摘要： An object of the invention is to reduce the size and weight of a video projector by shortening the length of the arm of a mirror rotator and reducing the size of a mirror. A video projector comprises a plurality of projection lenses through which image light rays from a liquid crystal panel are extracted in a magnified manner; a reflective mirror for reflecting the extracted image light rays onto a screen; and a mirror rotator for rotating the reflective mirror so that the extracted image light rays can be reflected in particular directions. Among the projection lenses, some of the projection lenses located farther away from the liquid crystal penal are partially cut such that areas through which the image light rays do not pass are cut off to create a lens cut-off space. The mirror rotator is placed in the lens cut-off space.

摘要： A compact rear projection image display apparatus in which the projection distance in a projection optical system is substantially reduced and no reflection mirror is used, thereby eliminating a major cause of image trapezoidal distortion. The rear projection image display apparatus has a projection lens system which includes a first lens group with positive refractive power and a second lens group which further enlarges an image enlarged by the first lens group. The projection lens system enlarges and projects an image displayed on an image display device, on a transmission screen. No reflection mirror is provided between the second lens group and the transmission screen and the image enlarged by the second lens group is directly projected on the transmission screen.

摘要： A projection optical unit has two lens groups. A first projection optical unit disposed closest to an image display element, temporarily forms a first enlarged image (magnification: M1) at the image display element side, rather than at a second projection optical unit. The first enlarged image is subsequently projected in an enlarged form (magnification: M2, wherein M2>M1) onto a screen via the second projection optical unit. A field lens group having positive refractive power is disposed between the first projection optical unit and the second projection optical unit. Consequently, the relationship between F2, which is the F-value of the second projection optical unit, and F1, which is the F-value of the first projection optical unit, becomes F2=F1/M1, whereby it is possible to realize very-wide-angle imaging at a field angle exceeding 90 degrees.
摘要翻译：投影光学单元具有两个透镜组。靠近图像显示元件设置的第一投影光学单元在图像显示元件侧暂时形成第一放大图像（倍率：M 1），而不是在第二投影光学单元处。第一放大图像随后经由第二投影光学单元以放大的形式（倍率：M 2，其中M 2> M 1）投影到屏幕上。具有正折光力的场透镜组设置在第一投影光学单元和第二投影光学单元之间。因此，作为第二投影光学单元的F值的F 2与作为第一投影光学单元的F值的F 1之间的关系变为F 2 = F 1 / M 1，由此可以在超过90度的场角实现非常广角成像。
