    摘要: A depth acquisition device (1) capable of accurately acquiring a depth to a subject includes a memory (200) and a processor (110a) performing: acquiring, from the memory (200), intensities of infrared light measured by imaging with infrared light emitted from a light source and reflected on the subject by pixels in an imaging element; generating a depth image by calculating the distance for each pixel based on the intensities; acquiring, from the memory (200), a visible light image generated by imaging, with visible light, the substantially same scene from the substantially same viewpoint at the substantially same timing as those of the infrared light image generated by imaging based on the intensities; detecting a lower reflection region showing an object having a lower reflectivity from the infrared light image in accordance with the infrared light image and the visible light image; correcting a lower reflection region in the depth image corresponding to the lower reflection region in accordance with the visible light image; and outputting the depth image with the corrected lower reflection region.

    摘要: A depth acquisition device (1) capable of accurately acquiring a depth of a subject of an image includes a memory (200) and a processor (110a). The processor (110a) performs: acquiring, from the memory (200), intensities of infrared light which have been emitted from a light source and are measured by imaging performed by receiving the infrared light reflected on a subject by pixels in an imaging element; generating a depth image by calculating a distance to the subject as a depth for each pixel based on an intensity received by the pixel; acquiring, from the memory (200), a visible light image generated by imaging a substantially same scene as that of an infrared light image, with visible light from a substantially same viewpoint and at a substantially same timing as those of imaging the infrared light image which is generated by the imaging based on the intensities of the infrared light received by the pixels; detecting, from the visible light image, an edge region including an edge along a direction perpendicular to a direction of movement of the visible light image; and correcting, in the depth image, a depth of a target region corresponding to the edge region in the depth image.

    摘要: A depth acquisition device capable of accurately acquiring a depth of an image is provided. A depth acquisition device (1) includes a memory (200) and a processor (110). The processor (110) performs: acquiring timing information indicating a timing at which a light source irradiates a subject with infrared light; acquiring an infrared light image stored in the memory (200), the infrared light image being generated by imaging a scene including the subject with the infrared light according to the timing indicated by the timing information; acquiring a visible light image stored in the memory (200), the visible light image being generated by imaging a substantially same scene as that of the infrared light image, with visible light from a substantially same viewpoint and at a substantially same imaging time of those of the infrared light image; detecting a dust region showing dust from the infrared light image; and estimating a depth of the dust region based on the infrared light image, the visible light image, and the dust region.

    摘要: The present invention provides a proton-conducting oxide comprising a perovskite crystal structure represented by a composition formula A a B 1-x B' x O 3-δ . A represents strontium. B represents zirconium. B' represents at least one selected from the group consisting of yttrium and ytterbium. The value of a is more than 0.84 and less than 1.0. The value of x is more than 0.0 and less than 0.2. The present invention provides a proton-conducting oxide having a capability to maintain high proton conductivity even if the proton-conducting oxide is exposed to the air atmosphere for a long time.
