The present invention generally relates to a dynamic aperture for controlling the intensity of light of projection lens, more particularly to a dynamic aperture driving apparatus and method for reducing vibration by which vibrations are minimized in spite of command for sudden location change. The dynamic aperture driving apparatus comprises rotating means, driving means, sensing means and driving control means, whereas a location control signal is characterized by minimizing vibration when the rotating means arrives at a commanded location by an increase in rising time and/or falling time of a target location signal through an RC integral circuit within the driving control means. |
