Abstract: Provided is a three-dimensional (3D) image display apparatus using laser beam scanning (LBS) projection optical systems. The 3D image display apparatus includes a plurality of LBS projection optical systems arrayed in horizontal and vertical directions, an input unit through which a 3D image signal is input, and an image signal controller configured to distribute the 3D image signal input through the input unit to the LBS projection optical systems. Each of the arrayed LBS projection optical systems has a beam-projection center point for outputting light to an outside of the LBS projection optical system, and an image projected from the beam-projection center point is a horizontal-parallax image based on the beam-projection center point.

Abstract: An image generator is provided which obtains a specular image and a diffuse image from an image acquired by a polarized light field camera by separating two reflection components of a subject, and a control method thereof. The image generator may include a main lens, a polarizing filter part, a photosensor, a microlens array, and a controller that generates a single image in response to the electrical image signal and extracts, from the generated image, a specular image and a diffuse image that exhibit different reflection characteristics of the subject.
