Screen and projector with spherical lens array
First Claim
1. A screen, comprising:
- a lens array having a plurality of spherical lens elements,a vertical length of each of the plurality of spherical lens elements, along a vertical direction, extending substantially through centers of respective spherical lens elements, and a horizontal length of each of the plurality of spherical lens elements, along a horizontal direction, extending substantially through centers of respective spherical lens elements, being set such that the horizontal length is larger than the vertical length, the horizontal direction being substantially orthogonal to the vertical direction; and
a curvature center position of any one of the plurality of spherical lens elements being arranged to be positioned at substantially a half of the first length along the first direction with respect to a second curvature center position of an other of the plurality of spherical lens elements, the other of the plurality of spherical lens elements being adjacent to the one of the plurality of spherical lens elements in the second direction.

Abstract
A screen includes a lens array having a plurality of spherical lens elements. A first length of the spherical lens elements, along a first direction at substantially a center of each of respective spherical lens elements, and a second length of the spherical lens elements, along a second direction at substantially the center of each of the respective lens elements and substantially orthogonal to the first direction, are set such that the second length is larger than the first length. A curvature center position of any one of the plurality of spherical lens elements is arranged to be at substantially a half of the first length along the first direction, with respect to a curvature center position of another spherical lens element adjacent to the lens element in the second direction.
