Abstract:
1. A digital camera for capturing an image of a scene, said digital camera comprising: a capture section for capturing an image and producing image data; an electronic processing section for processing the image data to determine the presence of one or more faces in the image; face data means associated with the processing section for generating face data corresponding to at least one attribute of at least one of the faces in the image; a storage medium for storing the image data; and recording means associated with the processing section for recording the face data with the image data on the storage medium; wherein the electronic processing section utilizes a face detection algorithm having a first component and a second component; the first component comprising a pre-screening pattern recognizer that searches for image windows likely to contain faces, the first component having a first rate of false positives and determining a plurality of face candidates; the second component comprising a posterior probability function classifier, the second component having a second rate of false positives lower than the first rate of false positives, and processing the plurality of face candidates to determine the presence of the one or more faces in the image.
