Reverse camera video is very zoomed in. Can i zoom out? - Android Head-Units

My reverse camera video image seems to be very zoomed in with my MTCD unit. Does anyone know how to zoom out?
Maybe it is the camera that makes this zoom, i don't know.

Its the camera. What you need is a very wide angle "fisheye" lens camera. A typical dashcam is a fairly narrow view designed to just grab a person's face and neck.

Thanks bud!

camera video quality

I took a couple of videos and the quality to me just isn't that great. This is with the UHD setting. Just isn't that clear for UHD.
I agree I had lots of noise/grain in mine. FHD60 seems a bit cleaner
This is a pic zoomed in half way. Looks awful. I bought this phone because the camera was supposed to be unreal. Is this normal or just maybe I have a bad cam?
Shot some video in a dark bar venue of a band playing. Using the main lens and manual settings, it turned out really well. The wide angle left a bit to be desired as shot but I think I have an idea for that lens. Shot with 1080 at 30fps high bit rate. Posted it in another thread over the weekend.
And at full zoom
Shot at 1080 30...

Looks as though you may have a dirty lens.
The light in the room is a give away of grease or finger prints across lens. As the ceiling light starts to chase across your shot.
Same thing can cause grainy pictures. As it effects even a camera shot the same way.
Always try cleaning the lens if the shot seems to be poor.

I've tried to clean the lens, no luck. Do u think it's the phone itself?
Did you set to record in high bit rate?
Personally, I think the camera, both video and still, is the weakest part of the phone. I am not happy with that, but will live with it until the Note 8 comes out.
And you removed protector of the camera lens?

What other settings did you use? (ISO, Shutter Speed, Bit Rate, Filters?)
I will say that it looks like you're using the digital zoom, which is always problem #1. Never use digital zoom unless you have to do so. Whoever came up with this gimmick should be dragged out into the street and hung. It just doesn't get you anything but a mess. Optical zoom is optimal. Bipedal zoom is your secondary option. Digital zoom just shouldn't be an option. It is quite literally the option you choose when you want to have some sort of shot, any shot, and you don't care about the quality of the shot. This goes for any device from a cellphone up to a DSLR.

This was shot in a very dark bar venue with mediocre stage lighting. (Strike one against getting decent footage.) ISO 3200 (Another strike against any decent footage as you're maxing out the gain on the sensor.) 1080 at 30fps so I used a shutter speed of 1/60. I used the high bit rate setting. The refocusing is me touching the screen as I couldn't tell if I had good focus since it was dark and my eyes kinda suck these days without readers. I was playing with the audio settings and had no idea how to set it for a concert so I cheated and used approximately what I found for concert settings in the HD recorder app.
Considering the conditions..... the V20 did extremely well! I could pick things out in the audio that I couldn't live in person. In person, it was just a wall of sound sometimes. The video turned out amazing for being a tiny camera sensor. The only real thing I can knock the V20 on is the video stabilization. There needs to be settings somewhere so I can turn the OIS and EIS off and on so I know if it is on or off.
Are you using the stock cam app? I don't see anything where I can change the zoom type.

Yup, stock camera app. There is no setting for changing the zoom type. If you aren't clicking the one tree/three tree buttons, then you are going through a digital zoom. Only clicking those two buttons uses purely "optical zoom" although in reality, you're just completely switching cameras. (Different sensors and different lenses which presents its own issues since the wider view uses a smaller sensor and smaller aperture while the main shooter uses a "larger" sensor and larger aperture.)
Using pinch to zoom or the zoom slider means you're going through digital zoom. So if you start at the widest setting with the wide view and start zooming, the image quality is only going to get worse until you pop over into the main imaging group. Then if you continue to zoom, the image quality will degrade again. The best quality you're ever going to get out of any single focal length imaging assembly (which is what we're technically dealing with here, two single focal length imaging assemblies) is at its native focal magnification and at its base ISO. Which the photo options says is 50 but that's not always necessarily true, I'd have to look up the native sensor ISO online to be sure.
Did an unprocessed and processed test with my v20. By far the best dynamic range of any phone camera I've worked with.

The only positive thing I found about the digital zoom on the v20 which is unique in my experience is that when you're shooting 1080p on other phones, even though it's a 4k sensor it zooms up on the post sampled 1080p frame instead of taking advantage of the 4k sensor and zooming up without any quality loss. The V20 appears to do just that and up to a point there's no fidelity loss with the digital zoom because you're sampling a smaller section of the sensor..

Don't remove that. It helps protect the glass from scratches and shatter.

Did you gain any insight to help fix your grainy pic issues? I'm having the same problem. I keep seeing people suggest to remove the plastic protector but it has cutouts for the lenses and the sensors so I don't see how that makes a difference. I'm taking pictures without any zooming but when I take a look at the results and zoom in to different parts to review, it looks horrible and grainy.

What is your photo size set at? 16mp or 12mp?

I haven't. I wouldnt take the plastic off. As you said, it has cutouts for the lens. Not impressed at all with the camera
I'm amazed at your low light video. I also thought the camera was the weak point of the phone. Guess I need to work on my manual focus skills.

Can you use the wide angle (back) camera to take selfies?

Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.

which camera mode resolution......

I personally think the wide angle lens is amazing..that is until you zoom in at all on a picture after it was taken now if considered taking them in 4:3 to get a true 13mp camera thinking that would result in more pixels equals better chance of retaining image quality. Please post all thought thank you
Zooming with wide angle at full resolution or cropped result in the same inkyness. Wide angle isn't really for zooming.

I mean taking a photo in wide. Going into gallery than zooming in on that photo

Is my front facing camera ****?

Gidday folks, just got this awesome new phone but I'm incredibly concerned about the front facing camera... See my attached pics and let me know.
Excuse the ug face...
The front facing camera on the G6 isn't brilliant. To get the best possible image quality from it it's best to use the wide angle setting as the zoomed setting is just a crop of the wide angle image.
The front camera is definitely one of its weak points though.

Don't know why LG reduced from 8mp to 5mp to the front camera? Use the rear wide angle camera and use it for selfies.

Why is my front camera zoomed in when recording a video?

Dear people from XDA,
My front facing camera records video's heavily zoomed in. Like my face fills the whole screen. This is while using the default camera app.
I do not have this problem when taking a picture with my front facing camera.
I have seen problems with snapchat and instagram, but I also have it with the default camera.
OnePlus support says i gotta clear cache, but that doesnt work. Now they tell me to do a factory reset.
I got the latest software update for the Oneplus 6T.
Any of you have this problem?

Its probably to do with image stabilisation, it crops out the edges as that gives room to adjust for shaking. I could be wrong, but thats something I did for a dummy project before, I think its a pretty common practice thing

This is the case when taking a picture, but not when recording. It doesnt work.

Like he said.. When it's in video mode, it appears to be zoomed in because it's cropping the edges as part of the electronic stabilization.*
I'm not a hundred percent certain on that being the explanation but I am pretty confident. That's just the way it works and I just open the app to be sure and there is no way to turn off this stabilization
I don't think it's as much about image stabilization as just aspect ratio. If you go into the selfie picture camera and change the aspect ratio from 4:3 to full screen, the image will be similarly zoomed in. As I understand it, the camera sensors are 4:3. To get 16:9 or 13:6 full screen images, it just basically crops the 4:3 image and stretches or zooms it to fit the desired size. Just like when you take an older 4:3 SD tv show and zoom to fill a widescreen tv.
I'm just speculating though, so I may be off base, but it makes sense. I'm sure someone will correct me if I'm wrong.
It is the electronic image stabilization. It crops the recorded area to leave room for the frame to move around, so that it can compensate for movement.

Interesting. Thanks for clarifying.
