The sound image control device filters transfer functions H 3 and H 1 indicating transfer characteristics of a sound from an acoustic transducer ( 8 ) to entrances to respective ear canals ( 1 ) and ( 2 ) as well as filtering transfer functions H 4 and H 2 from an acoustic transducer ( 9 ) to the entrances to the respective ear canals ( 1 ) and ( 2 ) and generates second transfer functions H 6 and H 5 indicating transfer characteristics of a sound to the entrances to the respective ear canals ( 1 ) and ( 2 ) from a target sound source ( 11 ) at a location different from the sound sources, the sound image control device being equipped with correction filters ( 13 ) and ( 14 ) that (i) store characteristic functions E 1 and E 2 for performing filtering operations on the first transfer functions H 1, H 2, H 3, and H 4 and (ii) generate the second transfer functions H 5 and H 6 from the first transfer functions H 1, H 2, H 3, and H 4 using such characteristic functions E 1 and E 2.
