Detailed Description

The boundaries and target for an AeConstraintMode constraint.

This structure describes an AeConstraintMode constraint for the purposes of this algorithm. These constraints are expressed as a pair of quantile boundaries for a histogram, along with a luminance target and a bounds-type. The algorithm uses the constraints by ensuring that the defined portion of a luminance histogram (I.E. lying between the two quantiles) is above or below the given luminance value.
