Title:
CAMERA AND IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/075527
Kind Code:
A1
Abstract:
An imaging system (1) is provided with: a planar imaging element (4) on which a plurality of pixels comprising photosensitive elements are arrayed; a mask (2) which is disposed on the front surface of the imaging element (4) and on which a pattern for modulating incident light is formed; a reading unit (5) for reading a captured image of a subject having been captured; and a recognition unit (12) for performing sex determination on attached information of the subject from the read captured image. The pattern includes a plurality of translucent portions (21) that are arrayed and that are for guiding, to one pixel, beams from a plurality of directions among beams from the subject. Accordingly, individual recognition of the subject is made impossible but recognition of individual attached information is made possible for an intended application, whereby privacy is protected.
