PROBLEM TO BE SOLVED: To provide a distance image generation device that generates a distance image in which an influence of a change by noise of an amount of accumulation charging accumulated in each charging accumulation unit for each generation of the distance image is reduced even under existence of various noise.SOLUTION: The present device comprises: a light reception unit 30 that includes a photoelectric conversion element 34, and charging accumulation units 36A to 36D provided for each photoelectric element 34; and a distance image generation unit 40 that generates a distance image on the basis of charging accumulated in each charging accumulation unit. The distance image generation unit 40 is configured to: compute a value having a minimum amount of accumulation charging reduced before the processing object charging accumulation time has elapsed from an amount of accumulation charging of processing object charging accumulation time for each of the charging accumulation units 36A to 36D every a prescribed charging accumulation time; and compute a distance value up to an object 200 for each pixel on the basis of a correction amount of accumulation charging having the minimum amount of accumulation charging added to an average value of amounts of noise charging before the processing object charging accumulation time has elapsed.SELECTED DRAWING: Figure 1 |
