Throw (projector) : ウィキペディア英語版 | Throw (projector)
In film terminology, throw is the distance of a movie projector from the screen. It is the distance the image is ''thrown'' onto the screen, and it has a large effect on screen size. Often in home theatre individuals lack the correct throw distance in the room but this can be corrected by use of a ''short throw lens''. There are also "long throw" lenses available. A related term, throw ratio, refers to the ratio of the distance to the screen (throw) to the screen width. A larger throw ratio corresponds to a more tightly focused optical system.
