    摘要： A display apparatus is provided which, when projecting a video onto a curved surface of an object for display, can realize an undistorted display of the video. The measuring means outputs the distance information representing the distance to the object. Based on the distance information produced by the measuring means, the curved surface contour is detected with high precision. According to at least the detected curved surface contour distortions, pixels of the display image are unevenly rearranged to correct the video information before it is output. This arrangement realizes an undistorted display of video when the video is projected onto the curved surface of the object.

    摘要： A beam light source of an image display device which displays an image on a screen by scanning an optical beam in a two-dimensional direction in which the beam light source includes a light source that emits a diffuse light modulated according to an image signal, and an optical element that shapes the light emitted from the light source to the optical beam. The optical beam has an elliptically shaped beam spot on the screen in which a major axis of the beam spot is substantially perpendicular to a scanning direction. A horizontal spot size of the optical beam on an exit surface of the optical element is at least or equal to a horizontal spot size of the optical beam on the screen, and the horizontal spot size of the optical beam on the screen is no greater than a horizontal pixel pitch displayed on the screen.

    摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.

    摘要： There is provided a safe image display apparatus for projecting an image on a screen that can minimize a stimulus to eyes, retinae and optic nerves from projected light entering into the eyes directly. By comparing a displayed image captured by a camera with an input image signal, a changed area is detected as a difference area and, then, a projected image signal is generated wherein a picture area image signal in the input image signal that corresponds to this difference area is masked by a black signal. The obtained projected image signal is projected onto the screen.
