A laser projector 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 second light differing from a color of said first light; a mirror for reflecting said first light and said second light; an actuator (130, 132) configured to drive said mirror in a scan direction; and a controller configured to control light emission of said first light source, and light emission of said second light source; characterized by a second mirror configured to allow a part of said first light and a part of said second light reflected by said mirror to pass therethrough, and reflect another part of said first light and another part of said second light, and project onto a screen said part of said first light and said part of said second light that have passed through said second mirror as said image; a photoreceptor adapted to receive said first light reflected by said second mirror and said second light reflected by said second mirror, said photoreceptor including a first light-receiving region (210, 240) and a second light-receiving region (220, 230), and a boundary between said first light-receiving region and said second light-receiving region being orthogonal to said scan direction; 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 first light-receiving region (210, 240), a timing at which said first light is received in said second light-receiving region (220, 230) and a timing at which said second light is received in said second light-receiving region (220, 230); and a corrector configured to correct a light emission timing of said second light source based on the deviation detected by said detector. a first light source for emitting first light; a second light source for emitting second light, a color of said second light differing from a color of said first light; a mirror for reflecting said first light and said second light; an actuator (130, 132) configured to drive said mirror in a scan direction; and a controller configured to control light emission of said first light source, and light emission of said second light source; characterized by a second mirror configured to allow a part of said first light and a part of said second light reflected by said mirror to pass therethrough, and reflect another part of said first light and another part of said second light, and project onto a screen said part of said first light and said part of said second light that have passed through said second mirror as said image; a photoreceptor adapted to receive said first light reflected by said second mirror and said second light reflected by said second mirror, said photoreceptor including a first light-receiving region (210, 240) and a second light-receiving region (220, 230), and a boundary between said first light-receiving region and said second light-receiving region being orthogonal to said scan direction; 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 first light-receiving region (210, 240), a timing at which said first light is received in said second light-receiving region (220, 230) and a timing at which said second light is received in said second light-receiving region (220, 230); and a corrector configured to correct a light emission timing of said second light source based on the deviation detected by said detector.
