1. An electronic device comprising:
- a capacitive touch sensor including a sensor area;
a processor configured to perform, upon detection by the capacitive touch sensor of a first capacitance greater than or equal to a first capacitance amount threshold, processing corresponding to a touched position; and
a controller configured to perform control to restrict the processing corresponding to the touched position in a case where a certain condition is satisfied even when the capacitive touch sensor detects the first capacitance greater than or equal to the first capacitance amount threshold, the certain condition including a second capacitance greater than or equal to a second capacitance amount threshold being detected in an edge area of the sensor area of the capacitive touch sensor, the second capacitance amount threshold being less than the first capacitance amount threshold.

Abstract
A touch sensor driver circuit drives a capacitive touch sensor to detect the presence of an operation performed with a conductive member and detects a position of the operation. A controller performs processing corresponding to the operation on the touch sensor with the conductive member. In a case where detection of a capacitance greater than or equal to a threshold in an edge area of a sensor area of the capacitive touch sensor and a touch operation in a central area that is the sensor area excluding the edge area occur at the same time, the controller ignores the touch operation.
