Abstract
According to one embodiment, a piezoelectric device drive method includes measuring gains including a first gain by applying voltages including a first voltage to a piezoelectric device at a first timing, calculating gain characteristics associated with the applied voltages from the measured gains, measuring a second gain by applying the first voltage to the piezoelectric device at a second timing, correcting the calculated gain characteristics based on the first gain and the second gain, and calculating a third gain based on the corrected gain characteristics and the second gain in a case where a second voltage other than the first voltage is applied.
