Abstract
A method performed by a sensor controller detects coordinates of a pen including one or more electrodes that transmit a signal. The method includes a first scanning step of performing an operation of detecting a signal transmitted from an electrode in contact with a panel surface at each of three or more first reference positions at which signal levels can be detected, from the signal detected in a sensor electrode group included in a first range, among plural juxtaposed reference positions. The method includes a second scanning step of performing an operation of detecting a signal transmitted from an electrode not in contact with the panel surface at each of three or more second reference positions at which signal levels can be detected, from the signal detected in a sensor electrode group included in a second range greater than the first range, among the plural reference positions.
