MSI StarCam Clip Webcam - problem activating IR LEDs


hello

i have a MSI Starcam Clip, and i am developping an application to use it as a motion tracking system.

I am using the OpenCV libraries.

I can get the image very well, but the problem is that this camera has 3 Infrared LEDs that automaticly turn on, when the light is low. At least this is what happens in Windows, but it's not happening over Linux.

I thought that it had something to do with a internal control of the camera, so it should be independent of the system it's installed on, but apparently no.

now, I don't know what to do... maybe i could send some bytes to the camera, to activate them? there must be some way of doing this...

any ideas?

thanks

Alexandre

Re: MSI StarCam Clip Webcam

Hello....

Is your MSI StarCam Clip Webcam
giving ("lsusb") ID 0c45:60c0 Microdia

(according to
http://www.qbik.ch/usb/devices/showdev.php?id=3951
it is with ID: 0x0c45:0x60c0)

as the:

MSI Starcam 370i
http://www.msi.com.tw/program/produc...il.php?UID=604

Hello...again...

I am unable to help you on how to get
the IR LEDs on and off, but...

IF "lsusb" reports: ID 0c45:60c0 Microdia
I would really like to know:

How did you get any images out of this webcam
on Linux.... ?


I am on Ubuntu 6.10 (Edgy) and tried
the modules, spca5xx, gspcav1, ...

and did not get any good pictures
except a dotted matrix, with a little
colored horizontal bar on the top...
http://www.wgz.ca/camorama-snapshot.png

I have already mentioned my attempts on getting
some images out of that camera on sites:
http://ubuntuforums.org/showthread.php?t=320433
http://forum.ubuntu-fr.org/viewtopic.php?id=80143
and noticed other sites mentioning the problem:
http://www.linux-projects.org/module...id=248&forum=3
http://www.abclinuxu.cz/hardware/vst...i-starcam-370i

Could you specify if MSI STARCAM CLIP WEBCAM
is the "same" (lsusb ID report when the camera is hooked)
as the "MSI STARCAM" I am referring ?

Is the linux distribution/version you
are using when you get pictures from your MSI Starcam Clip webcam...
the same as the one mentioned under your nickname (KUbuntu 6.06) ?

And, could you tell us what module (spca5xx, gspcav1, or...) and version
you loaded to get the camera's images....?

Do you get the images from direct calls using "openCV" library you mentionned:
http://opencvlibrary.sourceforge.net/
or can you get images displayed under
video 4 linux (v4l) using tools like camorama:
http://camorama.fixedgear.org/shots.php

Thanks....


Nicolas

hey

sorry for only answering now...
i am kind of in a hurry, so maybe i am not answering to all your questions... i'll check this post later, as soon as i have time...
meanwhile i can tell the following:

details of my camera:

product id: 0x60c0
vendor id: 0xc45

check this url to see the compatibilty charts: http://mxhaard.free.fr/spca5xx.html
my webcam is detected as a sangha webcam.

i am using spca5xx

my distr is: kubuntu 6.06

i only tried to get the images directly trhu opencv, but opencv uses V4L, and i know it loads the spca5xx module.
