Title:
OPTICAL IMAGE COLLECTION STRUCTURE, METHOD FOR DISTINGUISHING BETWEEN TRUE AND FALSE BIOLOGICAL FEATURES, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/082680
Kind Code:
A1
Abstract:
Disclosed are an optical image collection structure for biological feature recognition, an optical sensor, an image collection method, and an electrode device. The optical image collection structure comprises several Microlens regions, and the optical sensor located below the Microlens regions and provided with several pixel point regions, wherein among the several Microlens regions and the several pixel point regions, the area of one Microlens region corresponds to the area of two or more combined pixel point regions; and the Microlens region is coaxial with a photoelectric sensing region of one pixel point region directly facing the Microlens region below. The present invention can increase the amount of optical signals at a single pixel point, and can reduce the data transmission amount for images.
