To provide a technique capable of improving an accuracy of detection.SOLUTION: A video display apparatus 1 includes: an operation detection apparatus 2 that detects an operation including contact by an operation object 7 including a finger of a user to an operation surface 4 set in association with a display surface 3; a camera 5 that is an optical sensor for detecting an image by the operation object 7 on the operation surface 4; and a microphone 6 that is a non-optical sensor for detecting sound or vibration caused by contacting the operation object 7 on the operation surface 4. The operation detection apparatus 2 detects a state including contact or non-contact by the operation object 7 to the operation surface 4 using first detection information of the optical sensor and second detection information of the non-optical sensor, and outputs detection data. When detecting a state in which the operation surface 4 and the operation object 7 contact from the first detection information, and the sound or the vibration corresponding to the state of contacting from the second detection information, the operation detection apparatus 2 determines that it is in the contact state generally.SELECTED DRAWING: Figure 1 【課題】検出の精度を向上できる技術を提供する。【解決手段】映像表示装置１は、表示面３に対応付けて設定された操作面４に対するユーザの手指を含む操作物７による接触を含む操作を検出する操作検出装置２と、操作面４上の操作物７による像を検出する光学センサであるカメラ５と、操作面４での操作物７の接触によって生じる音または振動を検出する非光学センサであるマイク６とを備える。操作検出装置２は、光学センサの第１検出情報および非光学センサの第２検出情報を用いて、操作面４に対する操作物７による接触または非接触を含む状態を検出し、検出データを出力する。操作検出装置２は、第１検出情報から操作面４と操作物７との接触有りの状態を検出し、かつ、第２検出情報から接触有りの状態に対応する音または振動を検出した場合に、総合的に接触状態であると判定する。【選択図】図１
