<p>Provided are: a capacitive touch sensor device preventing erroneous touch-off determinations; and an electronic apparatus including the touch sensor device. The touch sensor device includes: a touch panel on which a capacitance is formed with a pointer; a signal calculation means calculating a signal output value based on a magnitude of the capacitance; a contact determination means comparing the signal output value with a threshold and determining whether the pointer has been brought into contact with or separated from the touch panel; and a threshold calculation means updating a first threshold used for determining whether the pointer has been brought into contact with the touch panel, if an increase of the signal output value is detected during a first unit time within a time period from a determination that the pointer has been brought into contact with the touch panel until a determination that the pointer has been separated from the touch panel.</p> |
