Abstract

See full text

An adding unit adds an input signal generated in a signal generating unit connected to a specific pixel electrode portion out of pixel electrode portions arranged around a certain pixel electrode portion to an input signal generated in a signal generating unit connected to the certain pixel electrode portion. A discriminating unit discriminates whether a carrier input pattern coincides with any one of a plurality of discrimination patterns, and the carrier input pattern indicates, per the pixel electrode portion, presence of any carrier received in the certain pixel electrode portion and the pixel electrode portions arranged around the certain pixel electrode portion. The counting unit increments the number of photons in the case where the discriminating unit discriminates that the carrier input pattern coincides with any one of the discrimination patterns and further the input signal output from the adding unit after addition has a value exceeding a predetermined threshold.
