<!-- Array of light sensor LUX values to define our levels for auto backlight brightness support.
|
||||
The N entries of this array define N + 1 control points as follows:
|
||||
(1-based arrays)
|
||||
Point 1: (0, value[1]): lux <= 0
|
||||
Point 2: (level[1], value[2]): 0 < lux <= level[1]
|
||||
Point 3: (level[2], value[3]): level[2] < lux <= level[3]
|
||||
The N entries of this array define N 1 zones as follows:
|
||||
Zone 0: 0 <= LUX < array[0]
|
||||
Zone 1: array[0] <= LUX < array[1]
|
||||
...
|
||||
Point N+1: (level[N], value[N+1]): level[N] < lux
|
||||
The control points must be strictly increasing. Each control point
|
||||
corresponds to an entry in the brightness backlight values arrays.
|
||||
For example, if LUX == level[1] (first element of the levels array)
|
||||
then the brightness will be determined by value[2] (second element
|
||||
of the brightness values array).
|
||||
Spline interpolation is used to determine the auto-brightness
|
||||
backlight values for LUX levels between these control points.
|
||||
Zone N: array[N - 1] <= LUX < array[N]
|
||||
Zone N + 1 array[N] <= LUX < infinity
|
||||
Must be overridden in platform specific overlays -->
