Hey guys,
I don't know if this has been requested before (cause it is pretty hard to describe the problem, therefore the search didn't really get me any answers) some of the users here in germany would really like to have a gallery, where you can save on which level and where you zoomed in into a picture.
For example, if you are sliding through all your photos etc. and you see something special so you zoom in, you wanna save that zoom level / Position for the next time whenever you view that picture.
The device we are talking about is an Asus Eee Pad transformer but I think other tablets would benefit from this feature as well as you tend to zoom in on 10 inch screens a lot to see all of the details e.g. of the pictures which were taken with a Canon/Nikon Camera.
So is there anyway to achieve this with already existing image viewers or could anyone implement it into an existing app?
Greetings
Hi there. I hope I'm asking this in the right place, but I have an interest in the inner workings of cameras on android, and how an app could control them effectively.
I have noiticed that most, if not all, android cameras have autoexposure hardwired on, and that this hardware autoexposure is significantly more effective than what is user controllable (brightness sliders and the like in camera apps)
For example, if you are sitting in a dark room, with a bright window. Now matter how low you drop the "exposure slider" in an app, the window will never come into the proper exposure range. Yet, if you actually look out the window with the camera, to where the outside world fills the viewport, the camera will automatically drop into the proper exposure range. This is odd to me... So the camera CAN expose down far enough to make the outside not blown out, but I am not able to control this?
The only explanation I can figure is the exposure on cell cameras works in a two step process.
1. Light hits sensor, sensor uses autoexposure to get the right range, all on it's own (we cant control this, or can we?),
2. and then the software gets the stream and we can adjust it slightly inside of the software side.
So I guess my question is... is it possible to edit step 1? Can we manually adjust the full exposure at the sensor level? I find most HDR apps to be very lacking on Android, and I believe this is the cause. The app literally has no access to change the exposure range. It can only adjust in a small range that is exposed to software after the hardware auto-exposure has done it's magic.
I have hope that this may be changeable, thanks only to one software I have seen that can.. kinda... adjust the hardware exposure. An app called Camera FV-5 on the market, if you go outside, get your exposure correctly, you can then choose AE-L for autoexposure lock, and then go inside and look out that same window, and everything will say exposed as low as you locked it.
If this is possible, that at least means we can allow/disallow the hardware auto-exposure. And if this is possible, maybe more control is too.
Thoughts? My goal is to make a camera app that fully controls settings such as these. At their full range. Let me know what you all think!
(Specifically I am on the LG G2, and would like to get hardware level exposure control on this model, but Id love to expand after I see it's possible, if it is)
Sorry if this is the wrong forum, I am new here. if so Mods please move it for me or let me know where it goes! Thanks!

As I have no idea how the camera is using the light sensor, the only logical advice I would give you is to browse the source code of the standart camera app.. Since Android is open source, I'm sure you can find something that helps you
The other way would be to write a very basic camera app that does not make use of the light sensor, and then see how much exposure is actually done without you knowing.

Thanks for the suggestion. I'll start by looking at CM's camera app.
Got the phone today, and after setting everything up I did some google cardboard viewing. Not sure if it was bad settings from the QRcode of that particular cardboard, but I kept getting double vision.
After searching on google I came across a post on oneplus one forums, on the oneplus.net website, and scanning that QRcode fixed it for me.
Link is: forums.oneplus.net/threads/fix-oneplus-one-google-cardboard-no-more-double-images
Thanks for sharing. What do you mean double images?
The way google cardboard (and all other aftermarket vr headsets) works, is by splitting your screen in half and then rounding each half into circular shapes to appear like you have full view.
Unfortunately each screen is a different width. Our eyes are at different distances apart and the glass in the headsets are all at different fields of view. This means that if you have the wrong setup, then the vr apps can place the images on the phone too far apart, too close together, or at the wrong angle (circular shape) to match your eyes and headset glass. So, for example, if the two images are too far apart or close together, your eyes can't twist enough and your brain can't combine the images into one. Think of it like crossing your eyes while still seeing distant objects as one. So thus you get double vision.
The provided qr code is nice to have. But depending on your headset, may not work. The best option is to use the link to the vr setup utility and use a computer to adjust the view until you have perfect vision with no eye strain (muscle tension)
Has anyone tried disabling NFC and using a Daydream as Cardboard?
I tried with a cheap eBay vr glasses and it works just fine. No problem at all
I love the 360 degree panorama mode - I had been thinking about buying a separate camera to take these kinds of pictures, but the inbuilt option on the camera works well enough and only misses a small area of the scene at the top and bottom which is no problem.
The only issue I have with it is that the panoramas come out looking quite dark. Normally this isn't an issue as you can do some quick touch ups in Google Photos but I've found this seems to remove the "pano tag" or whatever it is that allows the phone to recognise its as a spherical photo.
Is there an easy way to edit these photos but have the phone (and Facebook or wherever else you can upload these photos) still recognise that there are 360 degree spheres?
Thanks
Hello, I want to change the auxiliary lines for the reverse camera, in my rooted android HU.
Anyone knows where to find the reverse camera app directory? So i can change or customize those lines.
8227l / YT9216C Firmware.

The reverse camera is basically hard wired. When activated, the camera is sent directly to the stream. This is not managed by an app. I have had my Head unit in recovery due to corrupted blocks, and the reverse camera still worked.
Almost certainly managed by MCT unit, definitely not an app.

I see, so is there any way to modify this or not a chance?

It may be possible to rewire the reverse camera to use it for other purposes in an app, and it may be possible for an app to access the camera feed from the MCTX, bu tbh I don't know. It may also be possible to rewrite firmware for the MCTX.
However, it sounds like a lot of effort.
Maybe if you shared with what you are trying to achieve: "Changing the auxiliary lines for the reverse camera" does not tell us what you want to achieve by doing so, hence my guess about "using it for other purposes".

the auxillary lines are a little bit low res and plane,i just wanna change that to something cool, i created a .png but guess what now i'm stumbling to that wall of MTC thing.
the stock line are a little bet fuzzy too.
If there a solution i'm willing to try it,just it has to bee noob friendly hhh
P.C when i put the HU to sleep,it shows little size for time and date,is there a way to make that big too.

Still don't know what you're trying to do.
The resolution on the cam low, it is just an RCA on most android Head units AFAIK. Might be nice to have, but really - do you use it that much and does the blurry resolution stop it from serving its purpose? I wouldn't bother trying, as I'm not sure you'll get anywhere. I may be wrong...
When Android is asleep, the MCT unit will control the clock display and the reversing camera.
You might find an updated MCT firmware for your device if your searched for it. Updating is fairly simple, but DONT flash the wrong file!
Good luck.

I just wanna change the red yellow and green lines when I go reverse, the resolution of the cam is great but those lines...
My head unit has no name, how could I find the right file to flash, is those info would help :
8227l
Yt9216c AHD
8.1 go android (fake sine it have 23 api)
Mcu : 3.1
Thank you

OK. those lines.
Did you buy an aftermarket camera? My camera displays the lines as part of the video feed. There are options in some ROMs to overlay lines. Settings - Car ou Vehicle - Extras I think. You may be able to turn the lines on and off. However, if the lines are overlayed by the camera on the feed (like mine) you would need to replace the camera with one that does not have the reversing lines. Ask before you buy.
Do you have the possibility to plug the camera into anything else to check to see if the lines are present in the camera feed?

my cam is connected to a jack pinned to the back of the HU, it's my 2nd,and the auxiliaries are the same, when I go to factory settings I can add others with great resolution, but don't overwrite the bad ones, cause I still have kinda double auxiliary line the old bad resolution and the added ones by factory settings.
Is there an update file for my mtc with the info i posted?
Edit : a friend of mine had a bootloop once, what I noticed, the reverse view worked even though but with no lines, I guess the lines are rom related.
Hi Sorry to thread hijack, but i am having trouble even getting an image with my camera installed. I only get the lines. Mine is is an 8227l demo YT9213A. Is this the issue ? 1GB RAM model also. Tested 2 cameras and 2 vid leads

Go to Factory settings -> enter password maybe(8888) click on top parameter settings and it shows about the reverse lines
