According to one embodiment, an input apparatus comprises an input detector, a vibration detector, a controller, and a sensitivity adjustment unit. The input detector detects an input by the blockage of a light beam to scan a scan region. The vibration detector detects a vibration equal to or more than a set sensitivity applied to the input detector. The controller stops the light beam scanning when the input detector detects no inputs for a given length of time. The controller restores the light beam scanning when the vibration detector detects a vibration. The sensitivity adjustment unit changes the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the light beam scanning.
