A very straightforward software written in C++ is v4l2ucp (Video for Linux Two ucp). It uses Qt libraries on Linux to read a description of the controls that the V4L2 device supports from the device, and presents the user with a graphical means for adjusting those controls.

In a one-page interface you will be able to control as much as (controls will depend on your device):

brightness

contrast

saturation

hue

white balance temperature

gamma

power line frequency

sharpness

backlight compensation

exposure auto mode

This can be extremely useful in dark room for example.
