camera mod to improve picture pixilation?

Can someone attempt to make a mod that will make pictures less "grainy"?

Is this even possible?

I'm not sureMaybe I'll find a way. Fyi please take this question and post it in the question answer thread. Not in devolopment

isn't grain determined by ISO, PPI, or focus?
obviously, you can't increase pixel count since thats on the sensor....
ISO...you'd need less of it if you simply introduce more light....
focus hunting...might be fixable via software...
what could be fixed by the community?

No questions or requests in the dev section, please.

First, sorry for posting this in the wrong section. This should be possible some how? I know you won't get fantastic pictures with 5 mp but they ought to look better than what this phone pumps out.

I believe the ISO sensitivity is the main problem. It's how they're able to get the near-instant captures, but it has the downside of introducing high levels of noise into the image. There's nothing in the public API that allows you to control the ISO sensitivity, so you couldn't simply write another camera app with those controls (unless there are private methods for this that could be accessed via reflection...I need to download the source code sometime).

it is possible to have such mod
i had my Nexus One and someone modified the media_profile.xml and significantly improved the jpeg compression (unrelated to ISO or noise or anything)
I am also hoping for some expert to do similar things on Galaxy Nexus
at this moment my Nexus One takes better photos than my Galaxy Nexus
http://forum.xda-developers.com/showthread.php?t=1011810 <-- this is for Nexus One
I did some research and took a guess
the original media_profile.xml in galaxy nexus is:
<ImageEncoding quality="95" />
<ImageEncoding quality="80" />
<ImageEncoding quality="70" />
<ImageDecoding memCap="20000000" />
I think, similar to the mod in nexus one, we can change it to
<ImageEncoding quality="99"/>
<ImageEncoding quality="90"/>
<ImageEncoding quality="80"/>
<ImageDecoding memCap="25000000"/>
to have similar effect

Hi,
I know this mod works for example for my other phone running CM7 (HTC Sensation) by setting values media_profile.xml to 100 for all the line "ImageEncoding quality=**".
I think there were no more compression, a photo going around 2.5 / 2.8 Mo to about 5.2 Mo with this tweaks,and quality is here (ok for a 8MP camera).
I tested on the Galaxy Nexus,edititing the media_profile.xml to set the values to 100 for imageEncoding ... No improvement...
I think something else must be edited in camera.apk (by decompile),but i'haven't the knoledge.

[MOD] Video Bitrate Control (20-50mbps vs 10mbps stock) **NOW with demo link***

I was tinkering with media_profiles.xml yesterday and it appears that modifying the bitrate settings in here affects the camera. The stock bitrate min/max values are:
min: 64000
max: 12000000
Videos shot with these settings are usually 6-10mbps bitrate. I have changed these values to:
min: 35000000
max: 60000000
And my videos are now between 20mbps and 50mbps (huge leap!). The file sizes are bigger but I'm assuming this has to mean the videos will be somewhat better quality (my guess is mostly in low light when the ISO is cranked higher). I don't understand very well how these values are all used in here, but adjusting the bitrate ones does make a difference. Although framerate for 1080p says 30 here, they always come off camera at 24fps so I'm not sure if framerate (or any other changes) will work here.
Any value higher than 60000000 for the max will cause the camera app to crash, so I think this is a good max for now. This mod has been done on countless other devices, so I'm in no way discovering anything new, I just decided to poke around and see what changes work
Here's some more details for what to modify (to apply this mod to 720p and 1080p):
Starting at line 127:
Code:
<EncoderProfile quality="720p" fileFormat="mp4" duration="30">
<Video codec="h264"
[COLOR="Red"][b]bitRate="60000000"[/b][/COLOR]
width="1280"
height="720"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="1" />
</EncoderProfile>
<EncoderProfile quality="1080p" fileFormat="mp4" duration="30">
<Video codec="h264"
[COLOR="red"][b]bitRate="60000000"[/b][/COLOR]
width="1920"
height="1080"
frameRate="30" />
<Audio codec="aac"
bitRate="96000"
sampleRate="48000"
channels="1" />
</EncoderProfile>
And one other spot, line 340:
Code:
<VideoEncoderCap name="h264" enabled="true"
minBitRate="[COLOR="red"][b]35000000[/b][/COLOR]" maxBitRate="[COLOR="red"][b]60000000[/b][/COLOR]"
minFrameWidth="176" maxFrameWidth="1920"
minFrameHeight="144" maxFrameHeight="1080"
minFrameRate="15" maxFrameRate="30" />
Additional mod:
People have claimed on other devices changing this setting produces higher quality images from the camera, starting at line 216:
Code:
<ImageEncoding quality="[COLOR="red"][b]100[/b][/COLOR]" />
<ImageEncoding quality="80" />
<ImageEncoding quality="70" />
<ImageDecoding memCap="20000000" />
Steps to apply the mod:
1) have ADB setup and working (not explaining that here, plenty of other threads for this)
2) cd to some directory to work in (I just use the desktop), ensure ADB is in your path (google that part)
3)
Code:
adb pull /etc/media_profiles.xml .
to pull the media_profiles.xml file to whatever folder you're in with the terminal.
4) Make your modifications, save the file (maybe keep a backup of the original file if you want).
--- workaround because adb remount doesn't work] ---
5)
Code:
adb push media_profiles.xml /sdcard/download
6) Use root explorer to move the media_profiles.xml file from your downloads folder to the /etc folder (make sure to mount /etc as R/W before you try to move).
7) Reboot phone, all set!
EDIT
- or just use Root Explorer (available in the market) to do the changes, reboot the phone and you're done!

Any way this can be packaged up into a CWM flashable zip file to make it easier on those who are not familiar with using ADB?

You can also use soemthing like Root Explorer to make these changes directly on the phone.
Change the directory to R/W
Long press on the file and when the menu pops up, select Open with Text editor.
Make your changes
Save and exit.
Make sure the permissions are RW R R
Pull the battery and reboot.

[OT]now I'm wondering if I should be too[/OT]
Have you tried taking two videos that are as close to identical as possible, one with the stock settings and the other with the mod? That would show if it effects the quality at all.

Root Explorer Method
I just used the 'RE' method and it worked just fine [MAKE SURE TO TOGGLE RW, LONG-PRESS ON FILE, OPEN IN TEXT EDITOR, MAKE MOD's (BE CAREFUL TO MAKE SURE YOU'RE MOD'ing EXACTLY WHAT'S IN THE OP !!) THEN SAVE CHANGES & EXIT > AFTER THAT, HOPEFULLY WE PROFIT
... however, I cannot comment on the difference the modifications have made. If the OP is correct in his research, then I can't see why this MOD wouldn't be a PLUS !
BTW, Just to be SAFE, I moved a copy of my unmodified media_profiles.xml to my sdcard ... 'RE' will automatically create a .bak file when changes are made, but im extra cautious when modifying certain system files that I haven't dealt with before .... better safe than sorry, they say

Glad to see some replies!
I haven't done an exact side by side test yet, but typically higher bitrate will produce better quality gradients in videos (things like smoke, color changes in walls, etc) and should be especially noticeable in low light video where the ISO is very high.
I got the idea because I was a developer of Magic Lantern for a while this past year, and one of the great features it adds to canon dslr cameras is the ability to raise the bitrate (from 25mbps or so up to almost 80mbps), and makes a huge difference in quality.
Generally things with high complexity cause it to shoot at a higher bitrate as well (since it is a variable bitrate, it changes). Examples would be trees with lots of tree branches and stuff.
I'll try to get a comparison up later this week, I'm still waiting for my macbook pro to be shipped back from applecare.

I just shot a video walking around outside and it ended up being 45mbps. I can't upload though, youtube is having some issues.. will try again later today and post it here.

Thanks for the MOD. Since I like modding as well, I've put this into Axi0m2.3 and saved as a personal Clockwork image. Only thing that I notice is that since my sdcard file system is fat32, I can only capture about 5 minutes worth of video. I'll have to check out the difference as well and either format my sdcard ext4 or disable the mod.
Thanks again for the tweaks.

Awesome. I have edited the OP to include a youtube link to a demo video I just shot, make sure to check it for me (I can't play HD videos on this computer, I'm curious how it looks on youtube).
That is the only problem, the higher bitrate will cause all videos to be quite a bit larger. The video I just uploaded to youtube was 262mb.
Another note on fat32: a limit of the FAT filesystem is that it has a file size limit of 4gb, so that could be an issue we run into (people trying to record longer videos).
Also this mod could be problematic for phones other than the Galaxy Nexus which use an internal SD card. Read/Write speed for the card limits bitrate a lot. Luckily the g nexus has internal memory though which is very fast, so it shouldn't be an issue for us.

Video looks good to me. Just changed my media file to your setting. Will try out today when I go out. Need some comparison videos of the same scene with stock settings and then yours.

24fps is the stand rate. 30fps is just for marketing trick.

50mbps give huge file size...
can you please make a 25mbps MAX mod?

Where it says image encoding why not make them all 100 instead of leaving 80 and 70?

Not sure if serious. :/
24fps is just the film standard. 30fps is standard for a consumer videocamera, that and 60fps (which is far preferable, in my opinion). I seem to be one of the few people that feels this way, but I would prefer that films be shot at 60fps as well.

Echoing an earlier post, I'd love to see if anyone can change the JPEG compression on this beast... it's got to have more in it.

Camcorder hack for (Much?) better video recording

OK,I guess most experienced people would know about this,but still,here goes.
If you have a root browser(downloadable from play store),then you can edit the media_profiles.XML found in system/etc.
This can be edited to get your video recording from 640*480 @ 24fps to 720*480 @ 30 fps.(This is excellent for viewing on the wildfire S.)While technically higher resolutions and frame rates are possible,the stock Gingerbread camcorder app doesn't seem to list it in settings.Plus,higher frame rates don't work properly for me anyway.
So,here's how to do it :
In media_profiles.XML,under encoder profile high, change the width to 720,height to 480 and frame rate to 30.
(I'm not really sure about the following part,although no harm in trying.I'm just not sure whether this is really necessary).
Under each of the encoders below that (h264,h263,m4v) make the maximum height and width to anything you want above 720*480 and frame rate(if below 30) to 30.Max bitrates can be changed too,if you want.
I think its possible to change the camera encoding quality too,although for general day to day purposes,It's not too useful.
I'm open to any suggestions/Improvements if found.
Thanks for reading!

have u tried it??

Well,yeah.I don't see how I could have known this otherwise.

Actualy on the stock 2.26 these values are 720/480/24 by default dunno what rom were you testing this at.

If you do it once,even if you completely reset it,it goes to 720*480/24.
Maybe it's an update by HTC,as initially it's supposed to be 640*480/24.
Anyway the main thing is changing the framerate to 30 fps.....really improves overall video recording.

[MOD] Video Recording

Video/Audio Recording Mod​
OS Version: TW 4.2.2 (will be making a 4.3 version soon)
Notice: Higher bitrates increase file sizes. Please keep this in mind when recording. We should all know this by now so I won't say anything else about it.
Also I suggest recording to internal memory if you're external sdcard has low write speeds. eg. you're using one from 5 years ago.
1080p New (Stock)
Video:22 Mbps (17 Mbps)
Audio: 320 kbps (128 kbps)
1440x1080 (4:3)
Video:17 Mbps (13 Mbps)
Audio: 320 kbps (128 kbps)
720p
Video:15 Mbps (12 Mbps)
Audio: 320 kbps (128 kbps)
Audio Info:
Sampling Rate: 48 kHz on all which is stock.
Channels: 2
I'm probably going to drop the 1440x1080 profile and just take 720p to 17 Mbps since I don't think anyone uses that resolution much. Also, the FPS is still 30 but I'll try to increase it. There is the option for 6 channels using LPCM but I'm leaving it at 2. My first attempt using 6 channels came up with nothing useful and I'm not sure what the quality will be like anyway.
Questions:
Will this work with 4.3?
Yes it should. I'm not using a 4.3 Rom so let me know. I'll make one for 4.3 soon.
Will this work with an AOSP Rom?
No. You need TW framework to use it.
Can this be done for AOSP Roms?
Not really. The bitrates and such are more kernel/HW controlled in AOSP. Yes, a kernel could be made to adjust the properties of the gallery (camera) app but I don't mess with kernels - at all. Not my thing. That being said - it was done on the Nexus 4 and I'll post the link here when I find it if someone wants to try.
Any bugs or issues so far?
None that I've ran in to and I've been using/testing this for about a month now.
If you have any issues, requests, or other questions let me know. If you'd like to know how to do this, see my sig and click on the links. Just make sure to hit the "Thanks" button if you use my work.

Hey there, I'm having trouble with this mod. I have flashed the module from op, then bought the snap her camera app, loaded your settings and when I try to start a video in p2, the camera app just crashes. I've tried manually replacing the media profiles with the "corrected one" and it seems to not work either. What am I missing?? Thanks

Hi, I want to ask about camera fps setting.
If I want to change my stock camera to 25 fps intead 30 fps. Can this be done by changing the framerate inside media_profiles_vendor.xml file.
I have problem with 30 fps setting, for it sometimes flickering with 50 Hz indoor lamp.

the link seems to be down. Can someone please contribute the download file? Thanks a bunch.

The link was down. There is no file anymore. Someone who downloaded this module, can you upload it and share new link in this thread please?

I'm personally not sure if this still works on PIE but give it a go and let us know....
