IMAGE PROCESSING DEVICE, IMAGE PROCESSING DEVICE OPERATION METHOD, AND IMAGE PROCESSING DEVICE OPERATION PROGRAM

To provide an image processing device, an image processing device operation method, and an image processing device operation program, capable of extracting a point representing a track of a target charged particle with higher accuracy.SOLUTION: An acquisition part of an image processing device acquires a track recording image in which a point representing the track of charged particles containing target charged particles has been reflected. A Fourier transform processing part performs the Fourier transform processing on the track recording image acquired in the acquisition part. A band pass filter processing part performs the band pass filter processing on the track recording image after the Fourier transform processing. An inverse Fourier transform processing part performs the inverse Fourier transform processing on the track recording image after the band pass filter processing.SELECTED DRAWING: Figure 12 【課題】対象荷電粒子の飛跡を表す点を、より高精度に抽出することが可能な画像処理装置、画像処理装置の作動方法、画像処理装置の作動プログラムを提供する。【解決手段】画像処理装置の取得部は、対象荷電粒子を含む荷電粒子の飛跡を表す点が映った飛跡記録画像を取得する。フーリエ変換処理部は、取得部において取得した飛跡記録画像に対してフーリエ変換処理を施す。バンドパスフィルタ処理部は、フーリエ変換処理後の飛跡記録画像に対してバンドパスフィルタ処理を施す。逆フーリエ変換処理部は、バンドパスフィルタ処理後の飛跡記録画像に対して逆フーリエ変換処理を施す。【選択図】図１２
