1. An image processing apparatus comprising:
- resolution conversion means for converting at least a predetermined structure in an input image to have a desired resolution;
a model representing the predetermined structure by a characteristic quantity obtained by carrying out predetermined statistical processing on a plurality of images representing the structure in the same resolution as the desired resolution; and
reconstruction means for reconstructing an image representing the structure after fitting the model to the structure in the input image the resolution of which has been converted.

Abstract
Resolution of an input image is converted more easily by using a method of AAM. For this purpose, a resolution conversion unit converts resolution of the image having been subjected to correction, and a face detection unit detects a face region in the resolution-converted image. A reconstruction unit fits to the face region detected by the face detection unit a mathematical model generated through the method of AAM using a plurality of sample images representing human faces having the same resolution as the image, and reconstructs an image representing the face region after the fitting. In this manner, an image whose resolution has been converted is obtained.
