    Abstract: A distance-measuring imaging device includes: a drive controller that outputs a light emission control signal for instructing emission of pulsed light and an exposure control signal for instructing exposure to reflected light; an image capturer that includes a plurality of pixels and outputs an exposure signal of each of the plurality of pixels that has been exposed at a timing of the exposure control signal; a pixel calculator that generates a composite signal with a pixel filter that combines exposure signals of adjacent pixels among the plurality of pixels using a weight coefficient for the exposure signal; and a time-of-flight (TOF) calculator that generates a distance image, based on the composite signal. The pixel calculator includes at least two pixel filters having different composite scale factors, and selects the pixel filter from the at least two pixel filters.
