実施の形態1.
図1は、この発明の実施の形態1に係る個人識別装置の構成を示すブロック図である。図1に示される個人識別装置は、指紋を有する被検体である指1の爪側に対し照射角度が異なる透過光を照射するための複数の光源31〜33を有する光源3と、指1の指紋表面を非接触状態で支持する指支持部2A,2Bと、指支持部2A,2Bに支持された指1の指紋を透過する照射角度の異なる複数の光源31〜33からの光を撮像して指紋に対応する複数の指紋画像を得る撮像部4と、前記撮像部4からの複数の指紋画像を画像処理してコントラストが最も良い指紋画像を選択して個人識別する信号処理部5とを備えており、前記光源31〜33の光軸は、少しづつ角度を変えて設置されている。
Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the personal identification device according to Embodiment 1 of the present invention. The personal identification device shown in FIG. 1 includes a light source 3 having a plurality of light sources 31 to 33 for irradiating transmitted light having different irradiation angles to a nail side of a finger 1 that is a subject having a fingerprint, Images of light from a plurality of light sources 31 to 33 having different irradiation angles that transmit the fingerprint of the finger 1 supported by the finger supports 2A and 2B and the finger supports 2A and 2B that support the fingerprint surface in a non-contact state. An image pickup unit 4 for obtaining a plurality of fingerprint images corresponding to fingerprints, and a signal processing unit 5 for performing image processing on the plurality of fingerprint images from the image pickup unit 4 to select a fingerprint image having the best contrast and for personal identification. The optical axes of the light sources 31 to 33 are installed at slightly different angles.

ここで、前記撮像部4としては、指1を透過した光の光強度分布を得るための結像レンズ41及び例えば2次元固体撮像素子(CCD、CMOSイメージセンサ)でなる撮像素子42と、撮像素子42からの光強度分布に応じた電気信号を入力し、指紋画像を画像信号として出力する画像出力回路43とを有する。   Here, the imaging unit 4 includes an imaging lens 41 for obtaining a light intensity distribution of light transmitted through the finger 1, an imaging element 42 such as a two-dimensional solid-state imaging element (CCD, CMOS image sensor), and imaging. An image output circuit 43 that inputs an electrical signal corresponding to the light intensity distribution from the element 42 and outputs a fingerprint image as an image signal is provided.

次に、上記構成に係る個人識別装置の動作について説明する。指1が指支持部2A,2Bに置かれたことを検知すると、まず始めに、光源31を点灯し、指1を透過した透過光を撮像部4で読み取り、指紋画像を信号処理部5で処理する。次に、光源32を点灯し、同様にして指紋画像を採取する。さらに、最後に、光源33を点灯し、同様にして指紋画像を採取する。   Next, the operation of the personal identification device according to the above configuration will be described. When it is detected that the finger 1 is placed on the finger supports 2A and 2B, first, the light source 31 is turned on, the transmitted light transmitted through the finger 1 is read by the imaging unit 4, and the fingerprint image is read by the signal processing unit 5. To process. Next, the light source 32 is turned on, and a fingerprint image is collected in the same manner. Finally, the light source 33 is turned on and a fingerprint image is collected in the same manner.

上述したようにして採取された3枚の指紋画像は、信号処理部5に入力され、信号処理部5において、コントラストの最もよい画像が選択され、指紋の登録・照合用に使用される。   The three fingerprint images collected as described above are input to the signal processing unit 5, and an image with the best contrast is selected by the signal processing unit 5 and used for fingerprint registration / collation.

したがって、実施の形態1によれば、照射角度の異なる複数の光源31〜33を順次点灯させて指紋画像を撮像するようにしたので、指先の形状・太さ等の個人差によらず安定した透過画像が得られ、最もコントラストの良い指紋画像を得て個人識別することができる。   Therefore, according to the first embodiment, since a plurality of light sources 31 to 33 having different irradiation angles are sequentially turned on to capture a fingerprint image, it is stable regardless of individual differences such as fingertip shape and thickness. A transparent image is obtained, and a fingerprint image with the highest contrast can be obtained to identify the individual.

実施の形態2.
図2は、この発明の実施の形態2に係る個人識別装置の構成を示すブロック図である。図2に示される個人識別装置において、図1に示す構成と同一部分は同一符号を付してその説明は省略する。図2に示す実施の形態2においては、光源3は、単一の光源でなり、指支持部2A,2Bは、光源3との距離を順次可変とする可動式の指支持部でなる点が、図1に示す実施の形態1と異なる。
Embodiment 2. FIG.
FIG. 2 is a block diagram showing the configuration of the personal identification device according to Embodiment 2 of the present invention. In the personal identification device shown in FIG. 2, the same parts as those shown in FIG. In the second embodiment shown in FIG. 2, the light source 3 is a single light source, and the finger support portions 2 </ b> A and 2 </ b> B are movable finger support portions whose distance from the light source 3 can be sequentially changed. This is different from the first embodiment shown in FIG.

ここで、指支持部2A,2Bは、図2の指支持部2Aに示すように、指先を置くと下に下がる可動部21と、可動部21が一定値以下に下がったことを検出するセンサー部22とで構成されている。   Here, as shown in the finger support 2A in FIG. 2, the finger supports 2A and 2B are a movable part 21 that is lowered when a fingertip is placed, and a sensor that detects that the movable part 21 has fallen below a certain value. Part 22.

そして、撮像部4は、可動する指支持部2A,2Bに支持された指1の指紋を透過する光源3からの光を撮像して指紋に対応する複数の指紋画像を得るようになされ、信号処理部5は、撮像部4からの複数の指紋画像を画像処理してコントラストが最も良い指紋画像を選択して個人識別するようになされている。   The imaging unit 4 captures light from the light source 3 that transmits the fingerprint of the finger 1 supported by the movable finger support units 2A and 2B, and obtains a plurality of fingerprint images corresponding to the fingerprints. The processing unit 5 performs image processing on a plurality of fingerprint images from the imaging unit 4 and selects a fingerprint image having the best contrast to identify the individual.

次に、上記構成に係る個人識別装置の動作について説明する。指支持部2A,2Bに指1が置かれたことを検知すると、光源3を点灯し、指1を透過した透過光をレンズ41やCCD42などのセンサーで構成された撮像部4で読み取り、その画像は信号処理部5に送られる。   Next, the operation of the personal identification device according to the above configuration will be described. When it is detected that the finger 1 is placed on the finger support portions 2A and 2B, the light source 3 is turned on, and the transmitted light that has passed through the finger 1 is read by the imaging unit 4 including sensors such as the lens 41 and the CCD 42. The image is sent to the signal processing unit 5.

次に、指1を指支持部2A,2Bに置くことで、指支持部2A,2Bの指先部分の可動部21が少しずつ下にさがってくる。このとき、同様にして、一定間隔で順次透過光を撮像部4で読み取り、その画像は、信号処理部5へ送られる。   Next, by placing the finger 1 on the finger support portions 2A and 2B, the movable portion 21 of the fingertip portion of the finger support portions 2A and 2B is gradually lowered. At this time, similarly, the transmitted light is sequentially read by the imaging unit 4 at regular intervals, and the image is sent to the signal processing unit 5.

この動作は、可動部21が一定範囲以下に下がったことをセンサー部22が検出するまで繰り返す。信号処理部5では、送られてきた画像の中でコントラストが最もよい画像が選択され、指紋の登録・照合用に使用される。   This operation is repeated until the sensor unit 22 detects that the movable unit 21 has fallen below a certain range. In the signal processing unit 5, an image having the best contrast is selected from the transmitted images and used for fingerprint registration / collation.

なお、図2に示す実施の形態2では、可動部21の構成として、バネによる実施の形態を示したものであるが、モータによる可動部の駆動などに置き換えてもよい。   In the second embodiment shown in FIG. 2, the movable portion 21 is configured with a spring as an example, but may be replaced with a drive of the movable portion with a motor.

従って、実施の形態2によれば、指支持部2A,2Bを、光源3との距離を順次可変とする可動式の指支持部で構成し、指を置いたときに指先で押し下げる操作により、画像を連続撮像するようにしたので、指先の形状・太さ等の個人差によらず安定した透過画像が得られ、最もコントラストの高い画像を登録・照合用に採用することにより、簡単にかつ低コストで高性能な装置を構成することができる。   Therefore, according to the second embodiment, the finger support portions 2A and 2B are configured with a movable finger support portion whose distance from the light source 3 can be sequentially changed, and when the finger is placed, the finger support portions 2A and 2B are pushed down with the fingertip. Since images are continuously captured, a stable transmission image can be obtained regardless of individual differences such as the shape and thickness of the fingertips, and the highest contrast image can be used for registration and verification. A high-performance apparatus can be configured at low cost.
