Abstract

An image lens is disclosed and 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 has negative refractive power. The third lens element has positive refractive power. The fourth lens element has positive refractive power. The fifth lens element has negative refractive power, the image-side surface of the fifth lens element is concave in a paraxial region thereof and an object-side surface and the image-side surface are aspheric. The sixth lens element has an image-side surface being concave in a paraxial region thereof, the image-side surface has at least one inflection point in an off-axis region thereof, and both of the object-side surface and the image-side surface of the sixth lens element are aspheric. The total number of lenses of the image lens is six. When specific conditions are met, the image lens can meet the requirements of a large viewing angle, high imaging quality and miniaturization at the same time.

Description

[0001] This application is a divisional application. The filing date of the original application is: August 26, 2016; the application number is: 201610728907.9; the title of the invention is: video lens, imaging device and electronic device. technical field [0002] The invention relates to an image lens, an image capturing device and an electronic device, in particular to an image lens and an image capturing device suitable for the electronic device. Background technique [0003] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has increased day by day, and with the advancement of semiconductor technology, the pixel size of photosensitive elements has been reduced. The short appearance is the development trend. Therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the current market. [0004] As the application of camera modules becomes more and more ex...
