Claim 0:
1. A touch detecting apparatus, comprising:
an electrostatic sensor provided on an object; and
a processor configured to:
detect whether a hand touches the object based on a capacitance measured by the electrostatic sensor,
in response to the capacitance being greater than or equal to a first touch threshold, detect that a hand touches the object, and
when a change amount of the capacitance during a first predetermined time becomes greater than or equal to a noise threshold, continue, for a second predetermined time, a state where a correction value has been added to the first touch threshold,
wherein
the processor is further configured to
in response to the change amount of the capacitance during the first predetermined time becoming greater than or equal to the noise threshold, start counting time by a first timer, and
in response to the change amount of the capacitance during the first predetermined time becoming smaller than the noise threshold and the time counted by the first timer exceeding the second predetermined time, end continuing a state where the correction value has been added to the first touch threshold.
