In a method of determining an exposure amount, image data is fetched, and an image is divided into a plurality of regions by binarization or another technique, a shape pattern representing a contour of the head of a human figure is detected, and a face candidate region is set in accordance with the detected pattern. Next, a shape pattern representing a contour of the face of the human figure, a shape pattern representing an internal structure of the face of the human figure, and a shape pattern representing a contour of the body of the human figure are detected respectively. The consistency of a face candidate region is determined consecutively by the detected patterns, and a region having the highest probability of being a region corresponding to the face of the human figure is determined. The above processing is carried out a plurality of times while a threshold for binarization and parameters for controlling the relative fineness of the division of the image are varied. The data on the finally determined facial region is outputted as a result of determination.

A method of determining an exposure amount, comprising the steps of: searching a first shape pattern which is present in an original image and is peculiar to a first portion of a human figure; setting a region estimated to correspond to a face of the human figure, in accordance with a size and a direction of the searched first shape pattern and a positional relationship between the face of the human figure and the first portion; determining a region having a high probability of being a region corresponding to the face of the human figure in the original image, by searching whether or not a second shape pattern peculiar to at least one second portion different from the first portion of the human figure is present in a range of search set in accordance with the set size and direction of the first shape pattern in the original image and a positional relationship between the face of the human figure and the second portion; and determining an exposure amount for printing the original image onto a printing material on the basis of at least one of a color and a density of the determined region.
