Abstract
Provided is a sensor controller connected to a capacitive touch sensor. The sensor controller includes a scan execution circuit which, in operation, repeatedly performs a first scan and a second scan on the capacitive touch sensor in a time-division manner, a first calculation circuit which, in operation, calculates a first pen position from a first detection signal acquired through the first scan performed by the scan execution circuit, a second calculation circuit which, in operation, calculates a touch position and a second pen position from a second detection signal acquired through the second scan performed by the scan execution circuit, and an output processing circuit which, in operation, outputs a pen position that differs depending on a result of a comparison process in which the first pen position calculated by the first calculation circuit is compared with the second pen position calculated by the second calculation circuit.
