Ranging sensor

A ranging sensor of a TOF method, which operates in cooperation with at least one camera module, measures time during which a beam radiated to a space is reflected by a target and returned, and generates distance information of the target for generating three-dimensional positional information by combining the distance information with image information acquired by the camera module, the ranging sensor comprising:

• a light-emitting unit that includes a plurality of light-emitting elements arranged in plane and radiates, toward subspaces obtained by dividing the space, light from the light-emitting elements, which are allocated to the subspaces, with the light formed into a beam by a light emitting lens system;
• a light-receiving unit that includes a plurality of light-receiving elements arranged in plane, and receives reflected light beams from the subspaces and forms images of the reflected light beams on the light-receiving elements, which are allocated to the subspaces, by a light receiving lens system;
• and
• a space control unit that independently controls each element group that includes at least one light-emitting element and at least one light-receiving element that are allocated to a common one of the subspaces.
