Develop Bugs

Looking for camera source code

I have written my own video recording/streaming application and needless to say I believe there are many undocumented calls being made by native camera application in order to get around resolution restrictions, etc.
Default android sdk doesn't allow for anything other than QVGA to my knowledge...yet native camera app has no issues with mpeg4/720p, etc.
I have looked at htc kernel source code but I don't believe evo custom source like camera is in here...am I mistaken?
I would really like to see the special magic done by native camera app.
Thanks in advance...mike.

Hey,
Excited to hear you're diving into this. I wanted to add my 2 cents as to potential improvements: give us the ability to turn OFF the auto shutter / exposure settings on the video camera.
The video camera drops shutter speed and increases exposure in lower light situations - resulting in blurry and pretty much unusable video in dark situations. 8 FPS? ew.
I will be first in line to buy a video camera app that gives me full manual controls (or at least gives me steady FPS in light / dark situations, and manually adjust exposure (like iso).
Thank you, and GOOD LUCK!!

Found it in git...never mind.

Camera app with potential - Camera VF-5

Guys,
I’ve just stumbled across a new camera app called Camera FV-5 on the play store. It might not be something for everyone, but if good support for the One X could be implemented – I think it has a lot of potential for people with a photographic background.
Would really like to know what people think before I contact the developer.
Here's the website:
http://www.camera.flavionet.com/
Bugsy

Here are a list of features (Copy/Pasted) from the Play Store description. I will mention that the RAW feature isn't RAW as such - it saves the final image in lossless PNG format instead of Jpeg.
• All photographic parameters are adjustable and always at hand: exposure compensation, ISO, light metering mode, focus mode, white balance and program mode.
• DSLR-like viewfinder display: see exposure time, aperture and stops display with EV and bracketing settings.
• Full fledged exposure bracketing: from 3 to 7 frames, unlimited stops spacing, plus custom EV shifting.
• Built-in intervalometer: make stunning timelapses (even bracketed/HDR timelapses) and time-controlled picture series.
• Program and Speed-priority modes.
• Long exposure support: take beautiful night photos and light trails with long exposure times up to 60 seconds*.
• JPEG as well as RAW (PNG**) image formats for lossless photo capturing, perfect for post-processing.
• EXIF and XMP sidecar metadata support.
• Self timer for delayed shooting.
• Autofocus, macro, touch-to-focus*** and infinity focus modes, plus a focus lock switch (AF-L).
• In background photo developing and processing allows a smooth, uninterrupted camera operation.

looks interesting will give it a go

Sorry, I didn't see that.
Edit: Now I see why. I started my thread a couple of weeks or so before that thread was made

Since the thread is made, another that I use and is worth checking out is 'Shot Control' no PNG format but produces better reproduction of the scene in my opinion, particularly the colours and exposure.

But it is a camera app not a recording app correct?
I think the camera on One X is fine for images just the recording that needs to be improved.

Thanks, I'll take a look.

For a quick comparison between the stock camera, FV-5, camera 360 and camera ICS, check out my quick review for more info.
http://forum.xda-developers.com/showthread.php?t=1652642

I'm definitely going to check this out. The camera was the reason for me getting the HOX so i'll dive in.
Will report back shortly.

you should try lgCamera (lite in playstore and pro from the internet)
you'll get a photocamera and videorecorder
you get better photo's, 4,5mb instead of 1,5mb of HTC (less compression, better quality)
with videorecorder you can get smoother movies with nice sound,
- you can set bitrate till 100mbps, but I think 20mbps is enough (the SIII uses 17mbps for 1080p, htc uses 11mbps) so set it to 20mbps, for smoother movies
- record in stereo at max 320kbps with 48hz
- record in 3gp or mp4, but mp4 is better for the One X

[APP] Camera FV-5 - camera app with user customized exposure time

Hi,
this app works on my HTC One X.
The first app with working user customized exposure time (attached pictures)!
Camera FV-5 > Google Play
description said:
Camera FV-5 is a professional camera application for mobile devices, that puts DSLR-like manual controls in your fingertips. Tailored to enthusiast and professional photographers, with this camera application you can capture the best raw photographs so that you can post-process them later and get stunning results. The only limit is your imagination and creativity!
Major features:
• All photographic parameters are adjustable and always at hand: exposure compensation, ISO, light metering mode, focus mode, white balance and program mode.
• DSLR-like viewfinder display: see exposure time, aperture and stops display with EV and bracketing settings.
• Full fledged exposure bracketing: from 3 to 7 frames, unlimited stops spacing, plus custom EV shifting.
• Built-in intervalometer: make stunning timelapses (even bracketed/HDR timelapses) and time-controlled picture series.
• Program and Speed-priority modes.
• Long exposure support: take beautiful night photos and light trails with long exposure times up to 60 seconds*.
• JPEG as well as RAW (PNG**) image formats for lossless photo capturing, perfect for post-processing.
• EXIF and XMP sidecar metadata support.
• Self timer for delayed shooting.
• Autofocus, macro, touch-to-focus*** and infinity focus modes, plus a focus lock switch (AF-L).
• In background photo developing and processing allows a smooth, uninterrupted camera operation.
This camera application completely avoids scene modes, instead you get full manual control over all photographic parameters, just like you do with a reflex camera, so you can ultimately control every aspect of the picture, and leave the post-processing to the computer. So after your DSLR, you will never miss a photo opportunity again, being able to capture it with the closer sensation to your DSLR as possible.
If you find a bug using the application, please, visit the web page http://www.camera.flavionet.com or write to [email protected] with your phone model name and the description of the problem, before writing a negative comment. Customer satisfaction is my priority, and I will try to fix it as soon as possible!
* Long exposures lowers picture resolution to 2 or 1 MP, depending models. The reason is explained here: http://www.camera.flavionet.com/faq.php#long-exposure-resolution
** Lossless PNG saving is a memory intensive operation. Some devices might need to raise the memory limit for Camera FV-5 to save PNG pictures. See the FAQ here: http://www.camera.flavionet.com/faq.php#png-memory
*** Touch-to-focus available only on Motorola, HTC and Nvidia camera drivers, plus some Samsung drivers and other phones.

The only things the i change are the format and the light metering mode! You need to set it according to the pictures to take! Macro, portrait or landscape .. I don't like the jpg format because i came from DSLR! The negative side is the space for the photo! 12 Mb >>> 5 Mb!! But the quality is much higher!!
---------- Post added at 05:02 PM ---------- Previous post was at 05:00 PM ----------
Another thing.. To save space and don't have a milion of file, i only save the EXIF data!

thx, i will try now.

You're welcome! Keep me updated!

Just installed the free version, not even gonna bother trying it, the limitation on the free version is the stupidest thing they could have done, 640x480 max resolution, I want to take photos at it's full resolution to compare it with stock and other camera apps, can't make any sort of quality comparison with a 640x480 image.

Is it the app cannot support custom input of aperture ?
Thanks.

The camera has a fixed F2.0 aperture

RAW Support and long exposures

Hi
Does anyone know if there is a way to save images as RAW in the Moto Z Play?
Also, the manual (pro) mode allows you to change the exposure duration but this seems to be maxed to 1/6 - any way to get to longer exposure times?
Thank you.

No idea about the RAW support but if you want to take long exposure shots there are a few camera apps on the Play Store which should do the trick (Camera FV-5 Lite for example) but I never tried any so you may have to try a few in order to find something you're happy with.

Cheers! I've got Camera FV-5 installed and it does present longer exposure times, but I cant tell the difference between them and the stock camera photos. For example, photos taken in stock camera at 1/6 look the same as FV5 at 5 second exp. I don't have my phone to hand but will post some examples later.

I'm not surprised if there's no differences between the 2 but I thought you could make 30 seconds exposure shots with Camera FV-5 (which would surely make a difference with the stock camera)
About RAW support, from what I've read the Z Play doesn't support it unfortunately. You'd need the TrueZoom mod to get RAW support, which is quite an expensive buy.

Edit: Tried to save RAW with Snap but although it gives me the option I was not able to find a RAW image on my card...
I use the Snap Camera app from Playstore. It's extremely versatile and gives you tons of options and it has RAW support with our Z Play.
It needs some time to try out all options and find out the best for the phone and it also costs a few bucks (although there is a free version too). But I think it's worth it. For example it's also the only app I've found which let's you tourn of the denoise filter which is sometimes very helpfull when making pictures of landscapes which lots of details.
The interface is a little annoying at first but you can turn off everything and build your own interface with the free customizable shortcut buttons (settings - advanced - on screen settings).
It has also a good support on XDA.

Thanks for this. It's odd, camera fv 5 says the phone does not support RAW. ¯\_(ツ)_/¯
What really bugs me though is the exposure times. I'll give it a try to see what sort of image I get with a 30 sec exposure now.

IMG image - Stock camera with everything auto and exposure at 1/6s. Looks like garbage.
DSC image - Camera FV 5, everything auto and exposure at 20s. Looks like dark garbage.

If im not mistaken, Camera2API supports raw format. Whenever Lenovo finally enables it (Nougat?) we should be able to export to raw format.

I found that long exposure shots have a very limited use :-\

True it's not something you'd use everyday, but it would've been good to have this work as it should. The only other thing I can think of is that they've nerfed it on purpose so the camera mod sells.

Long exposure error in third party camera app

I cannot find any option to enable RAW in native camera app , and after trying 10+ pro camera app from play store , I'm not able to make the shutter any higher than 0.5 seconds ! Native camera app has max exposure time of 10 seconds..
Can you please help me regarding this problem ? And please suggest any camera app that can support long exposure in RAW format.
(Even budget phones like realme 7 has 32sec exposure time in RAW mode :| )
Model no. SM-M515F/DSN

gcam and open camera has raw option but you can only see the thumbnail of the image you have to send it to a pc to get the full res aand 0.5 ss is just a bummer I hope somebody can change that

Yes RAW option is there with many cameras.. but I want RAW with LONG EXPOSURE... That is the thing I'm not finding in any camera app ☹ .. I dont know why the native app can go upto 10 sec and no other app can go beyond 0.5 sec... What's the issue ?

The issue is its probably software locked or something

It is not completely soft locked, still usable when set exposure time manually. CameraCharacteristics#SENSOR_INFO_EXPOSURE_TIME_RANGE reports 0.5 seconds at max so all camera apps use it as max value for compatibility. However I don't know any camera app allows completely manual exposure times. Some gcam mods have exposure options for astrophotography mode, you can use them with raw but most of them have no manual controls.

Thank you for the info.
Isn't it possible to overwrite #SENSOR_INFO_EXPOSURE_TIME_RANGE to 10sec which is default for the native camera app.
And why only the native app has the access to 10sec max exposure? This is a huge limitation in my opinion for a phone that costs rs.23000/-

They limit available exposure time for stability or promote their most expensive devices. In this case it is not stability because stock app has 10 seconds, #SENSOR_INFO_EXPOSURE_TIME_RANGE reports 0.5. I think stock app uses CaptureRequest#SENSOR_EXPOSURE_TIME directly without looking at #SENSOR_INFO_EXPOSURE_TIME_RANGE. Third party apps can do same thing too but they need to ignore #SENSOR_INFO_EXPOSURE_TIME_RANGE and set exposure time directly. They don't do that because it will crash if device doesn't support desired exposure time.
Maybe they can fix it with custom roms or you can send a bug report to samsung developer support but I don't think samsung will fix this if this is not a mistake.
You can try nikita's gcam with astro mode for long exposure raws.

I think I have to wait till they add raw support to the native camera app.
In the meantime I'll use gcam as you have suggested..
But this whole "limiting basic functionality " thing for samsung is very very disappointing...
Even Realme/Xiaomi has it in their budget phones ..☹
