Optical image capturing module

Abstract

An optical image capturing module includes a lens assembly and a circuit assembly including a circuit substrate and an image sensing component electrically connected to the circuit substrate via signal transmission elements. The lens assembly includes a fixed base disposed on the circuit substrate, a movable base, and a lens group. The fixed base made of an opaque material has a focusing hole penetrating through two ends of the fixed base to be hollow, and is disposed on the circuit substrate, so the image sensing component is located in the focusing hole. The movable base disposed in the focusing hole could move relative to the fixed base. The lens group including at least two lenses having refractive power is disposed in a receiving hole of the movable base, thereby light could pass through the lens group and project onto a sensing surface of the image sensing component.

Description

technical field [0001] The present invention relates to an optical imaging module, and in particular to an optical imaging module applied to electronic products and capable of miniaturization. Background technique [0002] In recent years, with the rise of portable electronic products with photography functions, the demand for optical systems has increased day by day. The photosensitive element of the general optical system is nothing more than two types of photosensitive coupling device (Charge Coupled Device; CCD) or complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor; CMOSSensor), and with the progress of semiconductor process technology, making The pixel size of the photosensitive element is reduced, and the optical system is gradually developing towards a high-pixel direction, so the requirements for image quality are also increasing. [0003] The optical system traditionally mounted on portable devices, due to the continuous...
