Abstract
A distance measurement device includes: an image capturer that captures N segmental images corresponding to N segmental distances into which a distance measurement range is divided; and a range image generator that generates a range image from the N segmental images. The range image generator determines: among segmental pixels included in the N segmental images, a segmental pixel having a maximum signal value from N segmental pixels at the same pixel position among pixel positions; a value indicating a segmental distance of the segmental pixel having the maximum signal value to be a distance value of the pixel position of the range image, when the maximum signal value is greater than or equal to a threshold; and a value indicating a value outside the distance measurement range to be the distance value of the pixel position of the range image, when the maximum signal value is less than the threshold.
