Source of camera speed? Hardware? ICS? - Samsung Galaxy Nexus

I currently have an LG Nitro HD and the camera has HORRIBLE shutter lag (requires about 6 seconds from 1 shot to the next). It's a good camera, but it ain't gonna get the job done when I see Bigfoot and need to snap a quick shot for proof!
I went to a Verizon store today and tested out the GNex's "0 shutter lag" and true to the hype it's indeed spontaneous!...At the cost of overriding focus lock before capture though!
Even so, there's apparently some buffering/caching going on from shot to shot and I'm wondering how that's done... Is there some kind of functionality coolness going on with the GNex's camera, or maybe it's due to some new camera methods available in the ICS OS itself?
Anyone have some technical insight to this?
thanks.

i have no technical knowledge on it, but from what i've read, it's a combination of both ICS and the hardware itself.
so i think that ICS on other hardware may speed it up, but to get instant you need to have a camera thats capable of it.

Jello effect w/ video recording. Why hasn't this got more attention?

(can't post links still)
youtube[dot]com/watch?v=gymA26jqtTQ
It's really the only thing that's stopping me from buying the Galaxy Nexus. In my opinion the Galaxy Nexus can't take video if that's what it's producing. Anyone here a photography master of sorts that can shed some light on this issue?
Through my research I've found that the jello effect caused by a rolling shutter can be fixed in post production, but is something like this fixable via software/firmware on the phone?
What's going on? It's a bit shocking that nobody is concerned about this issue.
are you serious? "what's going on?"
it's quite obviously image stabilisation.
The sensor basically just relays data, OMAP camera hardware interface process it (stabilisation etc...) and Android presents, maybe tweaks it a bit and saves it.
So an eventual "fix" would be in OMAP firmware, not Android right?

I don't know, but there is an option in Google Talk to change image stabilisation effect.
I have the same thing,but I think that it is image stabilization.
I've just replicated this issue and must say.. I'm totally not bothered! The image stabilisation is actually pretty good and the ony time i can make it do this is if I jiggle the camera... unless youre planning on trying to mock up an earthquake effect, I dont see this being an action you would do. In fact, due to the good image stabilisation, its pretty hard to do this jiggle accidentally, you must be quite determined to create this "jelly" effect (I'm in the UK, hence I get a jelly effect, not jello )

If you don't want to read, its because it uses a CMOS sensor. Affects cell phones and DSLRs alike. Hardware related.

May I ask what makes you so sure?
The video effect shown in the original post and in others if you look, mirrors exactly that of the "jello effect" caused by a rolling shutter, i.e. the sensor, more importantly, CMOS sensors. From what I've found: all cameras, even professional DSLR's have this "jello effect" caused by rolling shutters on CMOS sensors. The only, and most common fix I've found is to edit the video in post production.
It's not quite obviously image stabilization considering how this issue is reproduced in the exact same scenario a rolling shutter w/ CMOS sensor would to create the jello effect. Otherwise the issue would occur all the time and not only when panning quickly. The video below should explain.
youtube[dot]com/watch?feature=player_detailpage&v=ITkLwVgxo98#t=61s
This may not be the best example, but it should show you what I am talking about. Others like this can be found by doing a simple Google or YouTube search.
The problem is oscillik is both a) incorrect, and b) an asshole. A dangerous combination to be sure!

LOL, funny stuff.
I know what rolling shutter effect on CMOS based cameras is. This looks more excessive than rolling shutter, and looks more like image stabilisation.
People really need to stop thinking that SmartPhones are the end all be all. Unless a phone is specifically dedicated for a camera as it's main feature, then of course people should be concerned.
People here really plan on shooting lots of hd video with their phone? If quality really matters a dedicated camera would be better served...from what I can see this is pretty trivial. Then again, the only thing I take video of is dyno runs and fun in bed...
Again not hardware involved!!!

Awesome! Glad to see this fixed, and nice find by the way. An update to the default camera app will come I'm sure. Until then this essentially fixed the problem, whatever it was, if image stabilization, I stand corrected.
it is image stabilisation, as has been proven by the fact that using another application gets rid of it.

Here's a 1080p video I took at a Football stadium. Big game, I luckily shot the only goal at Arsenal Vs Man City on Tuesday.
http://www.youtube.com/watch?v=TxsdD7iPpnM&feature=g-all
I tried using the LGCamera app mentioned in the YouTube post but it crashes on launch. Has anyone else had any luck?
GSM version running 4.01.
I use 720p because of the 30fps. 1080p is 24fps on the Gnex.
No thanks to 24fps.
That explains why image stabilization is having a hard time at stabilizing the image at that resolution at the frame rate.
I think image stabilization works best at higher frame rates.
My two cents.
Having said that, I do feel rolling shutter is a underrated issue with smart phones and point and shot. I would much rather have 720p without rolling shutter than 1080p with in.
I think post processing like deshaker is some cool stuff too. There are some really cool videos on youtube.
http://www.youtube.com/watch?v=GaPNf2Rk4qQ

If they could do deshaking in realtime and eliminate rolling shutting... That would be cool. Some day.

[Q] New to Glide - Questions

Sorry - I ran a couple of searches and skimmed a half dozen pages in each of the sub-sections - so apologies if I didn't find something obvious...
I like the Glide, have rooted it successfully and am more or less happy with it but for a couple of things. First, the camera doesn't seem as sharp as my Sony Xperia Ray, which is also an 8 mp and not even as good as the 5 mp on the Behold II. I have several camera apps, so I'll try out some of them - could be operator error, I guess. I do use auto settings most of the time - is there something I could set manually to see if that helps?
Also, the audio volume on calls seems fine but not so great on audio books or video files. Even with headphones. Are there any options - media players that can take it to 11 or maybe custom roms that might help?
Finally, it's been forever since I've had an AT&T phone - is there a list of safe to freeze/uninstall programs? I'd rather not flash a custom rom right unless I have to, since this is my main phone but I'd like to get the AT&T specific stuff out, since I'm using Straight Talk.
Thanks!

1. Megapixels do not indicate image quality. It simply means how big you can blow up an image without sacrificing clarity. There's a lot of factors that play into image quality, such as the sensor, f stop, aperture, lighting, etc. And yes, I've seen lower MP cameras produce better pictures than higher MP cameras. I suggest you research more on what makes a camera tick if you still have questions, or feel free to post here. Try messing around with the settings, if that helps... But don't expect crap pictures to look amazing with the flick of a setting.
2. Try any of the equalizers you can find online. Most people seem to like Beats, Volume+. There are many to choose from, including the ones already built into some players, such as the stock player. I personally like the DSP manager included with CM roms. It has a good amount of options, and can make even the worst headphones sound halfway decent.

Also numbering - for consistency...
1. Are you saying the Glide has a crap camera? I thought it was the same as the S2 and on gsmarena, the samples look better than the Ray. I guess I assumed that Samsung would have improved the camera between the 5 and 8 mp - but the Glide output seems very noisy when I look at the pictures on my PC. I care quite a lot about the camera quality and I know from past phones that software updates can often make a huge difference.
2. Thanks for the tips. Hopefully that will help the audio but you seem to infer that system wide (like for video) I need an updated rom?
3. Saw that post (searched for bloatware but only read the posts that seemed specific) and it links to a post about a deodexed rom zip file.
4. Thanks!
I hope I didn't sound too negative - I do like the Usb OTG and having a keyboard again. And I think the Glide meets the Mobile Ubuntu basic specs, so that might be interesting, too. I can even deal with the sound quality but the camera... well, we'll see, I guess.
I did buy Volume+ and it made a huge difference. Not with every video player but enough to make it worthwhile.

The captivate glide has a solid camera. Not the best, but also not the worst. Best camera phone I've had was my old MyTouch 4G Slide. It took better pictures than a GS3, and just about any other phone out there (on par with an iPhone 5). If you're rooted, just back up your phone and start deleting stuff. If it affects your daily routine, or you need something back, you can always restore. Either that or try a custom rom. But you can safely remove all the ATT branded apps, in addition to some other apps preinstalled. If you see what comes on an AOSP rom, you will get a better idea of what's necessary and what isn't.

Captivate Glide was built for businessmen, so you can't ask for a good camera or voice quality as the physical keyboard takes alot of spaces, but they are not crap, you can tweak the images with pixlr or line camera, worth a try

I concur, the call quality is surprisingly bad. Voices sound muffled overall
I used to think that glide has a crap camera and i tried various camera apps to have an improvement. Some xda users just let me focus on how to use it correctly and they suggested me to simply use the stock camera app being careful and focusing on staying stable and use the focus function (it is to say, tapping on the screen to make the frame get green).
I have to say that after a few tries it actually worked. I used to think that camera was poor but i can get very good pics now, and they're good when i download them on pc as well. It's all up to you and your stillness in taking the photo.
Hope it helps.

Strange, my calling sound is normal, maybe this is because of the firmware or the network
After a month or so with the Glide, I've compensated for some of the problems with the Volume+ and Wake Lock, which keeps it from dying at times, especially overnight and draining the battery. I still have issues with staying connected to wifi, which the various keep-alive programs I've downloaded so far haven't helped much (miss having a radio, internet radio with wifi issues isn't fun).
The camera seems to be helped a lot when I use the various scene modes, which I rarely used on other phones (other than macro). Not sure why the automatic is so awful but if I pick the right scene, things turn out much better. I already owned Pro HDR Camera, so when it took better pictures than the automatic I knew it was possible, at least.
The Glide was always going to be an interim phone, unless the Ubuntu thing works out, so I'm okay with it now that things are stabilized. It doesn't say much for Samsung's quality that there are so many issues, but with the keyboard being practically extinct, they have a built-in market.

Camera APKs and quality

I have come to a point where I don't remember the camera being so low quality on the Optimus G (maybe due to the time that's passed by and upgrades on newer phones) but I'm curious to know if different camera apks like the LG signed aosp one is better or worse than lets say the G2 camera or google play edition. I know software has to do with improving the quality of the shots to a certain point but again I haven't seen anything for 4.4.X roms. Anyone that can help me out here.
I use camera FV-5 no matter what when it comes to needing great pictures. The stock Google camera also is great 80% of the time. Those two seem to be the best IMO. remember to wipe off the camera glass before pictures also, simple but some people forget to. Also scratches on it will reduce the quality. ANYWAYS, those two cameras + epics mod = definitely acceptable.

Anyone knows how to get the Stock G4 Camera app?

Hello!
Yesterday I flashed CyanogenMod on my G4 H815 and just before the phone rebooted, I realized that I won't have the mega-awesome Camera app from LG. So does anyone know if there is any apk or any way to get it? To mention, I didn't backup my device because... because.
Thank you!
Probably won't work even if you get the apk, since most OEM specific apps need OEM specific framework to run. I think the only way to have it working on CM would be to port it. But why would you want that anyway? The image quality won't really change. It's not that much dependant on the app but rather the drivers running the camera.

It's not necessary the image quality, but the flexibility you have with that app (manual focus, iso, exposure time, etc.). I hope there is a way to use that app. While I was searching for it I found that there is the G4 Camera app ported for G3, so I am thinking that there could be the original app somewhere..
Thanks!
It's not possible right now. There have been efforts to port it, but nothing has come out of it yet. There are however other apps that are pretty good. And the CM stock camera app only misses the HDR and Manual settings. The quality otherwise is similar

there are 3rd party apps that should work for manual setting but your max shutter won't exceed 0.7s. This is the already the case with the stock firmware and 3rd party camera apps.
There is something called night shot which the G4 resorts to very often especially with the front camera. that will be gone. Selfies ain't going to be as good. it's also used for the rear in lower light. Though a longer exposure will produce better images. night shot is a convenience when you don't want to set up on a tripod.

How can you tell ?
it requires a side by side in full resolution with 2 G4's one with stock & CM under varying lighting. Lots of comparisons like that.
How good is the Cm camera in auto ? that's one of the strengths of the stock G4 camera.
Does the Cm camera make use of the colour sensor at all.
Except for the 30s exposure there is nothing special about that app, just use Proshot and you will be far better, cancel noise reduction make dngs and you have better shots

I can tell because I have seen photos from both cameras (on the computer). And if you really need 2 separate G4s under the same conditions side by side to tell the difference then there is not much difference. It's the audio bitrate debate all over again.
I am not saying it's as good as with stock but similar in most situations. I miss the HDR feature because it helps in low light situations.

Can you post links to examples of photos taken with cm camera ?
saw a few in the g4 community but the max resolution was just 2.4MP, need to be full resolution.
The low light shots on auto were crap. The G4 is a low light shooter in stock auto.
And if you really need 2 separate G4s under the same conditions side by side to tell the difference then there is not much difference. It's the audio bitrate debate all over again.

heh, anything from 0.5s UP TO 30s isn't possible.
I would be very sceptical about replacing stock with cm camera until i see plenty of examples with cm.
Also bear in mind that vendors keep a very tight lock on their cameras and don't share much with 3rd parties. yeah you can use a 3rd party app in some circumstances but you can never replace the stock camera in all situations. This stock cmaera that can challenge the likes of smasung and is touted as a major selling point of the G4. Yeah, i say its pretty special.
Which is a requirement to any one considering the CM path.
What i'm reading here is if you want CM then you don't care too much about the camera to begin with. That would not surprise me as people that are good with roms don't tend to be very good with camera and vice versa. it's rare to find both those skill sets in people.

[Q] [Q/DISCUSSION] Camera Slo-Mo 240FPS

I got really exited about the new OP Three, there are just a few aspects I don't like, one of them being 120fps filming instead of 240fps. I'm a complete noob, but I'm trying to inderstand why it can't record 240fps videos. As far as I know, our processor (SD820) can manage 240fps (see S7/G5), and I guess our camera sensor can too (IMX298), but I couldn't find that information.
Anyway, previously I was interested in getting slow motion on a DSLR camera (Canon EOS 700D), but I found some reasons why it would't be possible: http://www.magiclantern.fm/forum/in...r0ic25ieqeee0&topic=11570.msg113776#msg113776
I know there are lots of differences between a smartphone and a DSLR camera, but what I found interesting was this:
3. The internal buses that move the raw data from the sensor to the image processors can't handle that much data (1920*1080*14bit*60fps = 1.7 Gigabits per second)
Click to expand...

OP3 can record [email protected] video, which would require 3840×2160×30fps=248832000 bits/s, while HD 240fps video would require 720×1280×240fps=221184000 bits/s (I'm not taking into account color depth since I assume it'd be the same in both cases).
Furthermore, some time ago, when camera2 api was first released, PkmX achieved 120fps and 4K on a nexus 5, which couldn't officially do that and had a far older sensor.
Since OP3 will be really developer-friendly and its sources are already available, do you think it'll be possible for developers to get 240fps, even on low res videos? Can you think of anything that could be a limitation?
Anyway, if I buy the phone eventually, I'll learn a bit about development and try to get it.
(Maybe I should mention that I found this digging into the sources, but I don't even know if it's related

you know the nexus 5x initially just had 120 fps and now it has a 240 fps mod, but thats due to the fact that google camera had just restricted it directly inthe apk itself, people just edited the google camera and BANG 240 fps on the nexus 5x.. oneplus3 could be a different story. i really wish it had it though, im like so close to buying this phone ! in the end i might just end up with the nexus 6p due to this feature

I bought the 3. So far it's not looking good. It looks like the camera2 API implementation is broken for photos and who knows what for video.
They released some source and made a big show about it, but there is still proprietary code they haven't released and may never--they never did with the One which still has no camera2.
Might want to hold out on the 3 for things to settle and by that time the new Sony should be out with a much better sensor.
