Abstract
An image display device includes: an RGB laser diode configured to output laser light; a horizontal scanner configured to reflect the laser light and perform a reciprocating operation in a horizontal direction; a scanning detection unit configured to detect a forward or reverse operation range and a reciprocating operation range in each line in the horizontal direction; a drawing position control unit configured to determine an image display position in each line based on a difference between the detected operation ranges and a reference value; and a laser driver configured to drive the RGB laser diode based on image data at a timing corresponding to the determined image display position.
