摘要： A projector includes an anamorphic prism optical system for converting an aspect ratio of an irradiation region on which the video light is irradiated. The anamorphic prism optical system includes a first prism set and a second prism set. The first prism set is obtained by combining a first prism and a second prism, and the second prism set is obtained by combining a third prism and a fourth prism. The first prism, the second prism, the third prism, and the fourth prism are respectively rotatable around rotation axes thereof, and a space between the first and second prism sets is adjustable in association with the rotation of the first prism, the second prism, the third prism, and the fourth prism.

摘要： An optical modulation device side lens group has different powers in the longitudinal direction and the lateral direction of a liquid crystal panel. Therefore, as the entire system of the optical projection system, the optical modulation device side lens group has different magnification in the longitudinal and lateral directions. Therefore, it is possible to make the aspect ratio of an image of the liquid crystal panel different from the aspect ratio of an image projected on a screen. That is, conversion can be performed on an aspect ratio. At this time, a distance p between each focus or a diaphragm and the screen SC side end surface of the optical modulation device side lens group satisfies the conditional expressions, so it is possible to achieve a predetermined or higher telecentricity in both states, that is, a first operating state and a second operating state.

摘要： An object-side lens group has different power factors between the vertical and horizontal directions of a liquid crystal panel, and a projection system as a whole therefore has different focal lengths between the vertical and horizontal directions and hence different magnification factors between the vertical and horizontal directions, whereby the aspect ratio of an image on the liquid crystal panel can be set at a value different from the aspect ratio of an image projected on a screen. That is, the projection system can convert the aspect ratio, which is the ratio of the width to the height of an image. When the distance between a diaphragm and an extreme end surface of the object-side lens group on the screen side satisfies a predetermined condition, at least a certain degree of telecentricity can be provided both in the vertical and horizontal directions.
摘要翻译： 物体侧透镜组在液晶面板的垂直和水平方向之间具有不同的功率因数，因此整个投影系统在垂直和水平方向之间具有不同的焦距，因此垂直和水平之间的不同放大系数 方向，由此可以将液晶面板上的图像的纵横比设置为与投影在屏幕上的图像的纵横比不同的值。 也就是说，投影系统可以转换纵横比，即宽度与图像高度的比值。 当屏幕侧的隔膜和物体侧透镜组的前端面之间的距离满足预定条件时，可以在垂直和水平方向上至少提供一定程度的远心度。
