Abstract
(EN)
The purpose of the present embodiment is to provide a sensor device with which it is possible to perform sensing with high accuracy.  The sensor device of the present embodiment comprises a capacitance-type touch panel, a knob provided so as to be capable of rotating around a rotating shaft, a conductor held in the knob and facing the touch panel in a portion of the circumference centering around the rotating shaft, and a sensor controller for controlling the touch panel. The sensor controller holds a reference signal that corresponds to capacitance while the conductor is not facing the touch panel, and detects the first coordinate of the conductor in a first sensing period on the basis of the reference signal and a first sensor signal received from the touch panel while the conductor faces a first position of the touch panel.

L'objectif de la présente invention est de fournir un dispositif capteur au moyen duquel il est possible d'effectuer une détection d'une grande précision. Le dispositif capteur du présent mode de réalisation comprend un écran tactile de type capacitif, un bouton disposé de façon à pouvoir tourner autour d'un arbre rotatif, un conducteur maintenu dans le bouton et faisant face à l'écran tactile dans une partie de la circonférence centrée autour de l'arbre rotatif, et un dispositif de commande de capteur pour commander l'écran tactile. Le dispositif de commande de capteur maintient un signal de référence qui correspond à la capacité tandis que le conducteur ne fait pas face à l'écran tactile, et détecte la première coordonnée du conducteur dans une première période de détection sur la base du signal de référence et d'un premier signal de capteur reçu en provenance de l'écran tactile tandis que le conducteur fait face à une première position de l'écran tactile.
