| Summary: | In the AF processing section, the parameter obtaining section obtains a weighting parameter value for a principal component that represents a sharpness level of a face portion of an image, an example of a predetermined structure in an image, detected by the face detection section by applying the detected face portion to a model generated by a predetermined statistical processing, such as AAM or the like, based on a plurality of images that represent the face portion in different sharpness levels, and the control amount determination section determines the focus control amount according to the obtained parameter value. |
