Abstract
(EN) In the present invention, a sample extraction unit (20) acquires a sample data sequence of a signal indicating the touch state quantity detected at a touch panel. A discrete Fourier transform unit (40) transforms the sample data sequence into frequency regions. A frequency spectral analysis unit (50) determines a frequency spectrum distribution on the basis of the sample data transformed into frequency regions. A peak detection unit (60) detects the peak within a pulse frequency band in a frequency spectrum distribution, and determines the pulse by taking the reciprocal of the frequency of the detected peak.
(FR) Selon la présente invention, une unité d'extraction d'échantillon (20) acquiert une séquence de données d'échantillon d'un signal indiquant l'importance de l'état tactile détectée au niveau d'un écran tactile. Une unité de transformée de Fourier discrète (40) transforme la séquence de données d'échantillon en régions de fréquences. Une unité d'analyse spectrale de fréquences (50) détermine une distribution du spectre de fréquences sur la base des données d'échantillon transformées en régions de fréquences. Une unité de détection de crête (60) détecte la crête dans une bande de fréquence d'impulsion lors d'une distribution du spectre de fréquences, et elle détermine l'impulsion par prise en compte de la réciproque de la fréquence de la crête détectée.
