A captured image obtaining unit 50 of an output control device 10 obtains a captured image such as a polarization image from an imaging device 12. A space information obtaining unit 54 obtains a normal line and a position of a surface of an actual object in a space and a sound absorption coefficient at the surface. A correction coefficient obtaining unit 56 calculates energy of sound reaching a listener including sound reflected at the actual object and obtains a correction coefficient to be given to a level of a sound signal on the basis of the sound energy. An output unit 60 adjusts the sound signals by using the correction coefficient 62 and outputs the adjusted sound signals to speakers 16a and 16b.
