Abstract

The present invention discloses an imaging lens system. The imaging lens system includes, 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 and a sixth lens element. The first lens element with negative refractive power has an image-side surface being concave in a paraxial region thereof. The second lens element with negative refractive power has an object-side surface being concave in a paraxial region thereof. 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 positive refractive power. The fifth lens element with negative refractive power has an image-side surface being concave in aparaxial region thereof. The sixth lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof.

Description

technical field [0001] The present invention relates to an image capture system lens set, an image capture device and an electronic device, in particular to an image capture system lens set and an image capture device suitable for electronic devices. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature photographic modules has increased day by day, and with the improvement of semiconductor technology, the pixel size of photosensitive elements has been reduced. The appearance of the development trend. Therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the current market. [0003] In order to meet more diverse market demands, the specifications of camera modules are becoming increasingly stringent, and then developed into mass-produced and low-cost camera modules to be used in a wider range of products, such as: Advanced Driver Assistance Syst...
