Abstract: Disclosed are a distance image acquisition apparatus and a distance image acquisition method capable of acquiring a distance image with satisfactory accuracy based on a first pattern projected from a host apparatus even in a case where patterns of structured light having the same shape are projected simultaneously from the host apparatus and another apparatus. A distance image acquisition apparatus (10) includes a projection unit (12) which projects a pattern of structured light, a light modulation unit (22) which modulates a switching timing of projection and non-projection of the pattern with a code, an imaging unit (14) which is provided in parallel with and apart from the projection unit (12) by a baseline length, performs imaging in synchronization with a projection period and a non-projection period of the pattern, and generates a first captured image captured in the projection period of the pattern and a second captured image captured in the non-projection period of the pattern, a differential image generation unit (20D) which generates a differential image of the first captured image and the second captured image, a pattern extraction unit (20A) which extracts the pattern from the differential image, and a distance image acquisition unit (20B) which acquires a distance image indicating a distance of a subject within a distance measurement region based on the pattern extracted by the pattern extraction unit (20A).

Abstract: A measurement area selection circuit has an irradiation field determination unit, an object area determination unit, and a measurement area determination unit. The irradiation field determination unit determines an irradiation field of an imaging surface of an FPD. The object area determination unit determines an object area from a comparison result between a first expected received dose of a directly exposed area and dose detection signals of detection pixels situated in the irradiation field. The measurement area determination unit determines a measurement area, which corresponds to a region of interest, from a comparison result between a second expected received dose of the measurement area and the dose detection signals of the detection pixels situated in the irradiation area and the object area. The dose detection signals of the detection pixels situated in the measurement area are used for AEC.
