Abstract

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.

摘要

VideoToolbox是一个免费的包含两百个用于Macintosh计算机的C语言子程序的集合，它可校准并控制计算机显示接口，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用于生成描述所需图像的数字。而底层的、特定于计算机的VideoToolbox子程序则控制将这些数字转换为电影的硬件。超越特定的计算机和语言，我们讨论计算机显示接口的本质，以及如何对其进行校准和控制。
