Title (EN) TAKING LENS SYSTEM
(FR) SYSTÈME D'OBJECTIF DE PRISE DE VUES
(KO) 촬영 렌즈계
Abstract:
(EN) This invention relates to a small taking lens which is small because pixel sizes are small, but can implement a high-resolution camera by being combined with a high-resolution image sensor. The small taking lens of the present invention comprises in order from an object side: an aperture; a first lens which has positive refractive power and has a convex shape on the object side; a second lens which has negative refractive power, has a paraxial plane shape on the object side, and has an aspherical shape on the upper side; a third lens which has positive refractive power and has a concave meniscus shape on the object side; and a fourth lens which has negative refractive power and has a convex shape on the object side, wherein the Abbe numbers of the first, third and fourth lenses are between 40 and 50.
(FR) La présente invention concerne un petit objectif de prise de vues qui est de petite taille du fait que les tailles de pixel sont petites, mais qui peut mettre en œuvre un appareil de prise de vues à haute résolution en étant combiné avec un capteur d'images haute résolution. Le petit objectif de prise de vues de la présente invention comprend dans l'ordre à partir d'un côté objet : une ouverture; une première lentille qui possède une puissance de réfraction positive et a une forme convexe sur le côté objet; une deuxième lentille qui possède une puissance de réfraction négative, a une forme plane paraxiale sur le côté objet, et a une forme asphérique sur le côté supérieur; une troisième lentille qui possède une puissance de réfraction positive et a une forme de ménisque concave sur le côté objet; et une quatrième lentille qui possède une puissance de réfraction négative et a une forme convexe sur le côté objet, les nombres d'Abbe des première, troisième et quatrième lentilles étant compris entre 40 et 50.
(KO) 이 발명은 픽셀사이즈가 작아서 소형이면서도 높은 해상도를 갖는 상센서와 결합하여서 고해상도 카메라의 구현이 가능하게 하는 소형 촬영 렌즈에 관한 것이다. 본 발명의 소형 촬영렌즈는, 물체측으로부터 순차적으로, 조리개, 정의 굴절력을 갖고 물체측이 볼록 형태의 제1렌즈, 부의 굴절력을 갖고, 물체측이 근축평면 형태이고, 상측이 비구면 형태의 제2렌즈, 정의 굴절력을 갖고 물체측이 오목인 매니스커스 형태의 제3렌즈, 및 부의 굴절력을 갖고, 물체측이 볼록인 제4렌즈를 포함하고, 상기 제1, 3, 4 렌즈의 아베수는 40 내지 50이다.
