Problems solved by technology

[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. To strike a balance between, so an optical lens is needed to meet the demand

Abstract

The present invention provides an imaging lens system, an image pickup device and an electronic device, wherein the imaging lens system includes seven lenses, and the seven lenses are in order from the object side to the image side: a first lens; a second lens; a a third lens; a fourth lens; a fifth lens; a sixth lens; and a seventh lens. Among the first lens to the seventh lens, each lens includes an object side facing the object side direction and an image side facing the image side direction, the first lens has positive refractive power, and the seventh lens image side is on the low beam The axis is concave and has at least one inflection point off the axis. The imaging lens system provided by the present invention can strike a balance among requirements such as imaging quality, sensitivity, aperture size, volume or viewing angle.

Description

technical field [0001] The present invention relates to an imaging lens system and an image capturing device, in particular to an imaging lens system and an image capturing device applicable to electronic devices. Background technique [0002] With the improvement of semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the size of 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. To strike a balance, so an optical lens is needed to meet the requirements.
