I know that the two rear cameras have FOV (field of view) of 135 (the wide one) and 75..
The lg g6 has 125+71 and the front is 100 degree FOV.
Can any one say whats our lg g5's front camera FOV?
Thanks!
edit:
The Answer is 75 degrees
Here you are the view angle and other useful informations about the three cameras, according to what is reported in /system/etc/camera/camera_config.xml file.
Rear normal:
<FocalLength>4.42</FocalLength>
<FNumber>1.8</FNumber>
<TotalFocusDistance>5.25</TotalFocusDistance>
<HorizontalViewAngle>67.4</HorizontalViewAngle>
<VerticalViewAngle>41.2</VerticalViewAngle>
<MinFocusDistance>0.1</MinFocusDistance>
Rear wide:
<FocalLength>1.53</FocalLength>
<FNumber>2.4</FNumber>
<TotalFocusDistance>5.5</TotalFocusDistance>
<HorizontalViewAngle>119.3</HorizontalViewAngle>
<VerticalViewAngle>78.6</VerticalViewAngle>
<MinFocusDistance>1</MinFocusDistance>
Front:
<FocalLength>2.6</FocalLength>
<FNumber>2.0</FNumber>
<TotalFocusDistance>3.76</TotalFocusDistance>
<HorizontalViewAngle>69.3</HorizontalViewAngle>
<VerticalViewAngle>55.0</VerticalViewAngle>
<MinFocusDistance>0.1</MinFocusDistance>
Nice! Thanks for that!!
But, I don't quite understand these numbers.. they don't follow the numbers on lg website..
How does these practical numbers:
horizonral FOV: 119.3
Vertical FOV: 78.6
Match the theoretical number of 135?
Neither Maximim or square root give such number..
If any one can pure some info that would be great
Have you tried to look in your rom the same file? I'm using a rom ported from the LG G7, maybe some values have been left there from the G7.
I don't know how to calculate solid angles, but I think that 135 is the angle measured as if the diagonal of the rectangle is the width of the angle.
Checked on my stock ROM (rooted).
Same numbers..
(*) Written square root I meant diagonal calculation..
√(119.3^2+78.6^2)=143
I don't think Phytagoras can be used in this case, as we are measuring the diagonal of a rectangle projected on the part of a sphere drawed by the solid angle. Phytagoras is valid for rectangles drawed on a planar surface.
I tried to measure it myself..
heres the planning sketch:
View attachment 4641098
and here's the measuring results:
View attachment 4641088
all pictures were taken from a constant height of 98.5mm
so the results are:
H = 98.5mm
rear normal:
L=65mm, W=120mm
which brings:
vertical fov: 36.5
horizontal fov: 62.7
rear wide:
L=150mm, W=280mm
which brings:
vertical fov: 74.6
horizontal fov: 109.7
These numbers are different from both the config file and the published data on LG's website..
What went wrong? or why the numbers aren't equal?
edit:
I tried a similar measurement comparing the normal rear camera and the front camera..
They are equal so I can confirm that the front camera has field of view of 75 degrees
I don't really know. But why do you need such a precise measure for the view angle?

It seems like the camcorder is much higher quality, seems odd, since it's coming from the same lens. Even just switching between the two, the camcorder doesn't have as much viewing angle, and everything seems much sharper.
Anyone else notice this?
I have noticed it.
Wider angle = more in the picture = lower quality.
It's the same 5mp camera for both the camcorder and camera but since the camera has a wider viewing angle, more is in the picture at once and it decreases the relative resolution.
Unsure how it has a wider viewing angle, it is the same hardware.
My camcorder video always comes out looking nicer than my photos, even after I lower the resolution on the photos to 1280x720 after the picture is taken. The camera should natively look nicer on the small screen, since it's a larger resolution snapshot.
You probably just aren't holding the phone as still as you think you are. Try resting it on something stable when you are taking pictures if possible. Also, make sure you are holding down the shutter button to focus before you let go.
Done this, camera appears more blurry on the display even before taking a picture. Camcorder appears much more sharp and vivid.

The camera does not have a fixed lens, it can focus and zoom. When the camera is being used, the lens is at it's widest angle possible. Since the camcorder would not be able to process that wide of a video fast enough in 720p, the lens has a shorter viewing angle (aka wider focal length).
I'm big in photography so I'm speaking from knowledge of cameras and it may or may not be the same on cell hpones...but I'm pretty sure it is.

Partially correct, the camera physically moves to focus, but it's not changing the viewing angle. http://www.newscaletech.com/phone_camera.html
The resolution is changed within the app, it just crops the image. Camcorder is just likely sampling at a higher rate so there's less noise, and the stock camera app on the atrix is terrible.

The term "fixed lens" is ambiguous, since it doesn't specify which aspect is "fixed."
The Atrix camera module has a fixed focal length lens (i.e. not a zoom lens), but it is not a fixed focus lens (i.e. it has variable focus, in this case autofocus). The "zoom" function is just digital zoom, electronically cropping the image.
In video capture mode, the camera is cropping a section of the sensor, rather than using its full area as in still camera mode. (This increases the apparent focal length of the lens, but it's not actually changing the optics.) The video mode probably does this so that the resolution in the portion of the sensor used is a regular multiple of the video capture resolution, which can greatly simplify the image processing requirements.
Regarding the OP's original question, the viewfinder image appears sharper in video capture mode, but if you actually capture still and video images of the same scene, the still images are sharper. The better looking viewfinder in video mode is probably a result of the same reason they only use a cropped section of the sensor. It's like if you view an image in Photoshop at 25% size, it looks great because it's easy to scale the pixels that way, but if you view it at some usual magnification like 43%, it looks fuzzy.
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.

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.

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.

I would like to have some image effects on the 3D pictures... kinda like HDR and Vintage or Black and white 3D pics.
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.

I first noticed that my optical x3 photos had a fair bit of digital noise to them.
I then tried pinching to change the zoom and I couldn't see any transition between the lenses when going from 2.9x to 3x. You should be able to clearly see the transition between 0.9x and 1x
After covering up all the lenses one by one with my finger and changing the zoom level, I can see that the x3 view (which should be using the bottom left lens, as you are looking at the back of the phone) is only blocked when I cover up the standard lens (top right)
Can anybody else verify this? Is this some strange intentional behaviour or a bug?
Confirmed on my device too as a bug when viewing the screen.
However, if I try taking a photo the camera switches to the 3rd sensor to actually take a photo.
Must be a new 'improved feature'.

IMHO I suppose it's so by design, to allow the user for a smooth zooming experience, and it can be considered a bug only as far as the correct lenses are not used to take the final picture.
I think it's to do with the minimum focus distance to be honest. If you're trying to focus on something far away it will switch but something close it will switch back.
I think, the camera changes at zoom 3x if there is enough light, otherwise it will use the main sensor. I tested this by holding the camera on TV and on my low board, the room was dark.
Samsung's s10 series has a field of view of 123 degrees, for the p30 pro, it is only 107 degrees, is FOV hardware based? or this can be changed through software?

This is based on focal length of the lens.
Ultra wide lens is equivalent of 16mm FOV in 35mm camera, which is 107 degrees.
This cannot be changed in any way, because this is physical parameter of the lens. Only possible solutions for bigger FOV would be:
1. To stitch a panorama from more shots.
2. To use wide angle converter in front of the lens.
Hello there, this is dedicated to all my photographers and videographers of LG G8x.
First things first, no matter what how many times you complaint them the problem is not fixable through software updates because front camera have fixed focus.
So i think there is no other option than this.
Case 1: (Professional phone photographers)
Guys if you are carrying a 35mm or 50mm then mount it to the front camera and zooming 1.5x is the solution for shooting 4:3 aspect ratios and only 1.2x zoom for 9:16 or higher aspect ratios.
+ Get lot of blur or shallow depth of field.
+ Can use Canon or Nikon lenses to achieve high end quality. Plus features if your lens have OIS, UV protection etc.
- Weight is a problem.
- Zooming 1.5x makes photo to loose its quality a little bit (especially in nights).
Case 2: (Cheap solution)
This is an inexpensive solution, get yourself a wide angle lens for under 200 rupees for indians and under 2 US dollars.
Buy that 3 in one lens and use the wide angle and zoom 1.2x for 4:3 aspect ratio and 1.1x for 9:16 or higher aspect ratios.
+ Very Cheap
+ Light Weight
+ Less zoom means lesser quality reduction
- No quality lenses are used, little bit lesser color reproduction.
Buy anywhere online by typing 3 in 1 lenses for phone.
Hope this would help you out, if helps don't say thanks but help me find a solution to record 1080p 240 fps video with zooming (stock camera doesn't allow zooming in that setting)
Filmic pro is not working for slow motion .
Moment pro camera doesn't work for slow motion.
Google Camera doesn't record slow motion.
Suggest me a way to do this.
Thank you for all the patience.

why you actualy need to zoom ,just crope the video after recording done ,using a video editor.
our device didn't have an optical zoom even in photo mode if we zoom 8x it just uses its digital zoom.
you just click a pic at 8x and same pic at 1x then you crop the 1x pic to 8x then compare 8x pic vs croped pic. result will be same:fingers-crossed:
give me a like, i gave you a solution with best explanation
I appreciate your idea but actually thing is when you film it with no zoom and crop it later, same results i agree. But you won't get the flexibility of knowing what exactly you ate shooting, you can't see the full sized video as a reference while shooting.
1) You barely see the depth.
2) Hard to manage White balance and Exposure.
I do need some other working apps that would support this phone zooming while filming at 1080p 240fps.
Tried many of the popular apps
Google Camera, Filmic Pro, Moment pro camera, Proshot, Hedge camera 2, (MiUi 11 Camera, Oneplus Camera- Stock).
