Abstract: A distance measurement device measures a distance to a subject by emitting directional light to the subject and receiving reflection light of the directional light, acquires a correspondence relation between an in-provisional-image irradiation position, which corresponds to an irradiation position of the directional light onto the subject, within a provisional image acquired by provisionally imaging the subject whenever each of a plurality of distances is provisionally measured and a distance which is provisionally measured by using the directional light corresponding to the in-provisional-image irradiation position, derives an in-actual-image irradiation position, within an actual image acquired by performing actual imaging based on the acquired correspondence relation, and performs a predetermined process as a process of suppressing a decrease in accuracy of the in-actual-image irradiation position in a case where the distance acquired through the actual measurement is out of a range of a distance specified by the correspondence relation.

Abstract: Disclosed are a distance image acquisition apparatus and a distance image acquisition method capable of achieving high distance measurement accuracy and omitting wasteful imaging or calculation. The distance image acquisition apparatus (10) includes a distance image sensor (14), a drive mode setting unit (20A), a distance image generation unit (20B), a pulse light emission unit (22), and an exposure control unit (24). The exposure control unit (24) controls emission and non-emission of pulse light emitted from the pulse light emission unit (22) according to a drive mode set by the drive mode setting unit (20A), and controls exposure in the distance image sensor (14). The distance image generation unit (20B) performs calculation processing of a sensor output acquired from the distance image sensor (14) according to the drive mode set by the drive mode setting unit (20A) to generate a distance image corresponding to a distance of a subject.
