Abstract

The invention provides a photographing optical lens assembly, an image capturing apparatus and an electronic device. The photographing optical lens assembly includes seven lens elements, the seven lens elements being, in order from an object side to an 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 third lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The fourth lens element has an image-side surface being concave in a paraxial region thereof. The sixth lens element with positive refractive power has an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof. The seventh lens element has an image-side surface being concave in a paraxial region thereof and having at least one critical point in an off-axis region thereof.The object-side surface and the image-side surface of the seventh lens element are both aspheric surfaces. It is easy to realize the miniaturization of a camera module, improve the relative contrast of the periphery, effectively improve the manufacturability and maintain the imaging quality.

Description

technical field [0001] The present invention relates to an imaging optical lens group, an imaging device and an electronic device, in particular to an imaging optical lens group and an imaging device applicable to the 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. [0003] 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. Because the optical lenses in the past are not easy to meet the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, etc. Therefore, the present invention provides an optical lens to meet the requirements.
