Doubt about the size of the pictures - LG Optimus 4X HD

Hello,
I had a Galaxy S2, but now i have the 4X HD. I have a question: My S2's pictures had about 2,5mb (size of the file), and my 4X HD's pictures has about 1,4mb. Why is that difference so big ? Dont they have the same 8Mpx camera?
I dont know if i am wrong, but S2 has a better camera ? Am I forgeting anything about the configuration ?
Thanks for the atention,
Arthur Garcia

Yes we all discussed this before. Size is not big as you noticed. we all knwo that our camera has some problems (focus , night pictures).
May be we`ll have a update on the camera wich might take better fotos.

Picture file size depends also on the kind of picture (light, colors, etc...), what ISO camera use, and maybe other settings.
If the settings are "automatic" they'll change deppending of the enviroment where the picture is made soo, also the size.
We have the compression too... maybe LG software have different compression than Shaisung.

Thank you all people, i understood. So i hope in the future, LG give us an good update xD
I cant root my phone, my firmware (Brazil 10C) has some bug, so i guess i cant mod for camera V5. Am I right ?

not exactly, most important for file size is JPG quality compression (0-100 where 100 is 100% of quality but higher file size)...i don't know what is in stock camera, but it have strong compression and that give you worst quality but smaller file size, i.e. you can download ICS Camera or lgCamera from Google Play and change this settings to higher quality/less compression...

Soo, if not exactly, how you explain the same picture size selected (8MP) and different picture file size? Resolution is the same...
The stock compression should be none.
Of course that we can not have the quality of a 100% .jpg (or any other format) in a lower percent ... That happends not only with pictures, also sound or video files...
Some formats can have better quality with smaller file size but, thats another story!

Of course, the difference will always be, because every picture is different. As you wrote, it also depends on the details of the file size, but it will be a small difference, but certainly not so that the first image is 1.5 MB and the next is 3 MB.

1080P Video Recording!!!!!!

Alright don't chew my arse if I am not right, but I think I just might be...
Gspot image attached of a 10sec. sample video using the below settings and attached media_profiles.xml
What I have done is edited the build.prop with a new property using Prop Editor:
Code:
ro.media.camcorder.1080p=mp4,h264,60,24000000,aac,128000,44100,2
So property is:
Code:
ro.media.camcorder.1080p
Value:
Code:
mp4,h264,60,24000000,aac,128000,44100,2
I also made changes to the Media_profiles.xml file and have attached that file in zip format.
To install:
Unzip the file
using root explorer go to /System/etc
Rename media_profiles.xml to media_profiles.xml.bak
copy the new media_profiles.xml file to /System/etc
Change permissions to rw-r--r--
Reboot
Open up the camcorder
Goto Settings 1080P Shows HD+ on the screen when recording..
enjoy 1080P video recording...
FYI.. In 720p mode the same 10sec video had a file size of 14MB
In 1080 mode same subject matter video 10 sec. with a file size of 21MB.
Another build.prop edit:
ro.camcorder.videoModes=true
Default is false
This enables Video mode, which includes Video message, Normal, Slow motion, and Fast motion.
Hope this helps!!
The BIG question is, why do you want 1080P recordings? The optics can not really even support 720P and 1080P will not make it look better, probably even worse and the file will be twice as big. Playback of 1080P I can understand.
Just my 0.02
Cheers
nice post, but is the 1080p recording still only 24fps?
Also, to solve the spacing problem in the post, put the lines inside the Code tags
Code:
ro.media.camcorder.1080p=mp4,h264,60,24000000,aac,128000,44100,2

Being able to extract any frame and have it 2mp is pretty cool to me. It the highest resolution, if you're playing it on a nice full HD screen, it will fill every pixel. It does look better in 1080p

I'm actually glad that it's 24fps. If you think, any professional movie on a dvd only plays 24fps. When it gets up to 30fps, it plays faster and looks more like a home video, so I like the 24fps look better.
Thanks for this will try it out tonight!
Sent from my MB860 using XDA Premium App
Not work on Stock rom! At least for me...
It looks better but our software is not optimized to record 1080p yet. So videos are slightly choppy.
Sent from my MB860 using XDA Premium App
Works great on CherryBlur!
Still a little choppy during recording, but the output file is definitely 1080p at 24fps.
Playback is very smooth.
Nice find on the xml file.
Doesn't work for me too!!!
p.s. atrix has far more optics than just 2.5 mpx (1080p)

A agurzhiy and yusmiza... Did you change the permissions of the media_profiles.xml to rw-r--r-- and reboot after copying the file over and making the changes in the build prop?
does the front camera work? noticed in you xml you put the high setting for the front cam at 720P
Seems to work for me. At least 720 and 1080 the file sizes were different anyway (for the same time frame) Nothing to really test it on here at work.
edit: When taking pictures the 720 and 1080 file sizes are different also...though both say 3.8 mp still
i just edited myself!
Please tell me the version of your FW and is it a stock camera?
p.s. i do not care 1080, i need SloMo, but my buildProp has on default ro.camcorder.videoModes=true
Default was true for me
running Ken's GB beta 4 and yes stock camera
i'll try to copy your file. I found slomo and fastmo
but both of them, while playing are just usual video. Nothing faster, nothing slower, despite the fact that camera on slomo each second counts as 3 seconds (so it shows after 3 seconds that 9 seconds were recorded)
y2... Thanks for catching that!! I didn't realize I didn't put the front camera setting back to norm.. My front Camera doesn't work due to a swimming pool incident with my Atrix, but it will usually come up with a black screen.. now I get a FC.. I will make the appropriate changes and update the file.. Let me know if the new file lets the front cam work on yours...

the optics don't matter, it's the sensor. the sensor is also not able to capture constant data at the full 5 MP (video); it can take pictures at that level but it can't handle video at that level. that's why whenever you record a video on you digital camera, it's at a much smaller resolution, or why when you do burst-mode on some cameras, the maximum size is smaller than the regular MP rating.

[Q] Corrupt photos if larger than 5 MB, using any camera app

Hi,
I'm unrooted, stock V10h.
After noticing that the stock camera photos are very compressed (8MP photos never go above 3MBs) with no option to change that, I installed Camera Zoom FX. All seemed good, but then on a sunny day after taking *lots* of photos, noticed I couldn't view some of them on the phone, although thumbnails were there. Came home, transferred to PC, opened and noticed that the ones the phone couldn't display were corrupted. All of them, had a gray bar at the bottom, some more, some less. Obviously the compressed jpg stream was broken after some point.
Thought it was Camera Zoom FX's problem, because this never happened with the native camera app. Uninstalled.
Still wanting better quality, installed Camera ICS. Great too. But same problem too (on some photos again).
Went on to install Camera MX. Same.
Finally narrowed it down to this:
if resulting photo is > 5MB (more precise: if > 5130 KB) then it's corrupted
(and that's why the native camera doesn't have this problem: there's no way to choose better JPG quality for it to make 5MB photos).
I thought: memory speed problem. But then again, the photos were saved in the phone internal memory. Internal memory is not supposed to have speed problems. Anyway, I tried saving to Class 6 and Class 10 SD card, and the results were the same.
Anyone know about this?
Also, please report if your >5MB pictures are fine (in case you shoot at that quality), and what app you use to take them.
Note: the problem seems to be there with jpg photos in general, irrespective of device. Here's a link of someone experiencing the same photo corruption on a normal camera (Casio EX-F1). The problem with my photos is exactly as in the photo he posts a bit later in the thread.
Ok noone seems to know anything about it.
Could someone at least please report if you can get photos equal to or above 5Mb in size, whatever camera app you are using and whether the photos are ok?
(to get that quality, you must select 8 megapixels and then the highest quality in some other setting. For example camera zoom fx and camera mx have a percentage slider (set it to 100), while camera ICS names the quality (select ultra). Also a steady shot and lots of light is needed for the pictures to go up to 5Mb even in these settings.)

Just tested with Camera ICS.... Same issue as you. Photo was 5,266,434.00 bytes.
Using V10h Euro Open.
i had the same issue on deodexed ICS i had a week after purchase, and after i installed this mod:
http://forum.xda-developers.com/showthread.php?t=1855818
i tought the mod broke my camera, but i guess it was this bug/limit.
Thank you both for reporting. At least now we know it's an (LG implementation?) android bug.
Really annoying to me, as I would like to use the camera's full potential. Hope this gets fixed in the upcoming JB for 4X.
(although in order for something to be fixed, LG would have to know. And this problem surely hasn't received attention since it seems I am the first one to bring it up).
It would be interesting to see what would happen if someone with v20a tested this.
Yes indeed.
On another note, I also checked GeoCam and sometimes it gives an error (not enough memory or something). The photos that it saves with no problem are maximum < 5 Mb, so I assume it is the same problem. But this app demonstrates that there is a way for the programmer to know that during saving the photo something did not go as expected.
Where exactly the bug lies, is another matter.

i might try the mod in official 4.1 when it's out and someone releases a deodexed version, just to check if it works on JB.
this is quite a strange problem we have on our hands, i did some search on google, and haven't found many similar problems.

I too am anxiously waiting for the official 4.1 and was hoping that it would not have this problem.. just wishful thinking..
i already know it a long time ago, and i asked about this at the camera MOD thread by ksekhar http://forum.xda-developers.com/showthread.php?t=1855818. but no one seems to bother

Hello ksekhar. I found a problem in the LG firmware, it appears in your mod too.
In third-party programs (ICS camera+) and in your camera mod of the compression quality jpeg minimum, maximum file size.
In some conditions, such as the leaves in the sun, the size of the file begins to exceed 5 megabytes. Then the problems start.
This file is written to the error (broken jpeg file). I've been thinking why this is so and finally got it.
In your version, you just increase the compression quality to any situation the file size is not more than 4-5 MB.
Also, if you is not difficult, please do me a version (as we did earlier) which fixes only compression jpeg,
but the quality of compression should be a cross between the standard version and your version.
Or tell me how I myself can change the quality of compression.
For example (like photoshop - compression level from 0 to 12)
Original LG camera - compression 9
Your mod - compression 12
The required - compression 10.

i have this problem too
when photo taken exceeds 5MB.. it is broken...and it happened too often. any solutions?
Click to expand...
Click to collapse
Ok, that's bad...
For now, I check whether the thumbnail of the just taken photo appears correctly (inside the photo application). If not, it's a sign the photo has exceeded 5 mb. Then I go to settings, reduce the quality, reshoot.
Or, one can use Camera MX and set the quality slider to 90-95. Then the photos are better than stock camera, and they don't exceed 5 mb.
Since noone cares for this problem I can only hope the new firmware automagically hasn't got this problem. If it does.. we'll see then...
Bad news... Just updated to official V20a, and the same issue persists. a 5.02mb JPEG resulted in an image which was half ok, half greyed out and corrupt.
Only hope now a mod, or a custom ROM..
Ok, is there a way mother LG can be notified about this? (and don't tell me phone support in my country, they can only handle basic stuff. They won't understand what I'm talking about and respond like "use the official camera application"...)

Not that I know of.
i have no idea why, but yesterday i took some pictures with my 4x (with the stock lg camera app!).
the most pictures had around 1,5-2,5mb , one hat 4,7mb and one 5,05..
the ->5mb pic is corrupt..
never saw this error on stock, im using stock camera app on my CM
Anyway, i reported this bug to CM on the 4X forum, lets see if they can help. would good if more people confirmed this bug on CM forum..
I have a little experience about this bug.
Last time I flashed google's camera 4.2 with photosphere, camera.tegra.so and libnvmm_camera.so (modded to disable denoise filter) and stock camera. The result was that wherever camera I used (stock, cm, google's) the pic were corrupted (taking photos in dark). Just few of them were OK.
Here are modded .so files - works with CM10.1 (made by me, if you want i can made thread for them):
http://db.tt/2Lfxuehq - camera.tegra.so pasted to /system/lib/hw
http://db.tt/LXdwvJUZ - libnvmm_camera.so pasted to /system/lib
Sth more I will say when I come from holidays.

[Q] Camera fucntionality

Hi! I haven't bought my device yet, and I still have some questions.
the thing about the auto-mode, is it that it just takes 8Mpix photos? Also, I read somewhere that the device can take several photos, and you get to pick the best. Is this just in auto-mode, or can you still use that if you switch to use the full sensor-size?

You can use 21 megapixels in manual mode, but they're compressed to 8 megapixels in size but you are sampling from a better higher source

Oh, they're squished together.
Do you know if this is the work of the camera software or if the hardware somehow produces that sampling? If it's the first I imagine one could make a mod so that it actually saves the 20mpix high-res source.

camera settings help

I am able to see how to change the video recording quality under camera settings but I can't find how to adjust the mp for image size on the camera. sometimes I like to use a low MP so the files are not to large to send via e-mail. any help would be appreciated.
Thanks
The only solution I found is to synchronize with google photos and send the uploaded photo (google lowers resolution and size)

this is driving me nuts as well , is there no way to get it back where you can see the actual resolution settings and the aspect ratio ?
i dont know what to choose by these little images
So which setting do I choose if I want to take a low resolution image to send via e-mail?
Interesting your finding.....
The only way to adjust the MB would be by opening the camera.. but instead of selecting settings, select the [3:4], where you can select another type of picture size that this will change also the resolution or MB of each pictures.
Yes, I know it's not the ideal but trying to assist you

Why does S10+ have such bad jpeg compression ?

I took a ton of pictures, and compared many with S7. S10 is always super clean and smooth, without any noise, every picture size ranges from 1.3mb to 5mb tops. While S7 retains some noise in the blue skys, and can be edited after, the S10 one has macro-blocking from the start, and when I try to edit them a little, all sorts of artifacts start to pop up, like banding, it looks like 256 colored gif sometimes. I feel like when S10 processes and saves jpegs, it applys something like noise reduction 70/100, jpeg quality 60/100, if compared to Lightroom settings.
Samsung compress jpegs too much, the average jpeg out of the phone is about 2-3 mb, while jpeg converted from raw using Lightroom mobile is 6mb!
There is a new custom rom with modded camera app to get 100% jpeg
I noticed that too. Is it possible to change compression ratio on stock rom?
Nop
Unless you install a third party camera app with jpeg compression control.
If you want to use stock camera then take your photos in raw, you can edit them calmly in any raw editor
Thanks for the answer! Can You, please, recommend any third party camera app? Good RAW editor for Android would be helpful information too.

Good RAW editor for Android : Snapseed.
You also got Adobe Lightroom, but it is not for free.
