Abstract

An imaging optical 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. 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 negative refractive power. The fifth lens element has an object-side surface being concave in a paraxial region thereof. The sixth lens element with negative refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, and the image-side surface of the sixth lens element has at least one critical point in an off-axis region thereof. When specific conditions are met, the optical lens group for image capturing can simultaneously meet the requirements of miniaturization and wide viewing angle. The invention further discloses an image capturing device with the optical lens assembly for image capturing and an electronic device with the image capturing device.

Description

technical field [0001] The present invention relates to an optical lens group for image capturing, an image capturing device and an electronic device, in particular to an optical lens group for image capturing and an image capturing device suitable for electronic devices. 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 lens in the past is not easy to balance among the requirements of imaging quality, sensitivity, aperture size, volume or viewing angle, the present invention provides an optical lens to meet the req...
