  • Patent number: 8408713
    Abstract: A lens array set for a projection apparatus is provided. The lens array set comprises a first lens array and a second lens array. The first lens array has a plurality of first lens units which are rectangle-shaped and a side thereof that defines the first direction. The second lens array, which is parallel with the first lens array, has a plurality of second lens units which has a rectangle shape and a side thereof that defines the second direction. Each of the second lens units is set correspondingly to each of the first lens units, and the center of each second lens unit and the center of each first lens unit are coaxial. A rotation angle is substantially defined between the first direction and the second direction depending on the difference between the rectangle shapes of the first and the second lens units. When adopting the present invention in the projection apparatus, the light source efficiently provides light for the micro-display.

  • Patent number: 8284452
    Abstract: A method is disclosed for screening color separations of a lenticular image with a lenticular frequency of the lenticular lenses needed for viewing the lenticular image. An amplitude-modulated halftone image is calculated for each of the color separations at a screen angle and at a screen frequency, the tangent of the screen angle being a rational number. For a specific color separation, a screen angle relating to the direction perpendicular to the image strips of the lenticular image is defined, a pair of whole numbers whose ratio is equal to the tangent of the screen angle is determined, and the screen frequency of the color separation is calculated as the product of the lenticular frequency and the square root of the sum of the squares of the two whole numbers.
