Parameters Description
Brightness
Change the overall brightness of the picture. The higher the
value is, the brighter the picture will be, and the smaller the
darker. The picture might be hazy if the value is configured too
high.
Contrast
Changes the contrast of the picture. The higher the value is, the
more the contrast will be between bright and dark areas, and
the smaller the less. If the value is set too high, the dark area
would be too dark and the bright area easier to get
overexposed. The picture might be gray if the value is set too
small.
Saturation
Makes the color deeper or lighter. The higher the value is, the
deeper the color will be, and the lower the lighter. This value
does not affect the overall brightness of image.
Gamma
Changes the picture brightness and contrast in a non-linear
way. The higher the value is, the brighter the picture will be,
and the smaller the darker.
