How to use adjust webcam parameters?
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.
