Detailed Description

In recent years, electronic products are required to be light and thin, so that it is difficult for conventional photographing lenses to satisfy both requirements of high specification and miniaturization, especially for a large aperture and a miniature lens with telescopic characteristics. However, as the optical zoom requirement becomes more stringent (increasing zoom ratio, etc.), the known prior art telephoto lens technology is gradually unable to meet the requirement (the total length is too long, the aperture is too small, the quality is insufficient or the size cannot be reduced), so that different optical characteristics or configurations with optical axis turning are required to solve. Due to the limitation of thickness of the electronic device, some optical lenses can be cut on the lens barrel or the lens, the size of the lens in a single direction is reduced by removing the part which is not used during imaging, the reduction of the thickness of the element can be met by matching with the reflecting element, and the lens has enough overall length to show the telescopic effect.

Fourteenth embodiment

Please refer to fig. 18, which is a rear view of an electronic device 1400 according to a fourteenth embodiment of the disclosure. As shown in fig. 18, the back of the electronic device 1400 includes a flash module 1410, a Time of Flight (TOF) module 1420, an image capturing device 1430, an image capturing device 1431, an image capturing device 1432, an image capturing device 1433, an image capturing device 1434, an image capturing device 1435, an image capturing device 1436, and an image capturing device 1437. The image capturing device 1430, the image capturing device 1431, the image capturing device 1432, the image capturing device 1433, the image capturing device 1434, the image capturing device 1435, the image capturing device 1436, and the image capturing device 1437 face the same direction and are vertically arranged in two rows on the back of the electronic device 1400. The flash module 1410 and the TOF (Time of Flight) module 1420 are disposed on the upper edge of the back of the electronic device 1400, and are located near the image capturing device 1434. The image capturing devices 1430, 1431 are super wide angle image capturing devices, the image capturing devices 1432, 1433 are wide angle image capturing devices, the image capturing devices 1434, 1435 are telescopic image capturing devices, the optical lens assembly for imaging according to the first embodiment of the present invention is adopted, the image capturing devices 1436, 1437 are telescopic image capturing devices, and the optical lens assembly for imaging according to the first embodiment of the present invention with a reflecting surface is adopted. The viewing angles of the image capturing devices 1430, 1431 are at least 20 degrees greater than the viewing angles of the image capturing devices 1432, 1433, and the viewing angles of the image capturing devices 1432, 1433 are at least 20 degrees greater than the viewing angles of the image capturing devices 1434, 1435, 1436, 1437, so that the viewing angles of the image capturing devices 1430, 1431 with the largest viewing angle among the image capturing devices on the back of the electronic device 1400 are at least 40 degrees greater than the viewing angles of the image capturing devices 1434, 1435, 1436, 1437 with the smallest viewing angle.

The electronic device disclosed in the foregoing is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the image capturing device of the present invention. Preferably, the electronic device may further include a control unit, a display unit, a storage unit, a temporary storage unit (RAM), or a combination thereof.

The above tables show tables of variation of values of the imaging optical lens assembly according to the embodiments of the present disclosure, but the variation of values of the embodiments of the present disclosure is obtained experimentally, and products with the same structure should still fall within the scope of the present disclosure even though different values are used, so that the descriptions and drawings described above are only for illustration and are not intended to limit the scope of the present disclosure.
