Abstract:
An image projector according to the present invention includes a light source for emitting a laser beam, of which the intensity has been modulated in accordance with a modulation signal representing an image to be projected, and a beam deflection section for deflecting the laser beam two-dimensionally such that the image is produced by repeatedly scanning a screen with the laser beam in a predetermined pattern. The predetermined pattern has a repetitive frequency that is lower than a frame rate of the image.
