    Abstract: Provided is a laser projection apparatus which forms each one frame by performing two-dimensional scanning with laser light and projects images on a screen (201) with blanking periods inserted between frames, the laser light having been outputted from a laser light source (110). The laser projection apparatus is provided with a chive controlling device (132) which, in each of the blanking periods, changes the polarization state of the laser light having been outputted from the laser light source. This configuration enables speckle reduction by having the polarization state changed from one frame to another, and also enables favorable image projection since there is no change in luminance within each one of the frames. Thus, it is made possible to obtain image quality more favorable than that obtained conventionally.

    Abstract: A laser projector comprises an oscillation device for displacing at least one of a plurality of optical elements, which constitute the projection optical system of the laser projector, periodically along the direction of the optical axis of laser light. The laser projector reduces the speckle of a projection image on an arbitrary screen to such an extent as it cannot be recognized with human eyes, without having a significant effect on the image resolution, by periodically displacing the position of the smallest spot of laser light projected from the projection optical system. An image projection method is also provided
