Re: camera-ui2 testers needed (updated 13.03)
 

If I had any clue how to install this I'd totally help. I have a quick question though regarding the DNG output you alluded to. Is the output similar to FCam or more like stock N900 camera output? The reason I ask is that the FCam output is incredibly difficult to profile because of color shift around the edges of the image where the image shows vignetting. Somehow the N900 stock camera app doesn't display any vignetting or color shifting on the edges.

Re: camera-ui2 testers needed (updated 13.03)
 

just extract it, and put it on under /usr/bin

Re: camera-ui2 testers neede
 

That may not be a flaw. I work with camera chips at work regularly, and know a bit about them. It may be that the upper/lower lines are actually masked lines (sensors with a black coating over them). Why would you do that? There are lots of reasons, but one of them is to help gauge how much drift you're getting and "noise" on the sensor. If you look at them, are they actually black (0), or something close to it? If it's the later, they're probably masked lines.

It may also be that the chip is not in the right mode. To get those masked regions sometimes the sensor itself has to be put into the right mode to report them back (vs just using them internally for row noise balancing and such). The cam developers at Nokia may have just gone with the default setup and let the pre-packaged module handle the dirty stuff for them. In that case, the code for putting the module into full-frame mode may not even be in there, even if it were open-sourced.

Great work on this. I haven't installed it myself yet just because I like having at least one stable camera. Lots of the ones I have around seem to be in various states of hacked, and I'm not willing to give up the one reliable one right now. :)

I did and got a segmentation fault

Re: camera-ui2 testers needed
 

I was sure I did this right, but you are right, when rotating the device
clockwise 90 degree the exif orientation tag was wrong.
And fixed!
And I added a new keyboard short cut b/B for switching between
back and front-camera (only in *video* mode).
See attachment in my first post.

The z key changes the zoom but the zoom slider doesn't slide as it does using the zoom rocker. Likewise, sliding the slider doesn't change the zoom.

I like those key commands very much. Makes macro focus muuuch easier as macro autufocus can be finicky.

Perhaps focus could be f 1, g 5 or 10 & h 50?

kudos!

Re: camera-ui2 testers needed
 

The /apps/camera/settings/basic-settings/device-id
is a 25 byte random number.
And the classification id is made as follows:
Concat the 25 bytes device-id with 25 random bytes, and then compute the
sha1 hash of this 50 bytes. This results in a 20 byte hash key.
The classifcation-id is
20 byte hashkey + the above mentioned 25 random bytes!

Re: camera-ui2 testers needed (updated 13.03)
 

Are you sure you stopped the stock camera-ui before
trying to launch this one?

Nicolai

Re: camera-ui2 testers needed (updated 14.03)
 

i have tried using the dsmetool command way and just replacing camera-ui with your file both give me instant reboot, just replacing gives me the reboot loop.

am i going about this all wrong? am i best just leaving it for more experianced users?

Re: camera-ui2 testers needed (updated 14.03)
 

Regarding dsmetool: I have found that I get a reboot if I try it on the n900 x-terminal BUT if I ssh in (as root) I can get it to work. I once had problems via ssh but I got it to work after the reboot. Since then, I have been able to use dsmetool via ssh to unload and reload between camera-ui and camera-ui2 at will.

What happens if you "dsmetool -k /usr/bin/camera-ui" as root and then try to run camera-ui2 from the terminal as user? (Note need of path to executable - I forgot to mention that first off until I read Nicolai's response...)

Re: camera-ui2 testers needed (updated 14.03)
 

you are the man thanks a lot i'll give this bad boy a test

Re: camera-ui2 testers needed (updated 14.03)
 

I run it from command line.
It isn't ready yet to replace the stock camera-ui. Please don't
use dsmetool. But I must admit, I don't had any reboots
when I used dsmetool.
First, be sure the stock camera-ui does not run.
dsmetool -k /usr/bin/camera-ui
then you can start my app with
dsmetool -t <where ever you put it>

Btw the stock camera-ui in /usr/bin/camera-ui isn't the real
application, but a link to /usr/bin/maemo-invoker.
When you start /usr/bin/camera-ui maemo-invoker
is started and starts (depending on the name of the link)
an application (/usr/bin/camera-ui.launch).
camer-ui.launch is the real camera-ui "application". It isn't really
an application but a shared library with a "main" function.
maemo-launcher now loads the shared library and calls this
main function.
This is how the maemo application framework tries to reduce
the start up time of the stock applications (modest, mediaplayer ...)

Re: camera-ui2 testers needed (updated 14.03)
 

how can i install the application ? the file inside the .tar file doesn't have an extension

Re: camera-ui2 testers needed (updated 14.03)
 

It does not need an extension - untar it and that is the executable. You can run it from the command line as "./dir/dir/camera-ui2" the dir/dir bit being the path to where you have the executable. Or cd into the directory and "./camera-ui2" will do the trick. BUT, as Nicolai shows above, you first need to remove camera-ui from contention using dsmetool.

Re: camera-ui2 testers needed (updated 14.03)
 

thanks Nicolai i was using the dsmetool -k /usr/bin/camera-ui cmd in root and the dsmetool -t /usr/bin/camera-ui2 (where i unpacked your file) but this was causing a reboot. so i did as handaxe said and ran your file in user not root and it works.
i've got to say what i have seen it looks good works quite well.
i have found auto video mode is a litlle eratic in lower light levels the colour style short cut works well while recording.

Re: camera-ui2 testers needed (updated 14.03)
 

would running it like this cause problems?
nohup ~/bin/camera-ui2 >/dev/null &
I haven't seen any absurd effects on CPU ever since you updated it the first time. dsmetool -t always crashes for me :(

Re: camera-ui2 testers needed (updated 14.03)
 

I don't know.
Have you used the full path
dsmetool -t /fullpathtobinary

And of course, you can make your own .desktop file:

Re: camera-ui2 testers needed (updated 14.03)
 

i have noticed on after each photo is taken the transition from camera to the captured image has the open lens cover screen.
also when in front facing camera i need to restart camera to get back to the main camera.

does the front cam need extra software/drivers as it seems so dark?

Re: camera-ui2 testers needed (updated 14.03)
 

Yes, I will fix this.
Yes, capturing images with the front camera does not work. I added
the front camera only for the video mode, but I missed to
disable it when you change back to image capture mode.
No, the front camera is just bad in low light environment.

Nicolai

Re: camera-ui2 testers needed (updated 17.03.)
 

Updated (see first post).

Fixed
- no "lenscover screen" in transition to the preview window.
- zoom key z/Z updates zoom slider
- switch back from frontcamera to backcamera when scene mode
changed to image capture mode.
- recorded videos are now in "recorded from device" category
- start image viewer/mediaplayer button in preview window
opens the image viewer/mediaplayer with the last taken image/video
(in the prior version the image viewer/ mediaplayer was just opened)
- preview window closes after deleting the image/video

Thank you for your feedback!

Re: camera-ui2 testers needed (updated 17.03.)
 

nicolai, i got "permission denied" when i typed :
/usr/bin/camera-ui2
after disabling the stock camera

Re: camera-ui2 testers needed (updated 17.03.)
 

@nicolai the f/F short cut on focus seems to be disabled but the g/G still works

Re: camera-ui2 testers needed (updated 17.03.)
 

@AgogData
This happens, because you have untared the file on the
MyDocs partitition (which is a FAT partition and doesn't know
anything about user and execution rights)
You have to set the execution bits again:

chmod a+x /usr/bin/camera-ui2

Re: camera-ui2 testers needed (updated 17.03.)
 

As it is an increment of 1 it is quite subtle. I too had some trouble testing but did best trying to change focus with f/F at around the macro distance. But perhaps there are issues...

I would like an intermediate focus jump but that may not be technically possible.

Re: camera-ui2 testers needed (updated 17.03.)
 

its awesome nicolai, i'm gonna use it insted of the stock one..but here is my experience :
- after launching it and opening the camera it was like the stock untill i lightly pressed the camera button, the camera-ui2 settings appeared.
- when i switch to video and pressed record it gace me the stand by screen and switched back to the stock camera or at least the camera-ui2 settings were removed.

Re: camera-ui2 testers needed (updated 17.03.)
 

so this supports front camera now?

Re: camera-ui2 testers needed (updated 17.03.)
 

You *have to* stop the stock camera-ui before launching
this one. They both react on lenscover and focus button press.
They don't work nicely together.
Video recording only.

This version is extremely experimental. Use the keyboard shortcut
r/R to toggle between raw image mode.
When raw image mode is enabled it stores an additional DNG
file with the raw image data.
This is really experimental I am not sure if this DNG
is valid. Some image tags are wrong or missing.

As noted here http://talk.maemo.org/showthread.php...358#post964358
There is a bug in a gstreamer component and therefor
some lines at the image bottom are missing.

Re: camera-ui2 testers needed (updated 17.03.)
 

Unloading the default camera-ui is what running as root should do. As Nicolai writes, that must happen for you to be successful.

Re: camera-ui2 testers needed (updated 17.03.)
 

Thats what i did :
- dsmetool -k /usr/bin/camera-ui (root)
- /usr/bin/camera-ui2
xterm says its working ----> then i open the menu and choose camera
BUT when i type
- dsmetool -k /usr/bin/camera-ui2 (root)
it says [can't kill or not found, though its working]

so is it a matter of camera-ui not being stopped ?

Re: camera-ui2 testers needed (updated 17.03.)
 

The DNG develops OK in rawtherapee, ufraw etc. The exif shortcomings are probably tolerable if they prove not to be correctable.

tnx

Re: camera-ui2 testers needed (updated 17.03.)
 

No, you should not use "dsmetool -k /usr/bin/camera-ui2" as you never loaded camera-ui2 with dsmetool. When you have closed the x-terminal you can check what is running by typing . There should be no camera-ui2. If there is then type . Then as root, you type . This re-establishes the old default camera interface in a way that will have it auto-reload if it crashes etc.

Re: camera-ui2 testers needed (updated 17.03.)
 

They are correctable, I am just too lazy to implement it now :-)

Nicolai

Re: camera-ui2 testers needed (updated 17.03.)
 

thanks for the great camera app nicolai, i've created an beequeen widget to disable camera-ui and enable camera-ui2, so when i restart my phone i can activate it with one click :)

Re: camera-ui2 testers needed (updated 17.03.)
 

Oh yeah! As the preceding pages show, lazy is a real big problem for you ;).

I assume that RAW is a relative term here, as there clearly is processing done to produce the .dng. For instance, there is no vignetting of the sort that is so prominent in fcamera and thus clearly is a feature of the sensor.

Re: camera-ui2 testers needed (updated 17.03.)
 

I can't seem to get the RAW output. I use the keyboard and toggle r and no change. I only get the JPG image. I am using the latest build on the 1st post. I also tried the binary linked here

Re: camera-ui2 testers needed (updated 17.03.)
 

Was the DNG file just in the same DCIM directory? I did a "find . -name *.dng -print" but haven't found the files and I tried toggling 'r'. Do you know if the DNG files work on Lightroom? Would be interesting to see how well LR's NR / demosaic algorithms work on these files. I like FCam but the vignetting and color shift around the edges is horrible.

Re: camera-ui2 testers needed (updated 17.03.)
 

R - enable raw image mode
r - disable raw image mode
:-)

Re: camera-ui2 testers needed (updated 17.03.)
 

Nicolai...Amazing!

Re: camera-ui2 testers needed (updated 17.03.)
 

I had already tried R and tried it again just now but still don't see any RAW files in the DCIM directory.

Re: camera-ui2 testers needed (updated 17.03.)
 

just a suggestion. how about a multi-shot mode? it takes like 3-5 pictures at one shot, then you can pick the best one and delete the rest
