ABSTRACT:
A method of determining an amount of exposure in a process of reproducing a face density, which is extracted from an original image of a photographed human subject, at a target density. When there are a plurality of people among photographed subjects and face densities differ greatly, the face densities are divided into two groups of higher and lower face densities. Thereafter, the face density of a group which is determined to be a standard density is finished as an appropriate density. Further, in a process of effecting reproduction at the target density, density correction of a face is not effected in a case in which a face density of a photographed subject is extremely high.
