Abstract: A generation system includes a liquid crystal shutter that forms a coded aperture part and a depth calculating unit that uses a captured image acquired by an imaging device to calculate a depth for each unit area of a depth map. The coded aperture part includes an aperture pattern including a transmissive area having a first light transmittance, a semi-transmissive area having a second light transmittance lower than the first light transmittance, and a shielding area having a third light transmittance lower than the second light transmittance. This serves to reduce the number of times of capturing an object required for generating a depth map, thereby increasing situations in which the generation system is used.
