ABSTRACT:
An auxiliary light source such as a flash is controlled for highly accurately reflecting a lighting condition with less effect of a factor other than the lighting condition such as contrasting density caused by shadow or black compression or white compression. For this purpose, a parameter acquisition unit obtains weighting parameters for principal components representing lighting conditions in a face region in an image detected by a face detection unit, by fitting to the detected face region a mathematical model generated according to a method of AAM using a plurality of sample images representing human faces in different lighting conditions. A flash control unit obtains a flash control condition by referring to a reference table according to the parameters, and controls flash light emission according to the control condition.
