PROBLEM TO BE SOLVED: To display or pick up an excellent image in an optical scanning device. An optical scanning device (1) includes a light guide path that guides incident light to emit outgoing light from an outgoing end, a vibrating unit that vibrates the outgoing end so that the outgoing light repeatedly draws a predetermined scanning locus, and an exit unit. A light emission control unit 22 that controls the emission of emitted light, a photodetector that detects a part of the emitted light, a scanning coordinate generation unit that generates scanning coordinates related to a predetermined trajectory, and a vibration unit that corresponds to the scanning coordinates. A drive signal generation unit 20 that generates a sine wave whose amplitude is modulated as a drive signal for driving, and a coordinate calculation unit that calculates image coordinates using scanning coordinates and outputs the image coordinates as image coordinates. At least one of the radius of the image coordinates and the declination of the image coordinates depends on the radius of the scanning coordinates and the declination of the scanning coordinates.
