Abstract: A contact determination device includes a sensor measuring a contact degree of a body to be detected with an object, a contact determination unit determining whether the body to be detected is in contact with the object, based on a reference value, and a correction unit correcting the reference value, in which a cumulative value is obtained by accumulating a fluctuation amount of the detection value from a contact start time of the body to be detected with the object during a period in which the body to be detected is in contact with the object, and when the detection value increases as the contact degree increases, the correction unit corrects the reference value, based on a maximum value of the cumulative value, or when the detection value decreases as the contact degree increases, the correction unit corrects the reference value, based on a minimum value of the cumulative value.

Abstract: An electrostatic input apparatus is provided. A measuring unit measures capacitance at a plurality of coordinates of an electrostatic coordinate input unit. A converting unit obtains a reference value of the capacitance and converts the capacitance to difference values according to a distance between the electrostatic coordinate input unit at the coordinates and a finger. A first coordinate calculating unit calculates barycentric coordinates of a contact portion from the difference values for the plurality of coordinates. A cycle determining unit determines whether the difference values at coordinates on a circumference of a circle with a predetermined radius centered on the barycentric coordinates exhibit periodicity of two cycles in one round along the circle. An operation determining unit performs, when the cycle determining unit determines that the difference values exhibit periodicity of two cycles, a determination that an input operation using two or more fingers has been performed.

Abstract: An input apparatus includes a plurality of electrodes spaced apart from each other, a signal processing unit configured to output an input signal depending on a change in a capacitance of each electrode, and a determination unit configured to determine whether an operation object comes in a proximity of at least one of electrodes based on input signals output from the signal processing unit. The determination unit makes a determination such that in a case where one of the input signals is greater than or equal to a first threshold value and an integral value of another of the plurality of input signals in a predetermined integration period is greater than or equal to a second threshold value, it is determined that an operation object has come in a proximity of an electrode corresponding to the one of the input signals.

Abstract: A boundary position, which determines the range of the positions of the window within which trap prevention control is disabled, is set according to the sum of a first amount of rotation and a second amount of rotation. The first amount of rotation approximates a change, in a reference amount of rotation, that corresponds to a change in a detected voltage from a reference voltage. The second amount of rotation is set to a value that is smaller than the difference between a specific amount of rotation at a stop and the reference amount of rotation and is larger than the amount of variations in the reference amount of rotation.
