Abstract: An object of the present invention is to provide an imaging apparatus, an imaging method, and a program that can leave information related to gradations on a high brightness side and a low brightness side as far as possible even in a case where a scene has a wide dynamic range and a histogram of a captured image is biased. An imaging apparatus (10) includes an exposure setting unit (101), an image acquisition unit, a brightness information acquisition unit (103), a count unit that counts each of the number of darkened pixels, the number of low brightness pixels, the number of washed out pixels, and the number of high brightness pixels, a calculation unit that calculates a first ratio between the number of darkened pixels and the number of low brightness pixels and a second ratio between the number of washed out pixels and the number of high brightness pixels, and an exposure adjustment unit that adjusts a first exposure to a second exposure based on the first ratio and the second ratio calculated by the calculation unit.

Abstract: An execution unit executes a derivation process of deriving an imaging position distance, on the basis of a plurality of pixel coordinates which are present in the same planar region as an irradiation position where the directional light is emitted on the real space and which are equal to or more than three pixels specifiable at positions corresponding to each other in respective first and second captured images, irradiation position real space coordinates, a focal length, and dimensions of imaging pixels, in a case where the position of a pixel specified by the irradiation position pixel coordinates is the position of a pixel different from a pixel which is specifiable at positions corresponding to each other in the respective first and second captured images.

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).
