摘要

An apparatus for recognizing a face of a person adaptively controls brightness of illumination around the person through image analysis. The apparatus obtains an optimal image through the adaptive brightness control of the illumination regardless of various environments for face recognition.

主权项

1. An apparatus for recognizing a face of a person, comprising:
a first acquirer configured to acquire a visible light image of the person; a second acquirer configured to acquire an infrared image of the person; an analyzer configured to detect respective face areas from the visible light image and the infrared image, estimate a face area of the visible light image by using the infrared image in the case of not detecting the face area of the visible light image, and analyze facial features in the detected or the estimated face area of the visible light image to determine suitability of face recognition; and a controller configured to control, when the analyzer determines that the face area of the visible light image is not suitable for face recognition, brightness of illumination so that the first acquirer re-acquires a visible light image from which a face is recognizable.
