Abstract:
1. A photographing apparatus comprising: a photographing unit for obtaining an image representing a subject through photographing; a face detecting unit for detecting a face from the image obtained by the photographing unit; and a reflectance calculating unit for calculating a reflectance of the face, the reflectance calculating unit obtaining a result of the face detection by the face detecting unit at a predetermined point of time after acquisition of the image by the photographing unit has begun, obtaining images of the same subject taken with flash emission and taken without flash emission, and if the obtained detection result indicates that a face is contained, calculating the reflectance of the face based on a difference in brightness of the face between the images taken with flash emission and taken without flash emission and the size of the face; wherein the reflectance calculating unit calculating a reflectance of the face contained in the area to be photographed according to the equation: wherein Rf is the reflectance of the face, R0 is a reference reflectance at a reference distance, Lrf is an amount of reflected light from a face, S0 represents a size of a face region of a face having a reference reflectance R0, Lr0 represents an amount of reflected light at a reference reflectance R0, and Sf is a size of a face region.
