Abstract:
(EN) The purpose of the present invention is to reduce the erroneous detection of electrode capacitance changes and the like. A capacitance detection device (1) comprises: a voltage measurement unit (11) that measures first voltage values (V1) and/or second voltage values (V2) for a predetermined number of cycles; and a validity determination unit (12) that determines whether a voltage value measured when a capacitance or capacitance change is detected in an electrode (E) is valid or not on the basis of the first voltage values (V1) and/or second voltage values (V2) for the predetermined number of cycles.
(FR) Le but de la présente invention est de réduire la détection erronée de changements de capacité d'électrode et similaires. Un dispositif de détection de capacité (1) comprend : une unité de mesure de tension (11) qui mesure des premières valeurs de tension (V1) et/ ou des secondes valeurs de tension (V2) pour un nombre prédéterminé de cycles; et une unité de détermination de validité (12) qui détermine si une valeur de tension mesurée lorsqu'un changement de capacité ou une capacité est détecté dans une électrode (E) est valide ou non sur la base des premières valeurs de tension (V1) et/ ou des secondes valeurs de tension (V2) pour le nombre prédéterminé de cycles.
(JA) 電極の容量変化等の誤検出を低減する。容量検出装置(1)は、所定回数分の第1電圧値(V1)および第2電圧値(V2)の少なくとも一方を計測する電圧値計測部(11)と、所定回数分の第1電圧値(V1)および第2電圧値(V2)の少なくとも一方に基づいて、電極(E)において容量または容量変化が検出された場合に計測される電圧値が有効であるか否かを判定する有効判定部(12)と、を備える。
