Abstract

The invention discloses a camera lens group, an image pickup device and an electronic device. The camera lens group sequentially includes a first lens with refractive power, a second lens, a third lens, a fourth lens, and a fifth lens from the object side to the image side. lens and sixth lens. The first lens has positive refractive power, and its object-side surface is convex at the near optical axis. The second lens has negative refractive power. The third lens has positive refractive power, and its two surfaces are both aspherical. The fourth lens has refractive power, and its two surfaces are both aspherical. The fifth lens has negative refractive power, and its two surfaces are both aspherical. The sixth lens has positive refractive power, its object-side surface is concave at the near optical axis, its image-side surface is convex at the near optical axis, and both surfaces are aspherical. There is an air space between any two adjacent lenses among the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens on the optical axis. The invention also discloses an image pickup device with the optical camera lens group and an electronic device with the image pickup device.

Description

technical field [0001] The invention relates to a camera lens group, an image pickup device and an electronic device, in particular to a camera lens group and an image pickup 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 been increasing day by day, and the photosensitive elements of general photographic lenses are nothing more than charge coupled devices (CCD) or complementary metal oxide semiconductor elements. (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor) two types, and with the improvement of semiconductor process technology, the pixel size of the photosensitive element is reduced. In addition, today's electronic products are developing with good functions and thin, light and short appearance. Therefore, miniaturized photographic lenses with good imaging quality have become the mainstream in the current...
