Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical scanning device that can improve the scanning accuracy of an optical scanner.SOLUTION: An image projection device (optical scanning device) 100 includes an optical scanner 10 having two horizontal resonance modes in a horizontal direction, and a drive unit for driving the optical scanner 10. The drive unit selects one of the two resonance modes, and drives the optical scanner 10 in a horizontal direction using the selected resonance mode.
