Abstract: A pressing operation detection device includes a pressing operation determination unit determining whether a pressing operation has been performed based on a touch on an operation unit and a pressing amount, an increase-and-decrease frequency detection unit detecting occurrence frequency of increase and decrease of a pressing amount every predetermined period of time, and a determination controller changing content of the determination process of the pressing operation determination unit based on the occurrence frequency detected while a touch on the operation unit is not detected. When a pressing amount is detected although the operation unit is not touched, assuming that increase and decrease of the pressing amount is caused by vibration, content of the determination process is changed such that influence of the vibration is reduced so that detection of a pressing operation which brings a feeling of strangeness to the user which is caused by the vibration may be avoided.

Abstract: In determining a definitive value, if a measured value detected at one timing changes by an amount less than a reference amount from a definitive value generated at a timing one cycle before the one timing, a definitive-value determination unit of a press detection apparatus determines the measured value detected at the one timing as a definitive value at the one timing, and if the measured value detected at the one timing has changed by an amount equal to or more than the reference amount from the definitive value at the preceding timing, the definitive-value determination unit determines a value obtained by adding the reference amount to the definitive value at the preceding timing as a definitive value at the one timing. This allows a value in which the influence of vibration is limited to be used in a determination of a pressing operation.
