    • In an illumination optical system and a liquid crystal projector apparatus using the same, two lens arrays each comprising linear convex lens arrays with their pitches shifted from each other are used for improving image quality such as not to generate shadows of the cementing ridge of a cross dichroic prism, and a polarization-converting optical system is appropriately disposed, so as to obtain uniform illumination effects efficiently. The vertical angle ridge 71 of four prisms constituting the cross dichroic prism 70 is disposed so as to be orthogonal to the optical axis, the polarization-converting optical system 3 is disposed such that a plane including the vertical angle ridge 71 and optical axis and the direction along which stripes of half-wavelength phase films 32 extend are orthogonal to each other, and the direction of shifting the lens columns of a plurality of linear convex lens arrays constituting the first and second lens arrays 21 and 22 is orthogonal to the plane.
    • 在照明光学系统和使用该照明光学系统的液晶投影仪装置中,使用两个透镜阵列,每个透镜阵列都具有彼此间距偏移的线性凸透镜阵列,以提高图像质量,例如不产生交叉的固井脊的阴影 二向色棱镜和偏光转换光学系统被适当地设置,以便有效地获得均匀的照明效果。 构成十字分色棱镜70的四个棱镜的垂直角脊71配置成与光轴正交,偏光转换光学系统3被设置成使得包括垂直角脊71和光轴的平面和 半波长相位膜32的延伸方向彼此正交的方向,并且构成第一和第二透镜阵列21和22的多个线性凸透镜阵列的透镜列的移动方向与该平面正交。

    • An imaging system is provided and includes an imaging lens and an imaging device such that the maximum diameter of an effective region of a point image becomes a size covering three or more pixels of light receiving pixels, the point image being projected onto a light receiving surface through the imaging lens from any position of X, Y, and Z directions. A signal processing unit in the imaging system executes restoration processing on first image data output from the imaging device that images an optical image of a subject projected onto the light receiving surface through the imaging lens, the restoration processing being executed to generate second image data equivalent to the first image data output from the imaging device when the resolving power of the imaging lens is higher.

    • A projection-type image display device includes a light source, converging optics, a rod integrator having a first optical axis, a light deflecting structure, and a light beam separating structure. The light beam separating structure directs light to a digital micromirror device and modulated light from the digital micromirror device along a second optical axis of a projection lens that projects an image formed by the modulated light on a screen. The rod integrator is between the light beam separating structure and the projection lens in the direction of the second optical axis and is outside the optical path of the modulated light beam from the digital micromirror device. The rod integrator may include a solid rod member and a leaky ray shielding member at least at one of the entrance end, the exit end, and around the solid rod member. The converging optics may include a parabolic reflector and an aspheric lens.
