Patent ID: 8384791

Claim:
A video camera arrangement comprising: an image capture device having an associated lens with an adjustable focus and a zoom setting; a face detector for detecting human faces in images captured by the image capture device and for generating face data identifying detected occurrences of faces in the captured images, the face detector (1) configured to detect faces at a plurality of different image scales by resealing the captured images over the image scales, and (2) receiving a lens focus and a zoom setting from the image capture device to (a) determine a distance of a face from the video camera to calculate an expected face size, and (b) calculate a subset of the image scales for face detection within the captured images based on the expected face size; a data handling medium by which data representing the captured images is transmitted and/or stored, the data handling medium comprising a storage medium for storing the captured images and a metadata store for storing metadata associated with the captured images, the metadata including the face data generated by the face detector, the lens focus and the zoom setting; and a processor for generating data to be transmitted or stored by the data handling medium in dependence on the detection of faces in the captured images.
