摘要： The invention provides an image shooting apparatus and an image shooting method that obtain a recovered image with high precision by using an optimal point spread function (PSF) without deriving an image shooting distance of a photographed object, an image shooting program, and a recording medium that records the image shooting program. An image shooting apparatus includes an optical system, an image shooting element configured behind the optical system; an image recovery processing portion configured to perform image processing and recovery processing on obtained image data; and a recovered image output portion configured to output a recovered image; and the image recovery processing portion includes a recovery filter storage memory configured to store multiple recovery filters pre-manufactured by using multiple point spread functions; a recovery filter processing portion configured to obtain multiple middle candidate images; and an image comment portion configured to output a middle candidate image with an optimal profile.

摘要： The present invention provides a fixed focus-type photographing apparatus, which can inexpensively and simply increase a depth of field by disposing a removable light diffusion plate in an existing lens optical system, and an optical system of the photographing apparatus. A photographing apparatus includes: an optical system, including two or more than two lenses, a diaphragm disposed between any two adjacent lenses of the lenses, and a light diffusion plate disposed at a position that is in front of a forefront first lens; and a photographing element, disposed at a position that is behind a rearmost final lens, where: the light diffusion plate includes a light diffusion surface, and a distance a from a front surface of the first lens to the diaphragm is less than a distance b from the diaphragm to the photographing element.

摘要： An image processor includes a map generator that generates a map being data including pixels each associated with depth-related information using an image captured with patterned light projected onto a target object, an edge detector that detects an edge of the target object using an image captured without patterned light projected onto the target object, and a corrector that corrects the map based on the detected edge to cause a discontinuous depth position to match a position of the edge of the target object.

摘要： A three-dimensional measurement system capable of realizing high-speed processing while increasing measurement resolution are provided. The system includes: an image capture unit including a first and second image capture units that are spaced apart; a first calculation unit calculates a parallax at first feature points in the images using distance information of a three-dimensional measurement method other than a stereo camera method or information for calculating a distance, using at least one of the first and second image capture units; and a second calculation unit calculates a parallax at second feature points based on a corresponding point for the second feature point by using the stereo camera method using the first and second image capture units, and specifies a three-dimensional shape based on the parallax at the first and second feature points. The second calculation unit sets a search area based on the parallax at the first feature points.

摘要： An image processing system includes a first light projection unit that projects, onto an object, a light pattern for specifying a three-dimensional shape; a second light projection unit that projects, onto the object, substantially uniform light, in which illumination energy is substantially uniform in a cross-sectional direction relative to a light projection direction, at substantially the same angle as in projection performed by the first light projection unit; an image capturing unit that captures images of the object; a generation unit that generates a division image by dividing components of a first captured image, which is captured while light is projected onto the object by the first light projection unit, by components of a second captured image, which is captured while light is projected onto the object by the second light projection unit; and a calculation unit that calculates three-dimensional positions on the object with use of the division image.
