Abstract
An embodiment of the present invention provides an image pick-up lens system, an imaging module having the image pick-up lens system, and a terminal having the imaging module. The system includes the following lenses arranged sequentially from an object side to an image side: a first lens with positive focal power; a second lens with negative power, having a convex object-side surface; a third lens with negative power; a fourth lens; a fifth lens with positive power, having a convex image-side surface; and a sixth lens having a concave image-side surface near an optical axis. With proper focal power allocation and a large aperture diameter configuration, the length of the lens system is effectively shortened, aberration is reduced, and imaging quality is improved.
