In this paper, we propose a novel sound field reproduction system that combines an image sensor and a wavefront synthesis method. This system employs the spectral division method using a spatial localization filter and performs listener detection via image sensing, which enables us to reproduce the sound field at a specific listener's position with high accuracy. A simulation experiment and subjective assessments of directional perception and sound quality perception show the proposed method's superiority in terms of directional perception.
