Abstract
A projector includes a screen having a periodic array of color stripes for producing visible light depending on incident light, a light source that remits a light beam, a projection unit that scans an area of the screen where the color stripes are disposed, with the light beam in a direction across the color stripes, to display an image on the screen, a detector that detects the visible light from each of the color stripes as a feedback light pulse, and a controller that adjusts a start-of-emission timing of the light source based on a start-of-detection timing at which the feedback light pulse is detected by the detector and a detection period during which the feedback light pulse is detected by the detector, and controlling the light source to emit the light beam in order to apply light pulses to the color stripes within boundaries thereof.
