Title (EN) CMOS IMAGE SENSOR CAPABLE OF OBTAINING HIGH-QUALITY IRIS IMAGE IN OUTDOOR PHOTOGRAPHING AS WELL AS INDOOR PHOTOGRAPHING WHEN PHOTOGRAPHING IS PERFORMED USING WAVELENGTH BAND HAVING HIGHER SUN LIGHT ABSORPTION THAN ADJACENT WAVELENGTH BANDS IN INFRARED BAND, SINCE QUANTUM EFFICIENCY INCREASES IN CORRESPONDING WAVELENGTH BAND
(FR) CAPTEUR D'IMAGE CMOS EST CAPABLE D'OBTENIR UNE IMAGE D'IRIS DE HAUTE QUALITÉ EN PHOTOGRAPHIE D'EXTÉRIEUR AINSI QU'EN PHOTOGRAPHIE D'INTÉRIEUR LORSQUE LA PHOTOGRAPHIE EST RÉALISÉE EN UTILISANT UNE BANDE DE LONGUEUR D'ONDE PRÉSENTANT UNE ABSORPTION DE LUMIÈRE SOLAIRE PLUS ÉLEVÉE QUE CELLES DES BANDES DE LONGUEUR D'ONDE ADJACENTES DANS LA BANDE INFRAROUGE, ÉTANT DONNÉ QUE L'EFFICACITÉ QUANTIQUE AUGMENTE EN BANDE DE LONGUEUR D'ONDE CORRESPONDANTE
(KO) 적외선 대역 중 태양광의 흡수율이 인접 파장대역에 비해 높은 파장대역에서의 양자효율이 향상되어 해당 파장대역을 포함하여 촬영시 실내뿐만 아니라 실외에서도 고품질 홍채이미지 획득이 가능한 CMOS 이미지 센서
Abstract: front page image
(EN) The present invention relates to an image sensor which is capable of obtaining a high-quality iris image in outdoor photographing as well as indoor photographing, and shows an improved quantum efficiency in a wavelength band having a higher sun light absorption than adjacent wavelength bands in the infrared band. Accordingly, noise attributable to sun light can be reduced in outdoor iris photographing, and a high-quality iris image can be obtained.
(FR) La présente invention concerne un capteur d'image qui est capable d'obtenir une image d'iris de haute qualité en photographie d'extérieur ainsi qu'en photographie d'intérieur, et présente une efficacité quantique améliorée dans une bande de longueur d'onde qui présente une absorption de lumière solaire plus élevée que celles des bandes de longueur d'onde adjacentes dans la bande infrarouge. En conséquence, le bruit attribuable à la lumière solaire peut être réduit dans la photographie d'iris en environnement extérieur, et une image d'iris de haute qualité peut être obtenue.
(KO) 본 발명은 실내뿐만 아니라 실외에서도 고품질 홍채이미지 획득이 가능한, 적외선 대역 중 태양광의 흡수율이 인접 파장대역에 비해 높은 파장대역에서의 양자효율이 향상된 이미지 센서에 관한 것이다. 이에 따라, 실외에서 홍채 촬영시 태양광에 의한 노이즈가 저감되고, 고품질 홍채이미지의 획득이 가능하다.
