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 () includes a distance image sensor (), a drive mode setting unit (A), a distance image generation unit (B), a pulse light emission unit (), and an exposure control unit (). The exposure control unit () controls emission and non-emission of pulse light emitted from the pulse light emission unit () according to a drive mode set by the drive mode setting unit (A), and controls exposure in the distance image sensor (). The distance image generation unit (B) performs calculation processing of a sensor output acquired from the distance image sensor () according to the drive mode set by the drive mode setting unit (A) to generate a distance image corresponding to a distance of a subject.
