INPUT DEVICE AND METHOD OF OPERATING INPUT DEVICE
First Claim
1. An input device for detecting an operation of an operating object, the input device comprising:
- an operating unit on which the operating object performs the operation, the operation including at least one of touching and approaching of the operating objects;
a measurement unit configured to measure a physical quantity corresponding the operation of the operating object onto the operating unit;
a determination unit configured to determine if the operating unit is in an operation ongoing state or a no-operation state, based on at least the physical quantity and a base value; and
a base value updating unit configured to update the base value using the physical quantity during an operation ongoing period in which the operating unit is in the ongoing operation state, if a magnitude of a change in the measured physical quantity per predetermined time period is within a predetermined range.

Abstract
An input device includes a measurement unit configured to measure a physical quantity according to an operation including at least one of touch of an operating object and proximity of the operating object, a determination unit configured to determine an operation state including an operation existence state and an operation nonexistence state, on the basis of at least a base value and the physical quantity, and a base value updating unit configured to update the base value using the physical quantity when a magnitude of a change in the physical quantity per predetermined time falls within a predetermined range, during an operation existence period in which the operation state is the operation existence state.

10. A method of operating an input device for detecting an operation of an operating object, the operation including at least one of touching and approaching of the operating object onto an operation unit of the input device, the method comprising the steps of:
-
measuring a physical quantity corresponding to the operation of the operating object onto the operating unit; determining if the operating unit is in an operation ongoing state or a no-operation state based on at least the physical quantity and a base value; and updating the base value using the physical quantity during an operation ongoing period in which the operating unit is in the ongoing operation state, if a magnitude of a change in the measured physical quantity per predetermined time period is within a predetermined range.
