Re: -- now with stabilization -- ρcam raw/jpg camera application for N9 and N900 with manual controls
 
Please clarify, did disabling DNG fix the problem?

Re: -- now with stabilization -- ρcam raw/jpg camera application for N9 and N900 with manual controls
 
I'd like to request a timer feature to help making timelapse videos.
Logic would be: Take total of n photos at x resolution at interval of y seconds.

For example so I could take 3600 images of 854x480 at 1s intervals.

Can someone recommend already existing app for this N9? I just bought Fastmotion pro and it fills the ram+swap until the OS freezes, which makes it unusable.

Edit: Being able to have files named sequentially eg. img000001.jpg, img000002.jpg, .. would be also useful. Ability to toggle screen blaking is probably a must to prevent screen burning and useless battery drain.

@qwazix, please changelog for Rawcam 1.0.4 Maemo?

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
rawcam 1.0.4
* Fixed the creation of the DCIM folder which was accidentally commented out
* Fixed the accelerometer based stabilization to work in all conditions
* Added a combined Accelerometer&Burst stabilization mode
* Now N900 version is again on par with N9
* N900 when quitting by closing lens cover still inhibits the regular camera from working until reboot. Currently only workaround is to go to switcher and press the x button.

Get harmattan binary from my repository and fremantle from extas-devel

I was hoping I could incorporate the function of the fremantle application lowlight into rawcam but unfortunately lowlight is not open-source. I found however this pdf which explains the algorithm. I don't know if I will find the time to decipher it, but if anybody wants to help you are very welcome to provide pseudocode for this, and I will include it in rawcam.

@Ladoga, I remember that there was a way to capture camera frames with gstreamer on the N900, specifically screen-sized ones. Writing a shell script to run the command should be trivial, and the command should work on the N9 too. This fulfills all your requirements and is easy to implement. I suggest you search for the relevant command and if you are not familliar with shell scripting, start a new thread asking for help. The result will be useful to many people.

Now it's time for a shameless plug :)

I was on a nokia exhibition stand and they had a "dark room" so that potential customers could compare the Lumia 920 with their mortal cameraphones, so I took the bait and tried my luck with rawcam and the N9. Here's the result
L920http://play.qwazix.com/photo_compari...121122_019.jpghttp://play.qwazix.com/photo_compari...4.18.48.22.jpgN9

Now the comparizon isn't completely fair because I just snapped with the L920 and I tried several times with different settings with the N9 to capture the second image. On the other hand that dark box was tailored to suit the L920 camera (thus the better whitebalance).

The L920 photo still looks better, but it seems they've gone the Kodak/Canon way and they've applied a bit more post-processing otb. It seems like some of the details have been lost (too much NR). Unfortunately I didn't take a raw picture with the N9, only JPG.

So I applied some quick steps of enhancement in gimp and got an even more close result. (Meaning that with a little optimization on the software side we can almost match the 'amazing' L920 camera)

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
Thank you qwazix for making rawcam! With the Shutter speed priority, and the Manual mode's spot focus it might just be the only digital camera I will want to use. I love it!

I have 2 questions:
1) does the rawcam behave differently with and without a screen protector? I already have the protector on when I installed rawcam, and wonder if the controls will feel different without it. If so I'll take it off.
2) When it says to "cover the proximity sensor to focus" is it for all types of operation whether AF or MF ?

Thanks again!

qwazix 2012-12-10 20:18
Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
HLing, thanks!

I don't know about the screen protector, I don't use one, maybe a fellow user can help you with that.

About the focus: Short answer: autofocus only. Both full-auto & point.
Longer answer: I hated the lack of camera button on the N9. The default way of focusing, press to focus release to snap is a major way to introduce camera shake because it's a transition from a stabler to a less stable situation. Let me explain. On a real camera, in low light conditions the best way to operate is to hold the camera as stable as you can, half-press to focus, wait for the best moment, the one you feel most stable, press the button and keep it pressed (that is why the cameras have a seperate burst mode instead of always bursting when you keep the button pressed, even if at first thought it makes sense). The movement is from a loose grip to a firmer, while on touch-only phones it's from a firm grip (right thumb pressing against the screen) to a looser where the right side of the phone is practically in the air while the snap is captured. When you try to capture one-handed it's even difficult to not drop the phone, let alone take a steady picture.

So I decided that the best thing to do is to provide a separate focusing mechanism, and covering the proximity sensor can be done without blocking the viewfinder, and easily when holding the phone with both hands.

Arie requested to include the default touch to focus functionality too so that came in an update but is disabled by default on the N9. On the N900 it's of course enabled as we have a real two-step camera button. However you can still pre-focus with the proximity sensor anyway.

In manual mode the focusing is controlled by the slider only (except if there is a bug)

Would you elaborate on what is the exact problem, maybe I could help with some ideas or code.

EDIT:
Going to give it a try.

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
Thanks freemangordon for stepping in.

Detailed description of the closing problem on fremantle:

In rawcam, I have a trigger that when the user closes the camera lens cover the application quits. I have investigated the problem pretty thoroughly and I thought I had all the right things before closing. Obviously, this is not the case. In my code you will find many qDebug's printing messages in various stages of the exit process because of that.

After closing this way, if you launch camera-ui it quits before being able to show the viewfinder with
Code:
Internal error. Application 'camera' closed.
When I am testing the latest version rawcam segfaults at the latest stage of closing, but during trying to fix the issue this wasn't always the case, but the problem remained the same. I had managed to prevent the segfault but I was still getting a
Code:
QThread destroyed while running
in the console. As I was just trying to fix the issue and my changes broke the N9 closing sequence I reverted to the segfault situation.

On the N9, and when you ctrl+bkspc -> close on the N900, there is no such problem.

More info:
Fcamera (which works as intended) uses this code to handle the closing sequence
Code:
  // Connect the threads together in a daisy chain to get them all
    // to stop and then quit the app
    QObject::connect(cameraThread, SIGNAL(finished()),
                    &IOThread::writer(), SLOT(stop()));
    QObject::connect(&IOThread::writer(), SIGNAL(finished()),
                    &IOThread::reader(), SLOT(stop()));
    QObject::connect(&IOThread::reader(), SIGNAL(finished()),
                    &app, SLOT(quit()));
full listing here

My relevant code:

Code:
    //when the lens cover closes stop the camera thread
    QObject::connect(cameraThread, SIGNAL(lensCoverClosed()),
                    cameraThread, SLOT(stop()));
    //and show a message that we are about to shut down
    QObject::connect(cameraThread, SIGNAL(lensCoverClosed()),
                    closing, SLOT(show()));
    // Once the camera thread stops, quit the app
    QObject::connect(cameraThread, SIGNAL(finished()),
                    &app, SLOT(quit()));
full listing here, lines 405 - 415

I have also made my custom app class derived from QApplication so that I can reimplement the quit function to make sure all the threads have quit before quitting the app, but with no results.
Code:
void RawcamApp::quit(){
    qDebug()<<"preparing to exit";
    cameraThread->wait();
    delete cameraThread;
    delete overlay;
    QApplication::quit();
}
full listing here

Despite all of the above if there are images in the pipeline to be saved, and somebody closes the window (currently the only way to exit on harmattan) the app quits forcefully so I needed to include the following line after the app.exec(); clause
Code:
while (cameraThread->writer->savesPending() > 0) sleep(1);
Thus the app stays open without gui until it saves all images.

Actual console output in the current version
Code:
stop false
preparing to exit
out
Segmentation fault
* code on github is one version behind, but there are no changes to any of the relevant parts. Latest source exists in extras-devel, and I will push one of the next days to github anyway.

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
Hi, I have a n950 and I installed rawcam 1.0.4. When I try to launch it I get a black preview and the user interface on top. When I take a picture (although it is black on the preview before taking it) the picture is saved and is not black.
Is it the viewfinder problem mentioned in the first post?
How can I solve this black preview problem? could it be a dependency problem although I checked that everything required is instsalled. (I also tried versions 1.0.3 and 1.0.0 and it is the same)
Thanks!

qwazix 2012-12-11 07:36
Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
It's not a dependency issue.

Unfortunately the N950 uses some kind of different overlay so I cannot make it show anything, I tried whatever could pass from my mind without sucess. I managed to get some different results like green window and totally black (without GUI) but no real picture.

Although, the picture is taken, the colors are wrong, as showcased n the first post. This problem requires reverse-engineering the fcam drivers and fixing N950 support. One dev from #nemomobile tweetes that he did that but I haven't contacted him.

This task is up for the taking. For now my priority is fixing N900 support and adding some new things.

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
Hi there,

Just a small remark, is it just me or the focusing bar became much less responsive on the latest version? It used to work flawlessly before but now i have a hard time trying to move it. In general all the sliders became less responsive.

Also as an idea, would it be possible to add a quit button and lock the app from swiping away (like emumaster does)? It is a bit annoying when trying to use the sliders just to find out that i closed the application instead. Just an idea.

Anyway thanks a lot for the app, it really makes taking photo a much more enjoyable process!

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
Hi qwazix,

Thanks for the update, a slight issue i noticed was the automatic white balance, tends to sit on a lower temp, making the picture more whitish/bluish specially in indoors with low amount of light, manually adjusting can fix it almost immediately. but automatic accurate white balance is much proffered,
Also the 16:9 still captures in 4:3 ratio, not a big issue though.


//nkirk

edit : i'm using n900. my apologies for the inconvenience...

qwazix 2012-12-11 12:05
Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
@nkirk and everybody reporting bugs, please state the phone you are using. (I didn't test the 16:9 thing on N900, I supposed it would work as it does on the N9)

@jmsarriat I didn't mess with the slider code in the last version but it might be a sideffect. I will consider locking the swipe event.

Plus, is anybody using PR1.2? I'm trying to publish to the Nokia store and it keeps getting rejected, I'd like some help if possible.

i have to say this cam app is getting really impressive. I just tested the new version against the stock camera. i cranked up everything the stock camera can offer(nightmode,iso 800,exposure compensation to max) to take a picture of a pretty dark alley.
for pcam i didnt touch anything...just automatic and a steady hand.
i dont know how to upload the pictures...hope you can see it.

thanks alot for this app:)

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
I tried it without the screen protector, big difference in the ease of the sliding bars. I now have to decide since I have already gotten a couple of light scratches from before I got the nice carrying case....

Thanks for your reply. I totally agree about the general difficulty in taking a picture with a touch screen, WITHOUT a physical button for shutter.

I'm still a little confused about the symbol of the circle surrounded by two parenthesis that's on the upper right hand corner area, between the AF and the MF. Do you mean that IT isn't a function in N9?

So far the best way for me to use the camera is to have the left menu ( P S I M ) selected on M, so that i can chose my Shutter speed and ISO independently, and then on the upper right (AF (0) MF) selected on AF, and it seems that I have pretty much all the control I'll need, taken into account that the preview may be a little brighter than the outcome.

Today though, the rawcam is making clicking noises, and I'm getting a lot of horizontal blue lines all over the picture, which are on the actual dng file.
https://lh4.googleusercontent.com/-k...0.46.03.34.jpg

Also, I had problem with darkened video play back that didn't go away until I reboot.

Anyhow, just thought I'd share. I trust that the bugs will go away :)

Thanks, n9cell.

HLing, I have to investigate the thing with the lines now that it appears to more than one user. Please try reinstalling to see if the problem will be solved (PhilG13 reported that after a reinstall the problem goes away for a while). The darkened video thing should be fixed in 1.0.4, are you using that one?

Re: ρcam 1.0.4 -- raw/jpg camera application for N9 and N900 with manual controls and image stabilization
 
HLing , yes, I have the same issue with horizontal lines. Unfortunately, reinstalling the app didn't really help. I still see them from time to time, usually when shooting something at night. Still no idea what causes them, although I remember that the early versions of rawcam did not have this problem...

I've tried gst-launch (that's the only CLI method I found after quite extensive searching). I had N9 to take stills using the main camera as video source and wrote those over ssh to my laptop.The results were quite poor and blurry.

What I meant was a way of taking good quality photos (not video stills) to make time-lapse videos. (Or should it be called time-lapse photography?). Even if I can find a way, I expect that adjusting composition, focus, exposure and iso level are better done in a "real" program rather than shell scripts. I enjoy writing shell scripts though. :)

Anyway it's not terribly important and I've found a so-so replament as CameraPro app has ability to take timed photos. There are few down sides to it. The display will stay on when the app is running, which could be be days so I'm bit afraid of screen damage and it hogs a lot of cpu (90% usage, while capturing 1280x720 images at 2sec intervals) so the phone has to be plugged into a charger. Otherwise it does the job quite well.

Count me in with the horizontal lines issue. I suddendly got them the other day. In a room full with electric engines. Actually the lines were kind of in phase with the engines, could it be some sort of electromagnetic interference? Standard camera app had no problems though.

I own an N900 with power kernel 51 and cssu thumb. I have a serious problem even with 1,04. After using rawcam and exit screen colours get a little bit mess and normal camera could not start. Restarting solve the problem . Is the fcam drivers that cause the problem or rawcam? (blessn900 does not have such a problem).

Qwazix, I've installed 1.0.4 on both the 16G and 64G (it's a good thing I have two N9s temporarily to trouble shoot.) I've had both N9's on the same rawcam versions: first 1.0.3, then 1.0.4. I've not had problem of horizontal lines with the 16G N9.)

Today when I first opened Rawcam on the 64G N9, I can already see a lot of the horizontal lines on the screen. I closed it. Checked and compared settings with the 16G N9. Then opened the stock camera app on the 64G, the screen looked fine. I then opened Rawcam, and yay! No lines!

As for the video being darken, I had the problem with the 1.0.4, but after reboot I opened the video player to play something (back to normal) , and then I opened rawcam again to take pictures. then exited. then played the video again, still fine. no darkening. I've not had problem with it since.

Maybe it is sharing resources somehow? I don't know enough about the technical stuff. I'm just glad there's a work around because..Rawcam rocks!

I think the nokia repo is down again and the phone can't download the dependencies, but on the other hand, on PR1.2+ no deps should be downloaded. Anyway try again later. Latest version for N9 is 1.0.4

If you don't want to bother looking for the latest version and don't mind risking a broken version once in a while you can add my repo.

If you want the latest stable you can add rzr's repo. It's a bit outdated right now, but I will import 1.0.4 there soon.

By the way if someone still is on 1.2 I need some help. (on N9, that is)

actually, regarding some of the earlier report on the final image being darker then stock, i notice that the center of the image have a normal exposure, but as it gets towards the side of the image, it will have more blueish color, suspect this is due to the post processing..

I have uploaded an image on the attachment, it's taken from N9, using 1.04 that i have just installed.
Hope that helps :D

It is an effect called "Vignetting" and is sensor derived. Post processing can remove it and indeed photos from the stock apps tend not to display it for that reason. Search the forums and you will see much discusion of it concerning the n900.

IIRC vignetting is mostly lens related and it happens as the lens is not able to give even amount of light to the sensor's edges. (same ofcourse applies to conventional camera's film) If you look at very old photographs they often have strong vignetting.

In camera (or phone in this case) processing is not very good anyways as it has only small fraction of time and resources compared to doing the same on a powerful desktop with good image manipulation software. So I guess we are better off removing vignetting from raw images.

Of course it is :) Seems I have an occasionally paradoxical relationship with my brain.....

Hi,

I've been testing 1.0.7 with my n900, no problems so far.

Only minus is that I would like to choose different location for *.dng files (external sdcard). Is that possible ?

Not as is, but I can do that in an upcoming version. No promises though.

P-mode seems to behave differently depending on last mode used.

When pcam starts, P-mode is active. Shutter is usually 1/30 (and changes only if ISO goes to max) and ISO number changes rapidly depending on what is seen on the screen.

When I change to I-mode, ISO number is fixed and shutter changes - OK. If I now change back to P-mode, ISO number stays fixed and shutter speed continues to change. So it is same as I-mode, but sliders are gone. P-mode is fixed by switchin to S-mode and back to P-mode.

I didn't see anybody else complaining about this.. ?

impressive work!

Once installed, rawcam only displayed a gray screen instead of the image. After reboot, version 1.0.7 is working on my n900 (just a little freezing problem due to live focus app).

thanks and congratulation for your work

Good catch. Essentially confirmed. Not entirely sure of what mode sequences do or don't work - M seems to get it stuck again. However P should definitely always seek the lowest iso at a sustainable shutterspeed (that seems to be the case at startup).
