Some usefull setting for the module you can also use sysfs kernel 2.6.x like this:
echo "4" > /sys/module/spca5xx/gamma
echo "217" > /sys/module/spca5xx/GRed
should set the gamma parameters to 4 and GRed to 217
The Gimp is usefull to get the good value :)

Logitech QuickCam express id 0x0920  or Labtech 0x0921
modprobe spca5xx GRed=217 GBlue=300 GGreen=224 gamma=4 
Creative Vista 0x403b maybe the same for Logitech QC express etch2 0x0928
modprobe spca5xx OffRed=16 OffGreen=-32 OffBlue=-16 GBlue=288 GGreen=288
