Abstract

The invention discloses a photographing optical lens system, image capturing unit and electronic device. A photographing optical lens system includes five lens elements which are, 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 and a fifth lens element. The second lens element has positive refractive power. Thethird lens element has negative refractive power. The fourth lens element has positive refractive power. The fifth lens element with negative refractive power has an image-side surface being concavein a paraxial region thereof, wherein the image-side surface thereof has at least one convex critical point in an off-axial region thereof, the object-side surface and the image-side surface thereof are aspheric. The photographing optical lens system can satisfy demands of miniaturization, large aperture, and large visual angle. The invention also discloses an image capturing unit which has the photographing optical lens system, and an electronic device having the image capturing unit.

Description

technical field [0001] The invention relates to an image capturing optical lens system, an image capturing device and an electronic device, in particular to an image capturing optical lens system and an image capturing device suitable for an electronic device. Background technique [0002] 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. [0003] With the gradual popularization of smart electronic products and the development of science and technology, ordinary users have stricter requirements for camera functions. For example, users would like to use smart electronic products to take selfie photo...
