Identification apparatus and identification method

Abstract

An identification apparatus including an image capturing device, at least one light emitting device disposed beside the image capturing device and a zoom lens disposed above the image capturing device is provided. The light emitting device is adapted to emit a visible light and an invisible light. A focal length of the zoom lens is adapted to be switched to a first focal length or a second focal length. The light emitting device emits the visible light and the focal length of the zoom lens is switched to the first focal length so that the image capturing device captures a fingerprint image of a finger. The light emitting device emits the invisible light and the focal length of the zoom lens is switched to the second focal length so that the image capturing device captures a vein image of the finger. Moreover, an identification method is also provided.

What is claimed is: 
     
         1 . An identification apparatus, comprising:
 an image capturing device;   at least one light-emitting device disposed beside the image capturing device, and adapted to emit a visible light and an invisible light; and   a zoom lens, disposed above the image capturing device, wherein a focal length of the zoom lens is adapted to be switched to a first focal length or a second focal length,   the at least one light-emitting device emits the visible light and the focal length of the zoom lens is switched to the first focal length so that the image capturing device captures a fingerprint image of a finger,   the at least one light-emitting device emits the invisible light and the focal length of the zoom lens is switched to the second focal length so that the image capturing device captures a vein image of the finger.   
     
     
         2 . The identification apparatus as claimed in  claim 1 , further comprising:
 a processing unit, electrically connected to the image capturing device, and verifying the fingerprint image, the vein image or a combination thereof, and determining true or false of the finger according to a verifying result of the fingerprint image, a verifying result of the vein image or a combination thereof.   
     
     
         3 . The identification apparatus as claimed in  claim 1 , wherein the at least one light-emitting device comprises:
 a first light-emitting device, adapted to emit the visible light; and   a second light-emitting device, adapted to emit the invisible light.   
     
     
         4 . The identification apparatus as claimed in  claim 1 , further comprising:
 a circuit board, the image capturing device being disposed on the circuit board and electrically connected to the circuit board.   
     
     
         5 . The identification apparatus as claimed in  claim 1 , further comprising:
 a main body, the image capturing device, the at least one light-emitting device and the zoom lens being disposed in the main body.   
     
     
         6 . The identification apparatus as claimed in  claim 5 , further comprising:
 a transparent pressing plate, disposed on the main body and shielding the light capturing device, the at least one light-emitting device and the zoom lens.   
     
     
         7 . An identification method, comprising:
 providing an identification apparatus, wherein the identification apparatus comprises an image capturing device, at least one light-emitting device disposed beside the image capturing device and a zoom lens disposed above the image capturing device, wherein the at least one light-emitting device is adapted to emit a visible light and an invisible light, and a focal length of the zoom lens is adapted to be switched to a first focal length or a second focal length;   making the at least one light-emitting device to emit the visible light to irradiate a finger, and switching the focal length of the zoom lens to the first focal length so that the image capturing device captures a fingerprint image of the finger;   making the at least one light-emitting device to emit the invisible light to irradiate the finger, and switching the focal length of the zoom lens to the second focal length so that the image capturing device captures a vein image of the finger; and   verifying the fingerprint image, the vein image or a combination thereof, and determining true or false of the finger according to a verifying result of the fingerprint image, a verifying result of the vein image or a combination thereof.   
     
     
         8 . The identification method as claimed in  claim 7 , wherein if the finger is determined to be true, the identification method further comprises:
 determining an identification of a user having the finger according to the fingerprint image, the vein image or the combination thereof.   
     
     
         9 . The identification method as claimed in  claim 7 , wherein the finger is determined to be true when the fingerprint image is verified to be true and the vein image is verified to be true. 
     
     
         10 . The identification method as claimed in  claim 7 , wherein after the fingerprint image is captured and verified, the vein image is captured and verified. 
     
     
         11 . The identification method as claimed in  claim 10 , wherein true or false of the finger is determined according to the verifying result of the vein image other than according to the verifying result of the fingerprint image. 
     
     
         12 . The identification method as claimed in  claim 7 , wherein after the vein image is captured and verified, the fingerprint image is captured and verified. 
     
     
         13 . The identification method as claimed in  claim 12 , wherein true or false of the finger is determined according to the verifying result of the fingerprint image other than according to the verifying result of the vein image.
