The invention further discloses the image capturing device equipped with the optical lens set for shooting, and the electronic device equipped with the image capturing device.

Description

technical field [0001] The invention relates to an optical lens group for imaging, an image capturing device and an electronic device, in particular to an optical lens group for imaging and an image capturing device suitable for the electronic device. Background technique [0002] In recent years, with the vigorous development of miniaturized camera lenses, the demand for miniature imaging modules is increasing day by day, and the photosensitive element of general camera lenses is nothing more than a charge coupled device (CCD) or a complementary metal oxide semiconductor element. (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor) two types, and with the improvement of semiconductor technology, the pixel size of the photosensitive element is reduced, and the development trend of today's electronic products is good function and thin, light and small appearance, so , Miniaturized camera lenses with good imaging quality have become the mainstream in the current marke...
