Abstract
An optical scanning control device includes a scanner that scans light emitted from a laser in accordance with an image signal to form an image on a screen; a first optical detector that detects light scanned by the scanner; a second optical detector that detects light scanned by the scanner; and a controller that controls a deflection angle of the scanner based on a time difference between an output of the first optical detector and an output of the second optical detector.
