Abstract:
A laser pointer may include a laser light emitter that emits a laser beam, a housing accommodating the laser light emitter; a vibration detection sensor that detects a vibration produced in the housing, a shake correction mechanism that changes a direction of the laser beam emitted by the laser light emitter, and a controller that controls the direction of the laser beam, which is changed by the shake correction mechanism, into a direction so as to offset the vibration detected by the vibration detection sensor. The controller may be configured to calculate a frequency of the vibration; calculate a movement amount of the vibration; determine whether a vibration applied to the housing is caused by a hand-shake based on the frequency of the vibration and the movement amount of the vibration; and activate the shake correction mechanism in response to a determination that the vibration is caused by a hand-shake.
