Abstract: A solid-state imaging apparatus includes a plurality of pixel circuits arranged in a matrix. Each pixel circuit includes: a photodiode; a first charge storage that stores a charge; a floating diffusion region that stores a charge; a second charge storage that stores a charge; a first transfer transistor that transfers a charge from the photodiode to the first charge storage; a second transfer transistor that transfers a charge from the first charge storage to the floating diffusion region; a first reset transistor that resets the floating diffusion region; and an accumulating transistor for accumulating a charge of the floating diffusion region in the second charge storage. The capacitance of the first charge storage is greater than the capacitance of the floating diffusion region, and the capacitance of the second charge storage is greater than the capacitance of the floating diffusion region.

Abstract: A distance measuring device is to be connected to a wave transmission module to transmit a measuring wave and a wave reception module including a first wave receiver and a second wave receiver, both of which receive the measuring wave reflected from a target. In this distance measuring device, a first wave reception period in which the first wave receiver receives the measuring wave and a second wave reception period in which the second wave receiver receives the measuring wave overlap with each other on a time axis. In addition, in this distance measuring device, a time lag is provided between respective beginning times of the first and second wave reception periods. The time lag is shorter than either the first wave reception period or the second wave reception period.

Abstract: An imaging device includes: a solid-state imaging element having a plurality of pixel cells arranged in a matrix; and a signal processing part configured to process a detection signal outputted from each of the pixel cells. The pixel cells each include an avalanche photodiode and output a voltage corresponding to a count number of photons received by the avalanche photodiode as the detection signal. The signal processing part includes a variation calculation part configured to calculate a variation between the pixel cells in the detection signal outputted from each of the pixel cells, and a correction calculation part configured to correct the detection signal outputted from each of the pixel cells, on the basis of the variation calculated by the variation calculation part.

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.
