"textContent": "A capacitance sensor includes a switch control unit that performs a first switching process that turns on a first switch and then repeatedly performs a second switching process that complementarily switches off and on second and third switches that are respectively connected to second and third capacitors; an obtaining unit that calculates, as a sensor output value, a number of times the second switching process is repeated until a magnitude relationship reverses between an intermediate potential and a reference potential; a calculation unit that calculates a sensor output corrected value obtained by correcting the sensor output value such that a resolution becomes uniform; and a determination unit that determines whether a detection target exists from a magnitude relationship between a sensor output difference value and a determination threshold value.",
