Abstract: In a directionality control system, a camera device captures a video of image capture area (SA). A microphone array device collects a sound in image capture area (SA). A signal processing section detects a sound source of the sound in image capture area (SA) which is collected by the microphone array device. In a case where the detected sound source is within a range of privacy area (PRA), an output control section controls the sound in image capture area (SA) which is collected by the microphone array device and is output from speaker device (37).
