Hi Marcus mentioned to me about a video I couldn't get too. Can you
let me know the URL to it? Now I have time ;-)
Thank you

Archive.ORG uses gphoto to scan books.... See here:

http://sourceforge.net/mailarchive/forum.php?thread_name=alpine.DEB.2.00.0811131742180.687%40utopia.booyaka.com&forum_name=gphoto-devel

They use some interesting machines (look at the movie intro at archive.org),
two 90 degrees angled glass plates that get lifted down to the book, picture
taken, lifted up again and the human operator pages forward. Repeat.

Ciao, Marcus

Re: scanning + OCR the monkey way ...

Hi everyone,

this is relevant to my interests too.

What I did so far was: Using gphotos remote control feature to setup an
A640 and taking pictures in a ~7secs interval. First taking all even and
than all odd pages. Afterwards using a shell script to rename them in an
appropriate way ... and doing quality control, page number checks, etc

To improve my setup, I have to improve the lighting situation. For this
purpose it would be ideal to use LEDs to illuminate the scene when and
only when the shutter is open. I saw, that gphoto offers the feature of
executing a hook script. I seems that there can be only one script called.

It would be nice to be able to let it execute one script when the
capture command is send (ideally, when the shutter is opened, don't know
if gphoto has this information) and another script when the image is
downloaded (just before, ideally immediately when shutter is closed again).

opinions, comments ?

and btw: there is a growing community working on the whole idea:
http://www.diybookscanner.org

Thanks and best regards,
Ingo.

~

Thank you very much. I am glad to see there are more of us culturing
these issues!

~

Why do you need to press the pages to be scanned against a glass? If
what is needed is getting the pages flat on the platform, I would go
first (faster I would say) with on side of the pages and then flip the
book and go with the other side. Even though the flipping has to be
repeated, I think it would be faster and safer to the user, as well as
less complicated and damaging to the books
~

> … and press a switch or foot-pedal.

~

hmm! This physical work should and can be automated. What about
emulating this with software either directly through the camera's USB
port or with an extra mechanical device strapped to the digital
camera? Then all you would set is the timing of when the switch goes
off
~
Also it would be better if the user has free(r) hands to operate a
computer with a GUI on which the scanned pages are being shown, etc

Re: scanning + OCR the monkey way ... 99gphoto

I am working on such a project for the MacIntosh.
My plan is to build a platform with uniform lighting where I place the
book on the platform , press it flat with glass and press a switch or
foot-pedal.
The pages are captured as an image, the image appears to be visually
proofed. Meanwhile the glass is lifted and the page is flipped.
Then repeat.
The images are captured in a file. Then they can be transferred
anywhere for OCR.

I have a Canon Powershot A80 successfully taking pictures using Icarus
Camera Control. I am talking to the author about adding more
automation features. The same thing can be done via gPhoto. I am now
working on improving the lighting control. I am an electronics
engineer so this is within my capability. I will be glad to help you
as you explore options.

Pictures clock

2009-11-27T02:03:33Z

Hi,

Is that possible to catch the events “GP_EVENT_FILE_ADDED” (gp_camera_wait_for_event) in one thread and download the pictures

(gp_camera_file_get) in another thread?

The aim is to get immediately, at the return of the function gp_camera_wait_for_event, the system clock in order to date exactly

the pictures even if the user perform a burst. In my case, I have other devices connected to the computer and their data are also dated

with the system clock. The pictures and all the data must be time synchronized.

Best regards,

Re: Canon 1000D capabilities missing

2009-11-26T03:32:58Z

Thanks for the quick reply Marcus. I've tried your latest version and I indeed see the ability to change the picturestyle (dial mode) and manualfocus. Are either of these implemented?

I also noticed that in this version the camera does not have to be in P or M mode to start liveview. Was this feature added? Unfortunately even in this version when I issue the --capture-preview command in gphoto2 I get 1 frame and then get a Segmentation fault (Ubuntu 9.10). Any suggestions?

Great work.

Yes, this is done with the "picturestyle" configuration variable.

I have started to implement this in 2.4.7.3+

but I so far did not finish it.

2009-11-25T23:19:04Z

As we can identify the error and knowledge because it is happening?
This error is known for other people with 'Canon EOS 500D'?

2009/11/25 Alberto <sepu66@...>

Thank U Marcus! But it not work :(
If I set 'capturetarge=1' and later I execute ' gphoto2 --capture-image' the camera remains blocked, after minutes, appears an error on console:
ERROR: Could not capture.
*** Error (-1: «Error no especificado») ***

With ' --debug' activated the next message appears few times:

Set the capturetarget to "card".

"lock mirror up" ?

Bulb Mode?

You need something like this for EOS Bulb Mode:
gphoto2 --set-config bulb=1 --wait-event=10s --set-config bulb=0 --wait-event-and-download=2s

No. We have a reimplementation of its functionality.

But we support the same cameras that the SDK supports.

For non-DSLR I recommend the Canon PowerShot series (the ones that are
able to capture).

For DSLR I recommend Nikon DSLRs.

Canon 1000D capabilities missing

2009-11-25T11:09:36Z

Hi,

I am unable to switch dial modes with libgphoto2. I have done this with the Canon SDK with the following command:

PropID_AEMode = 0x00000400;

Standard = 0x0081;
Portrait = 0x0082;
Landscape = 0x0083;
Neutral = 0x0084;
Faithful = 0x0085;
Monochrome = 0x0086;
User1 = 0x0021;
User2 = 0x0022;
User3 = 0x0023;
PC1 = 0x0041;
PC2 = 0x0042;
PC3 = 0x0043;

EdsSetPropertyData(this.CameraDevice, PropID_AEMode, 0, 4, AEMode_Portrait);

Can this be done with libgphoto2?

Also, the focus can be set in LiveView with the following Canon SDK command:

CameraCommand_DriveLensEvf = 0x00000103;
EdsSendCommand(this.CameraDevice, CameraCommand_DriveLensEvf, (int)EDSDK.EdsEvfDr.EvfDriveLens_Far3);

This also seems to be missing. Any help would be appreciated!

Canon 1000D remote capture capability

2009-11-25T10:54:14Z

Hello, Are there anyone out there tried the canon 1000D's remote
capture capability ?
It says on the remote page that it has limited configuration.

Anyone know what is the extend of the limited configuration ?

Another question would be am I able to use the viewfinder and execute
remote capture at the same time ?

On the curious side for 1000D user, how fast in terms of FPS is the
remote capture capability ?

Thank you ~!

Specifically I am interested in mirror lockup. If I turn mirror lockup on on my camera, when I initiate "Capture-image" in gphoto2, the mirror locks up, but no picture is taken. The fact that no image data is generated or stored seems to screw up gphoto2 so I can't just do "capture-image" twice in order to lock up the mirror and then take a photograph.

i would also be interested to know the different methods I can use to vary the exposure time (bulb shutter).

Thanks,
Robert

remove the "PTPBUG_DELETE_SENDS_EVENT|" part?

It seems the camera does not send events and this might confuse the protocol stack :/

I've edited the library.c file, and saved an old copy. I've then run:

./configure --prefix=/usr
make clean
make
make install

Next, I ran the following commands in debug mode, and have included the logs (removed picture data)

(1) gphoto2 --auto-detect auto-detect.txt
(2) gphoto2 --summary summary.txt
(3) gphoto2 --capture-preview capture-preview.txt capture-preview2.txt capture-preview3.txt
(4) gphoto2 --capture-image capture-image.txt capture-image2.txt
(5) gphoto2 --capture-image-and-download capture-image-and-download.txt capture-image-and-download2.txt

When I ran (2), the LCD readout on the camera changed from "Pb" to "PC", and the light went from green to orange. Then I ran (3), and it failed. I then power-cycled the camera, and ran (3) again, and again, both failed, and the logs from each run are attached. I then power-cycled the camera, and ran (4) twice, both successfully. I then ran (5) twice, and the first was successful, and the second failed, and the process had to be killed.

Hope this is useful.

The operations are a mix between official PTP comands (the 0x10.. ones)
and Canon Vendor codes (the 0x9... ones).

Lots of the Canon Vendor codes have been reverse engineered and are
implemented in libgphoto2. The defines are in camlib/ptp2/ptp.h,
PTP_OC_CANON_EOS_xxxx

What specifcally do you want to know?

Thank U Marcus! But it not work :(
If I set 'capturetarge=1' and later I execute ' gphoto2 --capture-image' the camera remains blocked, after minutes, appears an error on console:
ERROR: Could not capture.
*** Error (-1: «Error no especificado») ***

With ' --debug' activated the next message appears few times:

Summary: The file is of an unknown type

Initial Comment:
I plug in my Creative ZEN, Ubuntu automounts it with gphoto2, I unmount it since that's the only useful thing it can do. I run "sudo gphotofs /media/mp3" and my ZEN get's mounted. I try to view the contents of the ZEN using Nautilus and it says "The file is of an unknown type". I can view the contents as root by running "nautilus /media/mp3/store_00010001/" but I get an Access Denied error when I try that as non-root.

Message:
I tried Banshee, it crashed while I was importing my library, then it
crashed when I was starting it up after it crashed, and it thinks I have
only one song on my MP3 player as opposed to 164 songs. Amarok can't even
sort my music properly. I wonder if aTunes works.

Message:
I suggest to unmount it and start banshee or rhythmbox or amarok, which can
handle MTP devices pretty well these days.

And "nautilus /media/mp3/store_00010001/" would be basically the same as
if Nautilus automounts gphoto2.

Canon EOS 500D

2009-11-25T06:47:23Z

Hi!
I have compiled and installed these versions:
libgphoto2-2.4.7
gphoto2-2.4.7
gphotofs-0.4.0
on Ubuntu Linux 9.10 Karmic Koala with kernel 2.6.31-15.
All the functions of Gphoto2 work correctly with my Canon EOS 500D. The problem is when use the option '--capture-image', the camera realises the photography, but the image is not written in the camera and either in the PC. If use '--capture-image-and-donwload' it works and the image is stored in the PC, but I need that the image is stored in the camera.

Best regards!!!

Re: Problems building libgphoto2 2.4.7 on mac

2009-11-25T05:19:18Z

I managed to get a bit further in the compilation by configuring with

./configure CFLAGS=" -I${prefix}/include -no-cpp-precomp" \
--mandir=${prefix}/share/man --with-drivers=all --with-libexif=auto

(I looked at what macports was doing to compile 2.4.4). However, the compilation still crashes, but with the following error:

libtool: link: gcc -o .libs/ptp2.so -bundle ptp2/.libs/ptp.o ptp2/.libs/library.o ptp2/.libs/usb.o ptp2/.libs/ptpip.o ptp2/.libs/config.o ../libgphoto2/.libs/libgphoto2.dylib -L/opt/local/lib /Users/tom/install/libgphoto2-2.4.7/libgphoto2_port/libgphoto2_port/.libs/libgphoto2_port.dylib -lltdl /opt/local/lib/libltdl.dylib /opt/local/lib/libexif.dylib /opt/local/lib/libintl.dylib -lc -lm /opt/local/lib/libiconv.dylib -Wl,-dylib_file -Wl,/usr/local/lib/libgphoto2_port.0.dylib:/Users/tom/install/libgphoto2-2.4.7/libgphoto2_port/libgphoto2_port/.libs/libgphoto2_port.dylib -Wl,-exported_symbols_list,.libs/ptp2-symbols.expsym

make[3]: *** [ptp2.la] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

This is both for 2.4.7 and the most recent svn version. It looks like the CFLAGS passed to configure aren't making it to this specific compile command (I see -I/include -no-cpp-precomp in all other commands but not this one).

Thanks for any help,

Thomas
