Driving control is performed by supplying a Z scanner with a driving signal processed by an adjustment function. The adjustment function adjusts the driving signal by using a simulated transfer function that simulates an actual transfer function indicative of an actual frequency characteristic of the Z scanner so that executing processing of the simulated transfer function on the adjusted driving results in decrease of vibration of an output signal from the simulated transfer function. The adjustment function processing is configured so as to execute processing of the simulated transfer function G(s) on the driving signal, to execute processing of an inverse target transfer function K(s) corresponding to the inverse of the target transfer function on an output from the G(s), to determine the difference between the driving signal and the output of K(s), to apply a gain g to the difference, and to add the signal after the gain is applied to the driving signal. Therefore, the output from the G(s) approximates to the target transfer function which is the inverse of the K(s).
