Abstract

The present invention discloses an image capturing optical lens system, an image capturing device and an electronic device. The image capturing optical lens system sequentially includes a first lens, a second lens, a third lens, a fourth lens and fifth lens. The second lens has positive refractive power. The third lens has negative refractive power. The fourth lens has positive refractive power. The fifth lens has negative refractive power, its image-side surface is concave at the near optical axis, its image-side surface has at least one convex critical point at off-axis, and both its object-side surface and image-side surface are aspherical. The total number of lenses in the image capture optical lens system is five. The image capture optical lens system can meet the requirements of miniaturization, large aperture and large viewing angle at the same time. The invention also discloses an image capturing device with the above-mentioned image capturing optical lens system and an electronic device with the image capturing device.

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...
