Abstract: A three-dimensional motion obtaining apparatus includes: a light source; a charge amount obtaining circuit that includes pixels and obtains, for each of the pixels, a first charge amount under a first exposure pattern and a second charge amount under a second exposure pattern having an exposure period that at least partially overlaps an exposure period of the first exposure pattern; and a processor that controls a light emission pattern for the light source, the first exposure pattern, and the second exposure pattern. The processor estimates a distance to a subject for each of the pixels on the basis of the light emission pattern and on the basis of the first charge amount and the second charge amount of each of the pixels obtained by the charge amount obtaining circuit, and estimates an optical flow for each of the pixels on the basis of the first exposure pattern, the second exposure pattern, and the first charge amount and the second charge amount obtained by the charge amount obtaining circuit.
