Abstract:
1. A device for displaying an image, comprising: a first light source for emitting first light; a second light source for emitting second light, a color of said first light differing from a color of said second light; a mirror for reflecting said first light and said second light; an actuator configured to drive said mirror in a scan direction; a photoreceptor for receiving said first light and said second light, said photoreceptor including a first light-receiving region and a second light-receiving region, and a boundary between said first light-receiving region and said second light-receiving region being orthogonal to said scan direction; a controller configured to control light emission and shut off of said first light source, and light emission and shut off of said second light source; a detector configured to detect a deviation between an optic axis of said first light source and an optic axis of said second light source, based on a timing at which said first light is received in said second light-receiving region and a timing at which said second light is received in said second light-receiving region; and a corrector configured to correct a light emission timing of said second light source based on the deviation detected by said detector.
