The present invention relates to a face recognition apparatus based on even light source, which includes a data processor (1), an imaging device (2) used to capture a face image and transport the face image to said data processor (1) for image processing, and an optical device (3) used to form an image of human face onto said imaging device (2). The optical device (3) further includes a camera lens (4) and an even light source device (5) located near or surrounding said camera lens (4). The even light source device (5) includes a light emitter (6) and an even light source generation device (7) which is used to generate indirect even light source by means of refraction, diffraction or reflection of light emitted by said light emitter (6). Light radiated onto the human face is evener due to the even light source, thus a better image effect is achieved to facilitate improving recognition quality and processing speed. Further, the apparatus may not bring irritation to human eyes, and may enhance comfortability during the recognition process. |
