description The invention discloses a fingerprint identification device, a fingerprint identification method and a moire image generation method. The fingerprint identification device comprises a fingerprint sensing circuit and an image processing circuit. The fingerprint sensing circuit is configured to perform a first fingerprint sensing operation to obtain a first fingerprint image. The image processing circuit is coupled to the fingerprint sensing circuit and is configured to generate a moire-removed fingerprint image according to a moire image and the first fingerprint image and execute a fingerprint recognition program according to the moire-removed fingerprint image. 本发明公开了一种指纹识别装置、指纹识别方法及摩尔纹影像产生方法。所述指纹识别装置包括一指纹感测电路以及一图像处理电路。指纹感测电路被配置成执行一第一指纹感测操作以获得一第一指纹图像。图像处理电路耦接于所述指纹感测电路，且被配置成根据一摩尔纹图像以及所述第一指纹图像产生一去摩尔纹指纹图像以及根据所述去摩尔纹指纹图像执行一指纹识别程序。
