ABSTRACT:
An image display apparatus includes first and second actuators that cause a mirror (movable part) to oscillate about first and second axes intersecting with each other. The first actuator is driven based on a drive signal having a frequency component around a resonant frequency relevant to oscillatory motion of the mirror, to cause the mirror to oscillate about the first axis, thereby scanning a light beam reflected off the mirror in a horizontal direction of the raster scanning. The drive signal is generated by regulating a reference drive signal based on a correction signal for use in correcting distortion of a displayed image, the distortion occurring when the first actuator is driven based on the reference drive signal for use as the drive signal to cause oscillatory motion of the mirror. This consequently simplifies distortion correction in the horizontal direction (the main scanning direction).
