Patent ID: 7155037

Claim:
A face recognition apparatus comprising: a face recognizer; an image input section for receiving image data; a face direction detector for detecting whether a face is within the image data received and for detecting a direction of the face, when the face is detected, through separation of a first brightness and chromaticity of the received image data and comparison of the first brightness and chromaticity with a preset second brightness and chromaticity; a driver for changing at least one of a position and an angle of the image input section such that the face direction detector calculates the direction of the face, when the face is detected, from a plurality of received image data based on a peak value of a ratio of an area of a specified color of the face to an area of a head in the image data; and a movement controller for controlling the driver based on whether the face is detected and based on the direction of the face when the face is detected, until a face is detected, wherein the movement controller directs the driver to move the image input section so that the ratio of the area of the specified color of the face to the area of the head in the image data increases.
