My laptop has a camera. But I don't know how to use it, how to mount it. I want to know the name of camera under /dev. Such as a harddisk is sda or hd. Please help. Thank you guys

Can you get us the output from the lspci and lsusb commands.

It is probably a webcam not a camera and is impossible to mount AFAIK. You can however record from it and view it and use it for VOIP if you have the right drivers installed.

You can't mount a webcam as you'll get the following message:
I have a Logitech Quickcam Pro 9000 which works with the UVC driver, and I use luvcview to take pictures with it.

The OP said he had a laptop with a camera. So I assumed he ment a build-in camera. Most of these are connected through an internal USB port. That's why I asked for the lsusb output. But unless the OP is a little more specific about the camera we probably need to pull out our crystal balls to get to the right answer.

lsusb would be very useful, because it usually is on the USB bus.

My bad. I think maybe it's a webcam.

It's like what gdejonge said. A built-in cam.


And thanks guys.

The camera is listed here as working, so you need the uvc drivers.
http://www.ideasonboard.org/uvc/#status

Check 'lsmod' to see if the module is already working.

If it is working, then the camera will be seen by whatever programs you use with it.

lsmod | grep uvc
uvcvideo 71338 0
videobuf2_vmalloc 12839 1 uvcvideo
videobuf2_core 31355 1 uvcvideo
videodev 92409 2 uvcvideo,videobuf2_core
media 19719 2 uvcvideo,videodev

The camera should be working just fine, what programs have you tried? Skype? Cheese?

I just want to know its name under /dev. Thanks everyone. I've learned many new. I didn't know cheese before. I'll have a try.

It may be listed as /dev/video0.
