Optical sensing module, optical sensing and image capturing architecture, and method for optically scanning fingerprints with a portable communications system

摘要

An optical sensing module, an optical sensing and image capturing architecture, and a method for optically scanning fingerprints with a portable communications system are applied to a mobile phone to capture a group of images of a fingerprint on a finger of the user holding having the mobile phone. The optical sensing module has a light permeable device, at least one light source, and a sensing device. The sensing device has a plurality of sensors that form a line array of sensors. The optical sensing and image capturing architecture has the above optical sensing module and an image output unit. The volume of the optical sensing module is reduced for facilitating installation in the portable communications system, for fragmentally capturing a group of images of the fingerprint, and for processing of identification of the fingerprint.
