电脑生成图像（英文：Computer-generated imagery，缩写：CGI），简称电脑成像，旧称电脑绘图（英文：Computer Graphics，缩写：CG），是指使用电脑产生的影像，更精确的如应用在影片中的三维特效，还有在电视节目、广告及印刷媒体中也很常见。在电脑游戏中常使用的即时运算图形都属于电脑生成图像的范围，也有些是用来做过场或是介绍用页面，有时这被称为全动态视频。

Computer-generated imagery (CGI for short) is the application of computer graphics to create or contribute to images in art, printed media, video games, films, television programs, shorts, commercials, videos, and simulators. The visual scenes may be dynamic or static, and may be two-dimensional (2D), though the term "CGI" is most commonly used to refer to 3D computer graphics used for creating scenes or special effects in films and television. Additionally, the use of 2D CGI is often mistakenly referred to as "traditional animation", most often in the case when dedicated animation software such as Adobe Flash or Toon Boom is not used and/or the CGI is hand drawn using (a) tablet(s) and/or mouse.
