Problems solved by technology

[0003] Traditional miniature lenses focus on the pursuit of miniaturization, so the imaging quality is often sacrificed
However, high-quality imaging systems on the market mostly adopt a multi-chip structure and are equipped with spherical glass lenses. This configuration not only makes the lens too bulky to be easily carried, but also the high unit price of the product is also unfavorable for the application of various devices and products. The known optical system can no longer meet the current trend of technological development

Abstract

The invention discloses an optical lens group used for image photographing, an image capture device and an electronic device. The optical lens group used for image photographing comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens which are arranged from an object side to an image side in turn. The first lens has positive refraction power, and the position, which is near the optical axis, of the object side surface of the first lens is a convex surface. The second lens has a negative refraction power. At least one surface of the object side surface and the image side surface of the sixth lens is an aspheric surface, and at least one surface includes at least one point of inflexion. The object side surface and the image side surface of the seventh lens are aspheric surfaces. When the specific condition is met, the optical lens group used for image photographing is enabled to have a telescope function and an aberration reducing function and effectively control the total length so as to achieve the requirement of micromation. The invention also discloses an image capture device having the optical lens group used for image photographing and an electronic device having the image capture device.

Description

technical field [0001] The present invention relates to an optical lens group for imaging and an image capturing device, and in particular to a miniaturized optical lens group for imaging and an image capturing device applied to an electronic device. Background technique [0002] As the application of camera modules becomes more and more extensive, installing camera modules in various smart electronic products, vehicle devices, identification systems, entertainment devices, sports devices and home intelligent assistance systems is a major trend in future technological development. And in order to have a wider use experience, smart devices equipped with more than one lens have gradually become the mainstream of the market. In order to meet different application requirements, lens systems with different characteristics have been developed. [0003] Traditional miniature lenses focus on the pursuit of miniaturization, so the imaging quality is often sacrificed. However, high-q...
