Abstract
The purpose of the present invention is to provide a laser scanning display device capable of achieving high-resolution projection display while ensuring that the luminance and the size of the pixels are uniform to maintain the quality of the projection display. The scanning display device is configured to apply noise from a dither noise generator () to a horizontal scanning position on an oscillating mirror () determined by a scanning position determination unit (); normalize the horizontal scanning position to which the noise was applied using a normalizing unit (); acquire a pixel address corresponding to the normalized horizontal scanning position by referring to a pixel address table (); read pixel data corresponding to the pixel address from an image memory (); and modulate laser light by driving a light source () for emitting the laser light.
