Abstract
A sensor controller that controls a touch sensor detects a position of a passive pointer. The sensor controller includes a transmission circuit that transmits a transmission signal to the touch sensor in a plurality of third periods, each including a first period for measuring electromagnetic noise and a second period for detecting the position of the passive pointer and a processor configured to measure a level of electromagnetic noise at a frequency associated with the first period and a frequency associated with the second period, and select, as a scan frequency of the transmission signal in the second period, the frequency associated with the first period or the frequency associated with the second period according to a measurement result of the level of the electromagnetic noise at the frequency associated with the first period and the level of the electromagnetic noise at the frequency associated with the second period.
