取像用光学镜组、取像装置及电子装置
摘要：
本发明揭露一种取像用光学镜组、取像装置及电子装置，取像用光学镜组，由物侧至像侧依序包含第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜与第七透镜。第一透镜具有正屈折力。第六透镜像侧表面具有至少一反曲点。第七透镜像侧表面于近光轴处为凹面，其物侧表面与像侧表面皆为非球面，其像侧表面具有至少一反曲点。本发明还公开具有上述取像用光学镜组的取像装置及具有取像装置的电子装置，借此，可调控周边光线入射成像面的入射角度，使影像周边有足够亮度，并强化周边影像校正，以达超高分辨率。
摘要（英）：

A photographing optical lens assembly includes, in order from object side to image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element. The first lens element has positive refractive power. The second, third, fourth and fifth lens elements have refractive power. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region, wherein an object-side surface and the image-side surface of the sixth lens element are both aspheric, and the image-side surface has at least one inflection point. The seventh lens element with refractive power has an image-side surface being concave in a paraxial region, wherein an object-side surface and the image-side surface of the seventh lens element are both aspheric, and the image-side surface has at least one inflection point.
