Electronic apparatus
First Claim
1. An electronic apparatus comprising:
- an operation unit;
an operation detection unit detecting an operation to the operation unit and switchable between an operation enable state (ON state) and an operation disable state (OFF state);
a calibration unit for performing calibration on the operation detection unit; and
a control unit for setting the operation detection unit to the operation enable state and controlling the calibration unit to perform calibration on the operation detection unit according to a first request,wherein the operation detection unit can correctly detect an operation to the operation unit when the setting to the operation enable state by the control unit and the calibration by the calibration unit are performed according to the first request in the operation disable state, andthe control unit suppresses the setting to the operation enable state of the operation detection unit and the calibration by the calibration unit according to the first request performed during setting the operation detection unit to the operation disable state from the operation enable state.

Abstract
A touch sensor becomes an operation enable state in which an operation state can be detected, when predetermined voltage is applied. A touch sensor control unit switches the touch sensor to an operation detection enable state by raising the voltage to a predetermined voltage level gradually and performing predetermined calibration when detecting an activation permission request of the touch sensor in a no-voltage applied state of the touch sensor, and switches the touch sensor to an operation detection disable state in which an operation state of the touch sensor cannot be detected by lowering voltage gradually to the no-voltage applied state. And, when detecting the activation permission request of the touch sensor during switching to the operation detection disable state, the touch sensor control unit switches the touch sensor to the operation detection enable state, after the switching operation to the operation detection disable state is completed.
