[Linux-uvc-devel] Quickcam Pro 5000 - Pinkish images

[Nicolas M. <ni...@mi...>]

Hello,

I successfully compiled and installed the uvcvideo driver on a Linux
2.6.12-1.1381_FC3 running on a VIA EDEN 5000 motherboard (USB 1.1).

My Quickcam Pro 5000 is correctly detected

and I can take pictures with the test program (test.c) posted on this list
some time ago. I then convert the pictures (adding the missing the Huffman
tables) with the Python script available in the svn trunk.

So far, so good, indoor pictures looks fine, but outdoor pictures looks
pinkish (e.g. http://sirius.mizel.net/quickcam-099.jpg).

What could be causing this problem? Something wrong with the Huffman tables?
I'll test tonight my camera with the Logitech software just in case.

Also, how do I set up the camera parameters such as Brightness, Contrast,
Saturation, Backlight Compensation, etc. Maybe that's what I am missing...

Thanks for all the hard work spent on this cool driver.

Best regards,
Nicolas
