1. A person detection apparatus comprising:
- a motion region detection unit, which detects a motion region from a current frame image using motion information between frames; and
a person detecting/tracking unit, which detects a person in the motion region by using shape information of persons, and performs a tracking process, on the person in a previous frame image, within a predetermined tracking region.

33. A privacy protection system comprising:
-
a motion region detection unit, which detects a motion region from a current frame image using motion information between frames;
a person detecting/tracking unit, which detects a person in the motion region using shape information of persons, and performs a tracking process on the motion region detected as the person in a previous frame image within a predetermined tracking region;
a mosaicking unit, which detects a face in the motion region which is determined to correspond to the person, performs a mosaicking process on the face, generates a mosaicked face and displays the mosaicked face; and
a storage unit, which stores the motion region which is detected or tracked as the person, and stores predetermined labels and position information used for searching frame units. - View Dependent Claims (34)
