利用计算机视觉对1922-2025年间5205部电影进行大规模分析，测量镜头距离演变，揭示技术变革影响及性别与动画中的镜头规范差异。
AI 中文摘要
计算机视觉和人工智能的兴起使得大规模计算测量的新形式成为可能。我们将这些技术应用于一个包含1922年至2025年间在影院放映的5,205部数字化电影的深度收藏（涵盖流行、知名和独立电影），以追踪电影传达信息的最基本方式之一的发展：通过操纵摄像机与其主体之间的空间。这项工作发现了随着声音和电视新技术的兴起而出现的突变，使我们能够以实证的方式揭示性别差异（女性尽管银幕时间远少于男性，却不成比例地成为更近景镜头的对象），并说明动画电影如何既继承又突破真人电影制作的规范。
英文摘要
The rise of computer vision and artificial intelligence has made possible new forms of large-scale computational measurement. We apply these techniques to a deep collection of 5,205 digitized films viewed in theaters between 1922-2025 (covering popular, prestigious, and independent movies) to trace the development of one of the most fundamental ways through which film communicates: by manipulating the space between the camera and its subject. This work finds abrupt changes with the rise of new technologies in sound and television, and allows us to shed an empirical light on gender disparity (women, despite having substantially less screentime than men, are disproportionately the subject of closer shots), and illustrate how animated films both inherit and break free from the norms of live-action filmmaking.
