Abstract

The invention discloses an image pickup lens group. The image pickup lens group is of a seven-piece lens structure. The first lens and the seventh lens both have negative refractive power; the secondlens and the sixth lens both have positive refractive power; the object side surface of the first lens is a convex surface near the optical axis of the image pickup lens group; the image side surfaceof the fourth lens is a concave surface the near optical axis; the object side surface of the fifth lens is a concave surface near the optical axis; and the image side surface of the seventh lens is aconcave surface near the optical axis. The ratio of a distance between the first lens and the second lens on the optical axis and a distance between the fifth lens and the sixth lens on the optical axis is reasonably defined, so that the spatial arrangement of each lens can be balanced, and therefore, the degree of matching between the object side end lenses of the image pickup lens group can beimproved, and sufficient intervals are left between the image side end lenses of the image pickup lens group so as to reconcile aberrations. The image pickup lens group has the advantages of large aperture, high pixel, high resolution, and excellent field angle, and the like. The image pickup lens group can realize good imaging quality and meet application requirements. The invention also discloses an electronic device.

Description

technical field [0001] The invention relates to the technical field of optical imaging devices, in particular to an imaging lens group. The invention also relates to an electronic device. Background technique [0002] With the rapid upgrading of related consumer electronic products such as smart phones, portable computers and tablet devices, the market has higher and higher requirements for the quality of optical imaging lenses of electronic products. With the improvement of semiconductor manufacturing technology, the pixel size of the photosensitive device has been reduced. Correspondingly, the imaging lens group is gradually developing into the high-pixel field, so the requirements for its imaging quality are also increasing. [0003] Traditional lenses mounted on portable products mostly use three-element or four-element lens structures. As the market’s requirements for lens pixels and imaging quality continue to rise, existing optical camera lenses can no longer meet hi...
