8MP (4:3) vs 6MP (16:9) image quality problems? - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Contemplating getting this device and played around with it in a store today morning...
When testing the camera i noticed ALL widescreen images shot @ 6MP are getting somewhat blurry-er as you move from center towards top / bottom corners. Like not in focus at all i would say. Check samples in GSMArena review, they have the same issue....
8MP images do not have this issue, at least not (that) visible on the screen.
What's up with this, can anyone confirm?

100+ views, no shouts...
anyone with a S4 mini can check some photos?

Not a photo expert, but can't say I notice that in CM at least. Can you link to an example?

I have used my s4 mini some days ago for over 100 photos in 16:9 at 6 mpx, no blurry or similar :good:

Could anyone please post any photo from 9195 running CM10.1 with maximum image quality?
Just to compare to stock quality.

Tilt2 camera?....

Ok, this camera states its 3.2 megapixels. But the picture quality is worse than the one from my old phone which had only 2 megapixels. Do I need to change the settings or anything?
Megapixels have nothing to do with quality, only size. Make sure you have the largest resolution picked and that it is set to SuperFine. Still, the camera on the TP2 is only so-so.
Wow thats stupid. I don't like the camera at all.
Picture quality also depends on the camera lenses used. HTC doesn't really use great lenses.
Sony Ericsson (I had the SE C702 CyberShot phone before) uses very-high-quality camera lenses, and the pictures it produced were great!

Well, if you have a 8MP camera vs. a 3.2MP camera taking the same exact photo, and you were to print a 3x5" photo from each, the 8MP should still give you better quality than the 3.2MP. The 8MP camera is able to produce 8 mil. pixels whereas the 3.2MP camera can only produce 3.2 mil. pixels. If you were to print the 3x5" photo, the more pixels, the clearer the image.

Again, that's not a quality issue, per se. Anytime you increase the size of a photo without increasing the number of pixels used to display it, the pic will suffer because things like compression artifacts and aliasing will be more pronounced and visible. Not that these things aren't present in both the 3mp and the 8mp images, they will just be more noticeable in the 3mp image that is displayed at the same size as the 8mp image. That's the real value of more megapixels, the ability to increase print or display size without the ill effects. But that has little to do with quality.
I've been a pro photog for the past 18 years and shooting digitally for magazines since 1997. I started with a sub-1mp camera back then and the quality was fine, but the low pixel count limited our ability to use digital pics for more than just 1/4 page shots or smaller. By the time we got to 4mp cameras we were using them for full page spreads without issue. An 8mp camera can now yield a decent two-page spread. Still, the quality of pics hasn't been increased with more megapixels, only our ability to display them at larger print sizes.
It's easy to confuse megapixels with quality and manufacturers share much of the blame for convincing consumers that more mp=better quality with their sales shtick, but when you understand that quality is not necessarily tied to size, you realize that application is the main factor. For instance a 2mp camera can shoot very high quality 4X6 photos, but blowing those same pics up to 8X10 will reveal the weakness in megapixels, not quality. At the optimum size for a particular mp format, more mp does not yield higher quality, only higher storage and processing needs. It will give you more flexibility in cropping if your skills with the camera are lacking, and more format choices when printing, but not higher quality.
So how would I get the best quality out of my camera?
Have you installed the cab that gives you more camera settings? It gives you a SuperFine setting unavailable on the stock setup. Do a search for it. Also, make sure the lens is clean. Handling the phone often causes fingerprints and smudges on the lens that reduce photo quality.
Thank you so much, do you have a link or know the name of it?
The one I found is ExtraCameraModes.cab.
Here ya go.
Ok, it didn't change anything haha. But thanks anyways
I thought it comes with Super Fine by default. Anyway, I've always had to play around with the light settings the get the color I wanted. I set the ISO at 200. And lighting also takes a toll on the quality of the picture.
Anyway, the camera sucks. i wish they had a button to turn off auto focusing when i need to take quick shots lol
Cameras on cell phones are more of a convenience than a sophisticated capture device. While some actually take fairly good photos, I wouldn't expect too much from any of them. They certainly aren't designed to replace a good point-and-shoot.
OK, well thanks for the help everyone!

[Q] Z1C Camera on Stock vs AOSP?

Is there a big difference in performance of the camera say on liquidsmooth (or any other AOSP ROM) compared to the stock sony ROM? Are the pictures still 21 megapixels? I appreciate any help with regard to this. Thanks !
1567
Came from stock and using LiquidSmooth now, some main differences I can see is greater options for ISO control on Liquid, but less precision in exposure values. Stock gives you fractions whereas Liquid only gets +1 or -1. Overall, I like the AOSP camera better since +1 or -1 exp is really all I need. You can adjust ISO up to 3200 .
Edit: Pictures are still the full 21 MP, and you get options for 60 or 120 FPS video recording but it keeps saying it's unsupported, so I'm not sure if it's actually been added yet.
Thanks for the response. Are the quality of the pictures the same?
I haven't noticed any difference, and I like to zoom in a lot to view small details. I'm not very experienced in photography, but the pictures still look really good. You can also customize the aspect ratio of 21 MP shots to 16:9, and more but I haven't bothered with that yet.
Bionz still works on aosp roms?
I'm not really sure how to check something like that, otherwise I would. It takes the picture instantly, reminds me of taking photos on the iPhone. That's with 4:3 21MP with any ISO and any Exp value. I think that means it's on, since after a little research I found Bionz is just the image processor. 16:9 21 MP takes a while to process, because I think it pieces it together instead of taking the picture like it does in 4:3.

The resolution, screen density & camer pixel of Z5 premium is untrue

Hello ? everybody and expertise,
I have install CPU X app, on my z5 premium then i got shocked whe i found out that my resolution is 1080 x 1920 pixels and screen density is 403 ppi aside from 803 ppi more over i found the camera pixel is 8 megapixel aside from 23 mp
Any idea about whats happening with our handset
The phone runs in FHD. The resolution is correct. It only runs UHD in media content, photos and videos. Have you ever saw a review of this phone? This is well know by now.
So you bought phone and you have no idea how its work, you didnt read any reviews, that mention how this 4k work on z5p, and now you registered on XDA, and made topic IN WRONG SECTION about it.
Also maybe you could read USER MANUAL how superior auto mod work on camera? Its nothing hard, its in that box that you get with your phone :]
The phone goes into 4k mode when you are looking at 4k content (so 4k pictures and video etc). There is no need for 4k when you are looking at normal apps as that would just kill your battery and give you no visual benefit whatsoever.
As for the camera by default it shoots in 8mp but if open up the camera app then click the gear icon and then click resolution you can choose what MP you want. I recommend 20mp for best overall quality.
maybe you should read some reviews or watch review videos on the phone before you buy a phone :/

Camera Super Pixel 63.5 MP photos on Lg v10

Hi guys I just want to share with all of you a new app for all lg v10 phones It take photos with a resolution of 63.5MP on our V10 i saw this thread on nexus 5x and tried on my v10 and it works flawlessly I'm not part of the development of the app . It's on the Play Store here https://play.google.com/store/apps/details?id=com.anforapps.camerasuperpixel
good one to share , thank you

I appreciate you sharing this and all but...... The V10 camera is capable of producing a photo that is 5312 pixels x 2988 pixels, that has 16 million pixels in it. That is the maximum that the sensor is capable of producing. They are not ever REALLY going to be able to increase it 4x without physically changing the camera sensor. You can modify the dimensions of the image all you want, but the sensor just cant do any more than 16mp

You cannot change the sensor size, but you can get different number of pixels with the same sensor size, you have 23 Mp phone cameras with same size sensor, or smaller, than others with 12 Mp, like the last Samsung and Huawei, etc...
Having said that, you dont get more info, just 4x more pixels extrapolated from the original. The photos do look sharper, as I confirmed with my tests, but when I resize them to same size, they look the same, and the files are so large they wont load to apps, or be resized like on facebook and look the same again
Bottom line, only worth if we want to make a large print or display in a large hi-rez screen

The point I was trying to make (although maybe not all that well), is that you CAN increase the size of the picture, you can make it 100000x160000 and have a picture at 16GP, but if the sensor is only capable of capturing 16MP, you're going to have a pixilated image. Even with some very fancy software work.
With the actual resolution the V10 is capable of taking photos, they can be printed out to large format or displayed on any large monitor without ANY issues at all. (I have a 12mp DSLR and have printed photos up to 4ft wide with EASE)
I guess I'm just calling BS on what is really being accomplished and the expectations that are being set that the app is going to "Get your 16mp camera shoot a 63mp photo"

You are right. This superpixel camera gives a fake better image. I taken the same image in the same condition with the original V10 H961N camera and with the supercamera, analysed both in paintshop after magnifying and the details in supercamera are very dissapointing. Uninstalled without regrets.
My Sony NEX6 camera has a much larger sensor than the V10, but the same 16 Mp resolution...
I am not saying this app will have 4 times more detail, but dividing every pixel in 4 blended with the pixels around, if properly done, will increase sharpness, as I confirmed with my tests.
Having said that, I will not use it, not worth what we loose on features
The results are real, the app is using a well known photoshop technique but in-app.
Olympus is also using it to up their resolution on their e-m5mII camera.

I recommend having a look at cortexcamera. It uses a similar "trick", but increases the size by only 50%. The result is a stunning 24 MP photo with almost no visible noise and lots of details with no adverse affects from noise reduction. There are a number of limitations though that are basically inherent in the technic. It's best used for rather static scenes and between shots the phone needs a couple of seconds to calculate the resulting image (combined from up to 100 single frames). That being said especially for night or landscape shots I find the results impressive.
Using the Super Resolution Method does not add any more details. Of course it is limited by the sensor. But by doing this, noise is greatly reduced and artifacts like Moire get removed since the program averages the images. This method is done by professional photographers if they want to enhance images when using a mid range shooter.

There are certain benefits upon doing this 4x Spatial Reso Increase. The details don't bump up so much but noise gets significantly reduced and edges become much more detailed rather than edgy. Still its an improvement than nothing. Tho the hype should be re calibrated.

Exactly this. I was just about to mention the OM-D E-M5 MII. This camera has a 16MP sensor but has a 40MP high-res shooting mode which combines eight exposures into a single image which is how it can manage to get such a high pixel count out of a sensor that's only natively capable of 16MP. You and your subject would need to be completely still though as any movement can create blurs and jagged lines but the results are real, there is a noticeable difference if you look closely.
But that's if you look closely. Having a high pixel counts doesn't mean much unless you need extremely large prints and even then, have you guys seen the huge billboards from Apple saying that the picture was taken with an iPhone 6 or 6S? That's a 8MP and 12MP sensor respectively. Of course, they probably edited the pictures like there's no tomorrow but then if you were going for such huge prints, you probably wouldn't be printing directly from the in camera RAW or JPEG file.
As a hobbyist photographer, I would say learn the manual settings in the built-in camera app. It's more than enough to squeeze the best possible pictures you can get out of the V10's camera. Then go out and buy yourself a MILC or DSLR (but MILC is probably the smarter choice).
thanks for posting this app

Don't lile it
Image processing is way better in stock lg cam app
Yeah pixel count does not matter much. 16mp is plenty for most pics. Unless the program managed to use the ois in here to emulate what the Olympus OMD EM5 Mark II does I dont see how it would get a actual useable larger pixel count without the possiblity of introducing digitial artifacts in the image. And even then unless you were shooting non moving subjects in a studio environment you would get that ghosting effect in the pics. Id rather just take regular shots in Raw and post process if I need to work the pics some more. On a side note, the 5 axis OIS on the Olympus is very Nice. I agree with a previous poster about learning what the manual controls do. Then get a nice camera if you are serious about taking better shots.

Grainy and pixelated photos when you zoom in in a photo viewer on desktop

I recently noticed that, when zooming in after a photo was taken (on my desktop, full HD monitor, using Google Photos or Irfan view), the quality is really really bad, I can see the pixels and looks grainy. Granted, the pics were inside but the light was decent.
As a comparison, the quality of non-zoomed it of photos taken in the same condition with my old LG G4 is worse, but when I zoom in on those to a similar level there's way less grainy effect and visible pixels. Zoomed in they look considerably better compared to the G7. All photos were taken on Auto.
Not a photography expert, I just point and shoot, it's very possible I am missing something. Tested on my wife's G7 and it's the same. Am I doing something wrong? How's the quality under similar circumstances for you? When you zoom in. that is.
Thanks
Try the gcam app.. Stock camera app is sacrificing details for sharpening the image
Like djfready said... Gcam for some real magic
https://www.celsoazevedo.com/files/android/google-camera/f/cstark27_GCam_5.1.018_24_v4.2t2.apk
Post the photo on gdrive or something so we can see.
