Abstract
A projector and an apparatus and method for driving an optical scanner are disclosed. A sensing signal processor receives a sensing signal that represents sensing of operation of the optical scanner and generates a horizontal scan signal corresponding to a horizontal frequency of the optical scanner on the basis of the received sensing signal. A driving signal generator generates at least one of a horizontal reference signal including line information that indicates the number of horizontal lines of a horizontal driving signal of the optical scanner, a reference clock signal and a scanner driving signal for driving the optical scanner on the basis of the generated horizontal scan signal.
