摘要： An optical scanning device, a driving method of an optical scanning device, and an image drawing system that can suppress a decrease in image quality of a drawn image are obtained.
A driving controller provides a first driving signal having a first driving frequency to a first actuator, provides a second driving signal having a second driving frequency to a second actuator, derives a first average phase delay time by averaging a first phase delay time of an output signal of a first angle detection sensor with respect to the first driving signal in a plurality of cycles, derives a second average phase delay time by averaging a second phase delay time of an output signal of a second angle detection sensor with respect to the second driving signal in a plurality of cycles, generates a first reference signal based on the first driving signal and the first average phase delay time, and generates a second reference signal based on the second driving signal and the second average phase delay time.
