Logitech QuickCam Pro 9000

This document contains various experiences with the Logitech QuickCam Pro 9000 webcams. Feel free to add any experiences you might have.

The cameras are cheap decent quality webcams. At the moment these costs about 500 DKr. They have a very wide angle lens, and produce quite good images (they actually have a decent lens unlike other webcams). However, they also seem to produce more motion blur than I like. If you want to use these cameras, get in contact with Soren Hauberg.

Linux

The cameras should work out-of-the-box on any recent Linux distribution. It uses the 'uvc' driver, which is part of recent kernels. You can test it with programs such as 'Cheese' or directly in OpenCV.

You can set some attributes of the camera directly from the command line. To see which attributes the driver supports, type 'v4lctl -c /dev/video0 list'. On my box I get

 attribute  | type   | current | default | comment
 -----------+--------+---------+---------+-------------------------------------
 norm       | choice | (null)  | (null)  |
 input      | choice | Camera  | Camera  | Camera 1
 bright     | int    |     128 |     128 | range is 0 => 255
 contrast   | int    |      32 |      32 | range is 0 => 255
 color      | int    |      32 |      32 | range is 0 => 255
 White Bala | bool   | on      | on      |
 Gain       | int    |       1 |       0 | range is 0 => 255
 Power Line | choice | 60 Hz   | 60 Hz   | Disabled 50 Hz 60 Hz
 White Bala | int    |       0 |    4000 | range is 0 => 10000
 Sharpness  | int    |     224 |     224 | range is 0 => 255
 Backlight  | int    |       1 |       1 | range is 0 => 2

You can then set the attributes by running e.g. "sudo v4lctl -c /dev/video0 setattr 'gain' 1".

I'm experiencing quite a bit of motion blur. I haven't figured out what to do to avoid this. Usually you would just lower the shutter speed, but I can't figure out how to do that.
