An arithmetic device includes a storage unit that stores a coarse distance image indicating a parallax in units of first blocks, a first parallax search unit that uses a standard image that is an image captured by a first camera and a reference image that is an image captured by a second camera to calculate, in units of second blocks having a size equal to or smaller than that of the first block, a parallax in the standard image based on a parallax candidate that is a candidate for a parallax for each of the second blocks, and generate a detailed distance image that is a distance image in detail, and a candidate calculation unit that calculates the parallax candidate based on a parallax of a parent block that is a region having a size of the first block including the second block for which the first parallax search unit calculates a parallax, a parallax of an adjacent block that is a region having the size of the first block adjacent to the parent block, and a search condition.
