Abstract

An image capturing lens assembly, an imaging apparatus and an electronic device are provided. The image capturing lens assembly includes seven lens elements, which are, in order from an object side to an image side along an optical path, 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, each of the seven lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The first lens element has negative refractive power. The third lens element has positive refractive power. The seventh lens element has negative refractive power. When a specific condition is satisfied, a wide viewing angle configuration can be formed, the volume of the image capturing lens group can be compressed, and aberration can be reduced.

Description

technical field [0001] The present disclosure relates to an image capturing mirror group and an image capturing device, and in particular to a miniaturized image capturing mirror group and an image capturing device applied to an electronic device. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixels can reach a smaller size. Therefore, optical lenses with high imaging quality have become an indispensable part. With the rapid development of science and technology, the application range of electronic devices equipped with optical lenses is wider, and the requirements for optical lenses are also more diverse. Since the conventional optical lens is not easy to achieve a balance among requirements such as imaging quality, sensitivity, aperture size, volume, or viewing angle, the present disclosure provides an optical lens to meet the requirements.
