Abstract
Provided are a real-time face recognition-based selective recording apparatus and method. The apparatus includes a face recognition unit which recognizes a face of a person in a decompressed input image frame; a recording position setting unit which sets one of an image frame in which the person appears and a scene change start frame including the image frame as a valid recording point if the recognized face is detected for a predetermined period of time or detected a predetermined number of times, and identifies a position, which corresponds to a set image frame, in an image compression stream; and a recording unit which records the image compression stream from the identified position and storing the recorded image compression stream in real time.
