6 Description of the scale of the brightness curve.
8 The human eye senses brightness approximately logarithmically,
9 hence linear changes in brightness are perceived as being
10 non-linear. To achieve a linear perception of brightness changes
12 backlights with a linear brightness curve.
17 The scale of the brightness curve is unknown.
20 The brightness changes linearly with each step. Brightness
24 non-linear
25 The brightness changes non-linearly with each step. Brightness
