PROBLEM TO BE SOLVED: To make operation sound of a switch disposed in an interior of a vehicle hardly being recognized as noise.SOLUTION: The switch 2 outputs a signal depending on an operation of a user. An image acquisition part 3 acquires an image containing a user's operation. A control part 5 controls a speaker 4 to output sound containing frequency component of suppressing operation sound generated with an operation of a switch 2 based on an image acquired by the image acquisition part 3.SELECTED DRAWING: Figure 1

    【課題】車室内に配置されたスイッチの操作音をノイズとして認識されにくくする。【解決手段】スイッチ2は、ユーザの操作に応じて信号を出力する。画像取得部3は、ユーザの操作を含む画像を取得する。制御部5は、画像取得部3により取得された画像に基づいて、スイッチ2の操作に伴って発生する操作音を抑制する周波数成分を含む音をスピーカー4から出力させる。【選択図】図1
