INPUT DEVICE, CONTROL DEVICE, CONTROL SYSTEM, CONTROL METHOD, AND HAND-HELD DEVICE

摘要

[PROBLEMS] To provide an input device, a control device, a control system, and a control method which can correct an output signal of a camera-shaken input to an input device if any without causing a user to feel a phase delay. [MEANS FOR SOLVING PROBLEMS] An input device (1) includes a speed calculation unit (29), a filter (27), a control unit (28), and a memory (26). The speed calculation unit (29) calculates a speed value of a case (10) in the X'-axis direction and Y'-axis direction according to a physical amount outputted from the sensor unit (17) such as an acceleration value in the X'-axis direction and Y'-axis direction which have been outputted from an acceleration sensor unit (16). A filter (27) attenuates the speed value of the signal in the predetermined frequency range among the speed values calculated by the speed calculation unit (29) by a predetermined gain. Since the speed value in the camera-shake frequency range is dynamically attenuated by the filter (27) according to the speed value, a pointer (2) can perform an accurate pointing operation.
