二、镜头焦距组合与影厅水平视线设计在影厅设计中,正常程序是根据所需容量确定影厅平面形式及尺寸,以及相关的放映机房、门厅等的位置,故放映距离L′(放映镜头至银幕中心的距离)是已知数。这既决定了银幕影像的尺寸,又同时决定了该尺寸与最大视距X_(max)的比值。而成为放映工艺设计与建筑工艺设计间的接
Second, the lens focal length combination and the horizontal view design of the theater In the design of the hall, the normal procedure is to determine the plane form and size of the hall according to the required capacity, and the position of the associated projector room, hall, etc., so the projection distance L′ (screening) The distance from the lens to the center of the screen) is a known number. This determines both the size of the screen image and the ratio of this size to the maximum line of sight X_(max). It becomes the connection between the exhibition process design and the architectural process design
