[Q] Basic definitions - Micromax A116

How is 8mp camera changed to 12 or 13 mp by roms, since no hardware is changed how will we get that much?
What is imei no? why is it so important?
What is interploation (someone told me this was the process to increase picture resolution but didn't understand)

Believe me!! imei no. Is REALLY VERY IMPORTANT!!!
And for the other 2 questions..haven't got any clue either!
Hit THANKS instead of posting it if I was helpfull in any way. __**XDA Rule**__

1. Imei no is like an unique id of your phone used by the sim cards.If it is not there your phone will not catch any network and after some time your sim may be blocked for being used without imei.
2. the 12 or 13 mp camera is not ahardware increase.the resolution of the photo is just increased incrasing its dimensions and some detail.
(a pic may be considered to be made of very very small squares.the smaller the squares the crispier the pic looks.increasing to 13 mp decreases there size and increases their no improving the picture quality)
(like a diagonal line is not a slanting line.if zoomed into it will look like stairs(bumpy).the smaller the stair size the smoother the slant looks from far away)

Interpolation here is altering the image size with changing the pixels and filling the gaps with the help of some algorithms.. because the sensor is only lower than the interpolate one.
You may have done the same with Photoshop

[Q] 3D Picture Resolution Improvement?

is there anyway to make it so that it stitches two 5mp pictures instead of two 2 megapixel pictures?
maybe in a rom?
just so that we can take 3d photos, but also have the 2d form where its actually nice to look at instead of a 2mp 2d picture.
just a thought.
Its two five mp cameras, not two 2 mps. Just checked it out in engadget and wirefly

yes i know, but when you take 3d pictures, its two 2mp pictures that are stitched together. you can notice it when you view a 3d picture in 2d.
Yeah
It really should be an option

yes, there might be a way. assuming this is a software limitation and not a hardware limitation.
to determine if its possible in the software, have to decompile and sort thru the closed source htc camera apk file. that is probably the only/best way to figure out the logic and coding htc uses.
is it possible? wouldn't know until we see the code.
see to be quite a few requests surrounding the camera on this device. perhaps it would be worth tweeting or mentioning on htc's facebook page as these types of requests seem popular. maybe they could release these added options in an OTA. would be even better if they just release the source code and we could compile/modify ourselves. in the mean time, next best option, decompile/modify the existing htc camera .apk!
hope that helps!
i am really interested in this too, could any of you smart people try to decompile ? i would done it myself if i only known anything about android but i don't.
so i hope someone could look into it !

I've been looking into the camera in the past few days. Take a look at my camera compression thread. I have a hypothesis as to why the resolution in 1920x1080 for each of the two images in 3D mode. Follow me here. In 2D mode @5MP (widescreen) the resolution is 2560 x 1440. This means that the 3D pictures are reduced by exactly 25% in each dimension. My hypothesis is that they use this extra 25% to post process (focus) the 3D image. If you think about it, the further away the focal point, the more the two images overlap. Likewise, the closer the focal point, the less the images overlap. They need to reserve this 25% in all cases because of the auto focus. It's kind of like how you go cross-eyed when focusing on something right in front of your nose.
EDIT: See my attachment for a visual representation of the wasted area
EDIT: Also see my chopped pictures. I took two pictures. The first in 2D and the second in 3D (converted back to 2D). I had the camera in the exact same spot for both pictures. You can see that the left part of the picture is chopped off in the 3Dto2D picture, but the detail is the same. It's like the image is just cropped.

[Q] Working camera quality fix for sk17i

Is there a working camera fix (mod) that will allow for changing compression settings in the camera as well as reduce the image processing which results in detail loss :?
I just bought the device and would love to be able to take better images - and I feel that this loss of details can be avoided. images at 5mpx should not be 500kb in any case and the details even on older devices with lower mpx show more details.
Maybe if there is a working fix people can also post sample shots to see how it really works. (ICS or GB)
Plus this mod could also be implemented in other roms later on so that more people can benefit.
Thanks

Just read through the entire thread + all the linked threads to that ...
as it seems compression is not the problem here ...
the camera drivers need to be altered or drivers from a better image producing device to be ported....
anyone has a progress on that :?

I don't know much but I think the drivers are proprietary and cannot be edited.
I guess we should wait for Sony to release the ICS update, maybe the camera will get better
Hope something could be adapted from another device even - better adapted to make good photos. Fingers crossed
Anyone tried updating to ICS? The camera quality has been improved. Now the image size is ~2mb i guess
Forget about driver replacing: if i understand correctly you mixed old methods for phones (for example K790i on platform db2020 etc.): changing acoustic, display, camera drivers. I just tryed all of this by myself in the past ^_^ In android smartphones there is only way to improve quality - change camera's APK file Because drivers for internal absolutelly incompatible between different devices. You can find everything you need on Apps section of our subforum

It may be possible to improve the photo quality output of the SK17, but I don't think it's going to do as well as some previous generation camera phones just due to the physics of it all.
If you take a look at the lens used on the SK17 vs. iPhone or even the X10 Mini Pro, you'll find the lens is smaller, as well as the aperture ect... This means a smaller image sensor which ultimately means lower PQ.
The only way it could match larger lenses would be if they had used more advanced image sensor technology such as EXMOR to improve sensor sensitivity or speed, as they did in the Xperia Ray. Unfortunately they didn't use this technology in the SK17 series of phones.
I'm hoping up coming newer versions of the phone will make use of both a larger lens as well as advanced sensor technology.
If you use a camera app. such as 360 camera, you can defeat the compression, but the pictures don't really look much better to me. The negligible improvement in PQ may be the reason why Sony implemented this level of compression in the first place, since the lens isn't able to deliver.

I partially agree with the sensor being small - hence output suffering quality - however I've had a nokia e50 long time ago with an even smaller lens at 1.3mpx which produced similar images (well sometimes) in terms of quality. I would be interested to see how the device performs without the crazy compression settings ... I have my feelings that output will improve vastly.
Btw on GB with camera ICS+ the images were very good actually - even though I wish they were not as compressed as they are - nothing else.

[Q] MT6573 poor video performance

I have other non China android phones that records video pretty impressively under bad or average lighting conditions. According to MT6573's specification, it has support for advanced 3D graphics; multi-format video capture and playback up to FWVGA 30fps; high-resolution camera support to 8MP.
An irritating thing is that the camera is TOTALLY USELESS under average or poor lighting conditions when recording. I have tried with different apps and they all gave me disappointing video recordings (almost total darkness clips).
Just wondering if I'm the only one facing this problem. Is there anyway to rectify the problem?

In such un branded devices its common...
Its like in Nokia or Samsung phone 1.3 mega pixel camera gives the same result as 5mp of that micromax or karbon...
So in such cheap phones its not necessary that if they write 8mp than it will like 8mp of that Samsung innov8...
we all should be polite enough to press thanks for anyone who helped US.
Yeah, thanks but is there a way to 'reduce' the pixel count? I don't need large recordings, just bright ones
You can change resolution of video in setting
Higher the resolution better the clarity

Did that but it didn't improve the brightness level when recording. Is that a problem with 6573 platform in the first place? In that case, is the 6575 and 6577 also the same?

Camera question

I bought my One x+ after trading in my old Desire HD. So far I'm finding that I liked the picture quality on the DHD more than on the OX+-- the colors were a bit more vivid and the pictures on the OX+ seem a bit oversaturated. My question is-- what determines the picture quality? Is it more the hardware or the software? The cameras on both phones is 8MP-- does the picture quality stem from differences in softare? If so, would it be possible to get the old camera sofware from the DHD? Or is it a ROM thing? Or is there more to it than that?

The One series is the first to use HTC`s imagesense. As such the images are quite compressed, assuming you are rooted, try flashing lypota`s mod camera or just use the attached media file. Both of these will set image quality to 100 (no compression) and increase video bitrate/mbps.
http://forum.xda-developers.com/showpost.php?p=35746341&postcount=175
lypota's awesome camera mod is a must.
Always comes down to the software and libraries, plus there's always a balance with sharpness/exposure which you should fiddle with as auto settings are garbage.
Eg at the SG4 and the Xperia Z, same 13mp Sony camera bsi module but very different results on auto settings.
I'm running Elegancia which I believe has Lypota's camera mod built into it, as for the other one, sounds tempting, but I take a lot of pics and I'm afraid if they were 3-9 megs a shot I'd fill up my memory card in no time haha. Might give it a whirl though. Still, on my DHD the pics were between .75 and 1.5 mb's on average and I just had to point and shoot with no tweaking of settings...oh well. Thanks for the suggestions.
Does anyone have any experience with Camera ZOOM FX? Would it be an improvement over what I have? (HTC Camera with Elegancia mods) Or would it be a supplement? Sorry for the noobness.

Camera quality terrible

Hello all,
I just bought a Z2 (second hand) as I wanted a phone with a high quality camera and apparently the Z2 was one of the best out there at the time of its release.
Unfortunately thus far the photos I've got from the Z2 seems pretty low quality with lots of noise and lack of detail. I've tried using manual mode and setting the ISO to 50 or 100 but the quality is still bad. Not really any different to my old cheap o Vodafone own branded phone. And the front facing camera is absolutely dreadful!
I've looked around for a solution but not found anything conclusive.
Does anyone have any advice on a way to improve the picture quality? Any particular ROMs or apps I should use. In currently on stock 6.0.1. I've read that some peoplefound that picture quality had degraded with each OS update from KK.
Many thanks

It's actually false, it has been the same way from KK,LP & MM
I tried flashing the Cyberian Mod and I've seen some slight improvements
I also bought a second hand z2. the camera was awful at first just as you described but then I saw a thread somewhere here on xda that suggests scratching off the thin coating on the lens of the z2. I scratched mine with a card and now it works great.

I don't understand the Z2 has such good reviews of the camera. I have seen some pretty good photos that other people have taken on z2s though.
I've heard that unlocking the bootloader can effect the camera, though I'm not clear whether in a good or bad way.

Ofcourse in a bad way, because sony removes the BIONZ processing and some other features if you unlock your bootloader

Some sample images...
I have just transferred some of my photos from the xperia z2 on to my PC to have a closer look, and I'm even more shocked by the awful quality. It looks like a budget phone from 2012!
I took a few sample shots using the 'Superior' Auto mode, then using the Open Camera App, then one on my old cheap-o Vodafone Smart Prime 6 so that I could compare.
Look at the attachments, they are in the order mentioned above, all at 8MP.
1. Superior Auto produces a dreadful contrasty, high-noise, low-detail image.
2. Open Camera does a better job, slightly more detail. I was unable to set the ISO in the app for some reason.
3. Old Vodafone Smart Prime 6 has perhaps slightly less sharp image, but overall is much less contrasty and produces a much nicer image, with natural looking detail.
WTF?! how is this top of the range Xperia producing images worse than a low end phone?!
Any help greatly appreciated.

Strange , i often do photos with my z2, and i have a more natural image than others. Ok in auto sometimes they are more overexposed(but very less with marshmallow). But use manual, -0.3 or -0.7 ev,esposure misuraction multiple and touch autofocus. Better than auto mode. If you mod your z2, use cyberian mod and the quality improve a lot. The version with worse camera is kitkat...orrible quality with auto mode. Then with lollipop and marshmallow,improve a lot the camera.

You must install flashtool and use some guides to flash 575 kernel. Then the guide is simple. I use often this guide ,but when i'm on recovery to flash 291 kernel and supesu, i don't flash them but a new rom. It's the best way

Soooo.... rooted and installed Cyberian... camera is still god awful!
Is there a known issue with the z2? It seems that half of owners think the camera is brilliant and half think it's rubbish. I've seen evidence that would point towards there being a quality control issue at Sony, with a large quantity of faulty handsets being sold? (See this post, amongst others)
My back camera is definitely sub-par, performing worse than a low-end phone, and as for the front camera.... well, it looks like a blown up 0.2mp image.
Some more examples attached. They alternate rear camera, front camera.
I'm surprised Sony hasn't faced a large lawsuit around this issue.

First: use 4:3 resolution instead 16:9. 4:3 is the resolution of sensor. 16:9 pictures are worse. There is a 12 mp resolution in cyberian Who improve a lot pictures. Why did you don't try it? if this persist, control that sensor have the lens antireflex corrupted. This is second hand z2. So this is possible

Checked closely both back and front lenses for damage but they both look fine. The phone in general is in a 'like new' condition.
