Abstract
A depth acquisition device includes a memory and a processor performing: acquiring, from the memory, intensities of infrared light measured by imaging with infrared light emitted from a light source and reflected on a 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, 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; 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 corresponding lower reflection region in the depth image in accordance with the visible light image; and outputting the depth image with the corrected lower reflection region.
