ABSTRACT:
An optical scanning device, which scans a plurality of color light components so as to display an image, includes a light source unit that supplies a plurality of light beams, and a scanning unit that repeatedly scans each light beam from the light source unit in a first direction and a second direction in a region to be irradiated. The scanning unit is driven such that a frequency for scanning the light beam in the first direction becomes higher than a frequency for scanning the light beam in the second direction, and such that different light beams of the same color light component are allocated to at least some pixels of the image whenever the light beam is scanned in the second direction in the region to be irradiated.
