  • Patent number: 10812729
    Abstract: A solid-state imaging device includes a detector, a count value storage, and a reader. The detector includes an avalanche amplification type light receiving element that detects a photon, and a resetter that resets an output potential of the light receiving element, and outputs a digital signal that indicates the presence or absence of incidence of a photon on the light receiving element. The count value storage performs counting by converting the digital signal output from the detector to an analog voltage, and stores the result of counting as a count value. The reader outputs an analog signal indicating the count value.
