A sound image control apparatus and sound image control method capable of increasing the accuracy, in particular, in the distance direction while keeping fixed intervals of transmission characteristic filters, without increasing the number of the transmission characteristic filters. Sound image control apparatus (100) is provided with distance gain control section (101) that performs gain control of the sound pressure of an input monaural audio signal of one channel in the distance direction from a head to a sound image before input to virtual sound field 1 sound image localization section (120) and virtual sound field 2 sound image localization section (130), and reflected sound gain control section (102) that performs gain control by distance of a reflected sound of the sound pressure of the input monaural audio signal of one channel before input to virtual reflected sound generating section (150) that controls the sound image to be localized outside the head when the sound is listened to with headphones.
