Title:
PHOTON COUNT IDENTIFICATION SYSTEM, PHOTON COUNT IDENTIFICATION METHOD, AND PHOTON COUNT IDENTIFICATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/119933
Kind Code:
A1
Abstract:
A photon count identification system, according to the present invention, is provided with a plurality of pixels including photoelectric conversion elements and amplifiers which amplify charges converted by the photoelectric conversion elements and convert the result into voltage; an A/D converter which converts the voltage output by the amplifiers of the plurality of pixels into digital values; a first derivation unit which derives a provisional value of a photon count for each pixel in the plurality of pixels on the basis of the digital values; and a second derivation unit which derives a confirmed value of the photon count in the target pixels on the basis of a first probability based on optical shot noise and a second probability based on read-out noise.
