1. An image processing apparatus comprising: first evaluation value calculation means for extracting a feature quantity of a first feature from the entirety of an input image, and for calculating a first partial evaluation value indicating an evaluation for the input image based on the first feature on the basis of the feature quantity of the first feature; second evaluation value calculation means for extracting a feature quantity of a second feature from a predetermined area of the input image, and for calculating a second partial evaluation value indicating an evaluation for the input image based on the second feature on the basis of the feature quantity of the second feature; and overall evaluation value calculation means for calculating an overall evaluation value indicating an evaluation of an image-capture state of the input image on the basis of the first partial evaluation value and the second partial evaluation value.
