To provide an image prediction device capable of predicting a sound image position with high accuracy, and provide a sound image prediction method.SOLUTION: A sound image prediction device according to an aspect of an embodiment, comprises a control part. The control part acquires an acoustic signal output into a vehicle by a plurality of sensors, and calculates difference information containing a level difference and a phase difference in the acoustic signal on the basis of the acoustic signal of each of the plurality of acquired sensors. The control part previously generates normal relationship information indicating a relation of the difference information on the basis of the acoustic signal and the sound image position in the acoustic signal, and predicts the sound image position in the acoustic signal on the basis of the normal relation information and the difference information calculated. The control part executes a correction processing for correcting the predicted sound image position on the basis of sound noise information related to sound noise in the vehicle.SELECTED DRAWING: Figure 1

    【課題】音像位置を精度良く予測することができる音像予測装置および音像予測方法を提供することを目的とする。【解決手段】実施形態の一態様に係る音像予測装置においては、制御部を備える。制御部は、車内に出力された音響信号を複数のセンサによって取得し、取得した複数のセンサそれぞれの音響信号に基づいて音響信号におけるレベル差および位相差を含む差分情報を算出する。制御部は、音響信号に基づく差分情報および音響信号における音像位置の関係性を示す定位関係情報を予め生成しておき、当該定位関係情報と、算出した差分情報との照合結果に基づいて音響信号における音像位置を予測する。制御部は、予測した音像位置を、車内における騒音に関する騒音情報に基づいて補正する補正処理を実行する。【選択図】図1
