    • A method and an apparatus for distinguishing a latent fingerprint is provided to prevent a fingerprint recognition apparatus from mis-recognizing a latent fingerprint as a fingerprint of a biomass due to a fingerprint residual on an imaging surface of an optical fingerprint input apparatus. According to the present invention, there is provided a backlight control device for controlling switching on and off of the backlight; an image acquisition device for acquiring a fingerprint image without illuminating the backlight onto the imaging surface; a fingerprint detection device for detecting the existence of a fingerprint from the image acquired by the image acquisition device; and a device for determining that the fingerprint, if detected by the fingerprint detection device, is a latent fingerprint detected due to an external light.
    • 提供了用于区分潜在指纹的方法和装置,以防止指纹识别装置由于光学指纹输入装置的成像表面上的指纹残留而误认为潜在指纹作为生物质的指纹。 根据本发明,提供了一种用于控制背光的接通和断开的背光控制装置; 用于获取指纹图像而不将所述背光照射到所述成像表面上的图像获取装置; 指纹检测装置,用于从由图像获取装置获取的图像中检测指纹的存在; 以及用于确定如果由指纹检测装置检测到的指纹是由于外部光检测到的潜在指纹的装置。
