Abstract

The invention discloses an image photographing optical lens set which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are successively arranged from an object side to an image side. The first lens has a positive refracting power, and a near-optical-axis position on the object side surface of the first lens is a convex surface. The third lens has a positive refracting power; a near-optical-axis position on the object side surface of the third lens is a convex surface; and a near-optical-axis position on the image side surface is a concave surface. The fourth lens has a negative refracting power; a near-optical-axis position on the object side surface of the fourth lens is a concave surface; and a near-optical-axis position on the image side surface is a convex surface. A near-optical-axis position on the image side surface of the fifth lens is a concave surface. A near-optical-axis position on the object side surface of the sixth lens is a convex surface, and a near-optical-axis position on the image side surface is a concave surface. An off-optical-axis position on the image side surface of the sixth lens is a convex surface. The object side surface and the image side surface of the sixth lens are aspheric surfaces. The image photographing optical lens set comprises six lenses, and furthermore an air gap is arranged between two adjacent lenses in an optical axis direction. The invention further discloses an image pickup device with the photographing optical lens set, and an electronic device with the image pickup device.

Description

technical field [0001] The invention relates to an optical lens group for imaging, an imaging device and an electronic device, in particular to an optical lens group for imaging and an imaging device suitable for the 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. Short and small appearance is the development trend. Therefore, miniaturized photographic lenses with good image quality have become the mainstream in the current market. [0003] Due to the development of high-end mobile devices such as high-end smart phones, wearable devices and tablet computers in the direction of thinner and lighter in recent years, the requirements for miniaturization of camera lenses have also increased, and it has been difficult f...
