DISTANCE MEASUREMENT DEVICE AND DISTANCE MEASUREMENT METHOD

The present technology relates to a distance measurement device and a distance measurement method that can easily suppress interference. A first frame being a period that a distance to a target object is calculated includes a plurality of subframes being periods that irradiation light is emitted, and the emission of the irradiation light is controlled so that timing of head subframes differs between a first frame and a second frame following the first frame, and intervals between the subframes become constant during the period of the first frame. The present technology can be applied to a case where distance measurement for measuring a distance is performed.
