[Q] Camera sizes on EVO 3D - HTC EVO 3D

Hi all,
I have installed Elixir 2, i'm not sure which one to use. On clicking on information and then on the device tab, one of my camera's says it has a resolution of 2560x1920 focus length 3.49mm and the other is 3840x1080 focus length 3.49mm, the front camera says 1280x1024 focus length 2.2mm
Can anyone tell me what this means please.
Cheers.

The rear upper camera can take 4.9MP images and the rear lower camera can take 4.1 MP images. Through according to me the cameras are capable of taking maximum of 5MP images but the software is made like that by HTC .
And the front can take images of 1.3MP

Are you saying thats what all EVO 3D's can do or what mine can do? Because they're not all the same in terms of hardware.

All Evo 3Ds that I came across have same camera as yours............and also all the main parts of the 3Ds that we talk about are same for all. Just the SoC is different in CDMA and GSM and also the Wimax/sim card part.
Else every CDMA and Every GSM phone is same (some parts might be region specific)

Evo 3D app ideas [share yours]

What would you like to see/think would be cool/only possible with the Evo 3D?
1. Dual focus images: Not sure how well this would work or how well the effect would even be perceived, but independently focus each camera when taking a 2D image (obviously requires someone to figure out how to use both cameras in 2D mode). Possibly result in a easy Tilt Shift photo.
2. 10mp image: Doubt this one is even possible really, but stitching an image from each camera together.

#2 won't work.
5mp+5mp doesn't = 10mp
10mp would be like taking the first 5mp shot and attaching the 2nd 5mp shot by a corner to one of the corners of the first shot.

Assuming the boxes with the 1's in them are 5mp each, a 10mp box would be made by making lines enclosing the 2 other boxes - where the X's are.
With the 2x5mp cameras, you'd only have 1/2 the data necessary to create a 10mp picture.
Technical talk aside...
I think it would be cool to invert the 3-d...
To take a picture of someone's head and "pop it inside out" so that their nose was the furthest point AWAY from you, rather than the closest.
I don't know if this would be as simple as swapping the two images or not - so the right displays on the left and the left displays on the right.
Nothing like playing with someone's mind by inverting the way they think the world is and showing it to them =D
Kalah, 5mp+5mp does indeed equal 10mp. Your way of thinking is a little skewed though. The pictures would come up essentially the same way the 3d pictures will be displayed on the phone normally (ignore the - signs, they are just for formatting since the site will delete extra spaces):
111111-222222- 121212121212
111111-222222- 121212121212
111111+222222=121212121212
111111-222222- 121212121212
111111-222222- 121212121212
The picture doesn't show a larger area, just a higher pixel density. The problem is this will only work for distant photos as they are taken from just slightly different angles.

Alright... Kindof.
You can get 10mp across, but your vertical resolution wouldn't increase. You'd get some really wide pictures.
To double the size of a photo, you have to quadruple the pixels... Not double them.
I'd love to see some great high quality 3D Augmented Reality apps that incorporate 3D. I'm sure there would be good money interactive 3D AR. I know it's cheesy and all, but those little pet games are very popular (personally not a fan). One thing that I would find absolutely fantastic is an app that allows you to draw or create cool 3D shapes in AR. When you close out of the app, all your drawings save and when you open it again you can continue creating awesome stuff and building an alternate digital reality splattered with your creativity. And it would be vital to add in a feature so you can add friends so you can share your world with them.

1) both images are offset as they are taken from different points, wouldn't work
2) again, different angles of the same image, wouldn't work

turn the phone upside down
or, open the mpo file in something like "stereophoto maker" (freeware), press "x" (swaps images round) and save the new mpo file back to the phone. (am sure there will be an app to do this eventually)

Again, you don't really understand what "megapixels" means. It is already width x height in the picture. Example: 1000 px x 1000 px = 1,000,000 px or 1MP
If you double one dimension, you double the MP of a photo. I didn't say you made it "twice as big." Yes, I agree that when people say twice as big they usually mean twice the height and twice the width, which is really 4x as big.
on to a different camera idea i just thought about.....
you know when you try to take a picture inside of a moving subject and it always blurs due to lights and ****. wonder if you could make an app that fires the cameras a split second from each other and you can choose one of the better pics

You could also do something like this (ignore "-" sign):
11111 - 22222 - 1*1*1*1*1*
11111 - 22222 - *2*2*2*2*2
11111 + 22222 = 1*1*1*1*1* -where each "*" is a virtual pixel value, which is
11111 - 22222 - *2*2*2*2*2 -approximated by taking some sort of average
11111 - 22222 - 1*1*1*1*1* -between the neighboring (left right bottom)
---------------- *2*2*2*2*2 -top) actual pixel values.
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
---------------- 1*1*1*1*1*
---------------- *2*2*2*2*2
simplest approximation would be * = (right + left +top + bottom)/4.
Using two camera for 2d shoot can have only benefit in focus and sharpness, because 80% of picture is same on bouth cameras
The 3D is nice and all, but the dual camera seems like it ought to have real potential:
1) HDR (High Dynamic Range) photos
2) Accurate? distance measuring
3) 3D model generation
4) Facial security for lock screen - 3D based, so can't be faked with a photo
5) "Corrected" 2D photos - use the differences between dual photos to filter out artifacts? Better low light photos / night vision?
6) Action shooting (alternate cameras for faster snap shotting?)
7) "Hand" lock screen? (take a 3D photo of your hand, to unlock your phone?)
Just throwing stuff out there I haven't a clue on how to actually create any of those, or even if they're possible.

Try fast burst camera from the market. Doesn't use both camera's but takes pictures quite fast.
New idea?
i thought creating 3D icons... and use the 3D cam. to create a wallpaper of the image the camera see in 3D in combination i think that looks cool.

3D Video Chat!
We already have 3D video recording so something like live video chat does not seem like too much of a leap. Most video chat programs don't support the front camera of the Evo4g let alone the Evo3D. Having a program that specifically targets the Evo3D for 3D video chat would be an amazing feature to compliment this awesome phone.
Cheers!

What video chat apps don't support the 3D's front camera? Yahoo, Tango, Fring, Skype, and Qik all do, that only leaves Oovoo. Plus the front camera won't do 3D, it wouldn't be video chat, you could stream live in 3D though.

EVO3D has 5MP 2D images or 5 + 5 MP = 10MP 2D images?

If I remember correctly, I thought the EVO 3D's 2D images were supposed to be 10MP because it combined the two 5MP lens into 10MP. If this is true, then why are all the reviewers just saying the EVO 3D takes 5MP 2D images?
where did you read that at?
It doesn't work like that because of the different view angles of the camera. unless they can make a program as amazing as the human brain with our eyes, then they can, but only 1 camera works in 2D. Maybe someone can play God and give us the somewhat 10MP you are thinking of. (doubtful to the point that i can nearly say its impossible)

that was some idiot acting to be an HTC rep... spewing fantasy... 5MP 2D... It uses the top camera.
I still don't get how , if you could activate both cameras for 2D, if you take a 5MP picture you get a 10 MP photo. You would get one super bloated , file wise, 5MP picture.
If you could just take 1 picture and keep adding it to it's self to increase mega pixels I would do that all the time when a customer sends me a crappy photo to enlarge and manipulate. But adding 2 of the same photo does not increase the mega pixles. in this case 5+5=5

I know you're joking but the bottom camera is more in the center of the body which would translate better with framing pictures with the screen. I would have preferred the bottom camera myself.

[Q] Why evo have 2 5mp cameras?

Specwise the Evo 3D is having 2 5MP cameras on the back. But some websites say that the Evo 3D captures 2D images in 5MP and 3D images in 2MP (correct me if I am wrong).And in 2D mode The Evo 3D uses the upper camera to take photos and videos.So the camera below it can be 2MP instead of 5MP.Then what is the need of the having 2 5MP cameras instead of 1 5MP and the other 2MP.
I'm lost with what you said...but I will try..to many damn numbers...so the pictures will be of equal resolution since you can take 3d pictures at 5 mp.
It is in deed strange, why can't E3D take 5MP 3D pictures. Maybe there will be a firmware update in the future who knows.

I think it has to do with the processing power to "combine" those two separate pics into one 3D image. You think the camera was laggy before, try waiting for the CPU to stitch together 5MP images...
I thought the camera take 2 seperate pictures and use parallax barrier to make one preceived as depth, aslo E3D has more processing power than ordinary point and shoot 3D cameras.
From what i have read the Evo 3d takes 2 x 2mp pictures in 3D mode and links them together to get 4mp.
Regardless of that, the phone takes great pics in 2D and 3D.
Love that dedicated camera button..no more yoga finger stretches to tap on screen while trying to keep steady..
Simplest answer may be the best answer... It was designed as having to take a 2MP 3d image because of how the screen displays natively.
Why 2 5mp cams? Because they are cheap and identical, from the same manufacture and they could only use 1 cam assembly Chinese kid instead of 2 to install 2 different non alike cameras. Allows them to just buy 1 sensor in greater bulk than 2 model sensors. Hence, cheaper to produce.

but the indian GSM evo 3d have the upper 5MP and lower 2MP cam
Think of 3d as blue ray It's twice the SIze of the file. And it seems I get 5 mp in both. I miss the og EVO camera. And panorama. In windows there was a hack in the registry where we bumped up from 3.2 mp, to 8 mp in panoramic. Up too 7 stitches. Problem is we ran out of memory for more than 3 stitches. I miss those options.
Sent from my unrooted EVO3d
There's many Roms that add panorama camera mod. And there's a ROM that claims it boost camera up to 8mp but I havnt tried it myself

3d photos

Hello,
have anyone found a way to capture 3d photos? Facebook has rolled out 3d photo capturing for dual camera phones, but I don't think g5 will get that feature.
I use phogy but it's a bit old and outdated.
In order to take 3d photos, we would need two identical cameras. The two cameras of our phone are too different for the view angle and for the sensor size and quality.
The software would need to know how to deform the wide angle photo to make it look like the one taken with the main camera, and I think they still would not match perfectly.

Well, you can still get 2d image + 3d depth mapping from different dual camera. LG g7, v35, V40 (with matching 78° & 107° camera) will support this Facebook 3d format soon

Poco F1 Front Camera Fix New Finding

Hello devlopers and friends Ever since I brought poco f1 and installed gcam and other third party camera apps my front camera resolution drops to 5mp. Only official camera app is able to use 20 mp resolution.
I know there are many threads about pixel Bining and stuff but i don't agree with them. The main problem is at the end a 5Mp Image is 5Mp and 20 Mp is 20 mp.
But i think and request devlopers to please look to it.
## According to my theory As confirmed by Device info Harware app There are three camera sensors in poco F1 out of which the one with camera ID 0 is 13 the one with camera ID 1 is 20 and with camera ID 2 is is 5 megapixel.
"
13 Mp back camera primary Camera Id 0
5mp back camera primary camera Id2
20 mp front camera Id 1
"
According to my theory the five megapixel and the 20 megapixel camera are conflicting with each other and gcam is taking the values from 5 megapixel instead of 20 megapixel sensor. So I request that developers that they can try I and confirm if it is the case and if it is true please make a fix for it
thanks
On specs sheet, the front facing camera has 20mp but in gcam it says 5mp. Google Camera is using what they called "Pixel Binning" and it is a software implementation.
This process is the procedure of combining a cluster of pixels into a single pixel. As such, in 2x2 binning, an array of 4 pixels becomes a single larger pixel, reducing the overall number of pixels.
13mp back camera is the main camera shooter
5mp back camera is the depth sensor
20mp front camera is the secondary camera shooter
One good example is this

Thanks for replying
The question is that why gcam and other apps detect only 5mp sensor.
Lets agree gcam uses pixel Bining and stuff.
But why other apps detect and capture 5mp are they all using pixel Bining.
And why only Mi Camera can capture at full potential of the sensor. Is there a catch we all are ignoring.
Pixel Bining or not at the end when zoomed 5Mp image is storing lesser data .
And also imagine a 20mp full resolution shot with gcam cam make things go from OK to wow.

It doesn't really change anything. And it doesn't mean more resolution = more quality. It is a matter of fact of image processing. If you really compare MIUI Stock Camera and Google Camera, you will see the big difference from the two since that Stock Camera doesn't uses Pixel Binning algorithm

Pixel binning gives better shots in low lighting conditions only. No significant difference in well lit conditions. Thats why i want to capture with full resolution in Google camera because its awesome.
Also if pixel binning is so justified why don't we capture 3 mp photo with rear camera and say its better than 13mp because its not
Justified ( That 20 mp shot from miui cam is not good than gcam)
Not justified ( That it is due to only pixel binning . It is due to google computational algorithms.)
#pixelbinning is justified only in badly lit photos not everywhere
Agreed doesn't mean More resolution=more quality
But More resolution =More information per inch in captured shot ( in case of gcam it means awesome shot)
More resolution =More information per inch in captured shot ( in case of miui camera it means ok shot cause it does not uses multiple shots and algorithms to produce good shots)

Then use the stock camera if you really wanted the 20mp. Use gcam if you wanted better image processing.
This was explained a long time ago and it is really not a big issue or some conspiracy about the 20mp sensor
Yes it is a issue One plus devices had this issue Zen devices had issues similar in Auxiliary camera regarding resolutions on gcam. All those were fixed due to efforts of devlopers.But i think people just want to accept everything and not work it out. If some one can try to find a fix there will be a fix. But if everyone just accept the fate lie down nothing is gonna happen
Similar issue, i can't change photo camera resolution on miui 11.0.5.0.

Dude, you are suggesting your gcam is taking front selfies with rear 5MP sensor?
A 20MP image is only twice as big 5MP image. Not 4 times big.
Gcam 5MP selfie carries much more details than 20MP MiUi camera, day or night. Period. MiUi camera does a lot smoothening.

Or maybe gcam does lot's of sharpening to make them look "detailed" zoomed out? When zoomed in you can see tiny coloured squares.
Update I used Redmi note8 Pro and Redmi k20 pro with gcam They all produce 5 mp front and 12mp back irrespective of the sensor resolution. Maybe gcam only supports these resolution maximum.
Honestly i would love larger resolution support with gcam .
In k20pro gcam can take images in 48 MP resolution
In back But issue is in front it only takes with 5mp resolution and this 5MP resolution is useless when you zoom the image or see it laptop you can see amount of noise.This really need a fix .
Can i disable Pixel Bining
I think no devloper is interested in This.
I wish there were devs who would look at it but sad thing is no one really care
True story
Actually Gcam detects full one Megapixel when individual pixel size is more that 1.1 π size..
Poco f1 or other Xiaomi phone with 20mp sensor has individual pixel size of 0.8/0.9/1.0 π size.
But Gcam detect full 13mp in my Redmi note 5 AI because the sensor's pixel size is 1.12 π.
Thus even in my old device has a 13mp insane Gcam selfie.
