    摘要: A reliable image display apparatus is provided that is capable of preventing a direct current from being applied to liquid crystal of a spatial light modulating element so that damage such as burns in the liquid crystal and screen flicker may be prevented and a high resolution image with high image quality may be displayed. The image display apparatus is configured to divide a frame into 2i sub frames (i corresponding to a natural number) and sequentially display the sub frames using the liquid crystal spatial light modulating element. The image display apparatus includes a polarity switching unit configured to reverse the polarity of a drive voltage for a pixel of the spatial light modulating element for every j sub frame(s) (j corresponding to a natural number that is less than 2i) and for every n frame(s)(n corresponding to a natural number).

    摘要: An apparatus, method, system, computer program and product, each capable of converting a resolution of an image using an interpolation method. The interpolation method determines a pixel value of an interpolated pixel based on a weighting factor, which is generated based on a pixel value and a distance value of a reference pixel.

    摘要: An illumination system having a light-emitting unit and a reflecting mirror for condensing light is described. The illumination system includes a lens plate having a plurality of approximately identical lens elements. The lens plate is disposed away from the light-emitting unit and the plurality of lens elements are arranged two-dimensionally and approximately perpendicular to a main optical axis of a projection lens system and an object to be projected. The illumination system further includes first and second lenticules, and at least one convex lens disposed so as to refract a light path of the light flux formed by each of the plurality of lens elements such that the light flux illuminates a surface of the object to be projected after passing through the first and second lenticules.
