In some examples, the target luma average may be provided. In such examples, the target luma average may be provided and used until a new target luma average is provided. In other examples, a plurality of target luma averages may be provided for different situations. For example, the target luma average may be slightly higher outside than indoors because it may be brighter outdoors. Accordingly, in some examples, two different target luma averages may be provided or determined: one for indoor and one for outdoor. In other examples, the target luma average may be determined. In such examples, a current physical environment may be determined based upon one or more sensors. For example, the one or more sensors may detect an amount of light in the current physical environment. In some examples, any combination of the one or more settings may be used to determine the target luma value.
