Abstract
A reproduction device, contains a rotatable operation disk part for performing an input related to reading of data stored in a memory and a capacitance sensor section for outputting a sensor value expressing a change of a capacitance according to depression of the rotatable operation disk part. The device also contains a storage part for storing a reference value corresponding to the sensor value obtained while the rotatable operation disk part is not depressed, and a control part for judging presence/absence of pressing on the rotatable operation disk part based on a vector quantity being a relative value obtained from a difference between the sensor value output from the capacitance sensor section and the reference value stored in the storage part.
Claims12
A reproduction device, comprising:
- a rotatable operation disk part for performing an input related to reading of data stored in a memory;
- a capacitance sensor section for outputting a sensor value expressing a change of a capacitance according to depression of the rotatable operation disk part;
- a storage part for storing a reference value corresponding to the sensor value obtained while the rotatable operation disk part is not depressed;
- and
- a control part for judging presence/absence of pressing on the rotatable operation disk part based on a vector quantity being a relative value obtained from a difference between the sensor value output from the capacitance sensor section and the reference value stored in the storage part.
A reproduction method performed by using a controller comprising a rotatable operation disk part for performing an input related to reading of data stored in a memory, the reproduction method comprising the steps of:
- acquiring a sensor value expressing a change of a capacitance according to depression of the rotatable operation disk part;
- calculating a vector quantity being a relative value obtained from a difference between a reference value corresponding to the sensor value obtained while the rotatable operation disk part is not depressed and the acquired sensor value;
- and
- judging presence/absence of pressing on the rotatable operation disk part based on the calculated relative value.
