Abstract

The invention provides an optical image capturing system, an imaging apparatus and an electronic device. The optical image capturing system includes five lens elements, the five lens elements being, in order from an object side to an image side: a first lens element; a second lens element having positive refractive power; a third lens element having positive refractive power; a fourth lens element; and a fifth lens element having an image-side surface being concave in a paraxial region thereof and at least one convex critical point in an off-axis region of the image-side surface thereof. Through distributing the second lens and the third lens which have positive refractive power, and moderately adjusting lens gaps, a wide viewing angle photography module with high imaging quality and micromation is achieved.

Description

technical field [0001] The present invention relates to an optical image capture system and an image capture device, in particular to an optical image capture system and an image capture device applicable to electronic devices. Background technique [0002] With the advancement of technology, the application range of electronic devices with camera modules is wider, and camera modules with high imaging quality are also an indispensable part, and the development of electronic devices is more multi-functional.
