asettaa manuaali tarkennuksen päälle
asenna ensin:
sudo apt-get install v4l-utils

Jos koneessa on useampi kuin yksi web camera, täytyy ajuri käsky kohdistaa oikeaan ajuriin.
Yleensä lappärissä on oma kamera se on /dev/video0
Toinen on siis USB lisätty kamera eli /dev/video1
Jos koneessa ei ole kuin yksi kamera kohdistus käskyä /dev/video0 ei tarvitse käyttää, mutta ei haittaakaan ole.
v4l2-ctl -d /dev/video0 --set-ctrl focus_auto=0
v4l2-ctl -d /dev/video1 --set-ctrl focus_auto=0

Kolmas kamera olisi v4l2-ctl -d /dev/video2 --set-ctrl focus_auto=0

Tämän hetken asetukset tulee näytölle: v4l2-ctl -d /dev/video0 --list-ctrls
v4l2-ctl --set-ctrl focus_auto=0

manuaali tarkennus
v4l2-ctl --set-ctrl focus_absolute=35

tarkennus
v4l2-ctl --set-ctrl sharpness=220

värit
v4l2-ctl --set-ctrl saturation=160

v4l2-ctl --set-ctrl gain=161

asettaa 50 hz
v4l2-ctl --set-ctrl power_line_frequency=1

kirkkaus
v4l2-ctl --set-ctrl brightness=117


v4l2-ctl --set-ctrl pan_absolute=0
