[Q] Camera speed - Galaxy S II Q&A, Help & Troubleshooting

Hey, is there way to decrease camera delay before taking next picture?
It would be handy for HDR applications where your steady position is very important.
SGS III has burst mode so it shots 3 pics per seconds. I'd like to have it on SGS II, so far it shots 1 picture per second, but I tested shutter speed it is about 200 ms delay only so...

...

You can try fast burst camera lite https://play.google.com/store/apps/details?id=com.spritefish.fastburstcameralite, capable of taking 30 shots per second. And yes, the no. of shots will be still limited by your hardware.
Or Ultra Burst Camera https://play.google.com/store/apps/details?id=com.spritefish.ultraburstcamera (from the same developer though), can take up to 40 shots per second, but in black and white colors only.

yeah I am aware of such apps but they do small pictures so rather are not useable at all, because I could just cut frames from the full HD video
I am curious about because sensor of SGS II is capable to record full 8 Mpix movies 10 frames per second... so what stops this from taking 3 pictures in 8 Mpix, if is capable doing so 10.
Isn't there any driver trick to achieve such feature?
BTW: any of you tried SGS III with HDR Camera+ or ProHDR Camera? I am curious about speed

the reason why it cannot process faster is due to pink spots taking longer to process lol,was reading your other thread
i want to know this too, on GB the camera delay was shorter than the ics roms ive tried, i even got a class 10 card for it, wait for JB and see if they improved
write to ram then storage?

[Q] Slow motion video recording?

I would really love being able to do some slow-mo videos with my SGS2, any way to do so?
The camera simply isn't built for that kind of use. You could do it, if there were software, but the framerate would be atrocious.
Here's an app for playing back videos in slow motion...

Probably the best and only solution. The camera was only built for up to 30fps I believe. If you know how slow motion cameras work (very high frame rate), you should see how this is a problem .
I'm bringing this thread back to life to save cluttering the board up with yet another similar one. I've been looking for an app to do the same thing and have, like other searching, not found anything to suit.
The reason I'm still chasing it down is that I had the Samsung Jet before my SGSII and even given it's age and utter lack of power compared it had the feature to be able to record video at high speed so that when played back it would be very good quality slow motion (25% speed if my memory recalls correctly).
Now, if that phone could do it so long ago with little native power and a poor camera then surely the SGSII could do something like that at the very least, even if the max video size had to be dropped to 640x480 or similar to keep the framerate more locked in?
Want that too!
Can somebody pls answer this question.. Is 30fps hardware limitation?? Really??
I once had Samsung OmniaHD with 8Mpix camera, probably not much different from any other, and 320x240 resolution it was able to capture 120fps..
How can it be a limitation of hardware? Isn't it possible to write an app that would capture even 240fps at lower resolutions?

I'm searching for this since a year from now, I think the problem remains in the drivers and not in android SO, there is one or two android phones that support is, but I dont know how exactly, if I dont misstake samsung galaxy note 2 and one motorola has slowmotion, I belive that they build a driver to use de camera as fast as possible, on other devices I think that is not possible unless some can build such driver, and that probably will need to do in some native assembler code of each device cpu and irqs, unless the company release that driver
the functions of android to get frames from camera are very limited to useless stuff and pre-set formats and fps
I dont know whats about with android 3.1+ or 4, maybe thats SO has this functionality natively
get fast fps from a ccd camera is not a MP issue nor too much CPU requeriments nor related to amount of RAM
with a windows mobile 6.1 device such samsung omnia i900, that has a 625mhz CPU and a 5MP camera you can record 120fps in 320x240, the camera of this phone has ISO 800 (it doesn't mean 800fps, but means that it can get a very tiny little power signal from sensor in a very short amount of time) but android cameras discard this features and incorporates functions very limited and related to normal users

I don't think you understand the concept of cameras well. The hardware determines whether it is 30 or 60fps and not the software.
For slow motion, the highest a consumer (or affordable) camera does is 1080p at 60fps.
There are cameras like phantom hd that do well over 1k fps but they cost 100k

Not completely accurate.
For a consumer camera, the highest framerate at 1080p might be 60fps like you say, but some low cost consumer sensors can do high fps at lower rez. My $100 Canon Elph 100HS from 2011 will do 640x480 at 120fps or (I think) 320x240 at 240fps. I've used the 480p120 option and it came out very nice for sports use, especially for reviewing batting swings with players. The sensor tech for fairly high frame rate at decent (480p) rez is not limited to >$1000 cameras, leading me to believe it's probably more software related. I don't know enough about the sensor in the GSII though.
*Edit*
Apparently the Galaxy S II uses one of two identically spec'd (according to Anandtech) sensors from either Samsung or Sony. The Sony IMX105 specs are here. According to that page the sensor should be capable of 120fps at 1/8 sub sampling. I am not entirely sure what they mean by 1/8 sub sampling, but I would assume that it means using 1/8 of the effective pixel count or about 1M pixels. If all that is true, then the hardware should be capable of 640x480 at 120fps. Some assumptions there, though.

[Q] Video recording in and out of focus

I am stock unrooted(till my 30 days are up) anyway I have seen a bunch of concerts recently and recorded video using my HTC Inspire, then with my brief time with the LG Thrill, and now with the Galaxy S 2 and while the galaxy s 2 seems to give the best quality recordings it seems while recording it will blur the video for a few seconds like its trying to focus then it will go back to normal it may do this once or twice during a 2-3 minute video yet I never had this problem with my Inspire or LG Thrill just wondering if I am missing some settings or what the deal is?

Most likely the other phones do not have the feature of
continuous auto focus during video recordings.
Perhaps one of the devs will include a mod in these custom roms
which can enable or disable the auto focus feature while recording
video clips.
(not many camera phones have auto focus during video recordings)
I guess I don't understand the continuous auto focus, to me that would mean it would auto focus always so I wouldnt get the blur issue. I went through the video recording settings didn't really see anything I could do that would remedy the situation.

Continuous auto-focus in i777 SGS2 means that it will
auto-focus as needed automatically while recording video.
So when the foreground or background changes and people
or objects are closer or further from the lens that's when
it will automatically try to auto-focus for optimal results.
I don't see too much of a problem on my test video but then it's not moving "too fast" like people/motion.. only cars passing by.

This happened to me while at the gun range, kind of anyways. The camera was blurry for the first half of the video like it wasn't even trying to focus, then when it did I guess it didn't go out of focus again. Very odd. Now that I'm on MIUI this doesn't happen, this video is from when it was stock unrooted.
http://www.youtube.com/watch?v=rcBAAOPvhv8
To be honest, on the stock/unrooted version I was running, I was having the exact same difficulties. You would expect that the camera wouldn't have to test its entire focus length before finding one that works and goes back to it.
It's not as noticeable when recording objects far away whose distance isn't changing, but when something passes in front of the camera or you move it to something slightly closer and it loses focus at all, it takes a good 1-2 seconds to refocus. That's a lot of time.
I was just thinking, could this be caused by my video recordings running off a 16gb class 4 kingston sd card? If so would I need to up the class or could I just switch my video recordings to go onto the 16gb of internal storage space? I may just switch it to internal and try a video and see if that is part of the problem.

Is it possible to increase fps in sgs2 video camera at lower resolution?

Hey guys, i take my phone on trips to take snapshots and videos are 2 of the list of reasons, the quality is pretty great when taking videos too but what bugs me is the 30fps limit, it doesnt semm to be 30 at all, its more like 24 or less because everytime i change the angle even slowly the image gets all shaky and blurry (nothing to do with the autofocus) that makes me think its something to do with the low fps limit but in case im not anyone knows how to avoid it?
Also when im taking lower resolution videos like 720p the fps is still 30, is there no way to change it to 60fps at lower resolution?
Thanks in advance!
At the moment its not possible to increase the framerate over 30fps.
I have a Samsung Wave capable of record at [email protected],I miss this capability in the Samsung Galaxy S2, I think it could do it at higher resolution.
If you cant record in stable 30fps in the Galaxy S2 look at this thread:

Meh, many problems with this phone regarding camera, its such a shame it has so much freaking potential... and yet they decided to let it rot with its issues.
I guess ive learned my lesson with samsung, probably will go for Sony next time but i hate the fact that i wont get OLED screen.
Thank you for your reply and for showing me that thread

slow motion camera

Has the SIII a slow motion camera like the htc one x?
It has alot of functions, but don't think so. Would be cool though!
In the camera filming mode the only options you get are: edit shortcuts, self recording, flash, recording mode (normal or MMS size), exposure value, timer, effects (negative, b&w, sepia), resolution, white balance, outdoor visibility, anti shake, guidelines and video quality.
Hope it helped!
sure helped!no slow motion for galaxy sIII
there's some apps but they are not working..
The thing is that the camera itself records just 30 frames per second, that's just over the comfortable zone of smoothness (you need around 60 for a good slow-mo). I don't see how apps could help with this one since the speed of the sensor matters here.
galaxy s3 camera lens has the capability of doing slow motion videos @ lower resolution, wait for the mods.

Just download the Note 2 Camera mod here by HyperX and flash it: http://forum.xda-developers.com/showthread.php?t=1691145
It comes with 1/8 speed slow motion (12.5% speed ~ 1 second recorded is 8 seconds video) and it's working for me. Make sure to read the thread first to make sure you got the right software first.
Good luck buddy!
IT--
Note 2 has slow motion!
Maybe someone will be good enough to liberate the slow motion from the Note 2 to other platforms ))

Good Thread, also interested.
S5 camera doesn't do 240 FPS, it has the same 1/8 slow motion, but it shoots at 120 FPS, and the video output is actually 8 times slower with 15 FPS. with 240 FPS i would be 8 times slower but with 30 FPS for a much smoother motion.
Thanks!

I don't understand? 1/1 would be 30fps 1/2 would be 60fps. 1/4 would be 120fps. Last but not least is 1/8 at 240fps. So yes we can record in 240fps.
Click to expand...
Click to collapse
1/8 actually means that the video would be 8 times slower than in reality, for example if you film 1 second, when you play it, it would have 8 seconds. and the playback video is at 15 frames per second, 15 x 8 seconds equals with 120 frames shot. the video was 1 second so, 120 frames per second you can record the same 1/8 speed, but after that the video you watch has 15 FPS, it it were 240 FPS the video would had 30 fps.
deadlocked007 said:
Lol I still don't understand what you are saying. The human eye captures 30 fps so reality to us would be 30 fps is it not?
Click to expand...
Click to collapse
Uhm... The human eye captures an infinite amount of "frames", its how our brain processes the images perceived by our eyes that changes things up and we can actually see up to about 250-300fps. Which is why looking at a 60hz and a 144hz screen is a completely different experience.
deadlocked007 said:
So then what is the fps for "reality" like you were saying?
Click to expand...
Click to collapse
"Reality" would be recording and playing back at the same fps... If you record in 240fps and play back in 240fps, it's going to be normal speed... However, if you record in 240fps and play in 30fps, it will play back in slow motion. There are plenty of apps that will slow down any video taken, however, those apps can not create more data than was recorded by the camera.
Recording at 30fps and playing back at 15fps will be the same slow motion "speed" as recording at 120fps and playing back at 60fps... etc, etc, etc... If you record at 24,000fps and play back at 12,000fps, you are going to see the same "speed" as the 30fps video played at 15fps. The difference is the quality. When you have more fps, you can slow it down further before it begins to look choppy.
The higher the fps, the more you can slow the video before it gets choppy.
The S5 will only record 120fps, record a slo-mo video at 1/4 speed and then record one at 1/8 speed and look at the quality difference. The 1/8 speed video looks a lot less smooth because it is the same fps at the 1/4 speed video, but they have slowed the playback speed on it.
