Brightness
Brightness is the overall lightness of the image. Move the slider left or right to darken or lighten the image.
Adjusting the brightness level adjusts the tone of the pixels, without changing the true color of the pixels; such as
when adjusting hue.
Note: This option is disabled when Threshold is selected while scanning in black and white.
