Abstract: A distance-image obtaining method includes: (A) setting a plurality of distance-divided segments in a depth direction, and (B) obtaining a distance image based on each of the plurality of distance-divided segments set. The obtaining of the distance image includes: obtaining a plurality of distance images by imaging two or more of the plurality of distance-divided segments, to obtain a first distance image group; and obtaining a plurality of distance images by imaging distance-divided segments, among the plurality of distance-divided segments, in a phase different from a phase of the two or more of the plurality of distance-divided segments, to obtain a second distance image group.

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 apparatus changes a multiplication factor of an avalanche photodiode (APD) at one of (i) a first timing subsequent to an exposure period of a first frame in a first vertical scanning period and a readout period of the first frame in a second vertical scanning period, and previous to an exposure period of a second frame in a third vertical scanning period, and (ii) a second timing subsequent to an exposure period of the first frame in the first vertical scanning period, and previous to a readout period of the first frame and an exposure period of the second frame which are provided in parallel in the second vertical scanning period.
