Claims (3)
- 지문이미지 취득장치를 이용하여 지문이미지를 취득하는 방법에 있어서,상기 지문이미지 취득장치의 지문감지소자부의 표면으로 손가락을 접촉시켜 CCD소자부로 지문이미지를 발생시키는 단계;상기 CCD소자부에서 지문이미지가 발생되어 출력되면 제어기는 지문이미지가 이미지버퍼에 입력되었는지를 확인하는 단계;상기 지문이미지가 상기 이미지버퍼에 입력되어 저장된 것으로 확인되면 상기 제어기는 이미지버퍼에 저장된 지문이미지에서 중심영역의 단위블럭을 소정 개수의 미세블럭으로 분할함과 아울러 외곽영역은 단위블럭으로 분할하여 비디오 메모리에 저장하여 지문이미지를 취득하는 단계로 구비되며,상기 미세블럭은 단위블럭에서 적어도 두 개 이상으로 분할되고, 상기 중심영역은 적어도 한 개 이상의 영역으로 설정됨을 특징으로 하는 지문이미지 취득방법.
