1. A theatre system comprising:
- a screen having a horizontal dimension and a vertical dimension, one of the horizontal dimension or the vertical dimension being curved and another one of the horizontal dimension or the vertical dimension being straight;
a first projector for outputting first imaged light;
a first mirror positioned between the first projector and the screen for directing the first imaged light along a first axis to the screen;
a second projector for outputting second imaged light; and
a second mirror positioned between the second projector and the screen for directing the second imaged light along a second axis to the screen,wherein the first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and the second axis along the same one of the horizontal dimension or the vertical dimension of the screen that is curved.

Abstract
A theatre system is described that includes a screen and a projection system. The projection system includes a first mirror and a second mirror that are positionable within axes for imaged light and between projection lenses of projectors and the screen. The axes include a first axis and a second axis. The first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and second axis along a dimension by which the screen is curved.

16. A theatre system, comprising:
-
a screen with a surface having a gain to reflect light; a first projector for illuminating the screen with a first light having a first axis; a second projector for illuminating the screen with a second light having a second axis; a first mirror positioned between the first projector and the screen; and a second mirror positioned between the second projector and the screen, wherein the first mirror and the second mirror are configured to cause the first axis to be parallel to the second axis between (i) the first mirror and the second mirror and (ii) the screen, with a displacement between the first axis and the second axis, wherein the screen includes an area positioned to have a luminance difference measured at a view location between the first light and the second light reflected from the screen, resulting from (i) the displacement between the first axis and the second axis and (ii) a difference in the gain for the first light and the second light incident on the area, to cause the area to reflect the light with the luminance difference between the first light and the second light, wherein a curvature of the screen is along a dimension corresponding to the dimension of the displacement of the first axis and the second axis to cause the area with the luminance difference to shift away from a center of the screen. - View Dependent Claims (17, 18, 19, 20, 21)

22. A projection system, comprising:
-
a first mirror and a second mirror that are positionable within axes for imaged light and between projection lenses of projectors and a screen, the axes including a first axis and a second axis, wherein the first mirror and the second mirror are configured for causing the first axis and the second axis to be parallel to each other and to have a displacement between the first axis and the second axis along a dimension by which the screen is curved. - View Dependent Claims (23, 24, 25, 26, 27)

28. A method for use in a theatre system, comprising:
-
projecting first imaged light and second imaged light; directing, by a first mirror, the first imaged light along a first axis to a screen that is curved in one dimension; and directing, by a second mirror, the second imaged light along a second axis to the screen, the second axis being parallel to the first axis and defining a displacement with the first axis that is along the one dimension. - View Dependent Claims (29, 30, 31, 32)
