My new HTC One (bought it in Australia) sometimes makes a high pitched scream screech sound when I use the Touch to Capture feature when taking photos. If I use the normal shutter icon (with the shutter sound off) it doesn't make the high pitched sound at all. If I reboot the phone or kill the camera app (dragging the camera off from the multi-task window) then it is fine again for x number of photos.
My best guess is that it has something to do with the Optical Image Stabilization doing something funny? That is how it moves the CCD so as to counter camera shake. Is it possible that it has to focus faster when you touch the screen? It is still taking amazing sharp clear photos.

Hi,
I'v noticed some potential problems with my camera, and I have a few other questions too to help make me get the best out of the camera. This is all using 2.1 ROM and SE camera app.
1.When my camera autofocuses, sometimes it emits a light 'clicking' noise from the inside. I'm not sure if this is only me, and I want to make sure it's not an oddity.
And about the autofocus, it's terrible sometimes. The autofocus bracket turns red quite a lot, meaning it's not got a lock on focus and sometimes it shoots with the red bracket meaning it's not focused (this happens on touch to shoot mode). Sometimes, it says its focused on something when it isn't. This usually happens when close up, like 15-20 cm away from the object.
2.Image stabilization- is it good or bad? I've noticed camera shots are a bit more grainy with image stabilization on and it takes a bit of time to process the shots too. Does image stabilization make any noticable impact on quality of photos?
3. Metering:Center, spot vs average. Which is the best?
4.How exactly does Macro mode work? I've not seen any noticable difference of pictures using it and normal mode.
5.Is there a way to remove the jpeg compression, or at least reduce it? I think photos could be MUCH better if sony hadn't implemented that.
So those are my questions. Thanks for any help on shedding light to the issue(s)
1. I noticed that click on K750 also, and I think that autofocusing mechanism. And yeah x10 has terrible autofocus, especcialy on macros
2. Image stabilisation is used mostly in night/low light images and it compesates hands shaking when holding camera. It does not do wonders, but it is much easier to take night photo with stabilisation on. Also when its on, pictures are not sharp as they are without stabiliastion.
3. generaly:
average - for landscapes and well lit shots
centre - portaits
spot - macros
4. you cannont autofocus on macro distance(10cm or so) if macro or auto mode isnt turned on
5. only way to reduce JPEG compression is to use vignette aplication with super fine quality (check Camera 360 app also)
one major tip, play with EV always and youll get much better results
cheers mate

28spawn's modded stock camera for 2.1 has somewhat less compressed jpegs and some other improvements. It's in the Themes & Apps section.
I have had a couple of autofocus camera phones now and they have all done the clicking noise during the focusing, so I am guessing that is completely normal. Image stabilization does make the pictures turn out a lot worse, try to avoid using that. And as hibiskus said, the EV controls make a world of difference! Check out this link http://www.digital-photo-secrets.com...xposure-value/ It has some useful information on the EV controls.
Does anyone else hear a clicking sound from the autofocus mechanism when using the camera? Whenever the camera focuses, there is at least one click. Occurs a lot with the video camera when panning which requires the autofocus to constantly refocus. It's not loud, but annoying.
This is not an issue when actually recording video as it appears that autofocus is not active while recording.
I don't have my Rezound yet, but my Desire's camera clicks once in a while when it is shutting down.
yes, that's just the lens moving around. it makes noise.
attaches pic shows a carpet. it looks blury and kind of filtered - but i haven't selected one. all settings on "0", highest resolution and so on.
anyone has a hint why?
It seems the HOX+ has strong noise filters... that means if you take a pic in very dim light it will not show much noise but it will look a bit like a painting
both (noise and strong noise filters) is not good for picture quality, so your pic would be nothing in any matter... take a pic in good light, there the quality is very good for a phone... And I don't know how much your sample picture has been magnified....
btw: why did you take a pic of your carpet??
thanks for the answer. i took the pic in dimmed light, max zoom. even faces are pixeled like that - but i don't won't to paste my wife here
how can i disable the noise filter? i like most features of the camera - but good light isn't always possible.

Zoom is just digital zoom, so if you take a picture at widest setting and copy the inner part out of it on your computer does the same... digital zoom is crap, but only way today on smartphones...
you can't do anything about the noise filter. try another photo app, maybe it handles pictures in a different way - didn't test it until today so I don't know where the processing does take it's part...
i had google camera 4.2 on my desire hd - what was a very fine app. but my hox+ isn't rooted yet (2 days old) and i like the fast picture option.
thanks for your hints
still not lucky with the advertised "best camera" - qualitiy is so pixelated :/ on my desire hd all was nice and clear.
is this a software or a hardware "bug"?
comparing "normal" with "camera pro" i have 990kb vs. 4.5mb
normal:
pro-camera:
took max. resolution, no filters or other changes.
maybe someone can show a pic from his hox+
it's frustrating.
thanks for your help
regards,

Ok, I wrote also in other threads but haven't been asnwered at all. I have a Snapdragon 435 device from Xiaomi and a high end sensor of the front camera! An OV5675 Omnivision 5 mpx. My problem is devided into two parts. The main part is that I can take extremely high quality pictures with Google Camera, even if the preview image is a very bad one even with camera2api activated, blury and low on framerate ( abou10-12 if high brighness and smoother if I lower the lights of the sensor when simply opening the camera app and not taking pics ) . When it comes to make a video call, in any app like Duo, Whatsapp etc .... The quality of the preview AND of the call is awful! It is vey blury and low fps, just like in the cheap stock camera viewfinder ( preview mode) . I want to understand, is this limited by the software or it is because the hardware is low end?
I will tell you why I am so concerned of this question - When I open the camera app and switch to the video, I get a very cool FPS on the preview ( not when recording, just the preview viewfinder ) and the image is very clear, not blury. When I switch back to the photo camera, the fps of the preview goes down and the image becomes blury and awful ( even in the Google Camera, even in the stock camera) but when I take a picture in any of these, I get clear images in both.
So! Let's go to the point - The quality of the video call in any of the apps, is the same as in the camera preview mode of the photo mode ( in the viewfinder ). How do I comunicate to these 3rd party apps to use the camera mode/ sensor of the video preview mode? How to make the image durinng a video call be clear and not blury like in the photo preview state? The app code should be edited or the rom?
What I mean is ... let's say I am using Skype for a video call. At the moment of connecting to the camera, what is the way it does this? What code is used? What part of the camera is accessed? When I open the camera app of the device, and trigger between photo/video - I get 2 absolutely different images of the preview ( the viewfinder ). The photo preview is on a low fps, if there is enough light, if I reduce the brighness, the preview fps gets smoother.
But when I swicth to video , I get a very clear image, with a high fps, little noisy and clear. Though, the preview of the photo camera is blury ( noise reducted ) and low on frame rate.
So, the calls in Skype has the exactly same image type like the photo preview, blury and fps low.
Is there any way to drive Skype using the camera type of the video viewfinder? It is a very huge difference in quality, and it is very weird, video calling apps use the worst part of the camera, when there's actually obvious the sensor is a high end one, showing it actually can offer a good quality of the image ( while in video mode ).
Please help, I want to try to develope something related to this. How does an app choose how to use phone's camera?
