Abstract:
Image quality of a depth map is improved in a distance measuring device for receiving intermittent light.
In a pixel array unit, a plurality of pixels for receiving predetermined intermittent light is arranged in a two-dimensional lattice pattern. A continuous light image data generating unit generates continuous light image data in which a plurality of pieces of pixel data indicating a luminance of predetermined continuous light is arranged in a two-dimensional lattice pattern on the basis of received light data of each of the plurality of pixels. A depth map generating unit generates a depth map in which distance information corresponding to each of the plurality of pixels is arranged, from the received light data and the continuous light image data.
