An image display apparatus employing a laser beam source includes: a light modulating unit that modulates a laser beam emitted from the laser beam source into image light representing an image; and a driving-signal generating unit that generates, on the basis of an image signal of a frame image updated at a fixed first period, a driving signal for driving the light modulating unit. The driving-signal generating unit periodically inserts a noise image in the driving signal while maintaining timing for updating display of the frame image at the first period.
