half second delay). The side effect is the lack of focus and light detection. Not sure if this helps you but its cool to try anyway. I would not that it does capture video with increased video and sound sample rates.

So i updated to the my tilt to Duttys Apr 1st rom, and since then, my camera is very slow on the FPS. I reinstalled the Camera 5.0.4.2915 fix, but no luck. So in reading, i found that if i turned on the camera, then hit the power button, then placed my hand over the camera lense, then hit the power button, i get much better FPS. But after i turn off the camera, the FPS goes back to very poor (so where everything is blurry). Does anyone have any ideas for a fix for this?
Thanks
This has been around for ages. All it does is stop the cameras light meter working, so it is locked to one exposure. It means you might get a dark picture, rather than a blurry one.
I wonder if the root of the problem is that the camera doesn't support a variable ISO speed? On my k750i, as it got darker the camera boosted the ISO resulting in grainier (but lighter) images. Looks like the our TYTN IIs might be locked to a single ISO speed, with only adjustments to the exposure time being made to compensate for darkness.
Is there a way of getting good performance from the video on the TyTN II, when there is "low light"?
For example, if I am outdoors during the day, video records brilliantly... very smooth. If I record in the house at night with the lights on, video recording is very very jittery (but sound is perfect).
I have found that if I gradually aim the camera towards the lights the video recording gets gradually better the more light that gets in to the camera.
Thats a pretty funny question.
shutter speed ?
I would imagine the camera is combining frames due to the lack of data from the low light, effectively reducing the frames per second but providing at least a viewable picture. This is probably by design and the alternative would be a great frames per second in low light but entirely useless dark video.
Adjusting the contrast in image properties allowed me to see more in a dark room, but the motion is still awful compared to daylight video. I don't believe there is any way around it, other than turn on a light. Maybe someone does know a way to just slightly tweak it to accomplish a better a compromise, though. Anyone?
daaaayyyuuumm dude...search!!!

Anyone else having issues with the camera not taking crisp photos?
I came from a S3 and once you touched the screen to focus and then hit the photo button it would take sharp pictures all the time, on the S5 I have went thru every setting possible trying to see of one will help it take a clear picture and as of yet have failed every time.
Sitting in the living room lit with sunlight I tried to take a pic of the living room, came out blurry (yes the plastic film is off of the camera). out of 5 photos maybe 2 come out clear. Last night at the basketball game I had the same issues, pictures of us taken by other people required multiple shots to get one that came out clear, shots we took in the arena when it was lit up well were hard to get to come out in focus.
Anyone else seeing these issues on the S5?
Turn off picture stabilization future in your camera.
Swiping from dark side of Galaxy S5.

This. I'll explain. the higher the ISO the faster the shutter speed at the expense of photo quality. in traditional film cameras higher speed films (ISO) came out very grainy and loss of detail. It's used a lot in dark, low light situations because as you know the slower the shutter speed, the more chance of blur.
image stabilization in smartphones has at least some to do with shortening that shutter speed by ramping up the ISO, leading to loss of detail. aperture / shutter speed / iso are the three things that are correlated, our cameras have a set aperture. when you take pics outdoors on a bright day, the shutter doesn't have to be open long, and the ISO is taken down to 100, so that is why you have amazing crisp clear pictures.
at night, take of image stabilization, set the ISO to 100-200-400, and have a VERY steady hand. when you try all 3 ISO levels, you'll notice it will take longer for the shutter to close, however if you have a tripod or set it on a table, your picture will look very clear. clearer than iso 400, 800, etc.
the benefit is at higher ISO, in low light settings the shutter will be faster so less chance of blur
I don't have the image stabilization turned on, it takes to long to use it and even when I did try it out the photos it produced were blurry as well.
I am pretty camera savvy as I have a nice DSLR, I have tried different metering options and messed with the ISO. No change in settings produces a clear picture, beginning to wonder if I have a defective camera system in the phone. I noticed this morning that the camera module is set in the phone crooked as well.

I get very sharp shots in good light. I'd say it is hard to get one out of focus in good light. I'm seeing pretty decent performance in low light (for a camera phone). If you are getting poor focus in good light, you may have a defecting camera.
What shutter speeds are you getting for the ones that are out of focus? Because of the camera's limitations in aperture and ISO, it is easy to get shutter speeds in the 1/15 second range. Obviously anything moving in the picture is going to have motion blur, on any camera. Only way to get around that is to increase light (e.g., use flash).
Here are a couple things to try (if it is not motion blur of subjects):
- Turn on tap to take picture, and keep the phone as still as possible. I find that with this set, I have to do less handling of the phone and can keep it more stable
- Picture stabilization helps a bit. It increases the ISO a bit, and does some image processing. It appears to be doing some sort multi-frame processing (comparing/combining multiple frames to yield a better shot). Seems to help more with camera shake blur than it does with subject motion blur.
I need some insight into the P10 camera. In auto, the rear camera seems to incorrectly read exposure so I find it overexposures the screen in bright sunlight or situations of high contrast. It's very hard taking a picture when a slight tilt of the phone makes it switch from dark to light in an instant. Just as bad in selfie mode.
Is this normal? Is there anyway to adjust it?
I find it mystifying as it's incapable of taking a simple pic in an ordinary scenario which most other good phones on the market are capable of doing by default.
Of course there is manual mode where you can adjust the EV but it should be able to do this automatically.
When you hold you finger on screen you can change exposure I think (a circled sun icon appears) ? You move it with finger still on screen to see differences.
Recently, I've noticed the Note 8 camera tends to overexpose the background light in photos by default (that is when you tap on the screen to focus on a location and it adjusts light automatically). The pictures are amazingly sharp and high quality, but they seem a bit fake due to this light overexposure. On the other hand, when I manually adjust the light, the pictures tend to look more realistic of the natural situation.
So does the camera just overexpose by default? Or is this normal for all cameras? I'm using all default settings and auto mode.
For comparison, and better understanding of my question, see the two photos.
Touch to focus work similar in every other phone. Get focus and light settings only on touched object. Background always become over or under exposed in depending the darkness of the focused object.
For solve that use camera soft button. In this case focus and light will be average for whole pic.
