VideoController是一个免费的Macintosh计算机的200个C子程序的集合，用于校准和控制计算机显示界面，以创建精确指定的视觉刺激。像MATLAB这样的高级平台无关语言最适合创建描述所需图像的数字。低层次的、计算机专用的VideoSwitch例程控制将这些数字转换成电影的硬件。超越特定的计算机和语言，我们讨论了计算机显示接口的性质，以及如何校准和控制它。
The VideoToolbox is a free collection of two hundred C subroutines for Macintosh computers that calibrates and controls the computer-display interface to create accurately specified visual stimuli. High-level platform-independent languages like MATLAB are best for creating the numbers that describe the desired images. Low-level, computer-specific VideoToolbox routines control the hardware that transforms those numbers into a movie. Transcending the particular computer and language, we discuss the nature of the computer-display interface, and how to calibrate and control it.
