Public Attributes
float	luminance_min
	Minimum boundary for computed luminance.
float	luminance_max
	Maximum boundary for computed luminance.
float	exposure_correction
	Luminance bias. Higher values make the scene darker, can be negative.
float	speed_dark_bright
	Speed of transition from dark to bright scenes.
float	speed_bright_dark
	Speed of transition from bright to dark scenes.
float	center_weight_power
	Power value for center-weighted metering. Value of 1.0 measures entire screen uniformly.

Detailed Description

Parameters for automatic exposure compensation.

Automatic exposure compensation uses the following equation:

wanted_exposure = 2^exposure_correction / clamp(observed_luminance, 2^luminance_min, 2^luminance_max)
