A directivity control system (10, 10A) comprising: at least one imaging part (11-1n, 11A-1 nA) adapted to capture an image; a sound collection part adapted to collect sounds; a display part adapted to display to a user image data captured by the at least one imaging part (11-1n, 11A-1nA); a directive direction calculation part adapted to calculate a coordinate indicating a direction towards a sound position corresponding to a position of the image designated by said user on said display part, a control part (35, 35A) adapted to form a directivity in the sounds collected by the sound collection part in the calculated directive direction, characterised in that, when it is determined that the sound position is included in a preset privacy protection region, the control part (35, 35A) is adapted - to control output of the sounds collected by the sound collection part by performing a mute process, a masking process, or a voice change process on sound data of the sounds collected by the sound collection part, or - to control output of the sounds which are collected by the sound collection part and of which the directivity is formed by performing a mute process, a masking process, or a voice change process on sound data of the sounds which are collected by the sound collection part and of which the directivity is formed, or - to suspend the collection of sounds in the sound collection part. at least one imaging part (11-1n, 11A-1 nA) adapted to capture an image; a sound collection part adapted to collect sounds; a display part adapted to display to a user image data captured by the at least one imaging part (11-1n, 11A-1nA); a directive direction calculation part adapted to calculate a coordinate indicating a direction towards a sound position corresponding to a position of the image designated by said user on said display part, a control part (35, 35A) adapted to form a directivity in the sounds collected by the sound collection part in the calculated directive direction, characterised in that, when it is determined that the sound position is included in a preset privacy protection region, the control part (35, 35A) is adapted - to control output of the sounds collected by the sound collection part by performing a mute process, a masking process, or a voice change process on sound data of the sounds collected by the sound collection part, or - to control output of the sounds which are collected by the sound collection part and of which the directivity is formed by performing a mute process, a masking process, or a voice change process on sound data of the sounds which are collected by the sound collection part and of which the directivity is formed, or - to suspend the collection of sounds in the sound collection part. - to control output of the sounds collected by the sound collection part by performing a mute process, a masking process, or a voice change process on sound data of the sounds collected by the sound collection part, or - to control output of the sounds which are collected by the sound collection part and of which the directivity is formed by performing a mute process, a masking process, or a voice change process on sound data of the sounds which are collected by the sound collection part and of which the directivity is formed, or - to suspend the collection of sounds in the sound collection part.
