Abstract: A distance measurement device includes an imaging unit, a measurement unit that measures a distance to a subject by emitting directional light which is light having directivity to the subject and receiving reflection light of the directional light, and a deriving unit that 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 by the imaging unit whenever each of a plurality of distances is provisionally measured by the measurement unit and a distance which is provisionally measured by the measurement unit by using the directional light corresponding to the in-provisional-image irradiation position, and derives an in-actual-image irradiation position, within an actual image acquired by performing actual imaging by the imaging unit, based on the acquired correspondence relation.

Abstract: An image capturing apparatus includes: an image capturing unit that includes an imaging device in which pixels are arranged in a two-dimensional array and that outputs an image signal obtained by image capturing of a photographic subject by the imaging device; an image processing unit that generates a captured image based on the image signal; and a CPU that performs an exposure control process to determine whether an image of a moving subject is included in the captured image, that controls the amount of exposure of the imaging device by performing a first process in a case where the determination unit determines that an image of a moving subject is included in the captured image, and that controls the amount of exposure of the imaging device by performing a second process in a case where the determination unit determines that no moving-subject image is included in the captured image.

Abstract: A digital camera that includes an imaging sensor having a stop 2 arranged in front of an imaging surface includes an imaging control unit that starts exposure of pixels on the entire imaging surface at the same time and then, ends the exposure of the pixels at the same time in a state where light from a subject is incident on the imaging surface, by controlling an imaging sensor drive circuit which drives the imaging sensor, and a processor that sequentially changes an F number of the stop 2 to a plurality of values during a period from the start of the exposure until the end of the exposure. The processor controls a time in which the F number is maintained at each of the plurality of values to be a time that is based on a function indicating light transmittance characteristics of an APD filter.

Abstract: A first angle α formed between a direction normal to a white board (100) that is disposed along a plurality of reinforcing bars (2) and an imaging direction of a camera (200) and a second angle β indicating the direction of the reinforcing bar 2 which is a measurement target with respect to the imaging direction of the camera (200) are detected. In addition, a first distance D1 between the camera (200) and the white board (100) is measured by a laser distance meter provided in the camera (200). The amount of deviation D2 of the reinforcing bar (2) in the imaging direction of the camera (200) with respect to the first distance D1 is calculated on the basis of the measured first distance D1, the detected first angle α, and the detected second angle β.

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.
