In a pattern recognition apparatus, a characteristic amount calculation unit calculates a characteristic amount for recognizing a desired object from a partial image clipped from an input pattern, a likelihood calculation unit calculates a likelihood of an object as a recognition target from the characteristic amount calculated by the characteristic amount calculation unit by referring to an object dictionary, and an object determination unit determines whether the partial image is the object as the recognition target based on the likelihood of the object calculated by the likelihood calculation unit. The likelihood calculation unit calculates the likelihood of the object as the recognition target from the characteristic amount calculated by the characteristic amount calculation unit by referring to a specific object dictionary. The object determination unit determines whether the partial image is a specific object as the recognition target from the likelihood of the object calculated by the likelihood calculation unit.
