Abstract[English]
Provided is an optical system that can simultaneously realize miniaturization of a camera using a large image sensor and an autofocus function that realizes a macro function, and an electronic device having them. The optical system includes the first reflecting member provided on the object side and the second reflecting member provided on the imaging surface side. Each of the first reflecting member and the second reflecting member have lens shapes having refractive power on an incident surface and an emission surface. In one embodiment, the optical system includes the first lens group including a first reflecting member and having positive refractive power, the second lens group having the positive refractive power, and the third lens group including a second reflecting member and having negative refractive power.[French]
L'invention concerne un système optique qui peut simultanément réaliser la miniaturisation d'une caméra à l'aide d'un grand capteur d'image et une fonction de mise au point automatique qui réalise une macro-fonction, ainsi qu'un dispositif électronique le comprenant. Le système optique comprend le premier élément réfléchissant disposé sur le côté objet et le second élément réfléchissant disposé sur le côté surface d'imagerie. Chacun du premier élément réfléchissant et du second élément réfléchissant a des formes de lentilles ayant une réfringence sur une surface incidente et une surface d'émission. Selon un mode de réalisation, le système optique comprend le premier groupe de lentilles comprenant un premier élément réfléchissant et ayant une réfringence positive, le deuxième groupe de lentilles ayant la réfringence positive, et le troisième groupe de lentilles comprenant un second élément réfléchissant et ayant une réfringence négative.
