Abstract
An operation input detection device includes an operation input section, a capacitive sensor, an operation input detecting section, and a sensor calibration section, which executes calibration of the capacitive sensor. The sensor calibration section includes an irregular calibration section. The irregular calibration section executes the calibration if the sensor output that has changed in the same direction as when the object to be detected approaches the operation input section exceeds a first threshold value, and the sensor output subsequently changes in the opposite direction and exceeds a second threshold value set in the opposite direction within a predetermined time.
