Abstract
An image drawing device includes a laser light source controller controlling a laser light output timing of a laser light source unit and an output value of laser light so that a drawing image based on input image data is generated in a scanning region; a scanner controller controlling scanning so that the laser light is scanned with an amplitude; and a characteristic detection controller controlling the scanner controller to scan in a range in which an amplitude of scanning exceeds a scanning range corresponding to an amplitude when the laser light output value is adjusted, control the laser light source controller to output characteristic detection laser light during scanning outside of a range in which the drawing image is generated and beyond the amplitude of the scanning range, and adjust the output value of the laser light based on a detected output value of the characteristic detection laser light.
